The latest-generation of the BMW M5 is the most high-performance iteration of the car yet. Perhaps the most unique thing about it though is the engine – it has a V10 engine in place of a traditional V-6 or V-8. That’s something most people (aside from us car enthusiasts, of course) probably don’t know about it. Does it matter that the M5 has two more cylinders than everyone else?

Apparently not. A new report out by Edmunds’ Inside Line says that the M5 could be shedding that engine for a V-8 powerplant.

The report flies in the face of a previous one we heard about the M5 in June. That one said that the M5 would be getting more outrageous than ever, utilizing not just the same naturally-aspirated 5.0-liter V-10 in the current car, but a twin-turbocharged one. Crazy? Oh yes.

That never seemed like the likeliest course of action, but it was always good to dream right? A turbocharged V-8 in the new M5 should ensure that power doesn’t suffer. BMW executives haven’t confirmed which V-8 will find it’s way into the M5′s engine bay, but the likeliest engine will be the 4.4-liter unit in the X5M and X6M. Goodbye M5 V-10, we hardly knew ye!
