1,146hp Aston Martin Valkyrie not verified...yet

Hold your horses! A Cosworth tweet citing the V12's output was "inaccurate information"

By Sam Sheehan / Wednesday, August 22, 2018

While we have no doubts that the Cosworth-built V12 engine of the Aston Martin Valkyrie will offer performance so outstanding that it will blow all other naturally aspirated engines out of the water, PH can confirm that the 1,146hp (1130bhp) output claimed on Twitter (and screenshotted by Road and Track) by Cosworth yesterday is in fact not accurate. Or at least, not yet.

Because while much of the internet has been whipped into a frenzy over the prospect of a 6.5-litre engine that breaths atmospherically to produce 1,146hp - which we should add, is 346hp more than the N/A V12 of the Ferrari 812 Superfast - it turns out the tweet that revealed that figure was in fact based on inaccurate information and put out by a junior member of staff. Pray for them.

Cosworth told PistonHeads that the Aston Martin Valkyrie’s engine is currently on the dynamometers at Cosworth’s UK facilities, and is still in the process of being calibrated. As such, Cossie still has no precise figures for its output at this stage.

As you were, then.

Still, it’s not like the final figure is set to be much below that. In fact, there’s every chance it could exceed it, given that the company making the V12 has extensive motorsport experience, which includes 176 Formula One wins, making it the sport’s second most successful engine supplier behind Ferrari.

Aston Martin has previously confirmed that the car will have a 1:1 power-to-weight ratio, which has led most to speculate an output of around 1,100hp. Even with this lower number, the Valkyrie’s motor would, to put it into technical terms, still wipe the floor with every naturally aspirated road going alternative.

We can expect the rest of the car to be just as awe inspiring as its powerplant because it has been co-developed with Red Bull Racing and its chief technical officer, Adrian Newey, who knows a thing or two about high performance cars. For F1 engineering mastermind Newey, this is a rare case of motorsport regulation-free car development. The Valkyrie is set to be more even more advanced than an F1 car.

We should know just how much more advanced when the first of these British beasts arrives with customers in 2019. Just 150 examples of the car are being produced, each priced at about £2-3 million. 25 track-only Valkyrie AMR Pros follow after that, likely with a further bump in engine performance.
