The long-awaited Mercedes-AMG GT 63 E Performance has just been unveiled as the most powerful production vehicle from the car manufacturer (other than the F1-powered Project One). Found at the heart of the super sedan is a 4.0-liter twin-turbocharged V8 engine that works alongside an electric motor positioned at the rear axle. This motor is integrated with an electrically shifted two-speed transmission and an electronically controlled limited-slip rear differential. All up, the GT 63 E Performance pumps out 831 hp and more than 1,400 Nm of torque. The car also features a belt-driven starter-generator with 14 hp.
Mercedes-AMG quotes a 0-100 km/h time of just 2.9 seconds and a top speed of 316 km/h. The car also returns a frugal 27 mpg (8.6 l/100 km). Providing the electric motor with its juice is a 6.1-kWh high-performance battery pack that weighs just 89 kg. It has an onboard 3.7 kW AC charger and according to AMG has been designed for fast power delivery. As such, the GT 63 E Performance only has 12 km of all-electric range.
A key feature of the battery pack is the fact that it uses a high-tech coolant with non-conductive liquid that flows around all 560 cells and cools them individually. Roughly 14 liters of coolant continually flows through the battery pack to keep it at the optimal temperature of 45 degrees Celsius, regardless of how often it is charged or discharged.
No less than seven AMG Dynamic Select driving modes are available: Electric, Comfort, Sport, Sport+, Race, Slippery, and Individual. Most of these speak for themselves, although the Slippery mode is particularly interesting as it reduces power and delivers a flat torque curve to help in slippery conditions. All-electric driving and regenerative braking adjustments are also disabled. Ordinarily, there are four levels of regeneration that are available.
All Mercedes-AMG GT 63 E Performance models come standard with AMG Ride Control+ multi-chamber air suspension with automatic level control and adaptive, electronically-controlled adjustable damping. The car is also outfitted with carbon-ceramic brakes with 420 mm front discs and six-piston calipers operating alongside 380 mm rear discs with single-piston calipers.
Few styling modifications have been made to the car. In fact, the E Performance badges and plug flap on the rear fascia are the most obvious points of difference from a standard GT 63 4-Door. Admittedly, AMG has also designed new 20- and 21-inch light-alloy wheels, each in two color variants. Customers can also opt for the AMG Night Package II or a combination of the Night Package and Carbon Package to make the sedan stand out further. Some minor interior changes have also been made, including AMG hybrid-specific displays and functions. This includes graphics on the infotainment display that visualize the power flow of the entire drive system. Rear-seat passengers also receive information on the energy flow.
