Aston Martin and Red Bull have revealed the first details of their track-only version of the Valkyrie hypercar.
The Valkyrie is a joint project between the two companies that has been spear-headed by the F1 team's chief technical officer Adrian Newey. One hundred and fifty road-going versions will be produced and Aston Martin has now confirmed a limited run of just 25 track cars, known as the Aston Martin Valkyrie AMR Pro.
Free of regulations surrounding road cars, the AMR Pro will feature a more powerful version of the purpose-built Cosworth V12 engine and will also have an upgraded aero kit that features much larger front and rear wings.
