Aston Martin has announced it is developing a new turbocharged 3,0-litre V6 engine, effectively confirming its move away from Mercedes-AMG’s twin-turbo 4,0-litre V8.

Under a technical agreement between the two companies, many current Aston products – including the base DB11Vantage and new DBX – currently employ a version of Affalterbach’s twin-turbo 4,0-litre V8 petrol engine. But that's going to change in the near future.

The Gaydon-based firm says the new “in-house-designed” V6 engine will be used in a new range of mid-engined sportscars, starting with the Valhalla from 2022.

The V6 powertrain (codenamed “TM01” to tip a hat in the direction of Tadek Marek, an Aston Martin engineer of the 1950s and ‘60s) will be electrified, allowing it to become the “most powerful” example in the Aston Martin range when it goes on sale.

Aston says the powertrain’s power and torque figures for each application will be determined by the “desired characteristics of each product it serves”.

The engine was developed with a “hot V” structure and will be positioned “directly behind” the driver’s cabin and equipped with a dry sump system.

“Investing in your own powertrains is a tall order, but our team have risen to the challenge. Moving forward, this power unit will be integral to a lot of what we do and the first signs of what this engine will achieve are incredibly promising,” said Andy Palmer, Aston Martin president and CEO.
