2016-2019 BMW 7 Series (G11) 750d (400 Hp) xDrive Steptronic

The BMW 750d xDrive, produced between 2016 and 2019 as part of the G11 generation of the 7 Series, represented a compelling blend of performance and efficiency within BMW’s flagship sedan lineup. Positioned as a mid-to-high range offering, it slotted between the 730d and the range-topping 760i, appealing to buyers seeking substantial power and torque from a diesel engine coupled with the convenience of all-wheel drive and an automatic transmission. This variant was primarily aimed at the European and Asian markets, where diesel engines held greater popularity due to fuel economy and tax incentives, though it was also available in limited numbers in North America.

Technical Specifications

Powertrain & Engine Architecture

The heart of the 750d xDrive is BMW’s B57D30C 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 operating at extremely high pressures (2,200 bar) for optimized combustion and reduced emissions. It employs a variable geometry turbocharger (VGT) and an additional turbocharger, creating a twin-turbo setup, to deliver both strong low-end torque and high-end power. The engine also incorporates BMW’s BluePower technology, including a diesel particulate filter and NOx catalyst to meet stringent Euro 6c emission standards. The engine is longitudinally mounted at the front of the vehicle. Paired with the engine is BMW’s 8-speed Steptronic automatic transmission, known for its smooth shifts and efficiency. This transmission features a torque converter and allows for both fully automatic operation and manual gear selection via steering wheel-mounted paddles.

Driving Characteristics

The 750d xDrive delivers a remarkably refined driving experience. The high torque output of 760 Nm (560 lb-ft) available from just 2000 rpm provides effortless acceleration in virtually any situation. The 0-60 mph sprint takes approximately 4.4 seconds, making it a genuinely quick sedan. The eight-speed automatic transmission is well-tuned to the engine’s characteristics, providing seamless gear changes and contributing to the car’s overall smoothness. Compared to the 730d, the 750d offers a significant performance boost, while remaining more fuel-efficient and offering a more relaxed driving experience than the petrol-powered 750i. The xDrive all-wheel-drive system provides excellent traction and stability, particularly in adverse weather conditions. The gear ratios are optimized for both acceleration and highway cruising, with a relatively tall final drive to enhance fuel economy.

Equipment & Trim Levels

The 750d xDrive typically came well-equipped as standard. Interior features included leather upholstery, power-adjustable front seats with memory function, a premium sound system, and a large infotainment screen with BMW’s iDrive system. Standard safety features included a comprehensive suite of airbags, ABS, stability control, and various driver-assistance systems. Optional extras included features like massaging seats, a rear-seat entertainment system, a panoramic sunroof, and advanced parking assistance features. Trim levels varied slightly by market, but generally offered options for different interior color schemes, wood or aluminum trim, and exterior styling packages.

Chassis & Braking

The G11 7 Series utilizes a sophisticated chassis design. The front suspension features a double-wishbone setup, while the rear employs an independent multi-link suspension. This configuration provides a comfortable ride and precise handling. The 750d xDrive typically came equipped with ventilated disc brakes on all four wheels, providing ample stopping power. The braking system is augmented by ABS, electronic brakeforce distribution, and brake assist. The suspension is electronically controlled, allowing for adjustable damping settings to tailor the ride to the driver’s preferences. Stabilizer bars are fitted front and rear to reduce body roll during cornering.

Market Reception & Comparison

The 750d xDrive was generally well-received by automotive critics. It was praised for its powerful engine, smooth transmission, comfortable ride, and luxurious interior. Critics noted that the diesel engine provided a compelling alternative to the petrol engines, offering similar performance with improved fuel economy. Compared to the 730d, the 750d offered a noticeable performance upgrade, justifying the higher price tag for buyers prioritizing power. Fuel economy figures were competitive for a vehicle of its size and performance, typically achieving around 38-40 mpg on the combined cycle. Reliability reports have been generally positive, with the B57 engine proving to be a durable and dependable unit.

Legacy

The BMW 750d xDrive (G11) has established itself as a desirable used car, particularly for those seeking a blend of luxury, performance, and efficiency. The B57 engine is known for its longevity and relatively low maintenance costs, making it a practical choice for long-term ownership. While diesel vehicles have faced increased scrutiny in recent years, the 750d remains a popular option for buyers who appreciate its unique combination of attributes. The G11 generation 7 Series, and the 750d variant specifically, represents a high point in BMW’s engineering and design, offering a refined and capable luxury sedan experience.
