Aston Martin’s track version of its Valkyrie hypercar, the AMR Pro, isn’t out until 2020, but it appears likely that the production version could end up being even more exciting than the official figures – including peak power of 1100bhp and a 1000kg weight with the same in downforce – have so far suggested.
Red Bull Racing’s Adrian Newey, who has led the car’s development alongside Aston creative director Marek Reichman, said: “The downforce we are quoting is obviously early days.
The model you see now is effectively the ideas that stand behind the project given over to Marek’s team to interpret. It will, of course, change quite a lot from that.” In other words, it could get even quicker.
Newey also admitted that the Valkyrie came close to having a radically different engine from the chosen V12. “I spent a lot of time looking at different power units,” he said. “The obvious choices were a V6 – either single or twin-turbo – or a high-revving, naturally aspirated V12.
“In the end, I came to the conclusion that it should be the V12 because of what that allowed us to do in terms of structural mounting, because it’s a very well-balanced engine with good NVH characteristics. With a turbo, you need intercoolers; by the time you’ve put those on, the weight is fairly similar. Technically, the V12 was marginally superior, but it was a close call.”
