For perspective, insider trading on the Valkyrie road car suggests 1,130 horsepower and a 2,270-pound curb weight. A naturally aspirated, 6.5-liter V12 takes credit for most of those horses, the remainder coming from a Rimac-developed, F1-style kinetic energy recovery system. Yes, that Rimac.
The Valkyrie AMR Pro will send owners to a g-force-induced Valhalla, having more power, less weight, and "significantly increased downforce." The designers used a lighter grade of carbon fiber, replaced the windscreen and side windows with polycarbonate, traded for a lighter, molded racing seat, threw out the infotainment system, installed carbon fiber wishbones on the new suspension uprights, and bolted on smaller, 18-inch wheels that will fit the same Michelin tires used on LMP1 cars. Beyond larger front and rear wings and new programming for the active aerodynamics, Adrian Newey's team tweaked every aero surface.
Powering all that with a lustier, remapped 6.5-liter V12, Red Bull simulations show the Valkyrie AMR Pro capable of close to 250 miles per hour. Sustained cornering forces should hit 3.3g. Thanks to F1-style carbon brakes, deceleration force tops 3.5g. Here's more perspective: the Telegraph spoke to Red Bull F1 in 2010 about in-car g-forces, and wrote, "Breath control is crucial — you cannot breathe freely above 3g because to do so would expose you to the risk of passing out."
Since those numbers hint at something like ground-based flying, Aston Martin has sensibly organized a ground-based flight school. Owners will get "an intensive and comprehensive driver development program" that takes advantage of the same facilities and simulator used by Aston Martin Red Bull Racing F1. Fitness training comes with it.
If you haven't signed the paperwork for a Valkyrie AMR Pro, you're too late. Twenty-five examples — one more than the Vulcan AMR Pro — will be produced, with expected delivery in 2020, and all are sold.
