2011 Mercedes-Benz S63 AMG
Sometimes bigger isn’t always better. For 2011, AMG is introducing its own special version of a new Mercedes-Benz V8 engine that produces more power while getting better fuel economy – an astounding feat, considering that increasing either one usually decreases the other. Replacing the normally aspirated 6.3-liter V8 in the $138,875 S63 AMG sedan, the new smaller-displacement 5.5-liter twin-turbo V8 features twin turbochargers, direct fuel injection, start/stop technology and multi-spark ignition and produces 536 horsepower and 590 lb.-ft. of torque.
