As the six-cylinder Cayenne Diesel is finally introduced to the US market,
Porsche has unveiled a new, more powerful diesel-powered version of the popular luxury SUV. Packing a 4.2-liter turbodiesel V8, the new Cayenne S Diesel offers up a solid 382 horsepower but a monstrous 626 lb-ft of torque. That's a significant jump on the existing Cayenne Diesel's numbers: 142 hp and 220 lb-ft, to be precise, translating to a 0-62 mph time of 5.7 seconds and a 157 mph top speed.
