The 2010 Porsche Cayenne is offered in six different models--the base V6, the S, the GTS, the Turbo, the Turbo S and the S Hybrid--each offered with a different powertrain. A 290-horsepower, 3.6L V6 comes with the base model, paired with either a standard 6-speed manual or 6-speed Tiptronic S automatic transmission. The S utilizes a 385-horsepower, 4.8L V8, and is available only with Tiptronic S transmission. The GTS squeezes 405 horsepower from the 4.8, with the 6-speed manual as standard and Tiptronic S available. The Turbo and Turbo S make use of the 4.8 as well, but it's fed by twin turbochargers. The Turbo's engine makes 500 horsepower, while the Turbo S churns out 550. The new S Hybrid pairs a 3.0L V6 with a battery-powered electric motor to make a combined 385 horsepower, can run on either on or both of its power sources, and requires no plug-in charging. It also comes with a new 8-speed automatic transmission, and it maximizes mileage by using electric motors to run accessories such as the power steering, air conditioning, brake booster, and transmission oil pump. It's 310 pounds heavier than a standard base-model Cayenne, including the 88-pound "Hybrid Manager" computer, which is said to be one of the most powerful units ever fitted to a motor vehicle.
All Cayenne engines feature direct injection for improvements in both fuel efficiency and power. All V8 models feature VarioCam Plus variable valve timing, which varies intake valve timing and lift, and a variable oil pump for the dry-sump lubrication system that is oriented toward high-performance driving.
The 5-passenger Cayenne offers two spacious rows of seating; the rear seat is split 60/40 and can fold flat to expand the cargo floor for larger items.
The Cayenne adapts to changing road conditions using Porsche Dynamic Chassis Control (PDDC), which utilizes hydraulic pressure to change the stabilizer-bar response depending on the road surface or cornering forces. The system allows both a smooth ride when on or off-road.
All Cayenne models get large disc brakes with 6-piston calipers in front and 4-piston units in back. Turbo S models benefit from especially grippy ceramic composite brakes. The Porsche Stability Management system--including a trailer stability control mode--is standard across the line, as is a power liftgate and "Sport" mode, which changes the engine mapping when engaged for improved throttle response. When properly equipped, the Cayenne can tow over 7,700 pounds.
A limited-edition Transsyberia model is available, inspired by Porsche's successful rally model, combining the 405-hp 4.8L V8 from the GTS with unique exterior styling that includes four new color combinations with contrasting stripes, side mirrors, and wheels. A light bar is available as a no-cost option, and inside, Alcantara sport seats are standard, along with "Transsyberia"-logoed instrumentation and door sills.
The options list for the Cayenne is vast, including everything from an off-road package with skid plates to a trailer-towing package, luxury features such as a heated steering wheel and various distinctive woodgrain interior trims. Base V6 models get 17-inch alloy wheels, while S models upgrade to larger 18-inch wheels. Several different wheel designs are optional, ranging up to flashy 21-inchers, which are standard on Turbo S models.
Big news for the 2010 Porsche Cayenne line is the addition of a new gas/electric hybrid version as well as a limited edition S Transsyberia model. The hybrid is what Porsche calls a "full hybrid," which means it can run on either one of its two power sources independently or together, depending on driving needs. The gas engine is a direct-injected 3.0L Audi V6, which is joined by an electric drive and an 8-speed automatic transmission, and Porsche claims the combination delivers 385 horsepower and 25% better fuel economy than a regular V6-equipped Cayenne. The S Transsyberia model features unique exterior styling, available off-road lights, and four additional colors, as well as the 4.8L 405-horsepower engine from the GTS. The GTS sees the addition of new 21-inch wheels and Porsche's Air Suspension Management, which allows the driver to select between sport and comfort modes. The Turbo S also gets new 21-inch wheels and Air Suspension Management, as well as a new exterior color and several new interior styling options.
The 2010 Porsche Cayenne appeals to people who want a nimble, high-performance SUV that features the kind of driving experience expected of Porsche, combined with the ability to tow a trailer or take on rough terrain.
