Mercedes released recently the first teaser video of the future generation 2014 S63 AMG, which is expected to go on sale next year. The 2014 Mercedes S63 AMG is going to be powered by a 5.5-liter twin-turbo V8 engine, which has an output of just under 560 hp. Mercedes is expected to offer a more powerful version of the new S36 AMG (2014), which is probably going to develop 858 hp. The 2014 S63 AMG's engine will be mated to the 7-speed Speedshift transmission and possibly, an all-wheel-drive system.
