The design of the E31 was the work of Klaus Kapitza, whose vision brought forth a sleek, aerodynamic body with a low-slung profile and pop-up headlights, which contributed to its distinct and timeless appearance. The design also featured a drag coefficient of just 0.29, highlighting its advanced aerodynamic efficiency for the era.

Underneath its stylish exterior, the E31 housed several advanced technological features. One of the standout aspects was its use of Electronic Damping Control (EDC), an adaptive suspension system that adjusted shock absorber settings based on driving conditions and driver input, providing a blend of comfort and performance. It also featured Dynamic Stability Control (DSC), which was one of the early implementations of stability control systems aimed at maintaining control during aggressive driving. Additionally, the car had Servotronic Steering, offering variable levels of assistance depending on vehicle speed, enhancing both maneuverability and stability. The on-board computer, another advanced feature, provided drivers with a wealth of information including fuel consumption, range, and average speed, adding to the car’s sophistication.

The BMW 8-Series (E31) came in several models throughout its production run, each with distinct characteristics. The initial model, the 850i, later renamed the 850Ci, was launched in 1989 with a 5.0-liter M70 V12 engine producing 296 horsepower and 332 lb-ft of torque. This engine was paired with either a 4-speed automatic or a 6-speed manual transmission, allowing the car to accelerate from 0 to 60 mph in about 6.8 seconds.

In 1993, BMW introduced the 840Ci, which initially featured a 4.0-liter M60 V8 engine producing 282 horsepower and 295 lb-ft of torque. This engine was later replaced by a 4.4-liter M62 V8 in 1995, maintaining the same power output but with improved torque delivery and efficiency. The 840Ci was available with both 5-speed automatic and 6-speed manual transmissions, offering a balance of performance and luxury.

The pinnacle of the E31 lineup was the 850CSi, introduced in 1992. This model featured a 5.6-liter S70 V12 engine producing 375 horsepower and 406 lb-ft of torque, mated exclusively to a 6-speed manual transmission. The 850CSi was equipped with numerous performance upgrades, including a revised suspension, upgraded brakes, and a more aggressive body kit. This model could accelerate from 0 to 60 mph in about 5.6 seconds, making it the fastest and most desirable variant of the E31.

Production numbers for the E31 were relatively low, with a total of 30,621 units produced over its decade-long production run. The 850i/850Ci models accounted for 20,072 units, the 840Ci saw 7,618 units produced, and the high-performance 850CSi was the rarest with only 1,510 units built. These limited production numbers have contributed to the car’s desirability among collectors and enthusiasts today.

The BMW 8-Series (E31) faced competition from other luxury grand tourers of its time, including the Mercedes-Benz SL (R129), Porsche 928, Jaguar XJS, and Ferrari 456 GT. Each of these competitors brought their own blend of luxury, performance, and exclusivity to the market. The Mercedes-Benz SL was known for its blend of luxury and performance, the Porsche 928 for its handling and build quality, the Jaguar XJS for its style and comfort, and the Ferrari 456 GT for its high-end performance and exclusivity. However, the E31 stood out with its advanced technology, powerful engines, and the unique combination of luxury and performance in a grand touring package.

As of 2024, the market value of the BMW 8-Series (E31) varies significantly based on the model, condition, and mileage. Well-maintained 840Ci models typically range from $20,000 to $40,000. The 850i/850Ci models generally command prices between $30,000 and $50,000. The rare and highly sought-after 850CSi models are the most valuable, with pristine examples fetching between $80,000 and $150,000, with some even higher depending on their history and condition.
