Lamborghini Gallardo LP 560-4 Spyder – A dynamic experience of unparalleled intensity

With the new Gallardo LP 560-4 Spyder, Lamborghini has created a driving experience like absolutely no other – fascinating design, breathtaking performance and extreme handling characteristics come together with all the sensual intensity and open-air pleasure that only a soft top super sports car can deliver.

An even more powerful engine, permanent all-wheel drive and an all-new chassis mean that the Gallardo LP 560-4 Spyder offers yet another significant increase in performance against its predecessor. With its innovative design, the new LP 560-4 Spyder takes the unique Lamborghini styling ethic to the next level; the Spyder displays this powerful and elegant design language with even greater distinctiveness, making it all the more unmistakable.

The Gallardo LP 560-4 has been on the market since early 2008, as the successor to the most successful Lamborghini of all-time – since 2003, more than 8,500 models bearing the Gallardo name have left the production facility in Sant'Agata Bolognese.

'The LP 560-4 is the next step in a huge success story,' says Stephan Winkelmann, President and CEO of Automobili Lamborghini. 'With the Spyder, we are now unveiling a car that is, quite simply, a new dimension in the latest Gallardo range. It is an entirely new model which builds on the substantial technical and design attributes of the Gallardo LP 560-4 production strategy. The new Gallardo LP 560-4 Spyder is a simply breathtaking automobile – and utterly unparalleled in its commitment to extreme motoring.'

In its new generation, the Gallardo Spyder represents more than ever before automotive passion in its purest form. As in the Coupé, its enormous power is delivered by the new 5.2 liter V10 with an output of 560 horsepower (412 kW) at 8,000 rpm. The increase in 40 horsepower (29 kW) over its predecessor, as well as the 44 pound (20 kilogram) reduction in vehicle weight, improves the power-to-weight ratio to 6.10 pounds (2.77 kg) per horsepower, thus improving performance even further.

The LP 560-4 Spyder takes only 4.0 seconds to sprint from 0 to 62 mph (0 to 100 km/h), reaching 124 mph (0 to 200 km/h) in only 13.1 seconds and going on to a top speed of 201 mph (324 km/h). The new driveline, featuring the 'Iniezione Diretta Stratificata' direct fuel injection system also makes for impressive efficiency. Despite the considerable increase in performance, fuel consumption and CO2 emissions have been reduced by a staggering 18 percent.

Engineers at the Ufficio Tecnico Lamborghini, Sant'Agata-based Technical Department, have also improved traction, handling and stability at high speeds. The redesigned four-wheel drive transmission, the new suspension, the improved stiffness of the Spyder bodyshell and the optimized aerodynamics all contribute to the overall improvements in the vehicle, as do the reduced weight and decreased friction throughout the components.

Thus the Gallardo LP 560-4 Spyder presents itself as a razor-sharp super sports car with the precision reactions of a high-performance athlete. The car is also surprisingly suited to long-distance driving and, despite its extreme performance capabilities, is easy to control while maintaining utmost stability. Above all, the impressive Lamborghini technology takes on a new, intense edge in the Spyder, with the glorious feel of the open air rushing by.

The style
Powerful elegance

Every Lamborghini is a high-performance athlete. Its sensuality is based on precision, performance and on spontaneous action. A Lamborghini's elegance is that of sheer, pure power. This DNA of the Lamborghini brand is taken to the next level with every new car by the Centro Stile. Thus the Gallardo LP 560-4 Spyder displays the precise lines and clean surfaces of a minimalist design ethos that resists ornamentation or embellishment of any kind. Even more than the Coupé, the Spyder places emphasis on the powerful basic wedge form, complemented by the tightly cut soft top.

Each evolution of the Lamborghini form is strictly dictated by the demands of function. The redesigned front end lends the LP 560-4 a firm, low stance that also contributes to its aerodynamic efficiency. In line with the increased engine output, the enlarged and clearly accentuated air intakes increase the air flow critical to such a high-performance automobile. The spoiler, positioned low between the air intakes, improves aerodynamic stability at high speeds.

Characteristic LED daytime running lights

The new headlights have characteristic daytime running lights integrated beneath the bi-xenon lamps. 15 LEDs are arranged in a Y form, with the same pattern repeating in the rear tail-lights. The rear and brake lights were inspired by the Miura concept, the Murciélago LP 640 and the Reventón. The Y-shaped elements are now signature features of contemporary Lamborghini models, appearing most recently in the Estoque concept car, the innovative super sports sedan from Sant'Agata.

