New Design, New Technology

More powerful in every respect – that is how the second generation of the Porsche Cayenne is entering the market: With a striking face upfront on a wide and muscular body, with head­lights in brand-new design, and with broader, even more powerful-looking wheel arches, the optimised body makes a clear testimony to the Cayenne's upgraded technical features.

All three model variants feature even more powerful engines beneath the engine compart­ment lid, and for the first time boast direct gasoline injection. Engine size has been increased, and the eight-cylinder models feature Porsche VarioCam Plus variable valve control as another first-time achievement.

The result is an increase in engine power to 290 bhp (213 kW) on the six-cylinder and 385 bhp (283 kW) on the eight-cylinder. Maximum output of the Porsche Cayenne Turbo, in turn, is now exactly 500 bhp (368 kW).

Enhanced performance on less fuel

The introduction of Direct Fuel Injection and the significant improvement of aerodynamics with a drag coefficient of Cd = 0.35 on all three models benefits both performance and fuel economy, as well as other features, on all versions of the Cayenne. Top speed of the Cayenne is 227 km/h or 141 mph. The Cayenne S moves up this speed level quite signi­fi­cantly, rea­ching a top speed of 252 km/h or 156 mph. And at 275 km/h or 171 mph, the Cayenne Turbo is clearly the leader.

Despite this impressive performance, fuel consumption is down on the various models by more than 8 per cent in the New European Driving Cycle (NEDC), while under realistic driving conditions fuel economy is improved even more significantly by up to 15 per cent versus the former models.

PDCC: New, active anti-roll function

As an optional supplement to PASM Porsche Active Suspension Management, Porsche Dy­namic Chassis Control (PDCC) is now available as a brand-new feature. Two active anti-roll bars set off body roll in bends almost 100 per cent, with the body showing a detectable reaction under such circumstances only when the driver prefers a very sporting style of motoring. In practice, this means that PDCC improves both driving safety, handling in gene­ral, and the high standard of comfort offered by the Cayenne models. And when driving off the beaten track, PDCC allows maximum interaction and adjustment of the axles in the in­terest of enhanced traction.

Upgraded PSM for even greater safety

Featured as standard, PSM Porsche Stability Management comes with various new functions: It now pre-loads the brake system whenever appropriate, offers a Brake Assistant, features enhanced Trailer Stability Control, and comes with offroad ABS. These additional functions ensure an even faster reaction of the vehicle when applying the brakes, prevent the Cayenne from developing potentially dangerous pendulum action when towing a trailer, and optimise the brake effect of Porsche's Sports Utility on loose ground.

Fully controlled four-wheel drive for road and track

PTM Porsche Traction Management gives the Cayenne exceptionally superior driving characte­ristics on all kinds of roads and tracks. Via electronically controlled longitudinal locks, this permanent all-wheel-drive system is able to vary front-to-rear power distribution as required, depending on the respective situation. And featuring low-range transmission for offroad use, PTM also ensures absolutely excellent traction on heavy terrain.

Featuring Dynamic Curve Lights for the first time

The Cayenne Turbo comes as standard with new Dynamic Curve Lights supplementing the Static Curve Lights fitted so far. These Curve Lights are part of the bi-xenon headlight sy­stem designed and built for excellent illumination of the road ahead. The combination of Static and Dynamic Curve Lights offers outstanding advantages at both low and high speeds and is available as an option on the Cayenne and Cayenne S.

Rollover sensor for passive safety upgraded to a new standard

For the first time the new models in the Cayenne range come with a rollover sensor able in an emergency to trigger both the belt latch tensioners and curtain airbags, thus helping to reduce the risk of injury for all occupants in a rollover. Together with the six “regular" air­bags, this gives Porsche's Sports Utility an occupant safety and protection system once again setting the benchmark in the market.

New Models in the Porsche Cayenne Range: The Second Generation: Powerful and Dynamic

The Porsche Cayenne is entering its second generation in fresh and powerful design, with new engines and an even higher standard of driving dynamics. The “basic" version of Porsche's superior Sports Utility is now powered by a 290 bhp (213 kW) six-cylinder increased in size from 3.2 to 3.6 litres – offering an increase in maximum output over the former V6 by no less than 40 bhp or 29 kW.

Featuring a natural-aspiration V8 power unit up by 0.3 litres to 4.8 litres capacity, the Cayenne S now develops maximum output of 385 bhp (283 kW), 45 bhp (33 kW) more than before.

The increase in power on the eight-cylinder Cayenne Turbo with biturbo turbochargers is even more significant, the top model in the range now boasting exactly 50 bhp or 37 kW more in power than its predecessor, and thus raising the benchmark to precisely 500 bhp or 368 kW.

