While it’s been known since the car was announced that it’d be a V12, we now know the nitty gritty details of this all-new engine. Developed in partnership with MAHLE powertrain, the engine nicknamed ‘Mjolnir’ will be all-aluminium, displace 6.6 litres, have no less than four turbochargers and, in spite of them, rev to a peaky 9,800rpm. The engine will also be flexfuel and synthetic fuel compatable, for net zero-emission running. Right from the off, this is intended to be a globally emissions-compliant engine.
An image shows four turbochargers sat atop but just inside the ‘V’ of the engine, where the exhausts appear to exit. A throttle body can be seen hanging off the underside of the cylinder head. Exhausts and inlet usually sit the other way round but this reversed head design is nothing new, with Koenigsegg most recently redesigning its V8 in a similar way in order to package it in the Gemera.
The Aurora’s engine is described as the most powerful and technologically advanced production car V12 built to date. While the engine itself is said to produce at least 1,267PS (932kW), it’ll still be augmented in the Aurora by a 608PS (447kW) hybrid system, for a total output of 1,875PS (1,379kW).
Pulling on MAHLE's technical expertise, particularly in modular engine platforms, the engine has been designed from the ground up to be the base for a family of motors. This one is presumably the largest configuration, with Zenvo saying that V8 and V6 derivatives are planned. These will presumably displace 4.4 and 3.3 litres and could be destined for anything from junior models to, says Zenvo, crate motor offerings for other marques. If that doesn't say confidence in the platform, we don't know what does...