The completely redesigned rear gives new meaning to the term 'powerful elegance'. The rear lights, air cooling vents, bumper and diffuser are precisely arranged to add tremendous visual breadth to the LP 560-4 Spyder, while sustaining its firm bond with the road surface. In addition, the streamlined covers left and right of the bonnet accentuate the powerful shoulders and the taut lines of the new Gallardo.

Significantly improved aerodynamics

The new exhaust system is beautifully finished by four chrome-plated tail pipes. The rear diffuser has been redesigned to deliver more downforce and, together with the smooth underbody, it contributes to the vehicle's excellent directional stability, even at very high speeds. Overall, aerodynamic efficiency in terms of downforce has been improved significantly in comparison with its predecessor - the Gallardo LP 560-4 Spyder tackles fast curves with even greater refinement.

The purist approach to design is perfectly complemented by the immaculate attention to detail demonstrated by the designers at Sant'Agata Bolognese. The fuel and motor oil fill caps, intricately-crafted from aluminum bear testimony to this, as does the rear view camera, which has been integrated into a small fin in the automatically-deploying rear spoiler, as well as the finely-detailed grilles in the exhaust tail pipes.

Soft top perfectly suited to everyday use

The flow of the lines, regardless of whether the top is up or down, clearly demonstrates that the Spyder is a fully self-contained model within the Gallardo range. Compared with the Coupé, the open top version comes across as just a little more radical; its shoulders have been raised slightly in order to make room for the soft top.

The fully-lined fabric top – available in black, blue, grey and beige – is operated via two switches located on the center console. They set in motion a choreography that is over in just 20 seconds. One hydraulic pump, six hydraulic cylinders, one electric motor and two electric actuators work together to perform this technical ballet.

Rear windscreen functions as wind deflector

When the soft top opens, the rear windscreen disengages first, sliding downwards to avoid obstructing the remainder of the process. Four cylinders slightly raise the rear-hinged engine cover, before the hood folds gracefully into a stowage compartment located in front of the engine bay. Finally, the large engine cover made from a lightweight carbon fiber composite closes once more and the rear windscreen returns to its original position to function as a wind deflector. A switch mounted on the dashboard will stow the rear windscreen if preferred – even when the top is closed.

Whether open or closed, the Gallardo Spyder's soft top is designed for unrestricted high speeds. In order to ensure maximum safety, Lamborghini engineers have integrated two spring-loaded rollover bars behind the seats. Controlled by a sensor, they deploy in only 250 milliseconds should a potential roll-over situation arise. The seat belt tensioners spring into action at the same time.

The bodyshell
Intelligent lightweight design

Weight is undesirable in a sports car and lightweight design is good for dynamics. Aluminum is much lighter than steel – which is why the bodyshell of the Gallardo LP 560-4 Spyder has an aluminum structure that is more lightweight, yet stiffer. With its lighter engine, the two-seater boasts a dry weight of only 3417.2 Ibs (1,550 kg) – 44 pounds (20 kg) less than its predecessor.

The design of the Gallardo LP 560-4 Spyder utilizes the ‘spaceframe construction method.' Cast aluminum nodes and extruded profiles form its frame, with integrated friction-locked and form-fitted aluminum panels creating the bodyshell. The bodyshell is not only extremely light, but also displays exceptional torsional stiffness and safety characteristics, thus forming the basis for the extraordinary handling characteristics of the LP 560-4. The aerodynamic underbody panel is also integrated into the overall design for structural stiffness. The Spyder incorporates specially-developed additional stiffness elements within the spaceframe to compensate for the absence of a fixed roof.

Integrated pedestrian protection system

The bodyshell also incorporates the highest levels of passive safety. The Gallardo LP 560-4 Spyder even fulfils European directives for pedestrian protection that are not yet mandatory. Furthermore, the geometry of the entire front end of the car has been optimized, with a special combination of materials behind the front bumper that serve to absorb impact forces.

The interior
Luxurious individuality

Despite its low exterior height, the Gallardo LP 560-4 Spyder welcomes its passengers with a spacious interior – even when the top is closed. The sports seats are upholstered in either fine leather or Alcantara® and provide firm hold and support. The seats are mounted low, as is typical for sports cars, and behind them is additional luggage space to complement the 110 liter capacity luggage compartment at the front of the vehicle.

The wide middle console is one of the elements that characterize the impression of sporty dynamism in the interior. It accommodates the standard Lamborghini audio and multimedia system, as well as the dual-zone climate control. Between these two units is a newly designed module housing classically elegant toggle switches. Seven instrument dials boasting new graphics provide the driver with essential engine data, while a multi-functional display between the speedometer and rev counter furnishes him with important information from the on-board computer.

