Meet the most extreme AMG GT yet: carrying on where the Black Series left off

Could an even more extreme Mercedes-AMG GT be on the way? Faster still than the monster GT R version?

These photos suggest so. Spied testing on the road and at the Nurburgring Nordschleife circuit, this AMG GT variant is thought to be a road-going version of the recently launched Mercedes-AMG GT4 racing car.

It’s thought that the fastest AMG GT road car yet may carry the Black Series title, reserved for AMG’s wildest models. If that’s the case, it would be a natural successor to the SLS AMG Black Series of 2013.

But it looks pretty much the same as the existing AMG GT R?

Biggest giveaway is the exhaust arrangement – like on the GT4 racer, the tailpipes are integrated into the diffuser on the left and right. The regular AMG GT R has a central exhaust exit, plus the two extra pipes on either side - but the car pictured here doesn't include the centre exhaust exit.

The diffuser and fixed rear spoiler appear otherwise similar to those of the existing GT R, but further aero developments are likely to follow, together with minor styling tweaks to separate the models. The GT R is already an enormously wide car, but this variant could grow wider still.

Expect less weight, courtesy of reduced sound deadening and lightweight components, and more power too – although the GT R is already pretty well-muscled at 577bhp, we already know the same 4.0-litre twin-turbo V8 engine is capable of being stretched to 600bhp+ from its duties in the E63 AMG saloon and estate.

Further spyshots in the gallery show the disguised car being back-to-back tested with the GT R on the Nordschleife. It’s being pushed to the limit, and indeed a bit beyond in a few of the photos…

Will this new model really be called the AMG GT Black Series?

It seems likely; AMG boss Tobias Moers has previously hinted that a Black Series AMG GT model is in the works.

Although the GT4 name has previously been rumoured, to tie in with the racing car, it seems unlikely – the same name is already being rumoured for an upcoming four-door AMG GT model, and besides, it numerically implies a lower level of performance than Porsche’s trademarked GT3 model name…
