The BMW 3 Series E21 is a compact executive car that marked the beginning of the iconic 3 Series lineage for BMW. Introduced in 1975, the E21 was the first generation of the 3 Series and served as the successor to the 02 Series. It was the first BMW to be called the "3 Series," and its sleek, sporty design, coupled with rear-wheel drive and a range of powerful engines, established the blueprint for future generations of the 3 Series. The E21's design, penned by Paul Bracq, drew inspiration from the larger BMW 5 Series E12, but it was smaller and more agile. Its distinctive features included a sloping roofline, a distinctive front grille with four headlights, and a wide, low stance that emphasized its sporty character. The E21 was initially offered with a range of four-cylinder petrol engines, ranging from the 1.6-liter M10 engine in the 316 to the 2-liter M10 engine in the 320. A more powerful 320/6 model with a 2.0-liter six-cylinder engine was later introduced, along with a limited-edition 323i featuring a 2.3-liter six-cylinder engine. All models were paired with a four-speed manual transmission, and a five-speed manual became available later in the production run. The E21's success was due in no small part to its driving dynamics. Its excellent handling, precise steering, and responsive engines provided a rewarding driving experience. It was praised for its agility, sportiness, and overall driving satisfaction, further establishing BMW's growing reputation for building driver's cars.

The BMW 3 Series E21 remained in production until 1983, when it was replaced by the second-generation 3 Series, the E30. During its production run, the E21 enjoyed significant success and established itself as a popular and desirable sports saloon. It was also a competitive car in motorsport, particularly in touring car racing, where it achieved several notable victories. The E21's influence on the automotive landscape cannot be underestimated. It played a pivotal role in defining the compact luxury saloon segment and helped to solidify BMW's position as a manufacturer of premium, performance-oriented automobiles. Its legacy continues to inspire and influence car designers and enthusiasts alike, and the E21 remains a sought-after classic among BMW fans. Today, the E21 is a popular choice for classic car enthusiasts. It is praised for its timeless design, its engaging driving experience, and its relatively affordable price point.
