Mercedes-AMG’s super-powered answer to the Porsche Panamera Turbo S E-Hybrid has been caught with its bonnet up
31 May 2019

Mercedes-AMG is preparing to launch its most powerful model yet next year: a plug-in hybrid version of the GT 4-door Coupé.

Likely to be dubbed GT 73 4Matic, for which a trademark was recently applied, the petrol-electric flagship is expected to produce around 800bhp, if not slightly more.

New spy shots show what initially looks like just another GT 4-door Coupé prototype being put through its paces by engineers. However, a view under the bonnet reveals a complex electrical system - almost certainly that used by an electrified powertrain. The photographers who took the images also claim the test mule drove away silently on electric power.

AMG boss Tobias Moers confirmed to Autocar at the Geneva motor show that the model will launch in 2020. He also revealed the powertrain will remain largely faithful to that of the GT Concept shown at the 2017 Geneva motor show.

That made use of AMG’s twin-turbocharged 4.0-litre V8 petrol engine with an electric motor on the front axle, giving a combined system output which Moers claims is “up to 600kW” - or 805bhp. That compares strongly to the Porsche Panamera Turbo S E-Hybrid, which makes do with 671bhp. 

Despite a fairly substantial increase in weight that goes along with the hybrid system, the GT 73 should be capable of breaking the three-second barrier in a 0-62mph sprint. The GT 63 S manages the same sprint in 3.2sec. Yet it’s not all about fast launches; the system will also allow an all-electric range of up to 31 miles and, as a result, far greater claimed economy than any other GT 4-door Coupé

The '73' branding has only ever been reserved for a select few of AMG’s most powerful models throughout history. The last was the SL 73, a super-rare version of the 1990s R129 SL that used a 7.3-litre V12. That motor then went on to power the Pagani Zonda supercar.

Sorry, but I think this amount of power in a Saloon is irresponsible, this is just a power game not a game changer, you don’t need that much power to go that fast, it’s getting to the point where sport/super/hyper cars are one, it’s just the number of seats that separating them.

been tested yet? Better have a car you'd love to rev to the max maybe 10 percent of the times, than a car that scares the sh.t out of you with its explosive power the moment you just look at the pedal.

The view under the bonnet reveals standard test trip instrumentation on everything .  There's no HV orange cables in sight so I'm not sure how you conclude a complex electric powertrain....

It'll be another compliance hybrid with a bit of an electric mode and a performance boost.  Shame considering where they were over 5 years ago with the AMG eSLS - a propoer performance BEV. 

The biggest legacy of the Zetsche years is not carrying on with EV developments when they had momentum eg dual mode alliance, eSLS, Bclass BEV.  All of these could have been built on but are sadly now just opportunities missed.

and 2.5s 0-60 time and weigh 2.2 tonnes.

Apart from the MX5  :)

I know what I'll be driving.....
