The BMW 3 Series E21, launched in 1975 and produced until 1983, marked the beginning of a legendary lineage. This first-generation 3 Series, fondly known as the "New Six," was a significant departure from its predecessor, the 1600/2000 series. The E21 introduced a distinctly sporty character, characterized by its compact dimensions, rear-wheel drive layout, and an emphasis on driver engagement. The design, penned by Paul Bracq, featured a clean and elegant profile, with sharp lines and a distinctive Hofmeister kink on the C-pillar, a hallmark of BMW's design language. The E21's lightweight construction, achieved through extensive use of steel and aluminum, contributed to its nimble handling and impressive performance. It offered a range of engines, from the frugal 1.6-liter four-cylinder to the potent 2.3-liter six-cylinder, providing a diverse palette for customers. The E21 became a cult classic in its own right, capturing the spirit of the "golden age" of sports sedans. It was a popular choice among drivers who sought a balance between everyday practicality and exhilarating driving experiences. The 3 Series E21's influence extended beyond its own generation, paving the way for the iconic status enjoyed by its successors. Its key features – a focus on driver involvement, sporty handling, and elegant design – became synonymous with the 3 Series model line. Today, the E21 remains a sought-after classic, appreciated for its timeless design, driving characteristics, and historical significance. The 1977 Service Repair Workshop Manual for the BMW 3 Series E21 serves as a valuable resource for owners and enthusiasts seeking to maintain and restore their prized possession, ensuring its legacy continues to thrive.
