Powertrain & Engine Architecture
At the heart of the 440i xDrive lies BMW’s B58B30A 3.0-liter inline-six engine. This engine is a significant evolution of the N55, featuring a single twin-scroll turbocharger, direct fuel injection, and Double-VANOS variable valve timing. The B58 is known for its smooth power delivery and robust construction. The engine produces 326 horsepower at 5,500 rpm and 450 Nm (331.9 lb-ft) of torque between 1,380 and 5,000 rpm. This broad torque curve contributes to strong acceleration in real-world driving conditions. The engine is paired with BMW’s ZF 8HP eight-speed automatic transmission, known for its quick and smooth shifts. The ‘Steptronic’ designation indicates the inclusion of paddle shifters for manual gear selection. The xDrive all-wheel-drive system utilizes a multi-plate clutch to distribute torque between the front and rear axles, enhancing traction and stability, particularly in adverse weather conditions.
Driving Characteristics
The 440i xDrive Steptronic delivers a refined and engaging driving experience. The combination of the potent inline-six and the eight-speed automatic results in brisk acceleration – 0 to 60 mph in approximately 4.7 seconds. While not as raw or focused as the M4, the 440i offers ample power for both highway cruising and spirited driving on winding roads. The automatic transmission is well-programmed, providing seamless shifts in automatic mode and responsive control when using the paddle shifters. The xDrive system provides excellent grip, inspiring confidence in various conditions. Compared to the 428i, the 440i offers a noticeable increase in power and torque, resulting in a more effortless driving experience. The 440i also feels more planted and stable than rear-wheel-drive variants, thanks to the xDrive system.
Equipment & Trim Levels
The 440i xDrive 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 were plentiful, including a head-up display, navigation system, adaptive cruise control, a sunroof, and various interior trim options. The 440i could also be equipped with the M Sport package, which added more aggressive styling cues, sport seats, and a sport-tuned suspension.
Chassis & Braking
The F32 4 Series features a sophisticated chassis design with a multi-link rear suspension. The 440i xDrive utilizes a slightly stiffer suspension setup compared to lower-powered variants to handle the increased power and torque. The braking system consists of ventilated discs on all four wheels, providing ample stopping power. ABS, dynamic stability control (DSC), and traction control are standard safety features. The xDrive system also incorporates torque vectoring, which can selectively apply braking force to individual wheels to improve cornering agility.
Market Reception & Comparison
The 440i xDrive was generally well-received by automotive critics. It was praised for its powerful engine, refined driving dynamics, and comfortable interior. Reviewers noted that the xDrive system added a layer of security and confidence, making it a practical choice for drivers in regions with inclement weather. Compared to the 428i, the 440i offered a significant performance upgrade, while remaining relatively fuel-efficient. Fuel economy figures averaged around 33.6 mpg combined. Compared to the M4, the 440i offered a more comfortable and refined driving experience, albeit with slightly less outright performance.
Legacy
The B58 engine has proven to be remarkably reliable, and the 440i xDrive continues to be a sought-after model in the used car market. The combination of performance, luxury, and all-weather capability makes it a compelling option for buyers seeking a sporty and practical coupe. Regular maintenance, including oil changes and timely servicing of the cooling system, is crucial for ensuring the long-term reliability of the B58 engine. The ZF 8HP transmission is also known for its durability, but fluid changes should be performed according to BMW’s recommended service intervals. Overall, the F32 440i xDrive represents a well-engineered and enjoyable driving machine that has aged gracefully.
