Naming schemes aside, the upcoming top-of-the-line AMG GT is naturally expected to pack more power than existing versions. But it's also tipped to get a four-wheel steering system to improve cornering and high-speed stability, similar to those featured on the Porsche 911 GT3 and Ferrari F12 TdF. A new type of adjustable spool-valve shocks are also said to be in the works, along with active aerodynamic elements. Expect upgraded rolling stock, brakes, and interior to come as part of the package when it debuts in about a year from now.
MT also reports that AMG is also already working on a new E63 based on the forthcoming W213-generation E-Class. The new super-sedan is expected to shed weight by replacing the old 5.5-liter twin-turbo V8 with the newer, more compact 4.0. It's also tipped to get a new nine-speed dual-clutch transmission and a more flexible all-wheel-drive system to replace the fixed 33/67 front-rear torque split on the current model.
