The BMW 740Li xDrive, produced between 2016 and 2019 as part of the G12 Long wheelbase 7 Series generation, represented a significant offering in the luxury sedan segment. Positioned as a mid-range variant within the 7 Series lineup, it bridged the gap between the entry-level 730d and the high-performance 750i models. The “Li” designation signifies an extended wheelbase, primarily aimed at providing increased rear passenger legroom – a feature particularly valued in markets like China, where the car saw substantial sales. This variant combined a potent inline-six engine with BMW’s xDrive all-wheel-drive system and the Steptronic eight-speed automatic transmission, offering a blend of performance, comfort, and technology.

Powertrain & Engine Architecture
The heart of the 740Li is BMW’s B58B30 3.0-liter inline-six engine. This engine is a member of BMW’s modular engine family, known for its smooth power delivery and efficiency. It utilizes direct fuel injection, a twin-scroll turbocharger, and variable valve timing (VANOS) and valve lift (Valvetronic) technologies to optimize performance and fuel economy. The B58 engine is renowned for its robust construction and relatively simple design compared to some of its competitors. The engine’s output of 326 horsepower and 450 Nm (331.9 lb-ft) of torque is delivered across a broad rev range, contributing to effortless acceleration. Paired with the engine is the ZF 8HP80 eight-speed automatic transmission, marketed by BMW as “Steptronic.” This transmission is known for its smooth and quick shifts, and its ability to adapt to driving conditions. The xDrive all-wheel-drive system distributes power between the front and rear axles as needed, enhancing traction and stability, particularly in adverse weather conditions.
Driving Characteristics
The 740Li xDrive offers a refined and comfortable driving experience. The combination of the smooth inline-six engine and the eight-speed automatic transmission results in effortless acceleration and relaxed cruising. While not as overtly sporty as the 750i, the 740Li provides ample power for overtaking and merging onto highways. The xDrive system provides confident handling in all conditions. The Steptronic transmission’s gear ratios are tuned for both fuel efficiency and responsive acceleration. Compared to the 730d, the 740Li offers significantly more power and a more engaging driving experience. Compared to the 750i with its V8 engine, the 740Li provides a good balance of performance and efficiency, making it a more practical choice for everyday driving.
Equipment & Trim Levels
The 740Li xDrive came standard with a comprehensive list of features, befitting its luxury status. These included leather upholstery, power-adjustable front seats with memory function, a panoramic sunroof, a premium sound system, and a comprehensive suite of driver-assistance systems, such as lane departure warning, forward collision warning, and automatic emergency braking. Optional extras included rear-seat entertainment systems, massaging seats, a head-up display, and various interior trim options. The extended wheelbase (“Li”) version specifically focused on rear passenger comfort, often equipped with individual rear seats and a rear-seat control panel for climate and entertainment functions.
Chassis & Braking
The G12 7 Series utilizes a sophisticated chassis design featuring a double-wishbone front suspension and an independent multi-link rear suspension. This setup provides a comfortable ride while maintaining good handling characteristics. Air suspension was standard, further enhancing ride quality and allowing for adjustable ride height. The 740Li xDrive came equipped with ventilated disc brakes on all four wheels, providing ample stopping power. ABS, dynamic stability control, and traction control were standard safety features.
Market Reception & Comparison
The 740Li xDrive was generally well-received by automotive critics. It was praised for its comfortable ride, refined interior, and potent engine. Critics noted that the 740Li offered a compelling alternative to its competitors, such as the Mercedes-Benz S-Class and the Audi A8. Fuel economy was considered respectable for a vehicle of its size and performance. Reliability reports have generally been positive, with the B58 engine proving to be a durable and dependable unit. However, some owners have reported issues with the electronic systems, which are common in modern luxury vehicles.
Legacy
The BMW 740Li xDrive (G12) remains a desirable used luxury sedan. The B58 engine’s reputation for reliability and performance has helped maintain its value. While newer generations of the 7 Series offer even more advanced technology and features, the G12 740Li continues to provide a comfortable, refined, and enjoyable driving experience. Its blend of performance, luxury, and technology makes it a compelling choice for buyers seeking a high-end sedan at a more accessible price point.
