Porsche has joined other automakers and announced plans to build a Hybrid version of its Cayenne SUV. Production of the Cayenne Hybrid will combine a gasoline engine with electric traction motor(s). Rumors that Porsche have discussed partnering with Volkswagen to build the powertrain are unconfirmed. This would not be surprising though as the Cayenne has a sibling in the Volkswagen Touareg. The two companies have a long and friendly history with the Porsche family (many of whom are board members of Porsche) currently moving to increase their stake of Volkswagen ownership. The former head of Volkswagen Group, Dr. Piëch owns a significant share of Porsche, roughly 13% and happens to be grandson of Ferdinand Porsche.
The second generation Cayenne Hybrid is expected to debut at the along with its conventionally powered siblings at the 2010 Geneva Motor Show. However, that being said, sales for the hybrid model starts later in the fall. The Cayenne S Hybrid makes use of a supercharged 333 PS (245 kW / 328 hp) 3.0-liter V6 engine and a 34 kW electric motor, to boost output to 380 PS (279 kW / 375 hp) and up to 580 Nm (428 lb-ft) of torque at 1,000 rpm. The hybrid is capable of short all-electric drives at speeds up to 40mph (64 km/h). Fuel economy was not revealed, though it produces just 193 grams of CO2 per kilometer. This makes the Cayenne S Hybrid the cleanest Porsche ever.
