Currently reading: Aston Martin developing straight-six hybrid powertrain
Aston's bespoke petrol-electric inline-six could replace the AMG-sourced V8 in future

Aston Martin is developing its own straight-six powerplant - possibly with hybrid tech - to eventually replace the Mercedes-AMG-sourced V8, according to a source close to the firm.

It is believed that work is already under way on the powertrain, which will be crucial to helping Aston meet tougher future emissions legislation. The most likely first recipient of the powertrain would be the soon-to-be-launched DBX crossover.

Aston Martin signed a technical partnership deal with Mercedes-AMG back in 2013. The deal allowed the British brand access to the AMG's 4.0-litre twin-turbocharged V8, which today can be found in the DB11 and Vantage coupes.

However, Autocar understands that the engine-sharing part of the deal was only ever meant to be temporary while Aston engineers work on a straight-six, which could be derived from Aston's current 5.2-litre V12.

Technical details of the engine are still firmly under wraps, but it looks likely to utilise hybrid technology developed through the brand's Rapide E programme. While a it might not be a full plug-in hybrid - Aston said last year the overall experience "isn't premium enough" for its customers yet - it should still combine the performance expected of an Aston with efficiency unheard of for the brand.

Aston will make use of the Mercedes-AMG deal for another few years yet, launching its hotly-anticipated DBX next year. That car will feature turbocharged V8 and V12 power initially, with a long talked about hybrid variant due early in the next decade.

Aston Martin DBS Superleggera 2018 road test review - hero review

New flagship super-GT has world-class fast grand touring capability, handling and driver involvement. Will Aston’s Vanquish successor be the third hit in a row for its second-century plan?

This could since the Aston Martin DB7 which was 6 supercharge from jaguar. Remember James Bond Aston Martin DB5 & DBS orginal were 6 cylinder. 6 is O.k but not 4 please.

How about half a Valkyrie with a fewer beans?

  Yeah, as someone mentioned, back in the 60’s Aston’s had a six cylinder engine, going hybrid isn’t a surprise, going with the six is because of emissions nothing else, as for full EV, saying it’s cus are too posh to plug in yet I cannot believe, there Humans just like you and me, I dare say some are wealthy enough to have a man do it for them, and I imagine an EV Aston wouldn’t necessarily be a plug in, it could use the power plate you just park over and it charges by osmosis.......?

V12 was originally developed by sticking 2 Ford V6 engines together, so why not just unstick them and make it a V6 again, surely that would be easier.

Because a V6 is completely different to a straight 6 in character and has no place in an Aston Martin.

For a while I thought every manufacturer would turn to the V formation, probably for packaging reasons.  Even Mercedes went that way with only BMW keeping the faith in straight sixes.  I have the suspicion that V sixes also don't breathe so easily and are therefore less efficient/economical.  Now that refinement and efficiency are more important it seems that everyone who dabbled with V sixes is now doing an about turn and to hell with the packaging!

Yes, that's all it is, just take two Ford V6s, add a little adhesive... It's amazing how these mistruths persist.

V12 AND L6 are "perfectly balanced" every other engine config requires a "bodge" and yes that includes V8s, perhaps that's why aston "tend to use" L6 or V12.

AM could spread its development costs by selling this new straight-6 to Jaguar. God knows, the latter seem incapable of developing a 'best-in-class' internal combustion engine these days....

Why not just extend the technical agreement with Mercedes-Benz to include the new M-B straight six?
I half suspect that's actually what is happening...

After all, the new M-B engine is already available as either a 48v mild hybrid or with even greater battery electric boost, and is getting excellent reviews...

Aston Martin going it alone to duplicate suchan engine would be an enormous waste of scarce resources for such a small company. Even Maserati and Maclaren don't develop their engines entirely in-house...

However, if going it alone is in fact what they intend to do then, yes, I agree: the straight six should be available for poor JLR who once were talking of Ingenium straight sixes, but have gone awfully quiet on that front in the past 6 months or so...
