It had 12 years of production glory, from 1977 to 1989 (U.S.), and its design was imitated by many others but never equaled--not even by BMW. Diehard 6er owners often refuse to buy newer models, instead pouring thousands into mechanical and cosmetic work to keep the big coupes cruising. 1980-84: 633csi The significant revisions BMW brought to the E24 for the 1980 model were all overshadowed by the wonders of Robert Bosch innovations. Using Bosch's ingenious new invention, the oxygen sensor, allowed efficient use of a three-way catalytic converter. The positively horrible and universally hated thermal reactor and EGR emissions control systems were dispensed with at once in favor of this new technology. A new factory electronic ignition system also appeared. The darkest chapter in U.S.-spec BMW engine history was finally at an end. While actual power output remained the same, driveability was immeasurably improved. More importantly, but unbeknownst to us at the time, electronic engine management systems would eventually allow U.S-spec BMW engines to achieve nearly the same power output as rest-of-the-world variants. It would take nearly 10 years, but the course was set in 1980. In 1983-84, Bosch Motronic engine management quietly entered our lives with Motronic version 1.0 basic. Ignition timing and fuel mixture were now computer-controlled. This early Motronic system, wonderful as it was at the time, is less than desirable today from a performance-tuning standpoint. No chips are available to upgrade the ECU--what you have is what you have. Even though the engines will still respond well to high-compression pistons and camshaft upgrades, electronic optimization is not possible. Similarly, while the catalytic converter is far preferable to the dreaded thermal reactor (writer looks down, spits), the exhaust system on these pre-1985 Motronic cars is incredibly restrictive forward of the cat. The end result was lots of header installations and de-catting prior to that becoming bad juju, and later, installation of 3.5-liter engines with advanced Motronics. A five-speed manual gearbox backed up the newly invigorated engine, but, contrary to popular close-ratio European fashion, fifth gear was overdriven to reduce engine speeds at cruising velocities. This allowed both increased fuel economy and use of lower (numerically higher) differential ratios to aid acceleration. Traditionally, BMW gears down cars when it wants to spiff up low-end zoot either as a result of engine size, automatic transmission or, in this case, emission controls. The automatic transmission option included cruise control starting in 1982.
