Build a new BMW 328 off the Z4 and what do you get? Bavarian retro: the 328 Mille Miglia Touring Coupe introduced at the Mille Miglia historic rally in Italy. An original 328 Mille Miglia Touring Coupe won the race in 1940, so BMW built a new one to commemorate 22 vintage Bimmer racers that competed in this year's event. That 1940 BMW set a record the company says survives today, running the 1000-mile race at an average of nearly 104 mph. The concept is based on the new Z4 M Coupe, with 330 horses from its 3.2-liter I-6. It's slightly longer and lower than the Z4 Coupe, with 245/40 tires on 20-inch wheels. The touring coupe has a hinged roof for entry and exit and apparently no iDrive system.
