The Bentley Mulsanne is a road-going yacht that's much more about comfortable cruising than outright speed. But more power is always nice. So this version has an upgraded 530 horsepower V8 engine -- 25 more than the "base" model -- and an amazing 811 foot pounds of weight-pulling torque. That's enough to get this car from a stop to 60 miles per hour in 4.8 seconds, an impressive feat for a car roughly as big as a full-sized SUV.
