New Porsche Cayenne S hybrid will finally came to market in 2010.

According to the German automaker, the hybridized Cayenne will emit some 20 percent less C02 than comparable combustion engine vehicles with similar power output. Covering a 0-to-100 km/h sprint in just 6.8 seconds, it will earn its ‘S’ designation by delivering V8 performance and four-cylinder efficiency, all while complying with the Ultra Low Emission Vehicle II emission standards.

Cayenne S Hybrid will roll freely at highway speeds without the combustion engine on, greatly minimizing engine emissions and fossil fuel consumption. This differs from current hybrid concepts that deliver benefits mainly in city traffic.
