It looks like Mercedes is going after the Porsche Panamera with the throttle wide open, as the latest reports say that the upcoming GT4 four-door model will offer 800hp in its top version.
Base models will be powered by the twin-turbo 4.0-liter V8 which will be tuned for over 600hp but Mercedes also plans a hybrid powertrain inspired by Formula 1.
This version will continue using the 4.0-liter V8 unit, only now it will be helped by an electric motor in order to produce 805hp and enable the upcoming AMG GT4 to accelerate from 0-62mph in under 3 seconds, Autocar reports.
Power will be transmitted in all four wheels, using the same all-wheel drive system that debuted with the E63 model, with the range-topping 805hp version expected for launch in 2019.
Numbers like these will put the hybrid GT4 way ahead of the Porsche Panamera Turbo S E-Hybrid, which is right now the closest thing to a rival, with its 671hp and 0-62 in 3.4 seconds.
Mercedes is planning to launch the less-insane 600hp AMG GT4 in September 2018, with prototypes already spotted on several occasions being tested at the Nurburgring.
