Launching a 4,795-pound SUV to 60 miles per hour in 3.7 seconds is no small feat. The Cayenne’s twin-turbocharged, 4.0-liter V8 delivers 567 pound-feet of torque from just 1,960 rpm, and the rush of power is unrelenting. The eight-speed Tiptronic automatic transmission shifts with a quickness that’ll fool you into thinking it’s a dual-clutch unit.
