BMW’s powered-up open-top retort to the Mercedes-Benz SLK55 AMG and Porsche Boxster S, the Z4 M roadster gets the same 3.2-liter inline- six engine as the soon-to-be-discontinued fourth-generation M3. Sitting up front in the new car’s distinctive shark-like nose, the high-strung alloy block unit produces 343 hp at 7900 rpm—a solid 78 hp more than the 3.0-liter I6 in the facelifted Z4 3.0i. It is also 43 hp more than the 3.3-liter I6 Roadster S offered by Alpina, which up until now was the fastest Z4 offered through official BMW channels. Look for the same powerplant in the M version of the Z4 Coupe when it arrives in 2007.
