The body of E30 replaced the previous E21 which have become to a popular body of the small third BMW series in 1983. First E30 was more modifed E21, rather than absolutely new car and used generally the same engines. The main constructive changes concerned forward and back suspension brackets and salon ergonomics. However designers of firm so well worked over appearance that magnificent proportions of E30 still admire admirers of BMW, and style of this car began to be considered as the classical. On the other hand, since E30 the firm refused the front grille mown forward which were characteristic feature of all BMW cars throughout the previous 20 years. It caused some resonance in the ranks of adherents of BMW style. E30 body got something, but BMW something lost.
Updatings the versatile person and кабрио continued to be issued till 1993, but generally production E30 was stopped in 1991 as a result of change of a body of the 3rd series with E36.
E30 appeared for the first time in January, 1983 in the only option of a 2-door compartment. Only in a year, in January 1984 buyers have an opportunity a choice with the advent of a 4-door sedan that at once strongly increased popularity of model. In 1986 in sale the E30 cabriolet arrived. And only it is close by the production E30 end Bavarians pleased with the versatile person. However, the luggage compartment could not brag of considerable volume, but the car simply perfectly looked. Other rare updating – model 325iX with a full drive – borrowed transmission from all-wheel drive "five" in body Е34. Diesel updatings of a sedan were issued also.
Certainly, the most remarkable car in the 30th body is M3 of office of Motorsport for participation in the races FIA GT. This model passed a set of updatings and had 3 evolutionary versions to correspond to changing requirements of FIA. At the same time M3 was and on wide sale. The model was fantastically successful, constantly occupied the top lines of tables. Paying tribute fine qualities of E30, it is necessary to notice nevertheless that for M3 Motorsport it was compelled to make a special suspension bracket, on a design similar to the fifth series (E28 body).
In the middle of 1987 the body underwent easy cosmetic changes. The front grille was slightly lowered, chromeplated a bumper were replaced more fashionable black (and subsequently and painted in color of the car), the size of back lamps increased. Practically all cars after 1987 have the power steering (an exception – 318 with the carburetor) and much softer pedal of an accelerator.
The specific mention is deserved by the model 325iS which was issued in 1989-90. On it the new "pyateroshny" six-cylinder M50 engine with volume 2.5 liters, 24 klapanamiya in capacity of 192 h.p. is established. The car was completed with special plastic spoilers, bumpers and thresholds, a suspension bracket from M3 and sports salon.
In only 9 years of production more than 2.2 million E30 were let out.
First the younger E30 models used the old four-cylinder M10 engine put for 2002 and E21. Then M10 was laid off and replaced in 1987 with M40 with a new injector and bigger capacity. But emergence in 1989 of updating of M40 with the M42 code became a real miracle. This engine with two cam-shafts and 24 valves could compete on capacity to big M30 engines, squeezing out 140 h.p. from the same 1800 cubes and possessing unprecedented before dynamism of M42 held on in production already till 1996.
The majority of the senior E30 models (320i, 323i, 325i) used the remarkable six-cylinder M20 engine, dividing it with "pyaterka" of the same years. Including was issued (only in the USA) and economic model 325e with low-turnaround 2.7-liter M20/B27eta. However on late 325iS there was new M50 with 24 valves. The rare South African model 333i used the M30 "big six" engine from 5/6/7 series. Cars with the diesel M21 engine (6 cylinders, 2.4 liters) with a turbo-supercharging and also were issued without.
Disk back brakes were put only on 318iS, all 325 models and on M3. ABS was standardly established only on 325e, 325iS and on M3. Optionally was present on late releases of models 320i, 325i and 333i. Some senior models (325, M3) are equipped with antiprobuksovochny system (differential with a limited proskalzyvaniye) with factor of 25 %. For check: number of such differential comes to an end with the letter 'Z'.
