It's also the closest thing in this generation of M3 to a CSL that we're likely to see (though you might argue that the GTS was that). 'CRT'-style models are part of the future of the M division, however, say our spies at the 'Ring, and we can even expect to see something like this on an M version of the new 6-series.
The 450hp engine is also taken over from the M3 GTS, and provides what you might call a generous 180mph top speed.
Just 67 cars will be built (that's 65 for customers, and 2 'press' cars), with 20-25 expected to come with the steering wheel on the right-hand side. And they'll be built at a price. If you want one, you'll have to part with around £115k for the privilege.
Cheers to Tony Hetherington for the info, we're not so sure about the quality of his pics... (only joking, Tony...)
