In an effort to freshen an aging albeit pretty design, BMW introduced its E24 6 Series and 7 Series cars to
replace the 3.0CS and 3.0S/Bavaria in the U.S. in 1977. The 6 Series, led by the 630CSi, was a coupe
while the 7 Series 730i was the flagship sedan version.
Designed by Paul Bracq, the 6 Series was handsome and stately, while the 7 Series expertly echoed the
6’s design, only with four doors. Unfortunately, both the 6 and 7 Series used low compression heads with air
injection, exhaust gas recirculation (EGR), and thermal reactors to meet U.S. emissions regulations, which
meant the cars were markedly slower than the European models. The EGR and thermal reactors also
produced more heat than the 3.0-liter, 176-hp six-cylinder engines could handle, which caused cracked
cylinder head and warping.
Beginning in 1980, BMW introduced a Bosch oxygen sensor and a catalytic converter, which solved the
car’s heat problems. In 1983, Bosch L-Jetronic injection was switched to Motronic, which was much more
efficient.. In 1984, the 6 and 7 Series received the option of a manual Getrag 5-speed transmission.
In 1985, the engine size was increased to 3.4 liters and the models were renamed the 635CSi and 735i
respectively. The boost in displacement resulted in 6 more hp and 19 lb-ft of additional torque. A front air
dam made the cars look sportier, and more equipment became standard. Both Series were available as
the more luxurious L6 and L7, as well.
The most desirable 6 Series was the M6, produced in 1988 and 1989. The car used a 256-hp version of the
635’s engine, and was only available with the 5-speed. The car retained much of the comfort of the standard
6, but became a high-line performer as well.
Neglected E24 6 Series and 7 Series are easy to find, as their well-equipped and sophisticated set-up
meant that standard repairs were often expensive. Today these cars are best to be avoided, as they will
ultimately cost more in the long run. Earlier cars, due to their EGRs and thermal reactors, are usually last on
the list for enthusiasts, while a good M6 is a fun and affordable businessman’s express. The later 3.5-liter
cars with 5-speed are also interesting and distinctive transport. As with any older car, be mindful of rust, and
check with a mechanic before spending more than you can afford to lose.
