Yesterday's Financial Times Deutschland reports that Aston Martin is exploring a possible cooperation with Mercedes, with engines being the most likely area for any joint efforts. I must say my initial reaction was that this is a bizarre and unlikely pairing but I suppose it does make some sort of sense. Aston is still relying, I believe, on dedicated cells or facilities within Ford plants for its engines (at Cologne of all places, for at least some of them, I think); I suppose this would allow it to break free from that arrangement.
Perhaps Aston engine production could even be repatriated to the UK if Mercedes' specialised racing engine operations here could be used, although I've no idea whether they are remotely suitable for the purpose.
Once again, proof that it's worth monitoring the German press for motor industry news that can sometimes escape the attention of UK publications.
