Mercedes-AMG is putting the finishing touches on its eagerly awaited AMG GT 4. The Porsche Panamera rival is only the third wholly developed car by AMG, and is expected to take over the mantle from the AMG CLS 63 as the marques sole four-door coupe.
Based on spy shots, it appears the AMG GT 4 will be heavily influenced stylistically by the Mercedes-AMG GT Concept. But under the skin is where things get very interesting.
The initial model is said to feature the same 450kw 4.0-litre bi-turbo V8, nine-speed automatic gearbox and fully variable four-wheel drive system as the AMG E63 S 4Matic, upon which it is largely based. Apart from that, there will be three hybridized versions joining the line-up later, with differing amounts of power, with the first being 500kw, then 550kw and the flagship packing 600kw. All will feature an all-electric range of up to 50kms.
The hybrid drivetrain uses AMG’s 4.0-litre bi-turbo V8 engine, mounted longitudinally up front, in combination with an electric motor sited within the rear axle. The engine can send power to all four wheels, while the motor delivers power exclusively to the rear wheels.
The AMG GT 4’s primary competitor is likely to be Porsche’s Panamera Turbo S E Hybrid which produces 500kw from its hybridized powertrain, and is capable of a 0-100kph sprint in just 3.4 seconds.
The Mercedes-AMG GT 4 is expected to be unveiled at March’s Geneva Motor Show, before going on sale in September 2018.
