This unlikely duel pits what is arguably the world's best sports sedan, the BMW M3, against a dedicated sports car—the Corvette Grand Sport. But despite having to haul around a rear seat, this BMW is a solid matchup against the Vette. Under those hoods, both cars have V8s with over 400 hp. In each machine, rear-wheel drive puts the power down to the ground. And more to the point, these two overtly sporting machines cost about the same—$55,720 for the Vette, $59,975 for the M3. This pair occupies a performance-car sweet spot, because they offer near supercar speed for far less than exotic-car prices. Since the new Grand Sport has considerably upped the Corvette's game, let's see if it can unseat the Bavarian powerhouse.
