We have a fairly good idea of what the new 2011 Porsche Cayenne look likes, thanks to a couple of official leaks and some revealing spy shots, but in less than two weeks all will finally be revealed as the new SUV makes its debut at the 2010 Geneva Motor Show.
The current-generation Cayenne Diesel achieves a fuel economy of around 25.3 mpg (Combined European) but with a kerb weight almost 400 pounds lighter, the new Cayenne Diesel should achieve significantly better results. The Cayenne S Hybrid, however, will be the most fuel efficient Porsche in the automaker’s lineup, returning a fuel economy of about 28.7 mpg.
The regular gasoline models will include the base Cayenne, powered by a 3.6-liter V-6 model with 300 horsepower, the naturally aspirated 4.8-liter V-8 Cayenne S with 400 horsepower and a range-topping twin-turbocharged 4.8-liter V-8 Cayenne Turbo with 500 horsepower.
This latter model has been seen testing for the first time, captured here by spy photographers whilst being filled up with diesel fuel near a test location in Northern Europe. The new 2011 Porsche Cayenne Diesel will pack the same 240 horsepower 3.0-liter V-6 turbodiesel engine found in the current model but will tuned slightly to produce fewer emissions.
Two more models will eventually join the lineup: the Cayenne S Hybrid, which packs a supercharged 3.0-liter V-6 and electric motor for a combined output of 375 horsepower, and the new Cayenne Diesel.
Sadly, neither the Cayenne Diesel nor Cayenne S Hybrid will be arriving in the U.S. anytime soon.
