Full details and images of the Aston Martin Valkyrie AMR Pro have emerged, and it's clear that this is one of the most extreme hypercars ever built.
Developed, like the road car, in partnership with Red Bull Advanced Technologies, the track-only 2021 Aston Martin Valkyrie AMR Pro is heavily based on the racer that was originally created to win the new Le Mans hypercar class.
While that race car will never hit the track, this AMR Pro version has emerged as something much, much quicker.
How fast? The definitive answer is "F1 fast", says Aston, while on the famous 13.7km-long La Sarthe circuit, the most extreme Valkyrie is capable of a 3:20min lap.
That time is comfortably faster than the first-gen Porsche 919 Hybrid and would be enough to make the wild new Valkyrie a front-runner.
To turn the already bonkers road-going hypercar into an all-out track weapon, huge changes were made under the watch of Red Bull chief engineer Adrian Newey.
For starters, the AMR Pro sits on what's described as a 'unique' version of Valkyrie's carbon-fibre monocoque that features a 380mm-longer wheelbase.
Up front, there's a 96mm-wider track, while at the rear the space between the wheels increases by 115mm. Both boost mid-corner grip, with the Valkyrie AMR Pro now claimed to be capable of pulling more than 3G lateral acceleration.
Since the body of the Valkyrie AMR Pro was created without any FIA or race series rule constraints, designers have gone completely wild.
Hence why the Aston track day toy is 266mm longer than the road version and has a reworked underbody and a comically large rear wing that will produce levels of downforce only F1 drivers will be used to.
Under the rear boot lid, engineers have torn out the road-going Valkyrie's heavy battery-electric hybrid parts and junked them.
In its place remains a hotter take on the Cosworth-developed 6.5-litre V12 that revs to 11,000rpm.
Aston hasn't yet revealed how much weight it's saved from deleting the electrification, but further kilo-cutting involves ultra-lightweight carbon-fibre bodywork, carbon suspension wishbones and Perspex windscreen and side windows.
Again, no numbers have been released but it's thought the AMR Pro will tip the scales at less than 1000kg, even with its huge new wings.
Aston Martin says it will make just 40 examples of the Valkyrie AMR Pro, plus two prototypes. All will be left-hand drive but since none can be registered for road use, there's no reason why a small number won't head Down Under.
It's thought Aston Martin will charge around £3 million ($A5.5m plus local taxes) for each one when first deliveries begin in the fourth quarter of 2021.
For that, Aston Martin will throw in track tuition and special track days restricted to Valkyrie owners.
With final physical testing about to begin, Aston has confirmed both Aston Martin Cognizant Formula One drivers Lance Stroll and three-times F1 world champion Sebastian Vettel will both be part of what could be the fastest on-track hypercar ever made.
