This competition boils down to raw American muscle against a precision German missile.
There's absolutely nothing bad to say about either of these two cars. The SRT Viper and Mercedes-Benz SLS AMG Black Series each have more than 600 horsepower and are designed to be driven hard. They aren't meant for simple cruising around town as anything like that would simply be a waste of their many talents. And one of those talents is outright performance, especially on the track. One is a product of fine German engineering while the other represents raw American performance.
Both are front-engined, rear-drive, large hooded track animals that were created for one purpose alone: to absolutely obliterate track records. So which one is better? Motor Trend's Jonny Lieberman gets behind the wheel of both to answer that very question in this latest head-to-head competition.