Highest quality workmanship

The Miura and the other models of the 60s were characterized by their excellent quality of workmanship, which was far beyond the general standards of the day. Lamborghini has built extensively on this tradition, and to this day delivers automobiles of the highest standards.

The Gallardo LP 560-4 Spyder indulges with materials of the highest quality in both look and feel. Leather interior choices include a range of colors and stitching in matching or contrasting tones. As an optional extra, Lamborghini can deliver the Gallardo with an expanded range of leather or Alcantara® equipment, as well as carbon packages, where elements like the surround for the air-conditioning control panel, the handbrake and the gear-stick console are finished in carbon fiber composite. The Ad Personam individualization program fulfils personal preferences – at the end of the day, a new Lamborghini has to fit in perfectly with the lifestyle of its owner.

The engine
Extreme power in every situation

The engine of the Gallardo LP 560-4 Spyder is a completely new development. All that remains is the number of cylinders, - that magical ten - which provides a perfect synthesis of high-revs, pulling power, athletic agility, compact dimensions and low weight that is unique within this performance class.

The engine has a displacement of 5.2 liters (5204 cm3 ), generating an extreme 560 horsepower (412 kW) at 8,000 rpm – giving class-topping output per liter of 107.6 horsepower. The engine delivers a maximum torque of 398 lb-ft (540 Nm) at 6,500 rpm. The ample torque curve guarantees outstanding thrust at all engine speeds. With acceleration of 4.0 seconds from 0-62 mph (0-100 km/h) and a top speed of 201 mph (324 km/h), the Gallardo LP 560-4 Spyder shoots into the orbit of the most extreme high-performance sports cars and is only one km/h less swift than the LP 560-4 Coupé.

Even more astounding is the fact that engineers at Sant'Agata succeeded in lowering the fuel consumption and CO2 emissions of the super sports car by 18 percent, despite a considerable improvement in performance. Relative to engine power and performance, the average fuel consumption of the Gallardo LP 560-4 Spyder e.gear is astonishingly low at only 16 mpg combined (20 hwy/13 city) (14 liters per 100 kilometers).

Perfect weight distribution, optimal dynamics

The engine in this new model is also located longitudinally behind the driver – hence the model denomination 'Longitudinale Posteriore.' The mid-engine concept is peerless in sports car design, creating the basis for the perfect weight distribution of the LP 560-4 Spyder of 43 percent on the front axle and 57 percent on the rear. In combination with the permanent all-wheel drive transmission, it guarantees the Gallardo's superior handling stability in all situations.

Low mass for impressive high-revving

The cylinder bore surfaces of the new Lamborghini ten-cylinder are made of a hypereutectic aluminum alloy. The hard silicon crystals of the bore surfaces are chemically released following the honing process. The connecting rods are made from forged steel and the pistons from aluminum alloy. The systematic reduction of mass and internal friction contributes to the engine's impressive high-revving characteristics.

The engine is unusually wide for a V10, with a cylinder angle of 90 degrees. The advantage of this layout is the lower center of gravity. The dry sump lubrication serves the same purpose, as well as guaranteeing a reliable supply of oil even during extreme lateral acceleration on the race track.

Direct fuel injection makes for efficient combustion

The new V10 uses the direct fuel-injection system 'Iniezione Diretta Stratificata' as an innovative way to optimize performance in all conditions, while achieving moderate fuel consumption. The fuel is injected directly into the combustion chamber from a common-rail system at pressures of up to 100 bar via laterally-position injectors. This ensures the perfect 'tumble' of the homogeneous fuel/air mixture and forms the basis of highly efficient combustion.

Direct injection boosts the extremely efficient full-load performance of the V10, reduces its knock sensitivity, provides an internal cooling effect and thus facilitates a very high compression ratio of 12.5:1. The cylinder heads have been optimized to deliver a rapid charge cycle, while the variable valve control system on all four camshafts improves charge efficiency across the entire engine speed range.

Transmission
All-wheel drive refinement

Such extreme power must be delivered to the road safely. The driver of a Gallardo LP 560-4 Spyder can thus rely on the viscous traction permanent all-wheel drive system – the number 4 in the model name serves as a reminder of this. Lamborghini introduced this system as early as 1993, with the Diablo VT – and for good reason. Four driven wheels achieve more grip than two and permit earlier acceleration when exiting a curve.

