Want an American version of the full-size luxury performance sedan? How about the 440 hp, Northstar V-8 powered Cadillac STS-V? It's got every luxo amenity in the business and a top speed of 160+ mph to boot! And if you need to stop, it can put the whoa on from 60 mph in approx ~120 ft. 'Ring lap times of 8 min 30 sec (that's really fast-158 mph down the straightaway!).
