The GT Concept is AMG’s star turn at the Geneva Motor Show which opens today (March 7th). It’s not just a show pony but instead the precursor of an all-new and entirely AMG-developed second model line for the three-pointed star’s go-faster division, intended as a stand-alone AMG without any cooking Mercedes versions.
It certainly promises to go faster, as it will have to if it is to take on its natural rival in the shape of another of Geneva’s show stars, the Porsche Panamera Sport Turismo. AMG is promising that in its most powerful form the new car, rumoured to be called GT4, can boast 600kW (that’s 804bhp). Power is courtesy of the familiar 4.0-litre bi-turbo V8 and a single electric motor working solely on the rear axle to act as a performance booster. The new concept is all-wheel drive with torque vectoring for each wheel and carbon ceramic brakes.
The drivetrain, inspired by the F1 car’s and similarly badged EQ Power+, aims to take the big new sedan from 0-62mph in less than 3.0 seconds. It is said to use the “operating strategy” of the F1 car in that, like the F1 car and coming hypercar, the batteries are kept charged by the V8 and brake recuperation so they are always in a position to unleash an occasional KERS-style blast of extra power when needed. Typically for a hybrid, there are three driving modes, short-distance electric-only, V8 only, or with both petrol and battery power working together for maximum thrust.
AMG says the moniker "EQ Power+" will be the badge on all its future performance hybrids, each tailored to different sectors of the market and all with what the firm says will be “incomparable outputs”.
