BMW E21 is the body designation for the first BMW 3 Series compact executive car, produced by the German automaker BMW from 1975 to 1983. This series was the immediate successor to the BMW 2002 and was superseded by the BMW E30. ==Development and early history== Under the direction of its 51% percent shareholder, Herbert Quandt, BMW decided upon a replacement for their aging 2002. Without it, there was the distinct possibility of BMW leaving its core mission of building driver oriented cars, and alienating an existing customer base long enamored with the company's 2002 model. Paul Bracq, Director of Design at BMW from 1970 to 1974, is credited with setting the design direction of the E21 3 Series, while Wilhelm Hofmeister is credited with first drawing the small forward wedge at the base of the C-pillar, a strong design trait of the first Three-series. In July 1975, BMW’s Board of Management first presented this new model series in the Munich Olympic Stadium for public appraisal. The frontal view of the new car was dominated by the BMW trademark kidney grille standing out clearly from the radiator cover. The styling of the new car bore a resemblance to the BMW E12 5 Series. The wedge shape of the two-door model was distinctive, extending all the way to the unusually high rear end. In response to criticism of the tail design, a black plastic trim panel between the tail lights was added. The car's styling was otherwise well received. Measuring 4355 millimeters (171.5 inches) in length, 1610 millimeters (63.4 inches) in width, and 1380 millimeters (54.3 inches) in height, the E21 Series continued the tradition of the New Class. With the wheelbase measuring 2563 millimeters (100.9 in), there was little body overhang in the rear-wheel-drive design. The track measured 1364 millimeters (53.7 in) at the front, and 1377 millimeters (54.2 in) at the rear. The suspension incorporated rack and pinion steering and MacPherson strut suspension at the front, and semi-trailing arm type independent suspension at the rear. The power assisted brakes were discs on the front wheels, while the rear wheels had drum brakes. Initially, a Getrag four-speed manual was the standard transmission fitment. Five-speed overdrive Getrag gearboxes were fitted as standard in 1980, but close ratio 'sport' gearboxes were available at the car's release as an option. Alternatively, purchasers could opt for the ZF 3 HP-22 three-speed automatic transmission. The cockpit design of the E21 marked the introduction of a new design concept, with the center console and central dashboard area angled towards the driver. This feature has become part of BMW’s interior design philosophy for many years. As a sign of passive safety, all edges and control elements within the interior were rounded off and padded. At the E21's release, three models were available: with 316 (1.6-litre), 318 (1.8-litre) and 320 (2.0-litre) versions of the BMW M10 four-cylinder engine. To draw clear visual distinction within the new model series, the 320 models came with dual headlights, while the 315 - 316 and 318 had single round headlights. At the end of 1975, the 320i was introduced; the engine was fitted with Bosch K Jetronic fuel injection, delivering on premium grade gasoline. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「BMW 3 Series (E21)」の詳細全文を読む スポンサード リンク
