BMW Concept Coupe

BMW unveiled their latest concept in the run up to the contemporary Mille Miglia, a road race for cars that competed during the original event held between 1933 and 1957. The BMW 328 that set the fastest time in 1940, averaging over 100mph, has also provided inspiration for the Coupe Concept, which mixes the older car's silhouette with surfaces closer to the Z4 on which it is based. Powered by BMW's seminal 343PS engine, the car is wrapped with carbon-fibre reinforced plastic (CFRP), whose form is defined by designers using plaster rather than clay "for a closer emotional experience".
