The renderings below depict a 2-Series Gran Coupe sedan which would be BMW's answer to the A3 sedan and Mercedes CLA. BMW already announced they are planning a major model expansion which includes a 2-Series. The 2-Series would likely have derivatives such as a gran coupe in order to squeeze as many sales as possible out of the platform. Drivetrain options would likely mirror the F20 1-Series.
What would really be exciting is an M2 model which BMW is apparently considering with a tweaked N20 4-cylinder with an output of over 340 horses. Things are definitely going to get interesting next year and BimmerBoost will bring you more details on the platform as it develops.
