The EPA numbers are in.
We've been waiting for the EPA to release the electric range numbers for the Porsche Cayenne E-Hybrid with interest. Porsche uses its hybrid systems more for performance than economy. Still, as the Cayenne is an SUV it's meant to be practical as well as sporty and being able to run short journeys on electric power is a useful feature. Call us crazy, but we like to have our cake and eat it. However, 14 miles on electric power alone is more of a slice of cake. For 2021, though, Porsche has replaced the 14.1-kWh hour battery with a 17.9-kWh unit, and that has boosted its base model's electric driving range to 17 miles.
That's just 3 miles further, but if your daily commute is under 17 miles, that's money saved for more fun trips. The base Cayenne E-Hybrid comes with a turbocharged 3.0-liter V6 coupled to a 134-hp electric motor, so there's plenty of fun to be had with the 455 hp and 516 lb-ft of torque that's delivered to all four wheels. Its total range bumps up 10-miles to 430 miles on a full tank with an estimated economy of 46 MPGe. With the battery depleted, though, the Cayenne E-Hybrid only manages 21 mpg combined.
The Cayenne E-Hybrid Turbo S is a different beast and matches a turbocharged 4.0-liter V8 to the electric drive system. The electric range for 2021 is 15 miles, a gain of three miles over the 2020 model. MPGe is rated at 42, but the gas-only mpg rating stays at 19 mpg. On the plus side, the Cayenne E-Hybrid Turbo S brings a potent 670 hp and 663 lb-ft to the table and will sprint from zero to 60 mph in just 3.6 seconds, while the base model will tackle the same run at 4.7 seconds with the Sport Chrono Package.
