Powertrain & Engine Architecture
The heart of the 840Ci is the M62B44 engine, a 4.4-liter naturally aspirated V8. This engine represented a significant upgrade over the earlier M60 and M62 engines, featuring individual throttle bodies, a revised intake manifold, and improved cylinder heads. The M62B44 utilizes a multi-port fuel injection system, delivering fuel directly to each cylinder for optimized combustion. The engine boasts a double overhead camshaft (DOHC) valvetrain, contributing to its high-revving nature and power output. The 6-speed manual transmission was standard, providing precise control and enhancing the driving experience. While an automatic transmission was available, the manual was favored by enthusiasts for its responsiveness.
Driving Characteristics
The 840Ci 4.4 offered a compelling blend of performance and comfort. The 286 horsepower and 309 lb-ft of torque provided brisk acceleration, with a 0-60 mph time of around 6.6 seconds. While not as brutally fast as the V12-powered 850i, the 840Ci felt more agile and responsive due to its lighter weight. The manual transmission allowed for precise gear selection, maximizing the engine’s power band. The gear ratios were well-chosen, providing strong acceleration in all gears. Compared to the automatic version, the manual offered a more engaging and connected driving experience. The suspension, tuned for grand touring, provided a comfortable ride while maintaining good body control.
Equipment & Trim Levels
The 840Ci came standard with a generous array of features, reflecting its luxury positioning. Standard equipment included leather upholstery, power-adjustable seats with memory function, automatic climate control, a premium sound system, and a sunroof. Optional extras included upgraded leather, a navigation system (a relatively new technology at the time), and various cosmetic enhancements. The interior design was characterized by its elegant simplicity and high-quality materials. The dashboard layout was driver-focused, with all essential controls within easy reach.
Chassis & Braking
The E31 8 Series featured a robust chassis designed for high-speed stability and handling. The 840Ci utilized a wishbone front suspension and a coil spring rear suspension. The braking system consisted of ventilated discs at the front and solid discs at the rear, equipped with ABS (Anti-lock Braking System) as standard. The steering was a hydraulic power-assisted rack and pinion system, providing precise and responsive steering feel. The suspension was tuned to provide a comfortable ride without sacrificing handling prowess. The car rode on 16-inch alloy wheels with 235/50 R16 tires.
Market Reception & Comparison
The 840Ci was generally well-received by automotive critics. It was praised for its powerful engine, refined handling, and luxurious interior. However, some critics noted that it lacked the ultimate performance of the 850i and that its price was relatively high compared to other grand tourers. Compared to the 830i, the 840Ci offered a significant performance upgrade, justifying its higher price tag. Against competitors like the Mercedes-Benz SL and Porsche 928, the 840Ci offered a unique blend of luxury, performance, and technology. Fuel economy, while not a primary concern for buyers in this segment, was reasonable for a V8-powered coupe.
Legacy
The BMW 840Ci 4.4 has become a sought-after classic among enthusiasts. The M62B44 engine is known for its reliability and durability, provided it is properly maintained. Common issues include cooling system components and occasional oil leaks. The E31 8 Series, in general, is becoming increasingly collectible, with well-maintained examples commanding high prices in the used car market. The 840Ci represents a sweet spot in the lineup, offering a compelling combination of performance, luxury, and relative affordability. Its timeless design and engaging driving experience continue to appeal to enthusiasts today, solidifying its place as a modern classic.
