The Porsche Cayenne Hybrid is about 400 pounds lighter than its older sibling which ruled between 2003 and 2010. It also boasts of better fuel mileage.

Unlike the Volkswagen Touareg Hybrid which shares the platform with the Cayenne, Porsche decides to keep the V-8 options for its engines. The entry level Cayenne will have a V-6 3.6L that can give out 300 horsepower coupled with a triptonic automatic gearbox.

The S Hybrid is packed with 333 hp drawn from supercharged 3.0L V6 coupled with a 47 hp electric motor. Combine the two and you will have an impressive 427 ft lb of torque at 1,000 rpm. Talk about power which can make the S Hybrid king of stoplight racing.

The top of the line Cayenne S will sport the V8. One can give out 400 hp while the Cayenne Turbo can output 500 hp. Though more powerful, these two versions are 23% more fuel efficient than the older Cayenne.

According to Porsche the Cayenne S Hybrid can also shut down its engine while “sailing” at 97 mph unlike other hybrids which can only switch off their engines at very low speed. The S Hybrid version will only emit 193 g/km of carbon dioxide while having a fuel mileage of 28.3 mpg. The Cayenne S Hybrid is the most fuel efficient model in Porsche’s line up.

The Cayenne S Hybrid and the base V6 model will hit dealerships this fall. The V8s will reach the US shore by July this year.

The car manufacturer is planning to apply a parallel electric motor that is capable of revving the SUV to speed the road up to an amazing 86 miles per hour with just its engine, without the aid of stepping onto the gasoline. Now that is a lot faster than the forthcoming third-generation Ford Fusion Hybrid and Toyota Prius. These two leads the rest of the known speedometer giants that can be driven with an electric power alone.

But as to compare with those models, the Cayenne S Hybrid cannot actually speed up to that rate without the use of the two engines. But, don’t fret, for this makes Cayenne S Hybrid an advantage in some certain situations, like in jam-packed traffic.

Porsche also announced that the car model will be able to emit 20 percent less carbon dioxide than other vehicles and will be able to comply with the ULEV-II emissions standards. The flashy output is owed from the parallel hybrid car make-up. The direct injection 3.0 liter V6 that is supercharged is from Audi, and it actually gives off 333 horsepower and 324 lb-ft of torque. The engine system is also geared up with a 154-pound nickel-metal-hydride battery that is found kept in the spare tire well.

According to Porsche, a hybrid type of the Panamera will also be shown after the Cayenne S Hybrid’s launch.
