The Mercedes-AMG GT Concept bowed in 2017 as a preview of the GT 4-Door Coupe, the striking show car was said to boast a powerful electrified V-8 under the hood. So far, such a powertrain hasn’t taken shape, but it appears that will soon change.
Like other versions of the AMG GT, power will come from a twin-turbo 4.0-liter V8, but this variant will get an extra boost from an electric motor at the rear axle. The battery should be large enough to provide a few miles of fully electric driving.
With a significant boost in power over the GT 63 S, the GT 73’s performance should be brisk. Look for acceleration to 60 miles per hour (96 kilometers per hour) be in the two-second range. A high-tech all-wheel-drive system should provide plenty of grip in the corners.
AMG didn’t provide any specs but rumors point to the powertrain mirroring the setup in the original GT concept, which AMG quoted at 805 horsepower. Specifically, AMG said the concept featured a 4.0-liter twin-turbocharged V-8 married to a powerful electric motor capable of driving the car on its own. Currently, the GT 4-Door Coupe range tops out with the GT 63 S, whose output is 630 hp.
Although any GT 4-Door Coupe plug-in hybrid will likely weigh more than the GT 63 S, it should handily outrun it if we see anything like the 805 hp of the concept. With such an output, expect the super sedan to sprint to 62 mph in 3.0 seconds or less. The GT 63 S has already been clocked at 3.2 seconds.
Eager buyers should expect a premium price for the extra performance. The AMG GT 63 S already starts at $159,995. For this kind of money, buyers could also opt for the Porsche Panamera Turbo S E-Hybrid, also a plug-in hybrid, or the battery-electric Porsche Taycan Turbo S.
