Aston Martin Valkyrie’s V12 Engine Offers Insane Horsepower

The Aston Martin Valkyrie is a special car, but it turns out, it's V12 engine packs a big punch.

Aston Martin Valkyrie’s V12 Engine Offers Insane Horsepower

The Aston Martin Valkyrie will have one of the most powerful naturally aspirated engines in the world, according to a new report.

In the world of hypercars, things are moving in a very specific direction--towards electricity. Porsche’s Nurburgring-crushing 919 Hybrid Evo used a hybrid powertrain to great effect in its record-breaking run around the ‘Ring, and future versions of hypercars from Koenigsegg to McLaren are all looking towards hybrids to power their future vehicles.

Not Aston Martin. The bespoke British supercar manufacturer has said “no” to a hybrid, and instead opted for the biggest engine that could possibly fit in a speed-focused car: a 6.5-L naturally aspirated V12.

Neither a supercharger nor turbocharger will sully the greatness of this engine.

How much power can a naturally aspirated V12 generate? About 1,130 horses worth.

According to Motor Authority, the Valkyrie will have the most powerful naturally aspirated engine on any road-going car, ever. Their source is a tweet from Cosworth, the British engine manufacturer that provides most of Aston Martin’s engines. That tweet has since been deleted, so maybe Cosworth spoke a little too soon.


That said, we can’t think of a more powerful naturally aspirated engine in a hypercar, so it’s hard to say why that tweet got the kibosh. There are certainly more powerful truck engines, to be fair, but they’re usually hauling thousands of pounds of produce and not zooming around a race track at over 200 mph.

Apparently the use of a V12 was a hotly debated topic within Aston Martin. Most other carmakers have switched to smaller engines with larger turbos for efficiency reasons, but according to Adrian Newey of Red Bull Racing (and speaking to AutoCar), they decided on the V12 due to “mounting” reasons.

“In the end, I came to the conclusion that it should be the V12 because of what that allowed us to do in terms of structural mounting, because it’s a very well-balanced engine with good NVH characteristics,” he said. “With a turbo, you need intercoolers; by the time you’ve put those on, the weight is fairly similar. Technically, the V12 was marginally superior, but it was a close call.”

Each Valkyrie will cost $2.6 million each with all 175 examples already sold. We’ll have to wait until one of those decides to lap the ‘Ring to see how well that big V12 will stack up.
