Yes, its basic layout is largely the same as that of the S. Both models have four-wheel drive, V-8 power, and a 7700-pound towing capacity. But Porsche went to great pains to address some criticisms of the other models, a major one being that a Porsche–any Porsche–should have fantastic handling and plenty of power. The Cayenne wasn’t lacking in the power department (with the possible exception of the V-6), but even with that, Porsche found a way to pull another 20 horsepower out of the 4.5-liter V-8, bringing the total to 405 for the GTS. (Torque numbers are identical to those of the S, at 369.) The new-for-2008 V-8 uses direct fuel injection, which works with VarioCam Plus valve lift and timing control to provide more power than the previous-gen’s V-8, plus helped the SUV earn an ULEV rating. And unlike the S, the GTS comes standard with a six-speed manual transmission, with which it can reach 60 mph in 5.7 seconds. Our tester, with the six-speed Tiptronic automatic, reached that speed in 6.1 seconds, 1.2 seconds faster than the current-gen V-6-powered Cayenne and 0.8 second faster than the previous S.
