Английская Википедия:BMW 600
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. 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.Шаблон:Sfn
As a result, the 600 used the front suspension and front door of the Isetta.Шаблон:Sfn 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.Шаблон:Sfn The rear suspension was an independent semi trailing arm design; this was the first time BMW had used this system.Шаблон:SfnШаблон:Sfn The chassis had a wheelbase of Шаблон:Convert,Шаблон:Sfn a front track of Шаблон:Convert, and a rear track of Шаблон:Convert.Шаблон:Sfn
The 600 was powered by the Шаблон:Convert flat-twin engine from the R67 motorcycle/sidecar combination. This engine, which delivered Шаблон:Cvt at 4,500 revolutions per minute, was mounted behind the rear wheels. A four-speed manual gearbox was standard,Шаблон:Sfn while a Saxomat semi-automatic transmission was available.Шаблон:Sfn The 600 had a top speed of approximately 100 km/h.Шаблон:Sfn
Access to the rear seats was by a conventional door on the right side of the vehicle.Шаблон:SfnШаблон:Sfn United States market cars are equipped with larger, sealed-beam headlights, and large bumper overriders.
Reception
The sales figures for the 600 did not meet BMW's expectations. During production from August 1957 to 1959, about 35,000 were built. This is attributed in part to competition with more conventional cars, including the Volkswagen Beetle.Шаблон:SfnШаблон:Sfn The Isetta, bubble car image also hampered sales of this larger, more upscale car.Шаблон:Sfn
Legacy
The 600 played a direct role in the design of its successor, the BMW 700. Wolfgang Denzel, the distributor of BMW cars in Austria, commissioned Giovanni Michelotti to prepare concept sketches based on a lengthened BMW 600 chassis. Denzel presented the concept, a 2-door coupe with a slanted roof, to BMW's management. The concept was generally well received, but objections were raised about the limited passenger space. BMW decided to produce two versions, the coupe, and a 2-door sedan with a taller, longer roof.Шаблон:SfnШаблон:Sfn
Another legacy of the 600 was its independent semi-trailing arm rear suspension. This was BMW's first use of this suspension system and, with the exception of the BMW M1,Шаблон:Sfn it was used on every BMW production automobile until the 1990s.Шаблон:SfnШаблон:Sfn It was eventually supplanted by the "Z-axle" multi-link suspension, first introduced with the BMW Z1 in 1988.Шаблон:Sfn The last BMW cars with semi-trailing arm suspension were the BMW Compact and the BMW Z3.Шаблон:Sfn
Space efficiency
The BMW 600 was noted in magazine and journal articles as an example of space efficient design.Шаблон:SfnШаблон:Sfn It was noted for carrying four people within a shorter length than that of the Mini.Шаблон:Sfn
