Marvel at the Aston Martin Valkyrie’s 6.5-Liter V-12

The Aston Martin Valkyrie is inching closer to production, and that means concrete details are beginning to trickle out. Today, the British sports car builder has released detailed specs for the Valkyrie’s primary motivator, its naturally aspirated 6.5-liter V-12 engine that produces 1,000 hp.

Aston says it wanted a naturally aspirated engine from the outset of the project, which was originally code-named AM-RB 001. Working with renowned engine tuner Cosworth Engineering, Aston Martin developed a 65-degree 6.5-liter V-12 that revs to 11,100 rpm and makes 1,000 hp at a stratospheric 10,500 rpm. Torque, on the other hand, is nearly half that at 546 lb-ft, and arrives at a still-high 7,000 rpm. As we previously reported, the Valkyrie will be a hybrid hypercar, so an electric motor (or two) will be employed to complement its peaky 12-cylinder gas engine. Aston says it will detail the Valkyrie’s hybrid system at a later date, however.

But even without that info, there’s plenty to unpack with just the Valkyrie’s internal combustion engine. For example, the V-12 produces 153.8 hp per liter, an incredible amount for a naturally aspirated car. Additionally, the engine weighs just 454 pounds. To put that into perspective, Aston says Cosworth’s 3.0-liter V-10 used in Formula 1 weighs 214 pounds, but if it were scaled up to 6.5 liters it would come in at 463 pounds. Much of the savings comes from internals machined out of solid aluminum or titanium billet, including the crankshaft, connecting rods, and F1-spec pistons. According to Aston Martin, the Valkyrie’s crankshaft is 50 percent light than the One-77’s.

We still have some time before the first Aston Martin Valkyries are delivered, so expect more details to surface as we get closer. In the meantime, enjoy this gallery of engine porn courtesy of Aston Martin.
