Powertrain & Engine Architecture
The heart of the 740Ld xDrive is BMW’s B57D30B inline-six diesel engine. This engine is a member of the modular B-series engine family, known for its efficiency and refinement. The B57 features a common-rail direct injection system operating at extremely high pressures (2,500 bar) for optimized combustion. A twin-scroll turbocharger with variable geometry turbine (VGT) technology, along with intercooling, delivers strong torque across a broad rev range. The engine also incorporates BMW’s BluePower diesel technology, including a diesel particulate filter (DPF) and NOx catalyst to meet stringent Euro 6d-TEMP emission standards. The 8-speed Steptronic automatic transmission is a cornerstone of BMW’s drivetrain strategy, offering smooth and quick shifts. It features a torque converter lockup clutch for improved efficiency and a wide gear ratio spread to optimize both acceleration and fuel economy.
Driving Characteristics
The 740Ld xDrive delivers a distinctly different driving experience compared to its gasoline-powered siblings, such as the 740i or 750i. While lacking the outright acceleration of the higher-horsepower models, the 740Ld compensates with a substantial 680 Nm (501.54 lb-ft) of torque available from just 1750 rpm. This provides effortless acceleration in everyday driving situations and strong passing power. The Steptronic transmission is well-tuned to the engine’s characteristics, providing seamless gear changes. The xDrive all-wheel-drive system enhances traction and stability, particularly in adverse weather conditions. Compared to a manual transmission, the automatic prioritizes comfort and ease of use, but sacrifices some driver engagement. The long wheelbase contributes to a smooth and comfortable ride, absorbing road imperfections effectively.
Equipment & Trim Levels
The 740Ld xDrive typically came well-equipped as standard, reflecting its position as a luxury vehicle. Standard features included leather upholstery, power-adjustable front seats with memory function, a premium sound system, a large infotainment screen with iDrive controller, navigation, and a comprehensive suite of safety features like automatic emergency braking, lane departure warning, and adaptive cruise control. Optional extras included features like massaging seats, a rear-seat entertainment system, upgraded leather options, and various driver-assistance packages. The interior design was characterized by high-quality materials and a focus on creating a refined and comfortable cabin environment.
Chassis & Braking
The G12 7 Series utilizes a sophisticated chassis design. The front suspension employs a double-wishbone setup, while the rear features an independent multi-link suspension. This configuration provides a good balance of ride comfort and handling precision. The 740Ld xDrive typically came equipped with ventilated disc brakes on all four wheels, providing ample stopping power. The electronic stability control (ESC) system works in conjunction with the xDrive all-wheel-drive system to maintain stability and control in challenging driving conditions. The steering system is an electric power steering (EPS) system, offering precise and responsive steering feel.
Market Reception & Comparison
The 740Ld xDrive was generally well-received by automotive critics, who praised its blend of performance, efficiency, and luxury. The diesel engine was noted for its refinement and strong torque output. Fuel economy was a significant advantage, particularly compared to the gasoline-powered models. However, some critics noted that the diesel engine lacked the responsiveness and sound of the gasoline engines. Compared to the 730d, the 740Ld offered a noticeable power upgrade. Against the 740i, the 740Ld traded some outright performance for improved fuel economy and lower running costs.
Legacy
The B57 engine family, including the B57D30B found in the 740Ld, has proven to be remarkably reliable. While diesel engines generally require more diligent maintenance (particularly regarding the DPF system), these engines are known for their longevity. On the used car market, the 740Ld xDrive represents a compelling value proposition for buyers seeking a luxurious and efficient long-distance cruiser. The combination of a powerful diesel engine, all-wheel drive, and a comfortable interior makes it a desirable option, especially for those who prioritize fuel economy and low-speed torque over outright performance.
