This rumour is just hot air.
Venerated British sports car firm Aston Martin may be exploiting their tie-up with Mercedes-AMG to its fullest, having employed their biturbo V8 into the Aston Martin Vantage and made full use of Mercedes’ infotainment systems as well, but the relationship isn’t going to go any further than that.
Comments made by Aston Martin’s chief engineer (vehicle attributes), Matt Becker were mostly to blame, as he had said something at the fringes of the Geneva motor show that intimated that Aston Martin might have been looking in the way of inline-6 engines, like the kind that AMG just shoehorned into the new CLS 53. However, Becker has sought the need to clarify his statement before things get properly out of hand, and did exactly that to our friends at Motoring.
“I fear that [the rumour of 6-cylinder Astons] may have come out of one of my answers [to a question from a journalist] at Geneva. I was speaking more in general terms, that we might have to one day look at downsizing engines.” — Matt Becker, Chief Engineer (Vehicle Attributes Engineer), Aston Martin
The inline-6 that was rumoured to be sourced for Aston was likely to have been the M256 3.0-litre petrol unit, the exact engine that (as we mentioned earlier) AMG has just fitted to the new range-topping CLS coupe. However, Becker shot down the possibility of using that engine in Aston Martin’s cars, for a very practical reason:
“To be honest, I don’t know whether the engine would fit [in Aston’s cars].” — Matt Becker, Chief Engineer (Vehicle Attributes Engineer), Aston Martin
Presently, Aston Martin uses AMG’s 4.0-litre biturbo V8, which features its two turbocharges set within the ‘V’ of the engine, which produces 375kW and 685Nm in the new Aston Martin Vantage. The new V12 mill that’s utilised in the flagship DB11 is also related to an AMG design, though its thorough going-over by the chaps at Gaydon merit it being dubbed an Aston Martin unit.
