When the Mercedes-Benz 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.
AMG on Thursday released a photo of a new GT 4-Door Coupe variant due to be revealed on September 1 ahead of a formal debut the following week at the new Munich auto show. The new variant is expected to be a plug-in hybrid range-topper, the first in the line of electrified AMGs carrying the new E Performance branding. The One hypercar was meant to be the first but delays have pushed back its launch.
The GT 4-Door Coupe plug-in hybrid will now have that honor. It is expected to carry a new GT 73 designation, though GT 63e has also been rumored. What we do know is that its powertrain will feature a 4.0-liter twin-turbocharged V-8 mated to a 9-speed automatic up front and a single electric motor mated to a 2-speed transmission at the rear.
There will also be a 6.1-kilowatt-hour battery kept charged primarily to provide power during high-performance driving, though a small electric range will also be possible. Drive will be to all four wheels via a conventional all-wheel-drive system.

Peak output of the system is expected to be 804 hp. Currently, the GT 4-Door Coupe tops out with the GT 63 S, whose output is 630 hp. With so much extra juice, the 0-60 mph time should slip under 3.0 seconds. The GT 63 S has already been clocked at 3.2 seconds.
Eager buyers should expect a premium price for the extra performance. The 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. There's also the Tesla Model S Plaid and upcoming Lucid Air Dream Edition Performance, both of which deliver more than 1,000 hp.
AMG doesn't have an answer to those electric super sedans just yet, though a tamer AMG-tuned EQS is due out later this year. We should also see it in Munich.
