Hybrid V6 will first be used in 2022 Valhalla, then in 2023 Vanquish.
All-new engine will gradually replace current AMG-sourced V8, while Ford V12 production will be brought back to UK.
Aston Martin’s hybridised V6 will rapidly be deployed across most of the marque’s range once it has made its debut in the Valhalla, Automotive Daily’s partner Autocar has learned.
The all-new powerplant, due to enter production in 2022, will replace the Mercedes-AMG 4.0-litre V8 that’s used in the Vantage, the lower reaches of the DB11 range and the soon to be launched DBX SUV.
“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 told Autocar. “So we’ve got to make our own journey.”
With integrated electrical assistance, the Aston Martin V6 should effectively be a modular replacement for the AMG V8, with Palmer confirming that it can be mated to existing transmissions.
Just as importantly, it will make at least as much power as the AMG engine in these applications.“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.”
Aston Martin confirmed the new engine would be its most powerful yet when used in the Valhalla but that it would also be detuned and reconfigured to suit a variety of needs.
The British company has a long history of making straight sixes but has never done a V6 before. However, Palmer insists it will be possible to make sure it delivers a brand-appropriate experience. “The key is sound,” he said. “Tuning the pipes to make it sound like an Aston.
“Obviously we can use the hybrid system and the electric motor to fill in on torque, so you can compensate for the cylinder size with the electrical assistance.
“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.”
The V6 will be made in the UK by an as-yet-unspecified supplier. Automotive Daily’s partner Autocar has been told that it definitely won’t involve Ford’s soon-to-be-closed engine plant nearby, despite its proximity to the new Aston Martin factory in St Athan.
We have also learned from insiders that Aston Martin is planning to move production of its twin-turbocharged 5.2-litre V12 engine to the UK (it’s currently made at a Ford factory in Cologne, Germany), with the plan being to add an electrical element.
Aston Martin sold nearly 1800 V12-powered cars last year, and repatriating the powerplant to the UK shows a continued commitment to it.
“You can see in the longer term that it won’t last,” Palmer admitted, “but certainly over the next few years, we can continue to produce V12 engines, and we can make them more CO2-friendly.”
While the UK government’s planned ban on the sale of all new petrol and diesel-fuelled cars – including hybrids – by 2035 will create big challenges, Palmer echoed McLaren boss Mike Flewitt by confirming his company won’t stop developing part-combustion cars for other markets if demand is still there.
“The key point is that we make cars for the world, and the world hasn’t said there isn’t a future for hybrids or plug-in hybrids,” said Palmer.
“If we were only selling to the UK it would be different, but we’re selling to a worldwide market where there’s a variety of views on future technology and how it will be deployed.”
We also asked Palmer about Aston Martin’s withdrawal from the planned hypercar class in the World Endurance Championship after previously indicating that it would join.
“They changed the rules, nothing more, nothing less,” he explained. “They allowed in IMSA vehicles. It was nothing to do with the state of the company, nothing to do with internal politics, nothing to do with anything other than that [Le Mans organiser] the ACO destroyed the business case.
“We were led to believe we were going to be racing hypercar against hypercar, but we didn’t anticipate there would be a lower-cost way of racing a year later. The whole case just fell to pieces.”
