The BMW E23 was produced from 1977 to 1987. This car introduced many electronic features for the first time in a BMW, such as an on-board computer, service interval indicator, complex climate control systems, a check control panel and a dictaphone. It was also the first BMW that offered ABS, a drivers airbag and a new design of the front suspension.
From the beginning on you could order your BMW with 6 cylinder engines. From 1983 to 1986 you could order turbocharged 6-cylinder engines.
