Denmark, 04 April 2025 – Zenvo Automotive has unveiled a groundbreaking advancement in high-performance automotive engineering with the introduction of the Mjølner powerplant. This monumental engine, a 6.6-litre twin-turbocharged V12, pushes boundaries by producing an astonishing 1,250bhp, escalating to a mind-bending 1,850bhp when combined with its state-of-the-art hybrid system. Developed in partnership with MAHLE Powertrain, this engineering masterpiece marks a significant milestone in the ongoing Aurora programme.
A Revolution in Automotive Power
The heart of the Aurora, Mjølner, represents an uncompromising blend of raw performance and technological sophistication. Designed from the ground up to prioritise driver engagement and sensory exhilaration, this hand-built power unit boasts a remarkable 9,800rpm redline, ensuring an experience unlike anything else on the road. Jens Sverdrup, Chairman of Zenvo Automotive, describes it as the “beating heart” of the Aurora, embodying the very essence of driving passion.
Zenvo’s ambition was never to simply create the most powerful production V12—it was to push the boundaries of what is possible in a road car. The result is an engine that not only sets a new performance benchmark but also delivers an intoxicating aural and visceral driving experience that enthusiasts crave.
Pioneering Hybrid Technology with MAHLE Jet Ignition
Zenvo’s collaboration with MAHLE Powertrain has ensured that Mjølner is as forward-thinking as it is powerful. The engine features the cutting-edge MAHLE Jet Ignition system, a revolutionary technology refined over a decade to optimise efficiency and meet stringent global emissions regulations. The system enables Lambda1 operation, a critical requirement for future emissions standards, ensuring that Mjølner is not just compliant today but prepared for the regulatory landscape of tomorrow.
This technological leap ensures that the Aurora powertrain is not a mere adaptation of motorsport-derived concepts but a purpose-built road car engine, engineered with both performance and long-term usability in mind.
A New Modular Engine Architecture for Zenvo’s Future
The Mjølner engine also marks the debut of Zenvo’s modular engine architecture, a versatile platform designed to be adapted into various configurations for future models. This strategic innovation underscores Zenvo’s long-term commitment to engineering excellence and sustainable high-performance powertrains.
John Hollingworth, Sales & Marketing Director at MAHLE Powertrain, hails the project as a “labour of love” for the engineering teams involved, overcoming immense technical challenges to deliver an engine unlike anything seen before. “Now, seeing the hardware come together to start the next phase of engine testing is a real achievement,” Hollingworth remarks. “We are on the cusp of hearing Mjølner roar to life, and it will be a defining moment in automotive history.”
Looking Ahead: The Dawn of Aurora
As Zenvo progresses with the Aurora programme, extensive testing of the Mjølner powertrain will commence, bringing the world one step closer to experiencing this revolutionary powerhouse. With performance figures that defy belief, emissions compliance that sets new industry standards, and a driving experience designed to be truly immersive, the Mjølner engine cements Zenvo’s place at the forefront of hypercar innovation.
Stay tuned as Zenvo prepares to unleash the full force of Mjølner, an engine that is set to redefine the supercar landscape and inspire a new generation of automotive engineering.
