Did someone just leaked the Aston Martin Valkyrie's engine output accidentally? Seems like Cosworth which is in charge of developing the engine, did so recently.

As reported by Road & Track, Cosworth recently tweeted "We're famous for breaking records and our latest engine, the Aston Martin Valkyrie's 6.5-litre V12, will be the world’s most powerful naturally aspirated road engine with 1,130bhp"

Naturally, the leaked figure has since been deleted on Twitter but blunder or not, 1,130bhp is still a very impressive number for a naturally-aspirated engine. That said, it remains to be seen whether that figure is achieved with the help of a hybrid powertrain or not.

The most powerful naturally-aspirated road car engine is currently being held by the Ferrari 812 Superfast which has 789bhp from its 6.5-litre V12 engine.
