This is the new Mercedes-AMG GT 63 S E Performance – the first hybrid version of Mercedes’ luxurious four-door coupe and, with 843hp, the most powerful car AMG has ever built.
This is the new Mercedes-AMG GT 4-door 63 S E Performance. Forget the impractically long name for a second, because this ludicrous 843hp hybrid is the most powerful AMG road car of all time.
It looks like the Audi RS7, Porsche Panamera and the BMW M8 Gran Coupe Competition have plenty of sleepless nights ahead…
The new GT 4-door hybrid looks very similar to the standard GT 63 S. The only real difference at the front is in the new vertical, rather than horizontal, bars within the air intakes under the headlights. Somebody really earnt their designer’s turtle-neck jumper that day, didn’t they?
Ok, so you do get some new 20- or 21-inch alloy wheels, there’s a tiny red ‘E Performance’ badge on each side and a new charging flap in the rear bumper, but these are all small tweaks in the grand scheme of things…
AMG has built a few hybrid cars before – such as the AMG GLE 53 and E53 models – but these are just mild hybrids that use a small motor to give the engine some help when you accelerate.
This new AMG GT 4-door E Performance is a proper full-blown hybrid. It pairs a 639hp twin-turbo 4.0-litre V8 from the normal AMG GT 63 S with a brand-new 204hp electric motor.
Together, this new hybrid system produces 843hp and a colossal 1,470Nm of torque.
The new AMG GT hybrid comes with a 6.1kWh battery that Mercedes says took inspiration from the batteries in its Formula One cars.
Putting the technical talk to one side, this means it’s lighter than most batteries with the same capacity and it has some clever cooling technology that helps it deliver lots of power in a short burst without overheating.
So how much range do you think it has? 25 miles? Maybe 15 miles? Nope – a full charge gives the new GT 4-door hybrid just seven miles of range.
At least it’ll do 80mph in EV-only mode, though, and 7 miles of range is probably enough to get you to a nice quiet back road where you can fire up the twin-turbo V8…
This new E Performance model comes with the same 9-speed multi-clutch gearbox as the standard AMG GT 4-door. However, AMG has added another 2-speed gearbox – just for the electric motor.
If you thought the new 4-door hybrid’s exterior changes were hard to spot, wait until you get inside – it looks almost exactly the same as the regular car.
You get the same sweeping dashboard and raised centre console with buttons laid-out to look like cylinders in a V8 engine. The steering wheel has a new design with some thinner spokes, but that’s the only real change.
The dual-screen infotainment system is mostly the same, too – although it has some new graphics and extra menus that let you control the car’s hybrid system.
Mercedes hasn’t said how much this new car will cost, but you can bet it’ll be even more expensive than a normal AMG GT 4-door – after all, electric motors and fancy F1-inspired batteries don’t come cheap.
The standard AMG GT 63 S will set you back around £140,000, but don’t be surprised if this new hybrid ends up costing more than £160,000.
