The M8 Gran Coupe concept predicts the looks of the production car, which is launching in 2019. We expect the M8 to be available in all of the 8-series’ body styles, including two-door coupe and convertible, in addition to the four-door concept, and to be powered by a version of the M5’s twin-turbo V-8 that makes at least 600 hp and 553 lb-ft of torque. It should have an eight-speed automatic sending all that power to a rear-biased all-wheel-drive system.
Having seen the M8 Coupe and the standard 8 Series Gran Coupe, it’s pretty easy to imagine how the M8 Gran Coupe is going to be inside and out. BMW’s answer to the Mercedes-AMG GT Four-Door Coupe and the forthcoming Audi RS7 Sportback will likely be offered in regular and Competition flavors like its two-door 8er siblings. That means its twin-turbo 4.4-liter V8 engine will deliver as much as 617 horsepower in the hotter trim.
The M8 Gran Coupe, with its extra rear doors, will likely be a tad heavier than its coupe counterpart, but performance figures should be nearly identical. The M8 Gran Coupe will be able to accelerate from 0-60 mph in just 3.0 seconds, and carry on to an electronically limited top speed of 155 mph. If you opt for the aforementioned Competition package, that electronic nanny will be eliminated, allowing for a top speed close to 190 mph.
Look for the M8 Gran Coupe to land in BMW showrooms either later this year or in early 2020. Pricing hasn’t been confirmed, but expect the M8 GC, which will likely be branded as a 2021 model, to list from about $135,000.
