Since the moment it went on sale in 2014, there's been lots of speculation as to whether BMW will build an even more powerful version of its i8 hybrid sports car. Officials from its famed M division have repeatedly denied that the i8 will be sent their way. However, BMW's 100th anniversary is happening next year and a proper celebration will be in order. We're hearing there are a few projects in the works, and now, according to Auto Express, a more hardcore version of the i8 can be added to that list. But here's the thing: it won't be an M car.

An inside source told Auto Express that engineers from the "i" division are anxious to "showcase the capabilities of the i8's lightweight carbon fiber structure" as well as its plug-in hybrid drivetrain. Supposedly, the i8 can handle up to an additional 300 hp. Its drivetrain consists of a 1.5-liter three-cylinder gasoline engine and an electric motor with a combined output of 357 hp and 420 lb-ft of torque. Rumor has it that engineers are testing a 2.0-liter four-banger with over 300 hp, thus bringing total output to about 450 hp. To counteract the added weight of a larger engine, the car will feature unpainted carbon-fiber body panels and a stripped-out interior. A hardcore i8 does have a lot of potential and BMW has an ideal reason to build it.
