Porsche skips right over the 2007 model year to roll out the \"second generation\" Cayenne sport utility vehicle (SUV), their best-selling model in North America. While the first Cayenne underscored the \"sport\" in SUV, this next Cayenne shows off an updated body design and bears an array of more powerful engines across the full model range. A new model for 2008, the 405-hp Cayenne GTS slots itself between the 500-hp Cayenne Turbo and the slightly less powerful 385-hp Cayenne S.

Model Lineup
Although it is not an entirely new design, the Cayenne has been heavily reworked for 2008-Porsche considers it a second-generation-and the lineup contains four different Cayenne models: Cayenne, Cayenne S, Cayenne GTS, and Cayenne Turbo. According to Porsche, while most manufacturers simply put larger engines and more luxury amenities in their more expensive models, Porsche's approach is more comprehensive: it includes increasingly effective braking systems and upgraded suspensions at the higher end of the lineup. However, there is no such thing as a base model Cayenne-even the standard Cayenne is outfitted with 6-piston brakes and fully independent control-arm suspension.

New features for 2008 include a standard Sports mode for all Cayenne engines; standard power rear liftgate; the availability of 21-inch wheels; a rail-mounted cargo management system; and XM satellite radio. Second-generation Cayennes also can be equipped with Porsche Dynamic Chassis Control that features so-called active anti-roll bars that almost completely offset body roll in turns, Porsche says, improving handling, comfort, and safety on road while also providing enhanced traction off-pavement. Other new features include headlamps that turn to provide a better view through curves, trailer stability control for towing, and ABS that works on- or off-pavement.

Each of the four Cayenne models for 2008 is equipped with a unique engine. The standard model, the Cayenne, is powered by a 3.6-liter V-6 engine that pumps out 290 hp, enough to propel the sport utility from a standing start to 60 mph in some 7.5 seconds, the automaker claims. The Porsche Cayenne S model draws on a 4.8-liter V-8 engine that generates 385 hp, good for a similar sprint in less than 6.5 seconds, and yet it also achieves ultra low-emission vehicle status. New for 2008, the Cayenne GTS offers a V-8 engine with 405 hp pulling it to 60 mph in just over 6 seconds. Finally, the Porsche Cayenne Turbo offers a twin-turbocharged version of the 4.8-liter V-8 engine pumping out 500 hp and propelling the Porsche of SUVs to 60 mph in less than 5 seconds, and on to a top speed of more than 170 mph. All Cayenne models share a similar 6-speed Tiptronic S automatic transmission (with the exception of slightly different final drive ratios in each model). The Cayenne and Cayenne GTS are both available with a 6-speed manual transmission. Porsche covers all 2008 Cayenne models with a 4-year/50,000-mile warranty.

Standard safety features on every 2008 Porsche Cayenne include six air bags: dual front, dual side, and dual curtain. In addition, all Cayenne models are equipped with standard Porsche Stability Management including pre-loading of the braking system, ABS, and a new Trailer Stability Control. Safety features are enhanced for 2008 with a new rollover sensor that triggers belt latch tensioners and side curtain air bags to reduce the risk of injury for all occupants in a rollover. The Porsche Cayenne has not been crash tested by the National Highway Traffic Safety Administration (NHTSA) or the Insurance Institute for Highway Safety (IIHS).

All 2008 Porsche Cayenne models feature engines with direct fuel injection. This technology highly pressurizes the fuel before precisely injecting it directly into the combustion chamber. With direct fuel injection, the fuel delivery and injection timing are electronically managed based on the load of the engine. This optimizes fuel delivery allowing higher compression ratios and permitting the engine to run in an ultra-lean mode under many operating conditions. All of this adds up to combustion that is more efficient, the maker claims, resulting in increased power, better fuel economy, and lower emissions.
