According to reports, the joint BMW Toyota collaboration car that will replace the Z4 and may even relaunch the Supra name will be built in Austria, at a plant owned by third-party manufacturer Magna Steyr. BMW claims production will start in 2018, with the soft-top roadster coming off the line first, and the hybrid Toyota sports coupe following shortly thereafter. Annual production for both cars combined will be only 60,000 units, so listen very very carefully for pre-order details, but of course, we will keep you up to date.
