If there was an award for the favorite car among aftermarket tuners for the year, the BMW M2 makes a strong case. You might even say it makes the best case. This year alone, a number of the world’s best aftermarket companies have developed programs for the baby M sports coupe, including AC Schnitzer, G-Power, and Alpha-N Performance, among others. Now you can add Hamann to that list, and considering the tuner’s expertise in building kits for a wide variety of performance models, picking which M2 program is the best of them all just got a lot harder. For its part, Hamann’s new kit for the M2 follows the traditional blueprint of a Hamann program. It’s got a flashy exterior that’s characterized by the new wheels. It’s got technical upgrades to help the car in top working condition. Best of all, it’s got an engine upgrade that boasts an increase in output to 414 horsepower and 391 pound-feet of torque.
