Even though the BMW M2 was touted as the purest of the current BMW M car crop, it lacked a few key elements to make it perfect - namely, an 'S' engine. Almost all BMW M cars throughout history have been powered by a bespoke engine starting with the letter 'S' but the standard M2 used a modified version of the N55 inline-six found in other non-M BMW models. When BMW introduced the M2 Competition, it dropped in the more potent S55 engine from the current M3/M4 and significantly increased power output.
The old M2's N55 twin-scroll 3.0-liter inline-six produced 365 horsepower and 343 lb-ft of torque but the new twin-turbo S55 inline-six produces a whopping 405 hp and 406 lb-ft. This massive increase in power (as well as a few other upgrades) . With an increase of 35 hp and 63 lb-ft of torque, you might expect the Competition model to be significantly faster than the base M2.
As it turns out, the Competition model is only marginally faster at best. In a , the M2 Competition with the DCT managed to hit 60 mph in four seconds flat (the same as the base M2). The car did complete the quarter-mile in 12.4 seconds at 116 mph, which was a tenth of a second quicker and three mph faster than the base car.
We know the Competition model is a but few people will ever take their car there to notice a difference. Even though the Competition model isn't much faster out of the box, it should accept more power on the aftermarket due to its twin-turbo setup. So if you are the type of person who likes to tune your car, the M2 Competition may be worth the upgrade.
