The BMW 3 Series E21, launched in 1975, marked the beginning of a legendary lineage for the German automaker. This compact executive car, the first to wear the "3 Series" badge, was a departure from the large and luxurious sedans BMW had traditionally produced. The E21 aimed to offer a more affordable and sporty option, targeting a younger and more dynamic customer base. Built on a completely new platform with a focus on efficiency and agility, the E21 sported a characteristically sharp and elegant design, notably featuring a long hood, a low roofline, and a distinctive Hofmeister kink in the rear window. While its predecessor, the 2002, had established BMW's reputation for sporty driving, the E21 solidified it, offering an engaging experience with its precise steering, well-balanced handling, and responsive engine options. This combination of practicality and performance made the E21 a resounding success, becoming a popular choice among enthusiasts and everyday drivers alike.

The E21 featured a range of four-cylinder petrol engines, ranging from 1.6 liters to 2.3 liters in displacement. While the smaller engines offered decent fuel economy, it was the more powerful 2.0-liter and 2.3-liter variants that truly showcased the car's sporting spirit. The E21 also spawned a number of performance-focused versions like the 320i, 323i, and the iconic M1, showcasing the car's potential for thrilling driving dynamics. Production of the E21 ceased in 1983, making way for the all-new 3 Series E30. However, its legacy continues to inspire, influencing generations of BMW 3 Series models and solidifying its place as a legendary icon in automotive history. The E21 is often praised for its timeless design, engaging driving experience, and its status as a significant turning point in BMW's history, setting the stage for the brand's future success in the compact executive car segment.
