Porsche's upcoming 2011 Cayenne SUV has once again been spotted undergoing testing in Germany.
The exterior follows in Porsche's philosophy of evolutionary design but from the spy pictures, it appears clear that the new model features a much sleeker appearance than the current Cayenne.
One of our shooters got a glimpse of the interior and reports that the cabin is heavily influenced by the new Porsche Panamera, so expect the 2011 Cayenne to have a vastly improved interior that uses higher quality materials.
While we can't say for sure what model is being tested in these shots, the new Cayenne should boast a variety of petrol, diesel and hybrid engines.
On the petrol side, we can expect the 2011 Cayenne S to come with the Panamera's 4.8-litre V8 engine that develops 298kW while the top-of-the-line Cayenne Turbo should be powered by the 4.8-litre twin-turbo V8 engine from the Panamera Turbo that cranks out 373kW.
In diesel models, expect the current Volkswagen V6 TDI engine which produces 179kW and 550Nm of torque to carry over to the next generation with some minor improvements.
Considering that Porsche's first Cayenne S hybrid will appear as a 2010 model, its hybrid powertrain should carry over to the 2011 Cayenne virtually unchanged.
Power for the hybrid comes from Audi's supercharged 3.0-litre V6 engine that produces 248kW, and it is connected to a three-phase synchronous electric motor which receives power from a 38kW NiMH battery that resides in the spare tire well.
The new Cayenne is also supposed to adopt a more street focused setup, which means some of the current model's bulky off-road equipment could be dropped in order to make the new one more Porsche-like.
Audi took a similar approach when they introduced the Q7 and that model has received rave reviews for offering a decent driving experience despite its large size.
