The Aston Martin Valkyrie’s top-secret power figure appears to have been leaked online, with a tweet from engine supplier Cosworth claiming it will produce a staggering 1130bhp (830kW) – making the British hypercar the most powerful naturally aspirated road car in the world.
In a Tweet today, Cosworth said: “We’re famous for breaking records and our latest engine, the Aston Martin Valkyrie 6.5-litre V12, will be the world’s most powerful naturally aspirated road engine with 1130bhp.”
Famous for breaking records and embargoes, it seems, as the Tweet was quickly deleted soon after. In fact, Cosworth was soon backpeddling, telling American motoring publication Road and Track that “no precise figures related to the engine have been confirmed”.
Aston Martin is also yet to confirm the news, so here’s what we do know for certain instead. We know the Valkyrie will use an F1-inspired KERS system to supplement engine power, and we know that the prodigious power will be fed through a seven-speed automatic gearbox. We also know that, if those numbers are proven correct, that the Valkyrie shades the AMG Project One by some margin, with the German take on an F1-inspired road car good for 761kW.
Just 175 units of the Valkyrie will be built in total (and 25 of those will be AMR Pro track-only race cars), with pricing expected to start from around $4m when they begin to arrive next year.
