E39 BMW five series is a generation of five series BMW cars manufactured between the years 1995 and 2003. Its predecessor is the E34 five series BMW from 1995. Starting from 2003, the E39 was also replaced by the E60. Sales of the five series started in 1995 to Germany and most western European countries first before expanding worldwide by the year 1996. In the year 2000, minor changes were introduced in a mid-generational facelift. The initial base model was the BMW 520i, which produced 112 kilowatts, about 150 horsepower, and later produced 126 kilowatts of power, about 170 horsepower in its later models. In 1998, the M5 variant was introduced, and it featured a 4.9L V8 engine -s62-. Apart from the M5 variant, all the BMW five series models were produced either as a saloon or as an estate car, which was called Touring.
The complete redesign of the car draws draws mainly from the seven series E38 in both style, construction and electronic technology. It featured style changes which were slight but cutting edge. The wheelbase, for example, was increased by 68 millimeters (about 2.7 inches) and its overall length was increased by 55 millimeters (about 2.2 inches) over its predecessor, the E34. The new E39 five series was made available in two forms in the United States: the 528i and the 540i. The 1996 model of the of the 528i brought with it a new M52 2.8L six cylinders inline, that it has in common with the three series 328i E36. And the 540i spotted a 4.4L V8 M62 which it shared with the seven series E38 740i. Both of these engines were upgraded over the previous generation of the five series. The 2.8L and six cylinder dual overhead camshaft generated 141 kilowatts (about 190 hp), compared to the the 4.4L V8 with dual overhead camshaft too, which generated 210 kilowatts (about 282 hp).
The 528i came with a standard five speed manual transmission, the “ZF S5-31“ which is a close-ratio gear system, and also with the option for a four speed automatic, the “A4S 310”. For the rest of the world, it came with a five speed step-tronic transmission, the “A5 S310Z” which was based on the “ZP 5HP18“. On the other hand, the 540i model came with the option of either the six speed Getrag manual transmission or the brand new five speed automatic, the “A5S 560Z”, which featured an adaptive transmission control system, and the step-tronic control here was optional. Other standard features on both models of the five series included dual front and side airbags, traction control, anti-lock brakes, air conditioning and power steering.
E39 Body Parts
The E39 offered good security for its occupants by featuring an all-steel framework, which was greatly improved in strength by using cutting edge computer based engineering methods. This system resulted in the reinforcement of critical points and an increase in rigidity without any significant addition of weight. A total of 10 kg (about 22 pounds) ended up being added anyway, which was offset by its light aluminium suspension. Also, high rigidity was achieved using laser welding. There was also focus and development in the area of structural dynamics. The body design was improved to enable bending and torsional twisting frequencies to exist above the natural frequency and in separate ranges. Having put these frequencies above the range of the driveline and engine vibrations, they do not get amplified and thus provide a very rigid monocoque.
E39 Steering and suspension parts
There are two steering types used in the E39, and the suspension system is a double pivot MacPherson strut system. In the 520i and 530i models of the E39, BMW utilised the rack and pinion steering, which was the first time in a five series. Due to its variable ratio, this system provides for a quicker steering response and a much more accurate feel. Also, to top it all, it made for a lighter weight. It steers from the anterior of the axle.
The e39 engines were in various configurations and quite different sizes. The specific model of the the vehicle determined its engine specifications, and there were plenty of models. For example, vehicles delivered to North America were the 525i, the 528i, the 530i, the 540i and the M5. And in Europe, there was however, a more diverse range, with BMWs offered in the 520i model, the 523i, the 525i, the 528i, the 530i, the 535i, the 540i and 525tds, the 525d and 530d, and the M5. There is also the 520d, which was the only four cylinder offering of the generation.
