600kW Mercedes-AMG GT 73e teased

Mercedes-AMG has given the world its first glimpse of its plug-in hybrid GT 4-Door Coupe that's set to school the Porsche Panamera Turbo S E-Hybrid when it comes to performance.

Expected to carry the Mercedes-AMG GT 73e moniker, the German car-maker's performance division has already detailed its advanced electrified powertrain and revealed that when the new model goes on sale late this year it will produce an incredible 600kW of power and a mighty 1000Nm of torque.

Blending the current GT 63’s M177 4.0-litre twin-turbo V8, the even more powerful GT 73e gets AMG’s latest ‘P3’ E-Performance plug-in hybrid powertrain.

Like in the smaller Mercedes-AMG C 63e, the GT 73e is set to package a two-speed transmission and electronically-controlled limited-slip differential, plus a battery that slots in underneath the boot floor.

Providing an optimum weight distribution, the powerful electric motor can punch out as much as 150kW/320Nm for up to 10 seconds.

That, says AMG, will help provide the big AMG GT with a sub-3.0sec sprint to 100km/h. Top speed has not yet been confirmed but it’s thought to be in excess of 330km/h.

Like the C 63e, the 2021 Mercedes-AMG GT 73e will use a nine-speed AMG Speedshift MCT 9G transmission and 4MATIC variable all-wheel drive that can shuffle 100 per cent of torque to either axle.

Torque vectoring across the axle will also be possible, while the front axle is capable of being decoupled for rear-drive only, providing an opportunity for AMG engineers to introduce a drift mode.

Feeding current to the electric motor to provide a limited pure-electric range at speeds up to 140km/h will be a 6.1kWh lithium-ion battery that draws from tech developed by the Mercedes-AMG Formula 1 team.

Launch timing is still to be confirmed, but the 2021 Mercedes-AMG GT 73e is set to land before the end of the year with pricing likely to match the plug-in Porsche Panamera Turbo S E-Hybrid at about $420,000.
