Porsche introduced its all-new, third-generation Cayenne crossover late last year as a 2019 model. Its new chiseled appearance complemented a more luxurious and technically innovative 5-passenger crossover, which told shoppers that it had moved upscale. Yet, until now, Porsche had only announced a pair of turbocharged engines for the mid-size vehicle — a choice between traditional V6 and V8 power. Last week, however, the German automaker added a new model that promises to alter the way people look at fuel-efficient crossovers: the all-new 2019 Porsche Cayenne E-Hybrid is a gasoline-electric variant tuned for performance.

Innovative Hybrid Packaging Delivers Power and Efficiency

The Cayenne E-Hybrid boasts a very unique hybrid “sandwich” powerplant under its hood. At the top is a traditional combustion engine (a turbocharged 3.0-liter V6 rated at 455 horsepower and 516 lb-ft of torque). At the bottom is Porsche’s “Tiptronic S” torque converter 8-speed gearbox. The filling in the middle — literally sandwiched between the engine and the gearbox — is an electric motor (rated at 134 horsepower and 295 lb-ft of torque). Included in the hybrid package is an electromechanically-actuated separating clutch, which allows the transmission to uncouple from the driven wheels at will. This arrangement maximizes efficiency as it virtually eliminates the considerable drag of a powertrain during coasting. Reducing unnecessary componentry, there is no traditional starter or alternator — the electric motor accomplishes both tasks naturally.

Combining the power of the combustion engine and electric motor, the Cayenne E-Hybrid’s total system output is 455 hp and 516 lb-ft of torque – the 0-to-60 mile-per-hour sprint is accomplished in just 4.7 seconds with a top track speed of 157 mph. Those figures best many dedicated sports cars.
