I posted it in the main forum, but I figured I'd give you guys the better version. As can be seen from these shots from Nürburgring, BMW is about to bring out a hot M version of the Z4. According to rumours, the Z4 M Roadster will make its debut at the January 2004 Detroit Motor Show, most likely featuring either a V-8 engine delivering 350 hp or an in-line six delivering 343 hp from the current M3. The Z4 M can be distinguished from the standard model by its big front skirt with large air intakes and four exhaust pipes. During the high-speed tests at Nürburgring, the pictured prototype is using different alloy wheels.
