Some childhood memories shape the way we see the world, and for me, stepping inside a BMW E23 for the first time was one of those moments. It belonged to our neighbor—an elegant, commanding presence I had only seen in car magazines. Seeing it in person was surreal.
My father’s Land Cruiser was a tough, go-anywhere machine, and my mother’s Volvo 240 was a tank of practicality, but the E23? Even though it was a used BMW 7 series, at least a decade old at the time, it still felt like something entirely different.
I still remember the weight of the doors, how the dashboard wrapped around the driver like a cockpit, and the way it glided down the road with effortless grace. Even as a kid, I could tell this car was engineered to a different standard. That was the day I understood what made a BMW special—and that feeling never left me.
The E23: A Game Changer for BMW
Introduced in 1977, the E23 was BMW’s first 7-Series, replacing the earlier E3 luxury sedans. Production continued until June 1986, although U.S. model-year listings extended into 1987. The E23 shared its technical foundation with BMW’s contemporary 6-Series coupe and adopted styling influenced by designer Paul Bracq.
Its long hood, distinctive kidney grille, restrained bodywork, and driver-oriented interior established a design philosophy that would influence BMW’s flagship sedans for decades. Unlike some competitors, BMW offered the E23 exclusively as a four-door sedan. There was no factory long-wheelbase derivative or V8-powered version.
Instead, the entire range relied on variations of BMW’s inline-six engine architecture.
BMW E23 Models and Engines
| Model | Engine | Market |
|---|---|---|
| 728 / 728i | 2.8L M30 inline-six | Primarily Europe and other international markets |
| 730 | 3.0L carbureted M30 inline-six | International markets |
| 732i | 3.2L fuel-injected M30 inline-six | Primarily Europe and other international markets |
| 733i | 3.2L fuel-injected M30 inline-six | Europe and North America |
| 735i | 3.4/3.5L-class M30 inline-six | Europe and North America |
| 745i | Turbocharged 3.2L or 3.4L inline-six | Selected international markets |
The naturally aspirated 730 from my childhood was one of the original European-market configurations. It used a carbureted 3.0-liter M30 engine rather than the fuel-injected powertrains that became increasingly common later in the E23’s production.
For American buyers, the principal E23 models were the 733i, followed by the 735i and the luxury-oriented L7. The turbocharged 745i was not officially offered in the United States, although imported examples exist.
Technology That Was Advanced for Its Time
Despite its conventional mechanical design, the E23 introduced important electronic innovations. The 1979 BMW 732i pioneered Bosch Motronic, integrating fuel injection and ignition control into a single digital engine-management system.
Depending on the model year, the E23 also offered ABS, onboard computers, electronic check-control, and advanced climate control.
Driving Experience: How It Stacks Up Today
By modern standards, the E23 is not a fast car, but what it lacks in outright performance, it makes up for in driving feel. The steering is communicative, the suspension is firm but compliant, and the inline-six engines, though not particularly powerful by today’s standards, deliver a smooth and predictable surge of power. Compared to its contemporaries—such as the Mercedes-Benz W126 S-Class—it feels much more engaging, staying true to BMW’s driver-centric philosophy.
However, it is not without flaws. The E23 was notorious for electrical gremlins, and as with most classic BMWs, rust is a constant concern. Parts availability can be challenging for certain trim-specific components, though the M30 engine itself is well-supported within the BMW community.
Does It Still Matters Today
For enthusiasts, the E23 represents the genesis of the 7-Series—a lineage that has gone on to define BMW’s flagship luxury segment. Unlike later 7-Series models that became increasingly complex and burdened with technology, the E23 remains relatively simple, retaining the mechanical purity that made classic BMWs so special.
If you’re considering an E23 today, it’s essential to seek one with a well-documented history, preferably from a dry climate. Avoid neglected examples, as restoration costs can quickly spiral out of control. But for those who appreciate classic BMW engineering, the E23 remains one of the most rewarding vintage luxury sedans to own.
BMW’s first 7-Series was a statement of intent—a declaration that luxury and driving pleasure were not mutually exclusive. It may not have the digital wizardry of modern 7-Series models, but the E23 remains a masterpiece of old-school BMW craftsmanship.
