A Mad Genius Is Stuffing An Inline-Six Engine Into The BMW i8

Through the years, we’ve talked concerning the i8 variations that by no means have been. For instance, BMW aficionados will keep in mind the hydrogen prototype with a gas cell. An excellent spicier concept left on the proverbial reducing room ground was a V10-powered machine utilizing the high-revving S85 engine. There have been additionally rumors of a four-cylinder variant, however that didn’t materialize both.

Finally, the plug-in hybrid sports activities automotive needed to make do with a three-cylinder engine. Sure, the tiny-but-mighty B38 from MINIs and BMW’s smallest automobiles. It’s been six years for the reason that final i8 was constructed, and now a mad genius is doing the unthinkable: a B58 engine swap. Trevor from Bimmer Community is trying to shoehorn a six-cylinder into Munich’s radical sports activities automotive.

The inline-six comes from a crashed 2017 M340i xDrive donor automotive, and that is the place the story takes an fascinating twist. The turbocharged 3.0-liter unit shall be crammed underneath the hood, the place BMW by no means supposed to mount a combustion engine. That’s solely doable by eradicating the front-mounted electrical motor, which is already out of the automotive.

This Frankenstein i8 has already shed its battery pack. Moreover, the tiny 1.5-liter gasoline engine can also be gone to make room for the brand new {hardware}. Nevertheless, marrying the M340i’s oily bits to the i8 requires new subframes. These must be custom-made for this wild construct. The unique entrance and rear subframes have already been eliminated, following BMW’s service bulletin.

The primary query on everybody’s thoughts is: Will the B58 match? Stuffing the M340i’s {hardware} right into a automotive that after housed a mid-mounted battery and a rear-mounted gasoline engine sounds extremely difficult given the packaging constraints. The six-cylinder is predicted to sit down proper above the entrance axle. The transmission and switch case will occupy the house the place the hybrid battery was.

Assuming the undertaking involves fruition, one has to marvel how mounting an inline-six up entrance will have an effect on weight stability, and, by extension, dealing with. Trevor is hopeful the distribution gained’t change drastically in comparison with the unique i8, because the radiators and auxiliary cooling elements shall be positioned on the rear.

Ideally, this bonkers i8 will produce round 700 horsepower on the wheels. We’ll definitely be watching how the construct progresses within the coming weeks. The concept of a non-electrified i8 with a bigger engine stays intriguing even years after manufacturing ended. Putting the B58 up entrance is unconventional, however then once more, the i8 was all the time a vastly advanced automotive constructed round a plug-in hybrid setup with a small rear-mounted ICE and a entrance electrical motor.
