New car will be based on M3 GTS
Details are scarce - and official info non-existent - but a thread on the BMW forum m3post.com suggests that the new car could be called the M3 GTS-R and that it will be a final hurrah for the current M3.
The GTS-R is expected to get all the features of the M3 GTS, including the adjustable carbon fibre rear spoiler and lightweight side windows, but adds a double-lip front spoiler pumped-up rear arches and a carbon fibre bonnet and rear boot lid.
The engine is likely to be the enlarged 444bhp 4.4-litre V8 from the GTS, and could possibly get the KERS regenerative braking and power boost system expected on the next-gen M5.
The GTS's striking orange paintwork won't be carried over, however; the GTS-R is said to be getting a matt black paint job.