Located in the driveline is a central viscous coupling, which requires no electronic control. In this Lamborghini-specific configuration, driving power is distributed between front and rear at a standard ratio of 30:70, adapting to variations in road conditions within a matter of milliseconds. A mechanical differential on the rear axle providing up to 45% limited slip, and an electronic differential lock at the front complete the all-wheel drive system.

Superior traction and handling

It is not only maximum traction that benefits from permanent all-wheel drive, but also the car's clearly superior handling. Ultimately, each wheel can only transfer a certain amount of power to the road. As the drive power is distributed to all four wheels via the viscous traction system, there is thus greater potential for directional control. These reserves in every situation are what distinguish a perfectly made sports car.

With all of that engine thrust, changing gears in the Gallardo LP 560-4 is also one of the most exciting aspects of this vehicle. It remains a matter of personal preference whether the driver uses the short gear stick to work manually through the precision motion of the six-speed gearbox, or whether he chooses to let his fingertips control the e.gear's paddle-shift system located behind the steering wheel – the option preferred by the majority of Lamborghini customers.

Shift times reduced by 40 percent

The automated e.gear transmission has been completely redesigned and improved in all aspects. The complete system is not only considerably lighter, but the time required to change gear in corsa mode has also been reduced by 40 per cent. The driver can change gear manually using the shift paddles mounted on the steering wheel – or he can leave it entirely up to the automatic mode, which ensures extremely refined dynamics.

If the driver changes gear manually using the steering wheel paddles, he can choose from three different drive programs. Alongside the standard program, the Gallardo also offers the sport mode with even shorter shift times, while the corsa program delivers optimum engine acceleration.

ESP is active in all drive programs, engaging later in the sport and corsa modes and reducing the impact of the traction control. The corsa mode also permits greater drift and enables the complete dynamic spectrum of the LP 560-4 Spyder to be appreciated on the race track – while still leaving plenty of room for safety. The Lamborghini thrust mode facilitates maximum acceleration from a standstill. The throttle valve angle and clutch travel have been optimized specifically for this purpose.

The chassis
Hi-tech components with Lamborghini expertise

The predecessor to the Gallardo LP 560-4 Spyder was already one of the world's best super sports cars in terms of handling, precision and driving stability. However, the latest model delivers an even more intense driving experience across the board. The new chassis improves the car's handling, its driving comfort and its directional stability at high speeds.

The chassis of the Gallardo LP 560-4 Spyder is uncompromisingly hi-tech. Its technical design comes directly from motorsport. The aluminum double wishbones with re-designed kinematics encircle the wheels, while the springs and shock absorbers have been recalibrated for stiffness and optimum grip. The rear axle now has an additional track rod, bringing an extra element of control to the super sports car.

One all-new development is the rubber-metal bearings. These truly hi-tech components contribute to the unique Lamborghini dynamics with intelligent design and specific material combinations. The precise set-up of the springs and dampers has been adjusted to accommodate the slightly higher weight of the Spyder to give it exactly the same characteristics as the Gallardo Coupé.

Intense road holding

The rack and pinion steering works with relatively little power assistance – giving the driver a direct and close connection with the road, and providing intense experience of the power and forces at play. The steering has its own cooling system for the power steering fluid.

Precise, breathtakingly fast, yet stable and free from surprises - the Gallardo's dynamics deliver a sensuous experience. At the limit, the tires (235/35 ZR 19 front and 295/30 ZR 19 rear) appear to bond with the road surface. The wheels are clad in Pirelli P-Zero series tires, specially developed for Lamborghini. They boast particularly low rolling resistance and thus contribute to reduced fuel consumption without any compromise in performance. At speeds of more than 75 mph (over 120 km/h), an automatically-deploying rear spoiler increases the down force on the rear axle. It works together with the specially formed underbody, which directs the airflow under the car.

Optional carbon fiber ceramic brake system

The new brake system comes with brutal stopping power. At the front, eight-cylinder Brembo calipers grip 14.37 in (365 mm) diameter discs, while four-cylinder calipers and 14 in (356 mm) discs take up the rear. The new disc ventilation also improves brake fade under extreme load conditions.

Highly stable carbon fiber ceramic discs are available as an option. At the front the CCB (Carbon Ceramic Brake) discs measure 15 in (380 mm) diameter and at the rear 14 in (356 mm). They deliver improved performance with reduced weight. The CCB system significantly reduces weight, which improves dynamics and comfort.

Equipment and trim - Top-class individuality

Lamborghini has equipped the Gallardo LP 560-4 Spyder with an exceptionally sporty standard equipment package that includes the automatic top; driver, passenger and side air-bags; dual-zone climate control with sun regulator; stereo system with USB interface; sports seats with electrically adjustable back rests; leather upholstery and bi-xenon headlamps with LED daytime running lights. The new series production 'Apollo' wheels feature a double-spoke design.

