While we can't tell much about what visual changes lie beneath this car's camouflage, it does prompt some questions about the purpose of this car. It would seem a bit early for a mid-cycle refresh because, as previously mentioned, the M2 has barely been on sale for a year. In addition, with the exception of the front fascia, most of the car is uncovered. All of this leads us to believe that BMW may be working on an extra-hot version of the current M2.
Our spy photographer suggests that a higher-performance M2 could use a version of the twin-turbocharged inline-six found in the M3 and M4. It would certainly be an easy way to add power by using an existing powerplant. However, BMW could also achieve the goal of a more potent M2 by making it lighter and providing upgraded suspension and brakes. We bet it could even squeeze out a bit more power from the standard single-turbo inline-6.
