Spy photos of a mystery BMW M8 mule being tested at the Nürburgring could be our first glance at BMW’s rumored 600-horsepower plug-in hybrid. The demise of BMW’s mid-engine i8 plug-in hybrid with no news of a direct replacement led us to wonder what BMW really has in store for the future of the formula, but if this early prototype is anything to go on, it may be alive and well. We’re not sure what BMW plans to call its next round of all-electric and plug-in variants, but whatever it ends up being called, the prospect is certainly fascinating.
Let’s start with what we’re looking at. At first glance, this appears to be a fairly run-of-the-mill BMW M8 with some camouflage over the front and rear, which is about what you’d expect to see from a company that is likely developing alternative bodywork for a mid-cycle update or a new appearance package. Looking more closely, however, we see the strategic tinting of the rear window glass along with very obvious air intake vents where the rear side windows should be. Translation? There’s something back there that 1) needs air flow and 2) BMW doesn’t want us to see.
To further grease the skids, our spies tell us that the engine in this car did not sound anything like the V8 found under the hood of either the BMW M8 or its racing variant, the M8 GTE, which carries over the former’s front-engine layout. In fact, the spy even referred to the sound as “different,” which could just be good salesmanship, but the fact of the matter remains that whatever is under there, it’s not from an M8, or any other 8 Series derivative currently known to us.
Conveniently, all of the things that make this an unlikely M8 variant, from the mid-engine layout to the unconventional exhaust note, make a compelling case for it as a revival of BMW’s plug-in flagship. Even the wheels appear strikingly similar to those on the BMW Vision M Next concept the company showed at Frankfurt last year, which was said to be a plug-in hybrid with a turbocharged four-cylinder gasoline engine making 600 horsepower. BMW claimed it could do 0-62 mph in 3.0 seconds with a top speed of 186 mph and boasting 62 miles of all-electric range.
