The Opel 1.8 Liter is a family car manufactured by Opel. Production commenced in January 1931, and continued till November 1933. The Opel 1.8 Liter was the first new Opel to be launched following the purchase of an 80% share in Opel by General Motors (GM), and the first Opel to have been designed and developed by GM in North America.[1]
The 1.8-litre has been seen as a replacement for the Opel 4/40 which had gone out of the production in September 1930, although in terms of advertised performance the new model was less powerful and, as launched, a little slower than the older car as well as being approximately 300 kg lighter.
