Mercedes-AMG appears to be readying a plug-in hybrid GT four-door range-topper, potentially packing around 600kW.
As it takes off into the distance, the car doesn't make an angry V8 sound – instead, there's the distinct hum of an electric motor, before the camera cuts to a graphic reading "THE FUTURE OF PERFORMANCE".
Despite the EV noises, the AMG 73 four-door still has four chunky exhaust pipes, suggesting it's not a pure-electric vehicle.
Although details about the AMG GT flagship are hard to come by, but the 2017 concept preceding the production GT four-door offers a few clues.
The show car blended a 4.0-litre turbocharged V8 engine with an electric motor for a combined power output of "up to 600kW", and a 100km/h sprint time of less than three seconds.
Drive was sent to all four wheels through a variable 4Matic+ all-wheel drive system with torque vectoring – real torque vectoring, with electric motors on the rear axle allowing for proper 'positive' inputs, rather than 'negative' brake-based assistance.
A release date for the GT73 hasn't been confirmed, but the 2020 Geneva motor show seems likely at this point.