A range of optional extras brings additional comfort and convenience – including a navigation system, a hands-free Bluetooth® mobile phone connection, anti-theft device and a rear view camera. A further option is a lifting system for the front axle – which raises the body at the touch of a button to ease negotiation of obstacles. New options include black painted 'Cordelia' wheels.

The possibilities available in the 'Ad Personam' individualization program are virtually inexhaustible. Behind this program stands the philosophy that a super sports car, as a significant expression of the personality of its owner, should fit perfectly to his desires and expectations. This is particularly true for a car as highly emotional as the Spyder. As a consequence, the finest exclusivity is the trademark of Lamborghini's individualization program. 'Think the Impossible' is its motto.

'Ad Personam' offers a host of options to bring highly individual style to both the interior and exterior of a Lamborghini. One new highlight in the program is three matte-luster color options - Nero Nemesis (matte black), Bianco Canopus (matte white), Marrone Apus (matte brown). These colors, applied using a specialist and highly sophisticated process, bring particular emphasis to the purist precision of Lamborghini design.

Next generation Porsche Cayman with increased power and efficiency

Porsche is presenting the second generation of the mid-engined Cayman sports coupe. The highlight is the new, flat-six ‘boxer' engines, developed to incorporate new technical features from the ground up, providing not only more power, but also significantly greater fuel efficiency.

A further improvement of both fuel economy and performance is guaranteed by the Porsche Doppelkupplungsgetriebe (PDK), the new double-clutch gearbox now available as an option on both the Cayman and Cayman S.

Newly-developed' boxer' engines deliver more power on less fuel

The Cayman now has an engine displacing 2.9-litres, which develops 265 bhp (195 kW), an increase by 20 horsepower over the prior 2.7-litre model.

The 3.4-litre power unit in the Cayman S now features Direct Fuel Injection, and delivers 320 bhp (235 kW), up by 25 bhp.

These developments see the engines fitted to the Cayman and Cayman S coupes offering more horsepower than those in the Boxster roadster. This move emphasises the sports driving orientation of the Cayman and further differentiates the coupe.

An outstanding power-to-weight ratio of 4.2kg/bhp on the Cayman S in particular ensures optimum driving dynamics. For example, the Cayman S with PDK and Launch Control (featured in the optional Sports Chrono Package Plus) accelerates from 0-62mph (0-100 km/h) in 4.9 seconds, setting the benchmark in the range.

When combined with the PDK transmission, the new 2.9-litre engine of the Cayman clearly breaks through the 30.0mpg fuel consumption boundary. Indeed, the figure of 31.0mpg (9.1 litres/100km) is approximately 10 per cent better than the previous model with the Tiptronic S automatic transmission. Increasing fuel economy by an even more significant 15 per cent to 30.1mpg (9.4 litres/100km), the 3.4-litre Cayman S with PDK offers an even greater saving over its predecessor with Tiptronic S.

In parallel with the improvement in fuel economy, so emissions of the engines have decreased also. Depending on model, emissions have been reduced by up to 16 per cent. The Cayman with the standard six-speed manual gearbox emits 221g/km CO2, and 214g/km CO2 when fitted with PDK. The Cayman S manual emits 223g/km CO2, and 221g/km CO2 with PDK.

Significantly, these developments move every Cayman model – whether manual or PDK – into Band F for Vehicle Excise Duty and company car taxation purposes.

Direct Fuel Injection standard on 3.4-litre S engine

The driver benefits from a further advantage of direct injection every time they touch the throttle pedal: with fuel being injected fractions of a second prior to combustion, the engine responds more directly and spontaneously to even the slightest movement of the driver's right foot. This is not only the case when accelerating, but also when lifting off the throttle, for engine speed drops more quickly and smoothly since there is no residual fuel left in the intake manifold which might otherwise prolong the combustion process.

Depending on engine load and speed, fuel is injected into the combustion chamber at a pressure of 120 bar. The big advantage is that unlike conventional intake manifold injection, direct fuel injection serves to form the fuel/air mixture directly in the combustion chamber. This better mixes the air and fuel in the cylinder, establishing an important prerequisite for clean and complete combustion. This ensures the ‘homogeneous' operation of the power unit with a consistent balance of the fuel/air mixture in the combustion chamber at all times and under all running conditions. Such smooth operation guarantees optimum combustion and maintains low emissions, across a range of fuel qualities.

