So far, all we’ve heard about the upcoming BMW M4 Coupe have been rumors, but now the vehicle has finally been caught testing for the first time. As you surely know by now, the upcoming BMW 3-Series will only include the sedan and station wagon models, while the coupe and convertible will be sold as the 4-Series. This means that the M3 will only be offered as a sedan, and if you want to buy a performance coupe or a convertible, you’ll have to buy the M4 .
When compared to a standard 4-Series Coupe , the M4 version will get the usual M-design elements like the front bumper, LED headlights, a wide track, different side air intakes, a sports exhaust system, and larger wheels.
Under the hood, the model will be rid of the current V8 found in the M3 and will benefit from a twin-turbocharged inline-six engine that will deliver about 450 HP. This will make the upcoming M4 both more powerful, as well as more fuel efficient than the current M3 Coupe.
