BMW is planning to produce a high performance version of 1-Series M Coupe. The name of the project is 1-Series M Coupe GTS and it is inspired by by E36 LTW, E46 CSL and E92 GTS.
BMW 1M Coupe is expected to be powered by 3.0 liter inline six-cylinder twin-turbo engine with more than 340PS (250 kW) and 400Nm of torque.
However, the next 1M Coupe is already on the market. That is a little more than a year on the assembly line. So, nothing is mentioned about the release date of 1-Series M Coupe GTS.
