Production of the new BMW Z4 is scheduled to begin before the end of this year at Magna Steyr's facility in Graz, Austria. A contract assembler, Magna Steyr, already builds the Mercedes-Benz G-Class, Jaguar I-Pace and E-Pace and BMW 5 Series at its Graz plant.

BMW has not been quiet about the fact that the new Z4 is on the way, showing us a camouflaged prototype of the roadster being put through its paces on a test track in France. While other models are also likely to be offered, the prototype was the Z4 M40i, and packed a turbocharged inline-six engine, M Sport brakes, adaptive suspension and an electronically controlled differential. BMW had previously given us a hint as to the Z4's styling direction when a concept was shown last August in Pebble Beach.
