The BMW 600 is a four-seat microcar produced by BMW from mid-1957 until November 1959. Partially based on the BMW Isetta two-seater, it was BMW's first postwar four seat economy car. It was not a sales success, but it began the design process for its more successful successor, the BMW 700. ==Concept, design, and engineering== BMW needed to expand its model range, but they did not have the resources to develop an all-new car with an all-new engine. Therefore, it used the Isetta as starting point for a new four seat economy car. As a result, the 600 used the front suspension and front door of the Isetta. The need to carry four people required a longer frame, a different rear suspension, and a larger engine. A new perimeter frame was designed, using box section side members and straight tube crossmembers. The rear suspension was an independent semi trailing arm design; this was the first time BMW had used this system. The chassis had a wheelbase of , a front track of , and a rear track of . The 600 was powered by the flat-twin engine from the R67 motorcycle/sidecar combination. This engine, which delivered at 4,500 revolutions per minute, was mounted behind the rear wheels. A four-speed manual gearbox was standard, while a Saxomat semi-automatic transmission was available. The 600 had a top speed of approximately 100 km/h. Access to the rear seats was by a conventional door on the right side of the vehicle. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「BMW 600」の詳細全文を読む スポンサード リンク
