Aston Martin is looking to break ties with Mercedes-AMG.

Reportedly developing a new straight-six hybrid engine to feature in future supercars, the new powerplant will give the British maker its own replacement to the German-built 4.0-litre twin-turbo V8 petrol engine provided by AMG.

The technical partnership with Affalterbach has been in place since 2013 which enabled Aston Martin to use the ubiquitous AMG mill in its DB11 and Vantage lineup. However, sources close to the new project told British outlet Autocar that a new engine augmented by electric power will replace the V8.

Potentially derived from Aston’s current 5.2-litre V12 twin-turbocharged engine, the straight-six will likely be turbocharged with a hybrid power boost. Learnings from the marque’s hybrid V6 engine built for the Valkyrie hypercar and the Rapide E project will underpin the new motor's architecture.

The growing adoption of electric drivetrains comes as tighter emissions make dinosaurs of even turbocharged petrol engines.

The British brand is locked-in to using the German’s bi-turbo V8 for at least another three years and it's ready to feature in the upcoming Aston Martin DBX crossover - the brand's first SUV. Though no technical details have been released, the new straight-six hybrid is tipped to debut in the DBX after a V12 version is released.
