The Mercedes-AMG GT 63 S E Performance 4dr Coupe offers a unique driving experience with its hybrid powertrain. When you start the car, you are greeted with a synthesised electric pulse, indicating that the hybrid system is ready. By default, the car operates quietly in electric mode, only engaging the powerful V8 engine when you select the driving mode.
The car is designed to be versatile, with a wide range of operating modes from Comfort and EL (electric) to Sport+, Race, and Drift. However, while the GT 63 S E Performance offers impressive dynamic capabilities, there are some compromises in its finer details.
At low and medium speeds in Comfort mode, you may notice occasional jerkiness from the gearbox and inconsistent throttle response. There is also a noticeable high-frequency noise coming from the rear-mounted electronics, which can be distracting and unexpected in a luxury GT car.
Switching to Sport or Sport+ mode brings out the expected thunderous sound from the V8 engine, especially with the addition of AMG’s sports exhaust. However, the overall sound of the combustion engine lacks the distinctive character you would expect from an AMG super-saloon.
When it comes to performance, the GT 63 S E Performance exceeds expectations. It accelerates from 0 to 60mph in just 2.9 seconds, 0 to 100mph in 6.6 seconds, and completes the standing quarter-mile in 10.9 seconds. It also impresses with its 30-70mph acceleration time of 2.5 seconds. In comparison to the BMW M5 CS, the GT 63 S E Performance sets new benchmarks.
Under full acceleration, the car feels powerful and responsive, with consistent thrust throughout the rev range. However, it is worth noting that the GT 63 S E Performance relies heavily on its combustion engine, which is highly stressed and lacks the free-revving nature of other AMG models.
In the sportier driving modes, the car has an interesting quirk where it reserves a portion of the electric rear axle’s boost as a “push to pass” feature. This extra power is only accessible by pushing the accelerator pedal beyond its kickdown point. While this may make the driver feel like a Formula 1 star, it adds complexity to the driving experience and can be challenging to manage at the limits on a track.
