Porsche has introduced the most-powerful Cayenne models ever, and they’re hybrids. The standard and coupe variants of the new 2020 Porsche Cayenne Turbo S E-Hybrid come fitted with a 4.0L twin-turbo V8 engine (541 hp) working in conjunction with an electric motor (134 hp), for a combined output of 670 hp and 663 lb-ft of torque.
This kind of punch and quick torque under the hood gives the new Cayenne versions a 0-100 km/h acceleration time of just 3.8 seconds. Electronically limited top speed for the models is a hair under 295 km/h. On a full charge, all-electric range is around 40 km.
Also announced by Porsche today is the 2020 Cayenne E-Hybrid Coupe, which “settles” for a 3.0L turbocharged V6 engine working with the same electric motor as the two Turbo S models; in its case, combined output is 455 hp and 516 lb-ft of torque. The powertrain delivers 0-100 km/h acceleration in 5.0 seconds. All-electric range for this version is set at 43 km, according to European testing standards.
The Cayenne plug-in hybrids work from a 14.1 kWh battery that has 30% more energy capacity than the previous system used by Porsche. That battery can be recharged to full in 2.4 hours with the 7.2 kW charger included standard; plugged into a 230-volt outlet, charging time is 6 hours. In case you’re wondering, when in electric-only mode the Cayenne has a top speed of 135 km/h.
