Porsche Cayenne Engines

Sales for the Porsche Cayenne began in North America in 2003. There are several Porsche Cayenne engines for sale available, depending on the level of trim. The base engine for the first generation Cayenne was a 3.2 liter, naturally aspirated V6 with 240 hp. The Cayenne S and GTS were equipped with 400 hp V8s displacing 4.8 liters. Turbo and Turbo S variants were also produced for this first generation. The Turbo Cayenne had 490 hp on tap while the engine on the Turbo S had 540 hp.

There are diesel-equipped Cayennes being produced for other markets but none are sold in North America. The Cayenne Diesel is equipped with a 3-liter V6 engine producing 240 hp. This diesel is sourced from Volkswagen, which is their V6 TDI engine. During this period a limited edition Porsche Cayenne S Transsyberia was also produced, equipped with the same 4.8 liter V8 found on the Cayenne S and GTS. It was tuned to be able to run on 25 percent ethanol and gasoline, giving it a 15% improvement in fuel consumption. In this state of tune, this V8 4.8 liter Porsche Cayenne engine produced 385 hp.

The second generation Porsche Cayennes were introduced in the first quarter of 2010. The base Cayenne has a 3.6-liter V6 engine, naturally aspirated. As with all Porsche Cayenne engines for this generation, it is equipped with Direct Fuel Injection (DFI), as well as having variable-valve timing for the intake and exhaust cams. Output is 300 hp at 6300 rpm with the maximum torque of 295 lb.-ft. being produced at 3000 rpm.

This second generation of the Porsche Cayenne will share its V8 engines with the Porsche’s luxury car offering, the Panamera. Thus, the Cayenne S will have the same 400 hp 4.8 liter V8 as that found in the Panamera S. Torque firgures for this engine are 369 ft. lb at 3500 rpm. The Cayenne Turbo is equipped with a twin-turbo V8 producing 500 horsepower. To produce that lofty output, the Cayenne Turbo will be be equipped Direct Fuel Injection (DFI), VarioCam Plus and an intercooler. A torque rating of 516 lb.-ft. between 2250 and 4500 rpm is claimed . As with the first generation Cayenne, there is a 240 hp V6 diesel being produced but these will not be made available for the North American market. It is interesting to note that the 2nd generation Cayenne is lighter by about 250 kg over the previous generation. This is the result of extensive use of aluminum for the construction of the body. Because of the lighter weight, fuel efficiency has been improved across the board.

The latest powertrain option for the 2nd gen Porsche Cayenne S Hybrid is also the most technologically interesting. The Cayenne S Hybrid will have a 330 hp combustion engine (a 3-liter supercharged V6) plus a 47 hp electric motor. Combined, the horsepower rating for this powertrain combo is 380 hp with total system torque of 580 Nm. The electric motor is situated between the gasoline engine and the transmission, where it also acts as the alternator and starter. A decoupler, in conjunction with the engine management system, acts to engage and disengage the engine depending on the power needs of the vehicle. 0-100 times for the Cayenne S Hybrid are very close to its siblings, at 6.5 seconds plus, a top speed to 240 km/h.

All Porsche Cayenne engines are equipped with Direct Fuel Injection (DFI) to achieve significant increases in specific power and torque, as well as obtaining better fuel economy and lower emissions.
