In November 2017, Aston Martin had announced that they’re building 25 track-only examples of the Valkyrie. Here are some details.
The track-only Valkyrie generates more than 1000 kg of downforce. To achieve this, the AMR Pro’s aerodynamic surfaces have been revised. Most obvious changes are wider bodywork, much larger front and rear wing elements, and revised active aerodynamic control strategies tailored for the demands of track driving.
In order to save weight, this bodywork uses a lighter construction of carbon fibre. Heater/de-mister blower and infotainment screens fitted to the road car has been removed. Furthermore, usage of ultra-lightweight track-specific components such as a polycarbonate windscreen (with heater elements) and side windows, carbon fibre suspension wishbones, moulded race seats and a lighter exhaust system ensure the AMR Pro hits its 1000 kg weight target.
Calibration changes to the 6.5-litre naturally-aspirated V12 engine’s emission control systems and re-programming of the Energy Recovery System control software will result in a combined power output of more than 1100 bhp – more than the Valkyrie road car and a figure than comfortably exceeds the magic 1:1 power-to-weight ratio. That’s to say more than 1 bhp to propel every kilogram of mass.
The British brand further said that even in high-downforce track configuration, the AMR Pro is still capable of hitting 225 mph (362 km/h). Of far greater benefit to lap time is the track-only Valkyrie’s ability to achieve lateral acceleration in excess of 3G – a figure far beyond that of any other car derived from a fully homologated road car.
Commenting from the Geneva Show stand, Aston Martin’s Chief Executive Officer, Andy Palmer, said: “Anyone who knows me will tell you I’m a true racer at heart, so to see the track-only Aston Martin Valkyrie AMR Pro together with Aston Martin Red Bull Racing’s Formula One and Aston Martin’s World Endurance Championship cars here at Geneva is fabulous. I’m starting to get used to some of the extraordinary things Adrian (Newey), Red Bull Racing, Aston Martin and all our exceptional technical partners – now including Mobil 1 and Esso as Valkyrie’s official oil and fuel partners – are capable of, but the Aston Martin Valkyrie AMR Pro is something truly mind-bending.”
Speaking at the debut event, Christian Horner, Team Principal of Aston Martin Red Bull Racing said: “It is hugely rewarding to see the Valkyrie AMR Pro unveiled here in Geneva, another evolutionary step in the relationship between Red Bull Racing and Aston Martin. We set out together with an ambitious and pioneering road map to create something extraordinary in partnership, and the Valkyrie AMR Pro is yet another turn of that wheel.”
Just 25 Aston Martin Valkyrie AMR Pros will be built. Deliveries are expected to commence in 2020. All cars are sold out.
