INTRODUCTION
The G11 7 Series, launched in 2015, represented a significant departure for BMW’s flagship sedan, embracing lightweight construction with carbon fiber reinforced plastic (CFRP) in the passenger cell. The 2019 LCI brought a refreshed exterior design, updated interior technology, and powertrain enhancements. The 740d xDrive, introduced with the LCI, combined a potent diesel engine with mild hybrid assistance, aiming to deliver both strong performance and improved fuel economy. This model was primarily marketed towards discerning buyers in Europe and Asia, where diesel engines remained popular due to their efficiency and torque characteristics. While diesel options were less common in the US market, the 740d xDrive showcased BMW’s commitment to offering a diverse range of powertrain choices globally.
Powertrain & Engine Architecture
At the heart of the 740d xDrive lies the B57D30B, a 3.0-liter inline-six diesel engine. This engine is a member of BMW’s modular engine family and features a sophisticated common-rail direct injection system operating at pressures up to 2,500 bar. The B57 utilizes a variable geometry turbocharger and an intercooler to optimize performance and efficiency. The mild hybrid system, a 48V setup, incorporates a 11 hp electric motor integrated into the drivetrain. This system provides a power boost during acceleration, enables smoother start-stop operation, and allows for coasting with the engine switched off, further enhancing fuel economy. The engine produces 700 Nm (516 lb-ft) of torque between 1750 and 2250 rpm. The eight-speed Steptronic automatic transmission is a crucial component, offering smooth and rapid gear changes. It’s programmed for both comfort and performance, adapting to the driver’s style and road conditions.
Driving Characteristics
The 740d xDrive delivers a refined and effortless driving experience. The combination of the potent diesel engine and the eight-speed automatic transmission results in strong acceleration, with a 0-60 mph time of around 4.8 seconds. The mild hybrid system contributes to a seamless power delivery, masking any potential turbo lag. While not as overtly sporty as the gasoline-powered 750i, the 740d offers ample power for confident overtaking and highway cruising. The xDrive all-wheel-drive system provides excellent traction in all weather conditions, enhancing stability and control. The air suspension contributes to a comfortable ride, absorbing bumps and imperfections in the road surface effectively. Compared to the 730d, the 740d offers a noticeable performance upgrade, while the 750i provides a more exhilarating, but less efficient, driving experience.
Equipment & Trim Levels
The 740d xDrive came standard with a comprehensive array of luxury features. These included leather upholstery, power-adjustable heated front seats, a panoramic sunroof, and a premium sound system. BMW’s iDrive infotainment system, with its touchscreen display and gesture control, was also standard. Optional extras included upgraded leather options, rear-seat entertainment systems, massaging seats, and advanced driver-assistance features such as adaptive cruise control and lane-keeping assist. The interior design emphasized luxury and sophistication, with high-quality materials and meticulous attention to detail. The dashboard layout was clean and modern, with a focus on intuitive controls.
Chassis & Braking
The 7 Series G11 utilizes a sophisticated chassis design featuring a double-wishbone front suspension and an independent multi-link rear suspension, both incorporating air suspension as standard. This system allows for adjustable ride height and damping characteristics, optimizing comfort and handling. The 740d xDrive is equipped with ventilated disc brakes on all four wheels, providing ample stopping power. Anti-lock braking system (ABS), electronic stability control (ESC), and traction control are standard safety features. The steering system is an electric power-assisted rack-and-pinion setup, offering precise and responsive steering feel.
Market Reception & Comparison
The 740d xDrive was generally well-received by automotive critics. It was praised for its blend of performance, efficiency, and luxury. Reviewers noted the smooth and refined driving experience, the comfortable ride, and the spacious and well-appointed interior. Fuel economy was also a strong point, with the 740d achieving impressive figures for a vehicle of its size and weight. Compared to the 730d, the 740d offered a significant performance advantage, making it a more appealing option for drivers who prioritize power and responsiveness. However, some critics noted that the diesel engine lacked the refinement and sound of the gasoline-powered alternatives.
Legacy
The B57 engine family, including the B57D30B found in the 740d, has proven to be remarkably reliable. These engines are known for their durability and longevity, provided they are properly maintained. The mild hybrid system has also demonstrated good reliability. On the used car market, the G11 740d xDrive represents a compelling value proposition, offering a luxurious and well-equipped grand tourer at a more accessible price point than newer models. However, potential buyers should be aware of the higher maintenance costs associated with a complex vehicle like the 7 Series, and ensure that the car has been regularly serviced according to BMW’s recommendations.
