# Cosworth Confirms Aston Martin Valkyrie Will Have World’s Most Powerful Naturally-Aspirated Engine

The $3.3 million [Aston Martin Valkyrie](<https://www.thedrive.com/new-cars/19120/aston-martin-valkyrie-amr-pro-generates-more-than-its-own-weight-in-downforce>) is one of the most ambitious hypercar projects in recent memory, a moonshot of a machine that's intended to herald in the next chapter for the storied British marquee. It's basically a street-legal Le Mans prototype, and after teasing us with a [mysteriously deleted tweet,](<https://www.thedrive.com/news/23059/cosworth-reveals-aston-martin-valkyrie-will-have-earths-mightiest-naturally-aspirated-street-car-engine>) engine supplier Cosworth has finally confirmed the Valkyrie will have a powertrain to match: a naturally-aspirated V12 in the neighborhood of 1,100 horsepower, making it the most powerful such engine ever used in a road car.

[Speaking to *Top Gear,*](<https://www.topgear.com/car-news/future-tech/cosworth-aston-valkyrie-engine-could-have-1100bhp>) Cosworth CEO Hal Reisiger said that the Valkyrie's 6.5-liter V12 is being developed to put out “two to three hundred more horsepower” over any other V12 setup on the market. The 6.5-liter V12 in the Ferrari LaFerrari produces a maximum of around 950 hp when the car's hybrid KERS system kicks in—on a conservative end, Reisiger is hinting at a design that will deliver at least 1,100 hp.

We don't know if he's talking straight engine power or a hybrid total, but either way it's an eye-popping number. No word on that weirdly-deleted tweet either, but hopefully it didn't cost anyone their job.

"\[We're\] not only responsible for designing the engine but manufacturing, assembling and testing it," [Reisiger told *Top Gear*.](<https://www.topgear.com/car-news/future-tech/cosworth-aston-valkyrie-engine-could-have-1100bhp>) "I’m happy to say we are on schedule for that too."

Ideally the rest of the car is too, because Aston Martin is promising some [deeply wild](<https://www.thedrive.com/article/12371/these-are-the-newest-renderings-of-the-aston-martin-valkyrie>) stuff here. The car's advanced aerodynamics feature giant undercarriage tunnels (called venturis) that look big enough to hold a body, its infotainment-free interior comes with custom-molded racing seats and a removable steering wheel—and oh yeah, it's already sold out.
