BMW 540

The year 1993 was spectacular in that BMW added a 4.0 liter V8 to the 5 Series lineup. This model was offered in both sedan and touring models although the latter was sadly not available in the United States. The 540 came equipped with a large, torque engine, upgraded brakes, and optional 6-speed transmission, which obviously made it a very competitive car in the sports sedan market. The 540i shared the M60 engine with the 530i, which used Nikasil bore linings. Unfortunately, this made both vulnerable to premature engine wear, as high sulfur content in some fuels resulted in deterioration of the linings. This was obviously a huge problem for BMW and they sought to rectify the problem as quickly as possible. They immediately introduced Alusil linings for this engine, which thankfully solved the problem. True BMW fans will know that a rare 540i M-Sport model was built in 1995, which included not just a firmer suspension and sport seats, but used many parts from the M5, except for the engine and transmission. A very limited 200 "Sport" models were built, with 135 of them containing a 6-speed manual transmission. Canadians were also privy to a rare model of their own. An M540i, which was similar to the American 540i Sport but with even more M5 parts, such as 345 mm floating front rotors, 18 inch wheels, and various trim pieces was released to the Canadian market only. This model is even more in demand with only 32 of these cars ever being built. All 32 vehicles were manufactured with a manual transmission. All of the 540is released had the same 0-60 mph time of 6.4 seconds, and could get 14-17 miles per gallon city (which in reality would be problematic with the rising cost of fuel today) and 23-29 mpg highway. Needless to say though, the car was well received by both drivers and automotive reviewers.
