Cosworth Deletes Tweet Saying Aston Martin Valkyrie Makes 1130 Horsepower

The Aston Martin Valkyrie promises to be an outrageous beast of a machine—built using Formula 1 design principles in its V12 engine and its outrageous aerodynamics.

And as it turns out, when it hits production, it will immediately become the most powerful naturally-aspirated road car ever built, according to the folks who were tapped to make the engine:

Yes, that 6.5-liter V12 engine will make all that power—1130 horses in total—without the help of turbos or superchargers. Currently, the most powerful N/A road vehicle you can buy is the Ferrari 812 Superfast, with 789 horses from a 6.5-liter V12 engine.

The LaFerrari also made 789 horses from a naturally-aspirated V12, augmented by 161-horsepower electric motor. And that raises a question regarding the Valkyrie: Previous reports have indicated that the Aston Martin hypercar will use a Formula 1-inspired hybrid system to augment the power output of the V12. Previously, knowledgeable sources told R&T that the gasoline engine would supply around 1000 horsepower, with the hybrid system boosting total output to 1130.

Cosworth’s tweet shown above doesn’t make clear whether the 1130-hp number is from the engine alone, or the engine plus the hybrid system. It’s kind of a moot point: Even if the V12 engine makes “only” 1000 hp, that would still make it the most powerful naturally-aspirated road car engine ever built for a production car. We’ve reached out to Aston Martin to see if we can get clarification on the power output of the engine alone vs. the engine with hybrid assist; we will update this post if we get an answer.

Still, four-figure horsepower from a naturally-aspirated engine is truly amazing. We can’t wait to see what the Valkyrie does on a race track.
