Aston Martin has had its fair share of financial difficulties lately, but this doesn't mean it's lost sight of building amazing sports cars and, now, an SUV. But what about engines? After all, the automaker currently has a deal with Mercedes-AMG to purchase the latter's 4.0-liter twin-turbo V8. It turns out this won't continue for much longer.

Autocar has learned Aston Martin will begin deploying its all-new hybrid V6 across its model lineup following its debut in the Valhalla supercar, due in 2022. "Mercedes have made no secret of where their engine technology is moving to, and obviously we don't foresee four-cylinder engines in our Astons," CEO Andy Palmer said. "So we've got to make our own journey."

Currently, the AMG-sourced V8 powers the Aston Martin Vantage and DB11 sports cars. It also sees service in the all-new Aston Martin DBX SUV.

Because it's a modular V6 featuring integrated electrical assistance, it can work with existing transmissions and, equally important, will produce just as much power as the V8, if not more. "As you move on, you normally expect a power increase, not a decrease," Palmer said. "You're supposed to do that even with a smaller power unit, so there's no way our customers are going to expect to step backwards."

Above all, Aston Martin has made clear its new V6 will be its most powerful engine to date when it debuts in the Valhalla. It'll even have to be detuned with various other adjustments for other models. Aston Martin fans will also note this is its first-ever V6, though it has a long history of building straight-sixe engines. Those concerned the V6 won't be good enough in terms of either output or sound can rest assured both issues are being handled.

The hybrid system and electric motor duo will provide additional torque to compensate for the cylinder size, and the tailpipes will be selected specifically so that the vehicles will "sound like an Aston."

"As long as it feels like a V8 and sounds majestic, I think it's a perfectly sensible way to go and a lot more sensible than a [four-cylinder] would be," added Palmer.

The new V6 will be built in the UK, while Aston Martin is making plans to move production of its 5.2-liter twin-turbo V12 from Cologne, Germany to the UK as well. Plans to upgrade with an "electrical element" are also in the works. Eventually, the V12 will be phased out due to new and more strict emissions laws, but Aston is doing everything it can to keep the V12 around for as long as possible.
