In keeping with the Porsche philosophy of evolutionary design, the new Cayenne is seemingly much sleeker in appearance than its predecessor.
Reports from our spy photographer who managed to catch a glimpse of the interior has said it has been heavily influenced by the new Porsche Panamera.
Expect improved interior ergonomics and higher quality materials mimicking that of the Panamera - which can only be a good thing.
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 new Cayenne to boast both a normally aspirated and twin-turbocharged 4.8-litre V8 engine from the Panamera.
The current Volkswagen V6 TDI engine which currently produces 177kW and 550Nm will also make a return with some minor improvements.
Porsche's first Cayenne S Hybrid will appear in the model's current guise as a 2010 model, although its hybrid powertrain should carry over to the 2011 Cayenne virtually unchanged.
The hybrid version will use Audi's supercharged 3.0-litre V6 engine producing 248kW, coupled with a three-phase synchronous electric motor which receives power from a 38 kW 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 - similar to the Audi Q7.
