This year’s edition of The Quail: A Motorsports Gathering is going to be a sort of royal running. It’s the 20th anniversary of the event, the 25th anniversary of the Quail Rally, and two-wheelers get their 13th showcase. The show plans four featured classes and 20 debuts, one of those reveals the Zenvo Aurora. The Danish hypercar maker closed its TS model chapter last year with a TSR-GT that a driver ran up to 263 miles per hour. As with every Zenvo up to that point, motivation for that speed run came from a GM-based LS-series V8 bearing some amount of both turbocharging and supercharging. The Aurora writes at least two new chapters for the company, introducing Zenvo’s first in-house engine as well — and not just any engine, a quad-turbocharged 6.6-liter V12.
Those are larger specs than Zenvo announced earlier this year when it said the Aurora would run with a twin-turbocharged 6.0-liter V12. The Danes are working with the German boffins at Mahle Powertrain on the unit, seems one of the parties realized they had a lot more potential in their design.
Named Mjoner, the name of Thor’s hammer, the engine’s heart is a new aluminum block in a modular design so Zenvo can break off V8 and V6 mills to power Aurora offshoots. The heads hide Mahle’s Jet Ignition tech. This is the same pre-chamber ignition design Maserati uses in the twin-turbo 3.0-liter Nettuno V6; the Italians also worked with Mahle after watching sister brand Ferrari use Jet Ignition in the Ferrari F1 cars. The integration isn’t about bragging, it’s for emissions. The coming Euro 7 regulations place limits on an engine’s fuel-use trickery, Jet Ignition keeps Mjolner within regulation for the European and U.S. markets. Compatibility with synthetic fuels lends another measure of future-proofing — for the near future, at least.
Internal combustion horsepower comes to 1,232 (1,250 ps) at 8,000 rpm on the way to a 9,800-rpm redline, leading Zenvo to say this will be the most powerful road-legal V12 in the world. Electrical assistance will add another 592 hp (600 ps), taking matters to 1,824 hp. The company says the hybrid unit’s being tuned for drivability and usability. We know the combined sources will grant the Aurora all-wheel drive. It’s not clear which motor powers which axle, but our guess is that there will be a short electric-only range to satisfy stricter urban demands in Europe.
All-carbon chassis construction means a carbon tub and front and rear subframes. There are going to be two trims, Tur the slicker GT variant ready to cross Germany at more than 249 miles per hour, Agil the higher-drag and higher-aero track variant. Zenvo plans to make no more than 100 cars in total, split between the two trims. We’ll find out what they look like on August 18 during Monterey Car Week.
