Aston Martin has released the first audio and images of the V12 engine that will power the Adrian Newey-designed Valkyrie hypercar.
Newey, who has designed some of the most successful Formula One cars of recent decades, started work on the Valkyrie project after becoming frustrated with F1's increasingly restrictive rule book. It has been designed as part of a collaboration with the Red Bull Racing F1 team, which Newey still works for, and promises to be one of the fastest road-legal cars in the world .
