BMW 1800 Brochure

Introduced in September 1963, the BMW 1800 was the second member of the New Class family. This model had an M10 engine with a 84 mm (3.3 in) bore and 80 mm (3.1 in) stroke, giving a displacement of 1,773 cc. It produced 67 kW (90 hp) at 5,250 rpm and 130 N·m (96 lb·ft) at 3,000 rpm.

An automatic transmission option was introduced in 1966 and in 1967 the 1800 was generally updated along with the 2000. The updates included interior changes (a modernized dashboard design and simpler door panels) as well as styling changes to the front grilles.

In 1968 the 1,773 cc engine, used in the 1800, was replaced by an engine with the 89 mm (3.5 in) bore of the 2.0 L engine and the original 71 mm (2.8 in) stroke, which resulted in a displacement of 1,766 cc and a stroke/bore ratio of 0.798:1 (compared with the previous 1800 engine’s ratio of 0.952:1).
