What the E31 Is and Its Place in BMW History
The BMW E31 is the chassis code for the original 8 Series, a pillarless grand touring coupe produced through the 1990s. Conceived as a technological showcase and a spiritual successor to the 6 Series (E24), the E31 pushed BMW into new territory with pop-up headlights, a wedge-shaped silhouette, and a level of electronic sophistication that was cutting-edge for its era. Rather than a straight sports car, the 8 Series was pitched as a continent-crossing luxury coupe, a role that defined its character and its enduring appeal among collectors.
The E31 arrived at a moment when BMW was demonstrating engineering ambition across the range, and its development reflected the same brand philosophy you can trace through the BMW DNA. It remains one of the most distinctive shapes ever to wear the roundel.
The Models and Body Styles
The E31 was offered exclusively as a two-door coupe, but the drivetrain lineup gave buyers meaningful variety:
- 850i / 850Ci — the V12-powered flagship that launched the range and defined its GT mission.
- 840Ci — a later V8 variant that delivered strong performance with lower running costs and lighter weight over the front axle.
- 850CSi — the sporting halo model, with a more powerful V12, revised suspension and subtle body enhancements, now among the most coveted E31 variants.
Every E31 shared the trademark frameless door glass and low, aerodynamic profile that made the 8 Series instantly recognizable.
Engines and Driving Character
The E31's V12 models used BMW's M70 family, later evolving into the enlarged S70/M73-derived units in higher-output guise, while the 840Ci adopted BMW's M62 V8. Both configurations emphasized smooth, effortless torque over outright revs, reinforcing the car's role as a refined long-distance cruiser. Manual gearboxes were available on some variants, though many buyers chose automatics that suited the relaxed GT temperament. The E31's era of V8 grand touring foreshadowed later luxury BMWs like the E52 Z8 and the V8 versions of the E53 X5.
Ownership, Collectibility and What to Know When Buying
The E31 has firmly entered classic-collectible status, and values for well-kept examples—especially the 850CSi and low-mileage V12 cars—have climbed steadily. Before buying, keep these points in mind:
- Electronics: the E31 packed advanced systems for its day, so verify that everything functions and that fault histories are documented.
- Maintenance cost: V12 service is complex and expensive; budget accordingly and favor cars with thorough records.
- Rust and body condition: inspect closely, as bodywork repairs are costly on this shape.
- Provenance: confirm the exact model and specification using our VIN decoder before purchase.
A sorted E31 rewards owners with rare presence and genuine grand-touring ability that few coupes of any era can match.
