The 800bhp-AMG GT73 Sedan is coming

2w ago



Mercedes-AMG unveiled the GT 4-Door Coupe Concept at the 2017 Geneva Motor Show, where the prototype model had a V8 hybrid system that produced a combined 800hp+. AMG has confirmed that this hybrid system will be put into production and have trademarked several names, strongly suggesting an upcoming variant to the current AMG GT range.

A new mysterious prototype has now been spied, which could well be something approaching a production version of the new hybrid-powered GT73.

Performance & Engineering

The Geneva concept featured a 4.0L twin-turbocharged V8 alongside a hybrid system that produced a combined 805hp.

Motor1 suggests that the 0-62mph will be dropped from 3.2s to 3.0 seconds. A common misconception is that due to extra weight, hybrids are slower than their petrol variants. This is false, compare the Mercedes-AMG E43 and E53 or the Porsche Panamera petrol and hybrid models.

Market Segment & Competition

The primary competitor is the Porsche Panamera Turbo S E-Hybrid, which produces 671hp, allowing it to accelerate to 62mph in 3.4 seconds. Could Mercedes beat this?

The only other competitor would be the upcoming BMW M8 Gran Coupe. Despite the tiny market segment, it does make sense for Mercedes to steal market share from Porsche.

The 73 Badge & Other Models

The last time Mercedes used the 73 badge, it was on the SL73 which had a 7.3L V12. However, now it's being used on a 4.0L V8 so it makes no sense and is somewhat misleading, as are most badging systems these days.

It sounds like the G-Wagen could be getting a hybrid V8 variant too...

It's believed that Mercedes has trademarked the nameplates "G73" and "S73", meaning we could be getting hybrid V8 models of those vehicles too. "GT73 4MATIC+" has also been registered, meaning it is coming.


It's likely to debut late 2019 or early 2020, are you excited?