A coupé of distinction

While instantly recognisable as a Porsche sports car, the Cayman is individual in its design. Originally launched in 2005, the characteristic silhouette of the Cayman has remained fresh and contemporary. Its distinctive coupé lines are combined with a long wheelbase and a rear aspect that slopes gently downwards. From the rear, the Cayman is defined by a large, opening rear lid, powerfully sweeping wheel arches and an automatically extending spoiler.

The rear lid opens upwards to provide access to the 260 litre luggage compartment. This, in conjunction with the 150 litre capacity luggage compartment in the nose, plus numerous additional storage compartments, ensures that this two-seater sports car combines real functionality with elegant aesthetic form.

As is Porsche tradition, the styling of the next generation two-seater Coupe has evolved subtly. However, it is clearly distinguishable from outside through its newly-designed nose and tail. The new halogen headlights with their integrated direction indicators are reminiscent of the lights on the Carrera GT, and the new LED rear lights tapering to the outside are integrated elegantly in the remodelled bodywork.

The rod-shaped side lights in LED light conductor technology add distinction to the car's looks, which are further enhanced through their horizontal arrangement in the outer air intakes. Yet a further highlight is provided by the round fog lamps featured as standard.

For the first time the Cayman is available with a Lights Package featuring bi-xenon headlights, dynamic cornering lights and LED day-time driving lights. Replacing the fog lamps, these light units are made up of four LEDs arranged in round light units like the eyes on dice.

PDK: quickly shifting gears, reducing fuel consumption

The Cayman is available with the Porsche-Doppelkupplungsgetriebe (PDK) carried over directly from motor sport, and replacing the former Tiptronic S torque converter automatic transmission. When equipped with PDK, the Cayman accelerates from 0-62 mph (100km/h) 0.1 seconds faster than with the manual six-speed gearbox.

Acceleration is particularly fast and dynamic with the optional Sports Chrono Package Plus featuring Launch Control; this offers maximum acceleration from a standing start and also a Race Track Gearshift Strategy for the fastest conceivable gear change as an exclusive highlight on the PDK models.

Benefiting from Launch Control, the respective models accelerate from a standstill to 62 mph (100 km/h) yet another 2/10ths of a second faster.

Porsche Doppelkupplungsgetriebe (PDK) – in detail

The next generation Cayman and Cayman S are available for the first time with the new Porsche Doppelkupplungsgetriebe (PDK), literally Porsche double-clutch gearbox. Offering no less than seven forward gears, the new gearbox combines the driving comfort of a torque converter-equipped automatic transmission with the dynamic manual gearshift functionality of a sequential racing gearbox. PDK also boasts an entirely automatic gearshift function, and replaces the Porsche Tiptronic S automatic transmission previously offered. Through its optimised and adaptive gearshift programmes, PDK further improves the acceleration of the Cayman models and reduces fuel consumption to an even lower level.

In principle, the PDK consists of a conventional manual gearbox and a hydraulic control system divided into two separate transmission units. Two wet clutches in radial arrangement, controlled hydraulically, and using oil for both cooling and lubrication, form the heart of the transmission. One clutch is for the first transmission unit with the uneven gear ratios (1,3,5,7) and reverse, and the other clutch is for the second transmission unit with the even gears (2,4,6). Via a number of pressure valves, the hydraulic control unit masterminds both the wet clutches and the shift cylinders activating the transmission ratio required.

The gearshift perceived by the driver comes not from the gears actually changing, but from the change of positive clutch engagement. In this case, the clutch on one transmission opens or disengages while the clutch on the other transmission closes or engages in a simultaneous process. The big advantage is an even faster gearshift than with a conventional manual gearbox or torque converter automatic transmission. The gears are already ‘in mesh' when shifting and the power of the engine need not be interrupted in the process.

PDK also reduces to a minimum transmission power loss courtesy of the high standard of mechanical efficiency in the double-clutch, and this manifests itself in fuel economy improvements of approximately 13 per cent compared with a conventional Tiptronic S transmission. PDK also offers an advantage in terms of weight – despite two additional gears, it weighs 10kg less than Tiptronic S.

To use the various functions of the double-clutch transmission, the driver can either shift gears by means of sliding buttons on the spokes of the new steering wheel, or via the new gear selector lever. The driver can press forwards to shift the gears up, and press them from behind to shift downwards. Alternatively, pushing the gear selector lever forwards shifts up a gear, and pulling it back shifts down. The option of PDK costs £1,961.

This PDK gearshift principle was first developed by Porsche for motor sport 25 years ago. Porsche works drivers benefiting from this technology were able to accelerate faster than their competitors and keep both hands on the steering wheel while changing gears, thus avoiding even the slightest distraction while shifting.

