Spied: 2013 Mercedes-Benz S63 AMG
The big bad Benz still testing under a blanket of heavy camouflage

Caught undergoing testing near the Nürburgring by our Teamspeed spies, the heavily camouflaged prototype of the future S63 AMG is featuring a larger air intake, a high performance braking system and AMG wheels. It remains unknown yet what engine will be used, but the most likely option is a 5.5 litre V8 turbo for the S63 and a bi-turbo variant of that very engine for the S65 – then delivering around 630 hp. The current 6.2-litre engine used for the 63 AMG models of the past will slowly die. Both variants should be connected to seven-speed Speedshift MCT transmissions, which will ensure this is really a fast flagship. Stay tuned for more!

 

Nice, I'm really curious what this thing is gonna look like!

 

The tail lights are definitely interesting. The over all design is intriguing.

 

Nice black porsche 997 turbo wheels.
