Listen To The Aston Martin Valkyrie's V12 Scream To 11,100 RPM

“An internal combustion engine without peer for a hypercar without precedent”

Though Aston Martin has done a fine job of keeping us all on our (heels and) toes with information on the Valkyrie, one of the biggest blanks left to be filled in has been the parameters of its engine. But now an array of salient details on the high-output powerplant has been revealed, and it looks like it'll be a positive game-changer.

Not least because it will rev all the way to 11,100 rpm, which is higher than just about anything else on the road. Even the Ferrari 812 Superfast (which also uses a 6.5-liter naturally aspirated V12) redlines at "only" 9,000 rpm.

The powertrain package is being developed with veteran motorsport engineering firm Cosworth and will encompass a gasoline-electric hybrid setup. But even without the electric part of the equation kicking in, the internal-combustion engine itself will produce 1,000 horsepower at a stratospheric 10,500 rpm, and (a relatively low) 546 lb-ft of torque at 7,000 rpm which will surely be filled in by the electric motor(s).

Equally impressive is how light the engine will be. At just 454 pounds, it's actually a little less than what Cosworth's last F1 engine – a 3.0-liter V10 – would weigh if upscaled to the same 6.5-liter displacement.

This despite forgoing the use of certain lightweight materials in the engine. The block is a stressed member of the chassis, and needed to be kept rigid. Cosworth also avoided more exotic alloys due to unproven longevity. But many components are machined from solid billet. The crankshaft takes six months to manufacture and weighs half as much as the one which Cosworth made for Aston's own One-77.

"To anyone with a drop of petrol in their blood, a high-revving naturally aspirated V12 is the absolute pinnacle," noted CEO Andy Palmer. "There was never any question that the Aston Martin Valkyrie would make do with anything less."