For the first time all three models come with direct gasoline injection giving the three ver­sions of the Cayenne not only significantly more power, but also a substantial reduction of fuel consumption: The introduction of direct gasoline injection bearing the name Direct Fuel Injection or DFI in Porsche's nomenclature serves to reduce fuel consumption of the indivi­dual models in the New European Driving Cycle (NEDC) by more than 8 per cent, with sa­vings of up to 15 per cent under realistic driving conditions.

More muscle, less air drag

The new front end with modification of the swept angle configuration and new front wheel arches with even more striking contour lines at the top accentuate the muscular stature of the second-generation Cayenne. The low-slung headlights now moved far to the outside and covered by clear glass help to give the new model its unique face and character.

This new design comes together with a significant improvement of aerodynamics, with the Cayenne’s drag coefficient down from Cd = 0.38 (V6) and, respectively, Cd = 0.39 (eight-cylinder models) to the same low level of Cd = 0.35 on all three versions of the new model. This substantial improvement is attributable to a whole range of modifications including, inter alia, brand-new spoilers on the wheels, a front spoiler lip extending further down than before, newly designed exterior mirrors, and a roof spoiler with enhanced aerodynamics and air flow conditions.

The new Cayenne comes on 17-inch wheels, the Cayenne S and Cayenne Turbo are fitted as standard with newly designed 18-inch wheels. And all models are now also available with 19-inch all-season tyres, while brand-new wheels in attractive ten-spoke (Sports Wheel) or multi-spoke (Sports Plus Wheel) design measuring 21 inches in size provide an even more sporting look combined with enhanced performance on the road. Yet a further benefit of these new wheels is that they are no heavier than the 20-inch wheels also available as an option.

New power units: Fuel Consumption Down, Engine Power Up

As before, the Cayenne comes with a V6 power unit as the “basic" engine. The increase in engine capacity to 3.6 litres is accompanied by a reduction of the cylinder angle from 15o to 10.6o, while the introduction of Direct Fuel Injection operating at a pressure from 40 – 120 bar provides not only a significant increase in engine power, but also boosts engine torque from 310 – 385 Newton-metres (228 – 283 lb-ft) in the interest of significantly enhanced performance: The Cayenne accelerates to 100 km/h or 62 mph in 8.1 seconds and reaches a top speed of 227 km/h or 141 mph – as opposed to 9.1 seconds and a top speed of 214 km/h or 133 mph so far on the former model.

The eight-cylinder power units combine Porsche's new DFI fuel supply system with the in­tro­duction of VarioCam Plus valve control. Featuring infinite valve timing and valve lift adjust­ment on the intake side, the 4.8-litre natural-aspiration power unit in the Cayenne S develops maximum torque of 500 Newton-metres/369 lb-ft (previously 420 Newton-metres/310 lb-ft) and accelerates the manual-gearbox model to 100 km/h two-tenths of a second faster than before in 6.6 seconds, with top speed now reaching 252 km/h or 156 mph (previously: 242 km/h or 150 mph).

Benefiting from two exhaust gas turbochargers, the eight-cylinder in the Cayenne Turbo now develops maximum output of 500 bhp together with peak torque of 700 Newton-metres or 516 lb-ft, accelerating the top model in the range to 100 km/h or 62 mph in just 5.1 seconds and providing a top speed of 275 km/h or 171 mph. This means an improvement in per­formance in the top model by half a second to 100 km/h, with top speed up by 9 km/h or 5 mph.

Despite this significant improvement of performance, fuel consumption in the New European Driving Cycle (NEDC) is down on all models: The manual-gearbox Cayenne consumes an average of 12.9 litres on 100 kilometres, equal to 21.9 mpg Imp or 0.3 litres less than its predecessor. And on the model with Tiptronic S automatic transmission, fuel consumption is down by an even more significant 0.6 litres.

The Cayenne S with manual gearbox now consumes 14.9 litres on average (19.0 mpg Imp), 0.9 litres less than the former eight-cylinder. And again, the Tiptronic S version is even more fuel-efficient, with average consumption of 13.7 litres/100 kilometres or 20.6 mpg Imp, an improvement by 1.2 litres over the former model.

Fitted with automatic transmission as standard, the Turbo comes with a reduction in fuel consumption form 15.7 to 14.9 litres/100 kilometres (18.0 to 19.0 mpg Imp), that is an improvement by 0.8 litres in overall terms.

The bottom line is that fuel economy in the NEDC is up by more than 8 per cent on some models. And under real-life driving conditions, that is driving in town, on country roads and on the German Autobahn, the new models even reduce fuel consumption by up to 15 per cent.

Reinforced transmissions

Both the Cayenne and the Cayenne S come as standard with a reinforced six-speed manual gearbox, while the Cayenne Turbo features Porsche's six-speed Tiptronic S automatic trans­mission now developed to an even higher level of perfection and available as an option also in the Cayenne and Cayenne S.
