The BMW 600 is a four-seater microcar produced by the German automaker BMW from mid-1957 until November 1959. Partially based on the BMW Isetta two-seater, it was BMW’s first postwar four-seater economy car.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. The chassis had a wheelbase of 1,700 millimetres , a front track of 1,220 millimetres, and a rear track of 1,160 millimetres.
The 600 was powered by the 582 cc flat-twin engine from the R67 motorcycle/sidecar combination. This engine, which delivered 19.5 horsepower (14.5 kW) 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./wikipedia
