As a luxury SUV, the Porsche Cayenne E-Hybrid excels on multiple fronts. It's quick and gets decent fuel economy—when it's burning any fossil fuel at all. With a combined output of 462 horsepower from a 335-hp turbocharged 3.0-liter V-6 and a 127-hp electric motor-generator sandwiched between the engine and standard ZF eight-speed automatic transmission, this is the most powerful Cayenne that doesn't wear a Turbo badge. The official zero to 100km/h time is 5.0 seconds, but it feels quicker thanks to the omnipresent torque and the two different motors working in unison conspire to plug any holes in the torque curve. The result is a feeling of boundless and unending power delivery. The Cayenne E-Hybrid upholds the Porsche performance mantra admirably. It's an SUV renowned for its performance potential, yet it's also luxurious and easy to drive.
