With a lighter, torquier, and slightly more efficient version of the VW Group diesel V-6 found in other crossovers from its brands, the 2013 Porsche Cayenne Diesel is arguably the best of the bunch--though the argument is swayed perhaps more forcefully considering the Cayenne's level of refinement, style, and ability.

Under the hood sits a 240-horsepower, 406 pound-foot 3.0-liter turbodiesel V-6 engine, mated to an eight-speed automatic transmission and all-wheel drive. That big torque figure puts the diesel ahead of even the much more powerful Cayenne S, and should make for enjoyable dynamics, if not quite as heady a rush at the top end of the tachometer.
