BMW's 3-Series: A Rise to Dominance
BMW's 3 Series, climbing from niche preference to market dominance.
The BMW 3-Series has been a force to reckon with since its debut in 1975, replacing the 02 models and setting the stage for BMW's lasting success. With over 20 million units sold, it's the world's best-selling premium midsize model, and the eighth generation is just about to drop. But let's rewind to the early days.
The Game Changer
Back in the day, debuting a new BMW model at the Munich Olympic Stadium was no ordinary affair. In 1975, that's exactly what they did with the 3-Series, the new entry-level model for the brand. It was just a number (3) and a new generation, but little did they know that they were about to ignite a success story that's still going strong. The 3-Series continued the allure of the disguised two-door 02 family sports car, introducing smooth-running inline six-cylinder engines in 1977, outpacing competitors like Alfa, Volvo, and even chasing popular sports cars such as the Porsche 924.
A Million in Six Years
The 3-Series was a star on and off the screen, appearing in crime shows like "Derrick" and "Tatort," strutting on streets like Ku'damm and Kurfürstenstraße, racing on touring tracks, and serving as a premium service vehicle. In just six years, the 315-323i models surpassed the one-million-unit mark, breaking records set by their 02 predecessors. That was the first peak of a bestseller career that continues to this day.
The Future Awaits
With the seventieth anniversary celebrations of the 3-Series just a memory, the stage is set for the eighth generation, scheduled to roll out in 2026. The i3, based on the new Neue Klasse architecture, will lead the way, followed by the updated 3 Series with conventional engines. The 3-Series is about to start its next chapter.
From Niche Player to Global Actor
Fast-forward half a century, and we see the 3-Series going from a niche player to a global actor. The first 3-Series, at 4.36 meters long, was 13 centimeters longer than the compact-looking 02 types. This imposing appearance suited the ambitions of BMW's CEO, who aimed to make BMW a global player with new models. The 3-Series not only broke production records for a BMW series but also saw CKD assembly of the bestseller on several continents.
Variety Is the Spice of Life
BMW didn't disappoint in offering a variety of options for the 3-Series. Just a single generation of the 3-Series had six body variants and ten engine options, including the first M3 and diesel. If you were into open-air driving, the 3-Series had you covered, with a five-seater cabrio based on coachbuilder Baur's conversions.
The Art of Speed
The 3-Series made art history in 1977, when pop art artist Roy Lichtenstein transformed a BMW 320i Turbo into an Art Car. This Group 5 racing car, adorned with "Benday-Dot" livery, finished ninth overall at Le Mans and gained cult status as BMW expanded its Art Car lineup with further 3-series generations.
A History of Success
Looking back, there are no flops among the previous seven generations of the 3-Series. Minor crises, such as quality issues with the E36 in the 1990s, were quickly resolved by the Bavarians, and they found answers to new rivals like the Mercedes 190 and C-Class, as well as the Audi A4, Volvo S60, and Lexus IS. Suv madness notwithstanding, the 3-Series remains one of the last globally coveted premium classics.
A Classic Car Champion
Expert Christoph Pichura of Classic Analytics explains the popularity of the E21 in the classic car community: "The E21 became the most important model line in the BMW group and had practically no competition until the mid-1980s. Apart from the Baur Topcabriolets, the individual versions differ only in the engine, as is typical for BMW, the 323i, the most powerful model, is still the most expensive variant today. At least 28,000 euros must be paid for a good example."
Milestones in Time
The E21 milestones include its launch in June 1975, with new production facilities at the Munich plant to accommodate customer-specific vehicles. In July, the first 3-Series BMW was presented at the Munich Olympic Stadium, with versions including 316, 318, 320, and 320i, all with four-cylinder engines. Harald Ertl won the German Racing Championship title with a Schnitzer BMW 320i Turbo in 1978, and a similarly turbocharged BMW 3 Series works car with a 1.4-liter engine and 410 PS was a precursor to the engine that would make Nelson Piquet the first Turbo World Champion in Formula 1 with Brabham BMW in 1983.
