Mercedes-AMG is readying a V8-powered, track-honed rival to the Porsche 911 GT3 RS, created to set new record lap times.

It will be previewed by the new Concept AMG GT Track Sport, based on the second-generation AMG GT that was launched in 2023.

While work is under way on creating the first electric AMG GT for launch in 2027 ( previewed by the recent 1341bhp Concept GT XX), Friday’s announcement confirms that AMG isn't yet done with combustion power.

The new flagship GT is likely to be a successor to the AMG GT Black Series of 2022, which produced a staggering 730bhp from a highly modified version of AMG’s twin-turbocharged 4.0-litre V8.

In the short announcement, AMG didn’t provide any technical details of the new concept but confirmed it previewed an “expansion of the GT series” that would be powered by a V8.

Given the GT Black Series was the most powerful series-production V8 ever, expect the production version of this concept to push beyond it and claim that title. 

The most powerful variant of the second-generation GT range at present is the 603bhp track-focused Pro.

Preview images shown of the new concept reveal its track-bred pedigree. It has a huge GT3-esque wing, a chunky front diffusor and wide front and rear tracks.

Given these are the first images we’ve seen of the concept, it's likely that a full unveiling will take place at September’s Munich motor show.
