The BMW 320 was a car manufactured by BMW in Germany from 1937 to 1938, as the successor to the 319-based BMW 329. It was offered in 2-door saloon and convertible versions. Approximately 4,200 cars were made, of which 1,835 were cabriolets.
The car was first presented in July 1937. It showed a very similar resemblance to the 329. It was a high performance car with many admirers. The 320 was built on a shortened BMW 326 frame and used a 326 engine with a single carburettor and an output of 45 hp-metric. The 320 had a top speed of 65 mph. The suspension, which was carried over from the 329, consisted of an independent front suspension with a high-mounted transverse leaf spring acting as upper control arms and a conventional live axle on semi-elliptic springs at the rear. It had a slightly greater displacement 6-cylinder engine. It was available as a two-door sedan or two-door convertible and stayed until 1938. The BMW 320 was smaller, less expensive, and lighter than its predecessor. It offered easy handling and a balanced power-to-weight ratio.
The 320 was replaced by the BMW 321 in 1938.
