The BMW M6 GT3 is a racing car built by BMW Motorsport according to the FIA GT3 regulations . The base vehicle is the BMW M6 (F13) .
The BMW M6 GT3 replaced the Z4 GT3, which has been in use since 2010, as a racing car for the GT3 Group's customer sport . With the M6 as a basic vehicle BMW wanted to eradicate the main criticisms of its predecessor. The Roadster BMW Z4 was smaller than the vehicles of the competitors and the short wheelbase made for a difficult handling. In addition, no engines more than six cylinders were available for the production version of the Z4 , which was considered too low for racing use. Lacking a smaller coupe with V8 engine in the model range, BMW had to put on the big and heavy M6 (F13) , which brought far-reaching changes. The mass of the car was reduced from 1925 kg in the standard condition to 1300 kg for the racing use, the sitting position shifted backwards and centered and the transmission migrated to the rear axle for a better weight distribution.
In addition there are extensive aerodynamic changes and further adjustments to the racing operation.In the IMSA WeatherTech SportsCar Championship, the M6 GTLM also replaces the Z4 E89-based BMW Z4 GTE . The M6 GTLM-specific development program, run by BMW Team RLL, which included tests at the Daytona International Speedway and the Sebring International Raceway , began in November 2015.
