The Danish company
Zenvo Automotive is building its ‘Mjølner’ engine, which will be fitted to the Aurora. With four turbos, it will produce up to 1,250bhp — increasing up to 1,850bhp when incorporated with the electric hybrid system, making it the most powerful V12 engine ever fitted to a production road car. Developed with
MAHLE Powertrain, the heart of Aurora is a newly designed, bespoke 6.6-litre V12 engine, which will be built at MAHLE Powertrain in Northampton, alongside the hybrid system.
Jens Sverdrup, Zenvo Automotive’s chairman, said the design of Mjølner is based on experience and proven practices within the road car sector, while pushing the boundaries of performance. He said: “This engine has been carefully considered in all aspects, from the initial design phase, from driver engagement and comfort, through to meeting current and future emissions legislation around the world. Despite its high performance levels, with its 9,800rpm redline, this is a bespoke engine developed specifically for the road, rather than a compromised motorsport-derived one.
“The engine will feature the MAHLE Jet Ignition system, which has been in development at MAHLE Powertrain for over a decade and is a key enabler for ‘Lambda1’ operation, which will be pre-requisite for future emissions requirements. This engine, in V12 format, is the first implementation of a new modular architecture from Zenvo Automotive, and the concept will continue to be developed and used in different layouts across future product lines and models within the Zenvo family.”
John Hollingworth, MAHLE Powertrain’s sales and marketing director, added: “There have been some real engineering challenges along this journey, challenges that have really put our engineering teams to the test, but they have more than delivered at every step. Now, seeing the hardware come together to start the next phase of engine testing is a real achievement. It is a true testament to our engineers and the way they have risen to this challenge, developing a road engine unlike anything else in the world. We are so close to hearing the soundtrack of the Mjølner engine, and everyone is waiting with anticipation to hear that first roar into life.”
Founded in 2007, Zenvo Automotive is based in Præstø, Denmark, and is a producer of limited edition hypercars. In 2023, Zenvo revealed the all-new Aurora, a V12 hypercar that will be available in track-focused ‘Agil’ and more classic GT ‘Tur’ model designations and be limited to just a handful of cars per year. First deliveries are expected at the end of 2026.
