Mercedes wasn’t the first automaker to stuff a behemoth powerplant into the engine bay of an everyday passenger car. And they certainly won’t be the last. But their skunkworks AMG division has learned a thing or two over the years about transforming your mom’s luxury car into Satan’s drag racer. This Arctic White C63, based on the company’s best selling C-Class luxury car, was found loitering on Spring Street one sunny July afternoon. Although buffs can quickly spot the C63 AMG’s aesthetic tweaks – like a gaping face, wider track, unique 18-inch wheels and AMG body kit all around – the car is a relative sleeper to those who cross its path. But there is nothing ordinary or everyday about a hand-built 6.2-liter V8 that sends 451 HP to the rear wheels and rockets to 60 MPH in 4.3 seconds. C63 competes against similarly intentioned luxury rods from BMW, Audi, Cadillac and Lexus. But with sustainable energy on the drawing board at nearly every major automaker, who knows how long you will be able to buy one of these power mongers. Get ’em while you can people.
