Driven: 2015 BMW M3 and M4

For many automotive enthusiasts, the BMW M3 has, for decades, been the gold standard by which all other sport coupes have been judged. Over the course of the seven year production run of the outgoing generation of the M3, denoted as the E90 (sedan), E92 (coupe) and E93 (convertible), the sports car landscape has changed fairly dramatically. Suddenly, $30,000 Mustangs were now capable of giving the M3 a run for its money both in a straight line and at the track, several new entries in the M3’s price bracket came out of the gate playing in leagues well above the M car’s performance envelope, and increasingly stringent government-mandated fuel economy standards began to force engineers to rethink their approach to vehicle and engine designs in fairly sweeping fashion. This new pair of cars, denoted as the F80 M3 sedan and the F82 M4 coupe, offer a new visual aesthetic, ditch the high-revving naturally aspirated V8 in favor of a torquey, twin turbocharged inline six cylinder and, for the first time in M history, bring a drop in curb weight when compared to its predecessor. There’s plenty of promising news there, but is all of it good? We headed to Elkhart Lake, Wisconsin, home of Road America racetrack and some genuinely great twisty backroads, to find out.
