Even in the electrified version, a Mercedes-AMG will not go quietly: The first plug-in hybrid from the Daimler Performance company focuses on the classic V8: the four-door GT 63 SE Performance relies on an independent technical layout and uses it E-drive primarily as a performance booster.
As suspiciously as the fan community had expected the first hybrid AMG, it should now be relieved. Even in the PHEV variant, the GT 4-door does not become an economical quiet stepper. This is ensured by the 4.0-liter twin-turbo eight-cylinder with 639 hp, which is flanked by a 150 kW / 204 hp electric motor. In contrast to the more civil Mercedes models, the latter is not housed in the gearbox, but sits directly on the rear axle, in a package with a two-speed gearbox and an electronic limited-slip differential.
It draws its energy supply from a 6.1 kWh battery designed for performance rather than energy density, which allows an electric range of just 12 kilometers. The AC charging power is low at 3.7 kW, and there is no quick charging connection for direct current.
The plug-in hybrid is therefore hardly suitable as an emission-free drive for short stages. Instead, the electric component should ensure superior driving performance. The system provides a total of 620 kW / 843 PS and up to 1470 Nm. The combustion engine directs its power to both axles via the classic all-wheel drive mechanism, while the electric motor also drives the rear wheels. The sedan sprints to 100 km / h in 2.9 seconds, with a maximum of 316 km / h. The manufacturer specifies consumption at 8.6 liters and CO2 emissions at 196 grams per kilometer. Both values are significantly higher than for classic plug-in hybrids with a larger electric center of gravity, and are low compared to the conventional variants of the GT 4-door – the pure V8 models are above 12 liters.
In addition to acting as a horsepower booster when starting and accelerating, the AMG’s electric motor also serves to regenerate braking force. There are four recuperation levels to choose from: from almost zero to one-pedal mode. The most powerful Mercedes-AMG to date is likely to hit the market next year. Visually, it differs only marginally from its conventionally powered siblings.
The prices will be over 200,000 euros. The GT 63 SE Performance is currently the most powerful AMG – until Project One celebrates its market launch. (SPX)
