But how does it fare in a race?
Ever since BMW switched from the formula of small, light, and sporty, the world has eagerly awaited the M2. It has the dimensions of an E46 M3 and packs a 365-horsepower punch via a turbocharged 3.0-liter straight-six engine. But there is a little-known competitor that may have some even more impressive performance metrics. The Mercedes A45 AMG has a 2.0-liter turbocharged four-banger, but despite the engine’s size handicap it makes 376 horsepower. This means that the Mercedes packs 188 horsepower per liter to the BMW’s 121.6.
