2023 Mercedes-AMG GT63 S E Efficiency plug-in hybrid debuts with 831 HP

AMG’s first PHEV is a hell of a factor.


Mercedes-AMG is lastly displaying off its first plug-in hybrid, and it’s a doozy. The brand new GT63 S E Efficiency takes System 1 expertise and brings it to the road, melding AMG’s present twin-turbo V8 with an electrical motor and a complicated battery pack, all stuffed into the prevailing GT 4-Door Coupe physique. The result’s AMG’s strongest manufacturing car ever, and an indication of what’s to come back from the model.

The dual-turbo, 4.0-liter V8 places out the identical 630 horsepower and 664 pound-feet of torque as within the present GT63 S, although it now options an built-in 48-volt starter-generator system. Positioned on the rear axle is a single electrical motor placing out 201 hp and 236 lb-ft that has its personal two-speed gearbox; as it really works instantly on the rear axle it gives faster responses and acceleration. There’s an electronically managed limited-slip differential for higher grip and energy supply in corners, and electrical energy might be despatched to the entrance wheels as required. AMG additionally overhauled the usual air suspension setup and the GT’s stability management system.

There’s quite a bit happening beneath the pores and skin.


The light-weight 6.1-kWh lithium-ion battery pack lies simply above the EV motor, and growth of the battery was influenced by the one utilized in Mercedes’ F1 automotive — the AMG workforce in Affalterbach, Germany, labored intently with the F1 engine store within the UK on the system’s engineering. The 400-volt battery weighs simply 196 kilos and has double the facility density of conventional batteries, because of a world-first direct-cooling system that all the time retains the battery on the optimum working temperature.

All that provides as much as a whopping whole output of 831 hp and 1,033 lb-ft, with Mercedes saying the GT63 PHEV will hit 60 mph in 2.9 seconds, 125 mph in beneath 10 seconds, and attain a high pace of 196 mph. The place the GT63 S E Efficiency is missing is electrical vary. AMG says it’s going to solely do about seven miles on electrical energy alone, however that’s on objective. The powertrain was designed for “quick energy supply” as an alternative of an extended vary, so efficiency is the true aim right here. It’ll hit 80 mph on electrical energy, and there’s an AMG-specific sound that’s performed outdoors the automotive at speeds as much as 18 mph, fading out when the automotive reaches 31 mph. The cost port is situated on the rear bumper, and whereas AMG doesn’t give any charging specs it’s going to use a 3.7-kW on-board AC charger.

The cost port is on the rear bumper.


There are seven drive modes in whole, with the brand new Electrical mode becoming a member of Consolation, Sport, Sport Plus, Race, Slippery (for moist circumstances) and the configurable Particular person mode. Within the EV mode all-wheel drive continues to be all the time accessible because of the electrical motor’s mechanical connection to the drivetrain, and when the battery has been depleted the automotive robotically switches to Consolation mode. In Consolation the automotive deploys electrical driving when it’s most helpful, like at low speeds within the metropolis. Delve into the Sport and Race modes and the V8 wakes up, with the electrical motor offering a efficiency increase. The automotive usually begins up silently in electrical mode, however a particular sound “typical of AMG” is performed by the inside’s audio system to let the driving force know the automotive is prepared.

The GT63 S E Efficiency has 4 ranges of regenerative braking which are managed by a button on the steering wheel, with the bottom stage of regen principally unnoticeable to the driving force, whereas the best stage gives one-pedal driving like with a full EV. When the automotive is within the Race drive mode, the regen system is robotically set to Degree 1, which gives the “most reproducible car habits” on-track. The E Efficiency additionally comes customary with large carbon-ceramic brakes, with 17-inch discs and six-piston calipers up entrance, and 15-inch discs and single-piston calipers on the rear.

The inside is principally similar to the common GT 4-Door.


We already noticed the up to date six-cylinder GT 4-Door fashions earlier this yr, and the V8 PHEV sticks near that very same method. The entrance air intakes are bigger and have new vanes, there’s a bunch of recent paint choices together with 4 matte finishes, and Mercedes added extra exterior look packages. Hybrid-specific particulars are restricted to fluted exhaust suggestions and pink badges. The E Efficiency additionally has a bunch of distinctive information pages within the MBUX infotainment system, a brand new steering wheel design and extra colour and trim choices for the inside.

Mercedes isn’t saying something about how a lot the GT63 S E Efficiency will value, however with the conventional GT63 S already beginning at $162,950, don’t be shocked if the PHEV crests the $200,000 mark. Full US specs will likely be introduced nearer to the E Efficiency’s on-sale date for the 2023 mannequin yr.
