Aston Martin, celebrating its centenary this year, has confirmed it has signed a Letter of Intent to form a wide-ranging technical partnership with Mercedes-Benz tuner AMG. A formal alliance deal is yet to be made though both parties are confident a definitive agreement can be reached before the end of the year.

The proposed deal will provide Aston Martin with access to AMG’s vast array of performance technology, namely its bespoke engines, but also to certain electrical systems. The firms confirm that their respective engineering teams will also work together to optimize the implementation of this technical partnership.

For the privilege, AMG’s parent company Daimler will receive a stake of up to five percent non-voting shares in Aston Martin, joining existing shareholders in the British sports car manufacturer such as Investment DAR, Adeem Investment and Investindustrial.

Rumors of such an alliance date back several years but heightened recently when it became known that Italian firm Investindustrial, which has ties with AMG from a marketing deal with its former subsidiary Ducati, was investing in Aston Martin.

Interestingly, the two firms have only mentioned V-8 powertrains, even though AMG also manufactures some of the best V-12s on the planet and already supplies them to rival firms, one of which is Pagani. It may mean that Aston Martin’s V-12 engines could continue to be sourced from Ford.

In a statement, Aston Martin production development boss Ian Minards said, “Aston Martin sources cutting-edge technology from key suppliers around the globe and the opportunity to include content from AMG in our next-generation sports cars is, clearly, good news.”

Those next-generation sports cars Minards is referring to will be a new range of Aston Martins, whose styling has already been previewed by the CC100 Speedster concept unveiled earlier in the year. The first of the new models is expected to be a replacement for the V8 Vantage.

AMG CEO Ola Källenius said of the alliance, “This is proof of AMG’s technological and performance expertise and a real win-win situation for both sides.”

Further details will be announced in the near future.
