The BMW 740d xDrive, part of the G11 LCI (Life Cycle Impulse) facelift of the 7 Series, represents a significant offering in the large luxury sedan segment. Produced from 2019 through July 2020, this variant combined a potent diesel engine with BMW’s xDrive all-wheel-drive system and the Steptronic automatic transmission. Positioned as a mid-range option within the 7 Series lineup, it aimed to deliver a balance of performance, efficiency, and luxury features, appealing to buyers seeking a refined driving experience without the outright performance focus of the M760i or the higher cost of the 750i. The G11 generation, launched in 2015, aimed to recapture BMW’s dominance in the luxury sedan market, and the LCI update brought styling revisions and updated technology.

Powertrain & Engine Architecture
The heart of the 740d xDrive is BMW’s B57D30B inline-six diesel engine. This engine is a member of the modular BMW engine family, known for its robust construction and advanced technology. The B57 features a common-rail direct injection system, delivering fuel at extremely high pressures for optimized combustion. A sophisticated twin-turbocharger setup – one low-pressure and one high-pressure turbo – provides both strong low-end torque and high-end power. The engine also incorporates variable valve timing (VANOS) and Double-VANOS technology for improved efficiency and responsiveness. The 8-speed Steptronic automatic transmission is a crucial component, offering smooth and quick shifts. It’s programmed to adapt to driving style and conditions, and includes features like launch control and coasting mode for enhanced efficiency. The transmission is paired with BMW’s xDrive all-wheel-drive system, which intelligently distributes power between the front and rear axles for optimal traction and stability.
Driving Characteristics
The 740d xDrive delivers a distinctly different driving experience compared to its gasoline-powered siblings or even higher-output diesel variants. While it doesn’t possess the outright acceleration of the 750i, the substantial 680 Nm (501.54 lb-ft) of torque available from just 1750 rpm provides effortless and responsive acceleration in everyday driving situations. The 8-speed automatic transmission is well-matched to the engine’s characteristics, providing smooth gear changes and contributing to a relaxed cruising experience. The xDrive system enhances stability, particularly in adverse weather conditions. Compared to a manual transmission 740d (not commonly offered in the US market), the automatic prioritizes comfort and ease of use over driver engagement. The gear ratios are tuned for efficiency and smooth power delivery, rather than aggressive acceleration.
Equipment & Trim Levels
The 740d xDrive typically came well-equipped, reflecting its position in the luxury segment. Standard features included leather upholstery, power-adjustable front seats with memory function, a premium sound system, a large infotainment screen with iDrive controller, 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 emphasized luxury and sophistication, with high-quality materials and meticulous attention to detail. Dashboard configuration was generally consistent across the 7 Series range, with subtle trim differences based on selected options.
Chassis & Braking
The 7 Series G11 LCI utilized a sophisticated chassis design focused on ride comfort and handling balance. The front suspension employed a double-wishbone setup, while the rear featured an independent multi-link suspension. Air suspension was standard on the 740d xDrive, providing adjustable ride height and damping for a supremely comfortable ride. Braking duties were handled by ventilated discs on all four wheels, providing ample stopping power. The electronic stability control (DSC) system worked in conjunction with the xDrive system to maintain stability and control in various driving conditions. The 740d, due to its weight, generally featured slightly thicker stabilizer bars compared to the lighter 730d models to mitigate body roll.
Market Reception & Comparison
The 740d xDrive was generally well-received by automotive critics. It was praised for its refined driving experience, comfortable ride, and impressive fuel economy for a vehicle of its size and weight. Critics noted that while it didn’t offer the same level of performance as the 750i, it provided a compelling alternative for buyers prioritizing efficiency and a relaxed driving experience. Compared to the 730d, the 740d offered a significant performance upgrade, justifying the higher price tag for those seeking more power. The 740d also offered a more economical alternative to the gasoline-powered 750i, without sacrificing too much in terms of luxury or refinement.
Legacy
The B57 engine family, including the B57D30B found in the 740d, has proven to be remarkably reliable. While diesel engines can be susceptible to issues with the emissions control systems (particularly the diesel particulate filter), the B57 has generally demonstrated good long-term durability. On the used car market, the 740d xDrive represents a good value proposition, offering a luxurious and well-equipped sedan at a more affordable price point than newer models. Maintenance costs are generally reasonable, although preventative maintenance of the emissions system is crucial. The combination of performance, efficiency, and luxury continues to make the G11 740d xDrive a desirable option for buyers seeking a high-end luxury sedan.
