Aston Martin has revealed the 1000bhp Valkyrie AMR Pro, an 'extreme' track-only version of its new hypercar featuring a purely combustion-engined powertrain, which the firm claims can lap the Le Mans 24 Hours circuit in 3mins 20secs.
The new machine is based on development work for now-abandoned plans to develop a Le Mans Hypercar racing version of the Valkyrie that was developed by Aston, Red Bull Advanced Technologies and engineerting firm Multimatic. The original study resulted in a concept car shown at the 2018 Geneva show, which Aston described as an optimised track version of the road car.
The Valkyrie AMR Pro is a development of that concept, and because it does not need to meet motorsport regulations, Aston says it has been able to go further in several areas. The firm claims that the capabilities of the news machine 'far exceed' the original concept.
Aston boss Tobias Moers said: "Valkyrie AMR Pro is a project beyond compare, a true ‘no rules’ track-only version. The Valkyrie AMR Pro is testament to Aston Martin’s commitment to pure performance and this performance DNA will be evident in our future product portfolio."
Red bull tech chief Adrian Newey described the AMR PRO as "an Aston Martin Valkyrie on steroids." He added: "Its performance output is at a very high level, much higher than any other previous track-only car, and well in excess of a top-class LMP car of today.”
Without needing to meet racing regulations, Aston has pushed the design of the Valkyrie AMR Pro further, extending the wheelbase by 380mm and the chassis track by 96mm at the front and 115mm at the back. It also gains a dramatic new aerodynamic package that adds 260mm to the overall length of the car, and which Aston claims offers more than twice the downforce of the road car.
The aerodynamic package makes extensive use of underbody and overwing airflow to develop downforce, and Aston says enabled it to generate lateral acceleration of more than 3G.
