Aston Martin spills the beans on the AM-RB 001 drivetrain

One of the most closely guarded secrets in the recent hubbub of hypercar development has been the powertrain for the AM-RB 001. Red Bull’s technical chief Adrian Newey has remained elusive for months on the subject, hinting only at a 12-cylinder configuration, and one that eschews forced induction.

Today the spotlight is finally on who and what will put the Aston Martin Reb Bull joint venture up the road, and it makes for some tantalising reading.

The engine will be a 6.5-litre V12 built by Cosworth, normally aspirated, and expected to generate 1000bhp. It will be mated to a bespoke seven-speed paddle shift transmission designed and built by Ricardo that promises to be both compact and impressively lightweight.

This initial drivetrain will also be coupled to a hybrid battery system developed in conjunction with WCS’s good friends at Rimac, one of the world leaders in battery-led high performance.

Aston’s long-standing relationship with Multimatic will continue in the production of an all-carbon monocell. Multimatic have a proven track record with highly specialised Aston projects, having worked on the One-77 and Vulcan track car. They will now blend their expertise with Red Bull’s own not inconsiderable grasp on carbon fibre manufacture garnered through years at the sharp end of Formula 1.

The AM-RB 001 will have a 1:1 power-to-weight ratio, thrusting it into almost unchartered performance territory, especially for a car its makers are keen to remind us will be a civilised and tractable daily driver.

Newey is full of confidence however, and deliveries are slated for early 2019: ‘Much like Formula One, designing, engineering and building a car like the AM-RB 001 is a massive team effort. To achieve great things you need to surround yourself with the best people.’ The CVs are certainly impressive and the numbers astonishing. It’s going to be a challenging, fascinating couple of years…