The seven-speed PDK shifts gears up to 60 per cent faster than a conventional automatic transmission, and naturally, gives the new Cayman models even better performance. And those in search of optimum driving dynamics have the option to combine PDK with Sport Chrono Package Plus, now featuring Launch Control.

Dynamic suspension and supreme brakes – new option of limited-slip differential

The suspension with its new set-up gives the new Cayman models a combination of even greater driving dynamics and enhanced comfort all in one. Modification of the valve control map on the steering gear serves furthermore to reduce steering forces, giving the Cayman more agile and spontaneous steering behaviour.

The wheels come in new designs and are half an inch wider than previously on the Cayman 2.9-litre model in order to accommodate the larger brake system of the S-models which are now fitted on the front axle. The Cayman and Cayman S feature the latest generation Porsche Stability Management (PSM) which now offers two new functions: Brake Pre-Loading and the Brake Assistant. Whenever the driver lifts off the throttle pedal very quickly – which is typical immediately prior to an emergency braking manoeuvre – the PSM hydraulic control unit builds up an appropriate level of pressure in the brakes before the driver even presses the brake pedal down, which has the effect of moving the brake pads slightly towards the discs, and ready for immediate action. This significantly improves brake response and shortens stopping distances accordingly.

When recognising that the driver is braking in an emergency due to the very fast operation of the brake pedal and a defined brake force, the PSM hydraulic control unit actively delivers the brake pressure required for maximum stopping power.

In conjunction with 18- and 19-inch wheels, the new models in the Cayman range are also available with a limited-slip differential on the rear axle. Locking action is 22 per cent under power and 27 per cent in overrun. This significantly improves both traction and stability, providing a substantially higher level of performance on winding roads, particularly on the race track. A further advantage is the more stable load change behaviour. At the same time, the mechanical differential, through its particular function, interacts perfectly with the electronic Automatic Brake Differential (ABD) for optimum traction control, the locking action delaying the tendency of one wheel to spin on a road surface slippery only on one side.

New audio and communication systems

The next generation Cayman features as standard the new CDR-30 CD radio. The new Porsche Communication Management (PCM) 3.0 complete with hard disc navigation is available as an option and when specified serves as the central control unit for all audio, communication and navigation features.

PCM 3.0 is more versatile, efficient and easier to use than before, standing out in particular through its touch-screen which enables the driver to select specific functions simply by pressing the appropriate key on the larger 6.5-inch monitor. PCM 3.0 is available with highly convenient voice control and, in conjunction with the optional, universal audio interface, can now be used also to control external audio sources such as an iPod®, USB stick, or Bluetooth.

Seat ventilation combined with seat heating is also available as an option.

Lexus Stages World Debut of All-New RX 350 and RX 450h

Lexus unveiled the all-new, next generation RX 350 and RX 450h hybrid. The vehicle that pioneered the car-based luxury utility vehicle segment when it launched in 1998, is completely redesigned and will continue to set new benchmarks in areas that have made it the best-selling luxury utility vehicle: innovation, styling, performance, utility and comfort.

At the heart of the new RX models are two improved powertrains. Entering its second generation, the RX 450h will feature an enhanced Lexus Hybrid Drive system with a 3.5-liter V6 gas engine that runs on a highly efficient Atkinson cycle. Combined with a new, more efficient inverter, the total system output will be 295 horsepower, 27 more horsepower than the current generation RX hybrid.

Another step in the Lexus Hybrid Drive's evolution is the addition of two new systems that improve its efficiency. The first is an exhaust-heat recovery system that reduces engine warm-up time allowing it to stop earlier, more often, and for longer periods. The result is an improvement in both fuel economy and emissions. The second is a cooled exhaust-gas recirculation system that reduces engine pumping losses, which also helps to improve economy.

The RX 450h features a front-wheel hybrid drive or an electronically driven, part-time all-wheel-drive (AWD) hybrid drive system, which supplies the rear wheels with the optimal amount of torque as conditions demand. Unlike mechanical AWD systems that reduce fuel efficiency via added weight and friction, the RX 450h's rear-mounted electric motor-generator allows all four wheels to perform regenerative braking, charging the hybrid battery more effectively.

The third generation RX 350 will be powered by an improved 275-horsepower, 3.5-liter V6 engine mated to an electrically controlled, sequential-shift six-speed transaxle. The all-wheel-drive version will feature an Active Torque Control AWD system that optimizes torque depending on driving conditions, resulting in improved efficiency and performance.

