Behold, the M8 Gran Coupe concept, the new halo car that will sit atop the BMW lineup someday. The M8 Gran Coupe concept follows hot on the heels of the 8 Series Coupe concept that debuted in late 2017. As is the trend, it's a "four-door coupe" version of that car, offering a bit more usability. Unlike that original two-door, the M8 Gran Coupe envisions a hotter M version of the eventual 8 Series Gran Coupe. While no mechanical information or performance data was given, you can bet the M8 Gran Coupe will be a blistering performer. In addition to this and the coupe, we expect BMW to debut a convertible version of the upcoming 8 Series, as well.
