|A hotter version of the existing Mercedes-AMG GT S will be unveiled shortly. It will be significantly more potent than its 503-hp sibling, but should pack the same 4.0-liter twin-turbo V-8. Some features include four-wheel steering and an industry-first adjustable spool valve shocks. Also appearing are larger rear tires, and as indicated by the teaser, active aerodynamic features.|
The 'new and improved' appears scheduled to debut at the Goodwood Festival of Speed.
