Zenvo Mjølner Unleashed: 1,867HP Quad-Turbo V12 Road Monster Breaks Cover

Just when it felt like the hypercar world was slipping into a hybrid-electric haze, a fresh wave of pure combustion madness has reignited the flame. Bugatti is back with a monstrous V16. McLaren surprised us all with a futuristic V10 hypercar straight out of a Vision Gran Turismo dream. The Aston Martin Valkyrie finally hit the streets, and Zenvo — Denmark’s underdog supercar brand — just dropped a bombshell of its own: the Zenvo Mjølner and its thunderous new V12.

Yes, you read that right. A quad-turbocharged V12 hypercar that’s not just real but engineered for the road.

Meet Mjølner: A Name That Brings the Thunder

Named after Thor’s mythical hammer, the Zenvo Mjølner is as brutal as its namesake. At the heart of this beast lies a 6.6-litre quad-turbo V12 engine that’s been officially rated at a staggering 1,267 horsepower (1,250 bhp). And if that isn’t wild enough, it gets an additional punch from a 600hp electric hybrid boost, bringing total output to a spine-tingling 1,867 horsepower.

This isn't a track-only toy or a garage queen. Zenvo designed the Mjølner specifically for road use, and it meets current and even upcoming global emissions standards — a major feat for a boutique manufacturer crafting a powertrain of this scale.

Built in Britain, Engineered for the Future

The V12 engine is being assembled by Mahle Powertrain in Northampton, UK, utilizing the company’s innovative Jet Ignition system. This advanced technology has been more than a decade in the making and allows the engine to run under ultra-lean Lambda 1 combustion conditions, helping it meet tough emissions regulations without sacrificing performance.

In short, this isn’t just another monster engine that needs a pit crew to start up. It’s engineered for the real world, designed to be driven, and built to be sustainable — at least as sustainable as a V12 hypercar can be.

A Modular Marvel with Massive Potential

This powerplant isn’t just a one-off. It’s the first to be developed on Zenvo’s new modular engine platform, opening the door for future variants. Think twin-turbo V8s or even a monstrous V16 version if Zenvo really decides to push the envelope. But for now, all eyes are on the Mjølner as the spearhead of the brand’s most ambitious project to date: the Aurora hypercar program.

Zenvo says the completion of the engine marks a major leap forward in development, and the company is pushing ahead rapidly. In an era where the hypercar scene is more competitive than ever, Zenvo clearly understands the need to move fast — and make noise doing it.

Turning the Volume Up to 11

Zenvo Chairman Jens Sverdrup put it best:

“Sound and visceral drama is what Aurora will be all about, and the engine is a vital element in this, which we will turn up to 11. At Zenvo, we are a team of passionate, genuine ‘car guys’, and it is not every day that a V12 engine is born. It’s a very proud moment to finally showcase Mjølner.”

He also noted that chasing records wasn’t the goal — achieving the most powerful road-legal V12 engine ever built was simply a natural result of Zenvo pushing the limits of what’s possible.

What’s Next for Zenvo and the Mjølner?

The next big moment will be hearing that quad-turbo V12 scream on the dyno — and eventually, on the open road. With a 9,800 rpm redline, a hybrid powertrain, and an emissions-compliant build, the Mjølner promises to deliver a rare blend of ferocity and future-readiness in a market dominated by electrification.

As the hypercar landscape shifts, Zenvo's Mjølner stands out as a defiant statement of combustion-powered excellence. It’s not just a car — it’s a declaration that the V12 is alive and well, and still capable of taking your breath away.
