The BMW 3 Series E21, produced from 1975 to 1983, was the first generation of the iconic BMW 3 Series, marking a significant departure from its predecessors and establishing the model line's enduring success. This compact executive car, affectionately nicknamed the "New Six," introduced a new platform, the E21, designed with a focus on driving dynamics and handling. It offered a range of petrol engines, starting with the 1.6-liter M10 unit and culminating in the high-performance 2.3-liter M20 engine powering the 323i. The E21 boasted a unibody construction, McPherson strut front suspension, and semi-trailing arm rear suspension, providing a balanced and nimble driving experience. It was available in both coupe and sedan body styles, further contributing to its appeal.

The E21 quickly gained a reputation for its performance and handling, becoming a favorite among enthusiasts. Its sporty character, combined with its practicality and relative affordability, helped cement its place in automotive history. The E21 also introduced several features that would become synonymous with BMW, such as the iconic kidney grille and the "Hofmeister kink" in the rear window line. While initially facing stiff competition from established rivals, the E21's unique combination of driving pleasure, style, and practicality solidified its position as a true BMW classic, laying the foundation for the 3 Series' remarkable success over the ensuing decades. The E21 remains a sought-after collectible for its historical significance, driving experience, and timeless design.
