New Mercedes-Benz E-class drives itself, sometimes (pictures)

The E63 AMG version gets a twin turbo 5.5-liter V-8, producing 550 horsepower and 531 pound-feet of torque, along with a seven-speed automatic transmission using Mercedes-Benz's SpeedShift technology, which virtually eliminates hesitation or slush during gear changes. An all-wheel-drive system, tuned for performance, comes standard.

Mercedes-Benz also came up with an E63 AMG S model, with power boosted to 577 horsepower and 590 pound-feet of torque.