Both RX models feature a new, uniquely designed double-wishbone rear suspension that helps provide exceptional agility and control. Its distinctive design also allows for five percent more cargo volume and easier loading. To complement the new rear suspension and provide excellent dexterity and ride comfort, the front McPherson strut geometry was optimized.

The all-new RX models possess a number of Lexus-first technologies that enhance the ownership experience. An available Hard Disk Drive (HDD) navigation system has an all-new 'Remote Touch' controller that is both intuitive and ergonomic. Positioned on the center console, Remote Touch is as natural to the driver's hand as a computer mouse. It can also be customized to the desired level of haptic feedback. While RX will feature voice recognition as standard, the new navigation system will also include a new casual language voice-recognition system that acknowledges conversational commands. Standard XM® satellite-radio capability (requires subscription) is joined by XM NavTraffic and new NavWeather features.

The spacious five-passenger interior includes a new, thoughtfully constructed 'dual-zone cockpit' design. This intuitive layout helps the driver navigate the advanced interior of the new RX, which features two distinct yet integrated zones: a 'display zone' and an 'operation zone.'

The 'display zone' assists the driver via an eight-inch, navigation display that is set back in the dash for improved visibility. A white Organic LED multi-informational display ensures exceptional readability from a wide angle. An optional Heads-up Display reduces the need for excessive eye movement, and the use of high-intensity LEDs make the display bright enough to be read in direct sunlight.
The 'operation zone' provides access and control to a large range of information through the available 'Remote Touch' navigation controller and the steering-wheel-mounted multi-information switch.

The exterior of the all-new RX has a strong stance and powerful new body design with the goal of enhancing comfort and maneuverability. The inverted-trapezoid design in the front and the horizontally integrated rear are incorporated together via a pronounced shoulder along the RX's profile. Stylish molding around the side windows and at the base of the doors provides low-profile strength. Standard 18-inch aluminum-alloy wheels complement the exterior with a strong, sporty look, with optional 19-inch aluminum-alloy wheels providing another styling cue. While it has increased in nearly every dimension, overall aerodynamic advancement was aided by a specially designed undertray, resulting in a segment-topping 0.32 coefficient of drag (Cd).

The RX 450h hybrid will have its own unique styling features, including an exclusive grille, hybrid badging including blue-trimmed Lexus logos, unique front bumper, a special 19-inch optional wheel design, blue-tinted headlamps and taillamps, and optional LED headlamps.

The new RX is available with a selection of luxury and sport option packages, which include features like Lexus' exclusive Mark Levinson® Surround Sound system, a dual-screen rear-seat entertainment system, dynamic radar cruise control, and a Sports Package featuring a sport-tuned suspension.

The all-new RX will offer a wide-angle side view monitor. With a camera located under the passenger side-view mirror, the driver can check hard-to-view areas on the passenger side of the vehicle by simply selecting a button on the navigation screen or the steering wheel and view the camera image on the navigation screen.

True to its heritage, the RX's active and passive safety systems continue to be among the vehicle's most impressive features. Lexus' available Vehicle Dynamics Integrated Management (VDIM) seamlessly integrates individual systems like Vehicle Stability Control (VSC), Anti-lock Braking System (ABS), Hill Assist Control (HAC) and Traction Control (TRAC). It operates in a smooth proactive way via throttle, steering and braking to help prevent skids while cornering before the vehicle reaches its operating limits on slippery roads or other challenging conditions.

The available Pre-Collision System (PCS) relies on millimeter-wave radar technology to recognize a possible frontal collision and primes the brake assist and retracts the driver's and front passenger's seat-belt in anticipation of the crash. An intelligent Adaptive Front-lighting System (AFS) is available with HID low- and high-beam headlamps on both models, while the RX 450h also offers the AFS with LED low-beam and Halogen high-beam headlamps. Both anticipate the vehicle's location based on vehicle speed and steering angle, swiveling the front headlamps into the turn. An optional new automatic high-beam system detects light from oncoming vehicles, preceding vehicles or ambient sources and automatically switches from high to low beams.

Passive safety features include a class-leading 10 standard airbags on the new RX, including dual-stage driver and front-passenger airbags (including the Lexus exclusive twin-chamber front-passenger airbag), driver and front-passenger knee airbags, front and rear seat-mounted side airbags, and side-curtain airbags. It is also equipped with Lexus' front-seat active headrests, designed to help reduce a possible whiplash injury when in certain lower speed collisions from the rear.

The all-new 2010 RX 350 will go on sale next February, while the 2010 RX 450h will reach dealerships nationwide in the spring.
