BMW 635CSi

Properly cared for, the now-classic BMW 635Si is one of the German automaker's better vehicles. It had (and has) a great deal going for it. The BMW 635, built on the E24 platform, was powered by an inline six M30 engine, equipped with the Bosch L-Jetronic fuel injection system, generating 218 horsepower. That peppy motor was joined to either a three speed automatic transmission or the famous Getrag four speed manual, delivering power to the rear wheels with a 3.07:1 limited slip differential. The result was a road demon with a top speed of 140 miles an hour. And, just so the driver could bring it to a secure stop without worrying about overheating brakes, the 635 was equipped with four wheel ventilated brakes.

An early version, designated the 633, was introduced in Europe in 1976. However, Americans had to wait another year before the 6 Series arrived in domestic showrooms. The 635 itself finally came out in 1978, but only in Europe. In 1979, a BMW 635Si review speculated that when the the car finally made it into the U.S., "...little of the European car's fire and brimstone would be left."

Americans had to wait until 1985 before they could get behind the wheel of the 635Si. Meanwhile there were improvements made over subsequent model years, although these came slowly. In 1980, the manual transmission was upgraded to a close ratio five speed, along with an improved suspension system, ABS brakes and computer controlled ignition. Three years later, the ZF four speed automatic transmission was made available as an option.

The major revision came in 1985 when the older engine was replaced with the 3.4 liter Bosch Motronic. This engine featured the world's first adaptive engine system, offering a reliable alternative to that company's old L-Jetronic fuel injection system - which could be buggy at times. That was the year the BMW 635Si finally made it into U.S. dealerships. Unfortunately for performance buffs, it was a pale shadow of its European counterpart. The import version had an overdrive five speed and a lower compression, lower powered engine in order to comply with U.S. environmental and emissions regulations. That wasn't helped by the exhaust system and the mandatory catalytic converter, though some modifications were made to compensate for the higher back pressure.

In 1987, BMW was finally able to offer U.S. buyers a higher powered engine that was comparable to what European drivers enjoyed. However, by that time, the 635Si had lost some of its luster for American motoring enthusiasts. An automatic transmission and a number of luxury add-ons increased the vehicle's weight by a few hundred pounds. On the up side, there were some definite improvements made to the interior of the vehicle, including genuine leather upholstery, and BMW 635Si seats that were both heated and cooled.

Today, the major problem with the 80s-vintage car is finding a BMW 635Si that hasn't been neglected. Hopefully, it has been cared for and maintained, but if not, don't fear the usual inflated price tag usually attached to German auto parts.
