2014 Audi RS5 vs 2014 Mercedes-Benz C63 507 Coupe

February 28, 2014

The 507 Coupe is the last iteration of the W204 C63. With the exception of the very limited-run Black Series, it’s the best C63 that AMG has ever done. Under its hood sits a hand-built, 6.2-liter naturally aspirated V-8 good for 507 horsepower. What more do you want? Perhaps something more high-tech, and that’s where the Audi RS5 comes in. The sexy coupe from Quattro GmbH in Neckarsulm features a 4.2-liter V-8 that spits out 450 hp. That¹s less power than the 507 Coupe makes, true, but the Audi also features AWD, a dual-clutch transmission, bigger wheels and tires, plus a trick torque-vectoring rear differential. Which one is quicker? Which one is more fun to drive? Which one is best? Watch and find out!
