Powertrain & Engine Architecture
The heart of the 740d xDrive Steptronic is the N57D30B, a 3.0-liter inline-six cylinder diesel engine. This engine is a member of BMW’s highly regarded N57 family, known for its robust construction and sophisticated technology. The N57D30B utilizes a common rail direct injection system, delivering fuel at extremely high pressures for optimized combustion. A variable geometry turbocharger (VGT) with intercooling further enhances performance and efficiency. The engine also features four valves per cylinder and a sophisticated engine management system. The 8-speed Steptronic automatic transmission, a BMW staple, provides smooth and efficient gear changes. This transmission is known for its quick responsiveness and ability to adapt to driving conditions. The ‘xDrive’ designation indicates BMW’s intelligent all-wheel-drive system, providing enhanced traction and stability in various weather conditions.
Driving Characteristics
The 740d xDrive Steptronic delivers a refined and powerful driving experience. The 630 Nm (464.66 lb-ft) of torque available from just 1500 rpm provides effortless acceleration and strong mid-range performance. While not as overtly sporty as the gasoline-powered 750i, the 740d offers a more than adequate 0-60 mph time of around 5.1 seconds. The 8-speed automatic transmission is well-tuned, providing seamless shifts and contributing to the car’s overall smoothness. The xDrive all-wheel-drive system inspires confidence, particularly in inclement weather. Compared to the 730d, the 740d offered a significant performance upgrade, while remaining more fuel-efficient than the 750i. The automatic transmission, while convenient, doesn’t offer the same level of driver engagement as the available manual options in other 7 Series models.
Equipment & Trim Levels
The 740d xDrive Steptronic came standard with a high level of equipment, befitting its flagship status. Standard features typically included leather upholstery, power-adjustable heated front seats, a premium sound system, navigation, and a comprehensive suite of safety features. Optional extras were plentiful, including massaging seats, rear-seat entertainment, a head-up display, and various driver assistance systems like lane departure warning and adaptive cruise control. Interior trim options ranged from wood veneers to aluminum accents, allowing buyers to personalize their vehicle. The 740d generally sat in the mid-range of the 7 Series lineup, offering a compelling balance of luxury, performance, and efficiency.
Chassis & Braking
The F01 LCI 7 Series featured a double-wishbone front suspension and an integral-IV multi-link rear suspension, providing a comfortable and controlled ride. The 740d xDrive Steptronic was equipped with ventilated disc brakes on all four wheels, providing ample stopping power. The ABS (Anti-lock Braking System) and Dynamic Stability Control (DSC) were standard features, enhancing safety and stability. The suspension was tuned to prioritize comfort, but still offered good handling characteristics. The xDrive system actively distributes torque between the front and rear axles, optimizing traction and stability.
Market Reception & Comparison
The 740d xDrive Steptronic was well-received by automotive critics, who praised its blend of performance, efficiency, and luxury. It was often seen as the sweet spot in the 7 Series range, offering a compelling alternative to the more expensive 750i and the less powerful 730d. Fuel economy was a significant selling point, with the 740d achieving around 39.2 US mpg in combined driving. Reliability was generally good, although diesel engines can be more susceptible to issues with the fuel injection system and turbocharger over time. Compared to its rivals, the 740d offered a more engaging driving experience than the Mercedes-Benz S 350 BlueTEC, while providing similar levels of luxury and refinement.
Legacy
The N57D30B engine has proven to be a durable and reliable powerplant, and the 740d xDrive Steptronic remains a desirable used car today. While maintenance costs can be higher than those of comparable gasoline-powered vehicles, the 740d offers a unique combination of luxury, performance, and fuel efficiency. The F01 LCI 7 Series, in general, is considered a well-built and comfortable grand tourer, and the 740d variant continues to appeal to buyers seeking a sophisticated and capable luxury sedan.
