Powertrain & Engine Architecture
The heart of the 440i is BMW’s B58B30A 3.0-liter inline-six engine. This engine is a member of BMW’s modular engine family, known for its smooth power delivery and efficiency. The B58 utilizes a single twin-scroll turbocharger, direct fuel injection, and Double-VANOS variable valve timing for both intake and exhaust camshafts. This combination results in a peak output of 326 horsepower at 5,500 rpm and 450 Nm (331.9 lb-ft) of torque available from a low 1,380 rpm all the way to 5,000 rpm. The engine’s longitudinal mounting and rear-wheel-drive configuration contribute to the car’s balanced handling characteristics. The Steptronic 8-speed automatic transmission is a crucial component, offering smooth and quick shifts. It features adaptive shift programs that adjust to the driver’s style and driving conditions. The transmission’s gear ratios are tuned to maximize both acceleration and fuel efficiency.
Driving Characteristics
The 440i Steptronic delivers a refined yet engaging driving experience. The readily available torque from the B58 engine provides strong acceleration in everyday driving situations. While the automatic transmission doesn’t offer the same level of driver involvement as a manual gearbox, it provides seamless gear changes and contributes to a more relaxed driving experience. Compared to the 428i/430i models, the 440i offers a noticeable performance upgrade, with a 0-60 mph time of around 4.8 seconds. Compared to the M4, the 440i provides a more comfortable ride and is less focused on outright track performance. The Steptronic transmission’s programming prioritizes smooth transitions, which can sometimes feel slightly less responsive than the more aggressive shift points in the M4’s dual-clutch transmission.
Equipment & Trim Levels
The 440i typically came well-equipped as standard. Common features included leather upholstery, power-adjustable front seats with memory function, a premium sound system, automatic climate control, and BMW’s iDrive infotainment system with a central display screen. Optional extras included features like a head-up display, navigation system, adaptive cruise control, and various interior trim options. The Luxury Line and M Sport packages were popular choices, offering distinct styling cues and additional features. The Luxury Line focused on comfort and elegance, while the M Sport package added more aggressive styling elements and a sport-tuned suspension.
Chassis & Braking
The 440i utilizes a sophisticated chassis design featuring an independent coil spring front suspension and an independent multi-link rear suspension. This setup provides a good balance between ride comfort and handling precision. The car is equipped with ventilated disc brakes on all four wheels, providing ample stopping power. ABS (Anti-lock Braking System) is standard, along with electronic stability control and traction control systems. The steering is a rack-and-pinion system with electric power assistance, offering precise and responsive steering feel.
Market Reception & Comparison
The 440i was generally well-received by automotive critics. It was praised for its powerful engine, refined driving experience, and luxurious interior. Compared to the 428i/430i, the 440i offered a significant performance boost without sacrificing comfort. Fuel economy was respectable for a performance coupe, with combined figures ranging from 34.6 to 35.6 US mpg. Reliability has been generally good, although some owners have reported minor issues with the cooling system and electronic components.
Legacy
The BMW 440i (F32) has established itself as a desirable used car option. The B58 engine is known for its durability and tunability, making it a popular choice among enthusiasts. The combination of performance, luxury, and technology continues to appeal to buyers seeking a well-rounded grand tourer. While newer 4 Series models have introduced more advanced features and technologies, the F32 440i remains a compelling option for those who appreciate a classic BMW driving experience.
