Sure,the 2015 Mercedes-Benz S63 AMG 4MATIC Coupe has plenty of appeal when you consider it in terms of looks alone — with its gorgeous styling highly reminiscent of the equally-impressive Concept S-Class Coupe. But perhaps more appealing is what's hidden beneath its aggressively-styled body: a hand-built bi-turbo 5.5-liter V8 engine, capable of producing 577 horsepower and a staggering 664 pound-feet of torque. But, we're pleased to say, that's not all. It's packed with electronic goodies made to improve the driving experience while making it safer (stuff like crash-preventing brakes, active steering, and adaptive air suspension). Pair that with ceramic brakes, lightweight construction, all-wheel drive, a seven-speed transmission, and what you get is one incredible piece of engineering that's also safe and comfortable to drive. That sounds like a win-win.
