Two things of note here.
The short of it is that if you want to make a car with a power to weight ratio of 1:1, you can’t afford to mess about. And if you’re any of Adrian Newey/Andy Palmer/Aston/Red Bull, or anyone else charging the other side of £2m on a hypercar, for that matter, you’d be disinclined to pick any duffers to work with.
Of all the announced partners, the three headliners are Cosworth, Ricardo and Multimatic, and they’ve all got form in their respective fields.
Aston Martin says that its V12 engine is its own, but Cosworth has long been an Aston supplier and technical partner. And it’s no stranger to race engines, which the 001’s powerplant might as well effectively be, given the power and weight requirements.
