Engine Maker Cosworth Wants To Partner With Aston Martin On F1 Program

Aston Martin entered F1 in 2016 by joining forces with Red Bull Racing — which is aiding in the development of the Valkyrie hypercar — and it strengthened those ties ahead of 2018, signing on as Red Bull’s title sponsor. The British automaker has said its interested in becoming a power unit supplier, and has been approached by various manufacturers, reportedly including Cosworth.

“We would like to work with that partnership,” Wood told Motorsport.com. “We’ve done a lot of work with Aston for many years, we’re working very closely with Red Bull and the team for the Valkyrie, so there’s a certain logic to it.”
