The Cayenne's appearance was criticized on the BBC TV series Top Gear. The presenters concluded that whilst the car was well engineered and was a capable off-roader, it was an extremely ugly vehicle.
All 2008 engines feature direct injection. The charge-cooling effect of direct fuel injection permits a higher compression ratio without the risk of detonation, improving horsepower and torque. There are currently 6 engines available in the Cayenne:
- 3.0L 240PS V6 Turbo Diesel from Volkswagen
- 3.6L 290PS (273ft·lbf) VR6 from Volkswagen (Based on the unit offered in the VW & Audi but with modifications made to the intake, exhaust, timing systems and head)
- 4.8L 385hp (283kW) 369ft·lbf (500N·m) V8 (S)
- 4.8L 405hp (298kW) 369ft·lbf (500N·m) V8 (GTS)
- 4.8L 500hp (368kW) 516ft·lbf (700N·m) twin-turbocharged V8 (Turbo)
- 4.8L 550hp (404kW) 553ft·lbf (750N·m) twin-turbocharged V8 (Turbo S)
Cayenne (Base Model)
The Base model is powered by a 3.6-liter VR6 engine producing 290hp (220kW); modifications in the exhaust manifold allow power to peak at 6700 rpm. The Cayenne V6 pricing starts at $45,000, making it the lowest priced Porsche available.
Starting in February 2009, the Base model is also offered with a 3.0-liter V6 Turbo Diesel.
The S is powered by a naturally aspirated 8-cylinder engine with a compression ratio of 12.5:1. A dry-sump lubrication system improves efficiency, while Porsche's VarioCam Plus variable timing extends the power band. The Cayenne S' 4.8-liter V8 produces 385hp (287kW) and 369ft·lbf (500N·m) of torque. Acceleration from 0-62 mph is 6.4 seconds and the top speed is 155 miles per hour.
The GTS is powered with a 405 hp 4.8 liter V8 and features a new sport suspension and 21-inch (530mm) wheels. It slots between the Cayenne S and Cayenne Turbo, is lighter than the Cayenne S, and has an aerodynamic body kit. Its unique feature is a second row of bucket seats instead of the Cayenne's standard bench. The Porsche Cayenne GTS has a 0 to 60mph (97km/h) time of 5.7 seconds. A six-speed manual transmission is also offered.
