Even before the BMW M3 sedan and M4 coupe make their official debut, rumors are suggesting the M division is preparing a track-oriented two-seat variant of the M4 coupe to mark the company's 100th anniversary in 2016. The new high-performance model could weigh up to 220 pounds less than the standard M4, Australia's Motoring reports.
“For what we are planning, look more to the M3 GTS than the CSL," a BMW M source told Motoring. "We have concepts for a special model and this [the M4] will be the homologation basis.”
Where the standard M4 coupe has a carbon fiber roof and trunk lid, the lightweight model will replace the aluminum hood and front fenders with more carbon fiber. Aluminum doors will replace the steel units. Inside, the rear seats will be tossed and lightweight carbon fiber shell front seats with minimal padding will replace the power front seats. Alcantara will be used instead of leather. The track-oriented M4 coupe will only be offered with the six-speed manual, while the standard M4 coupe will be available with a six-speed manual or seven-speed dual-clutch transmission.
A hardcore CSL version is unlikely for the M4 coupe as it already uses a carbon fiber roof, thinner glass, less sound deadening, and lighter seat and wheels. For those wondering if carbon fiber techniques used in the i3 and i8 PHEV models could further enhance M cars, some of the technology from the i3 originated in the M division.
