INTRODUCTION
The 740Li, introduced as part of the G12 7 Series’ LCI (Life Cycle Impulse) facelift in 2019, builds upon the already luxurious foundation of the sixth-generation 7 Series. The LCI brought revised styling, updated technology, and refined powertrain options. The “Li” designation denotes the long-wheelbase version, specifically designed for markets prioritizing rear passenger comfort. This variant occupied a sweet spot in the 7 Series range, offering a substantial power upgrade over the base 730i while remaining more accessible than the flagship M760i. It was aimed at buyers who desired a luxurious and technologically advanced sedan with a capable engine, but didn’t necessarily require the ultimate performance.
Powertrain & Engine Architecture
At the heart of the 740Li lies BMW’s B58B30M1 3.0-liter inline-six engine. This engine is a cornerstone of BMW’s modern powertrain strategy, known for its smooth power delivery and efficiency. The B58 utilizes a single twin-scroll turbocharger, direct fuel injection, and BMW’s VALVETRONIC variable valve timing and Double-VANOS variable camshaft timing systems. These technologies work in concert to optimize combustion, improve throttle response, and enhance fuel economy. The engine produces 335 horsepower at 5500-6500 rpm and 447 Nm (329.69 lb-ft) of torque between 1500-5200 rpm. Paired with the engine is BMW’s 8-speed Steptronic automatic transmission, renowned for its quick and seamless shifts. This transmission features a torque converter and allows for both automatic and manual gear selection via steering wheel-mounted paddles. The transmission is tuned for both comfort and responsiveness, providing smooth upshifts during normal driving and quick downshifts when needed for acceleration.
Driving Characteristics
The 740Li delivers a refined and composed driving experience. While not as overtly sporty as some of BMW’s other models, the 335 hp engine provides ample power for effortless cruising and confident overtaking. The 8-speed Steptronic transmission contributes to this smoothness, offering seamless gear changes that are virtually imperceptible. Compared to the 730i, the 740Li offers a noticeable performance boost, with a 0-60 mph time of 5.3 seconds. However, it doesn’t quite match the outright acceleration of the M760i. The long wheelbase and air suspension contribute to a comfortable ride, effectively absorbing bumps and imperfections in the road. The steering is precise and well-weighted, providing a connected feel to the driver. The rear-wheel drive configuration contributes to a balanced chassis, although xDrive all-wheel drive was also available as an option.
Equipment & Trim Levels
The 740Li came standard with a comprehensive array of luxury features. Interior appointments typically included premium leather upholstery, power-adjustable front and rear seats with heating and ventilation, and a panoramic sunroof. The infotainment system featured a large touchscreen display, iDrive controller, and a premium sound system. Standard safety features included automatic emergency braking, lane departure warning, and adaptive cruise control. Optional extras included a rear-seat entertainment system, massaging seats, a Bowers & Wilkins Diamond surround sound system, and various interior trim options. The long wheelbase provided generous rear legroom, making it particularly well-suited for chauffeured transport.
Chassis & Braking
The 740Li utilizes a double-wishbone front suspension and an independent multi-link rear suspension, both incorporating air suspension with electronic damping control. This system allows the ride height to be adjusted automatically, optimizing comfort and handling. The braking system consists of ventilated discs on all four wheels, providing ample stopping power. Anti-lock braking system (ABS), electronic stability control (ESC), and traction control are standard features. The suspension is tuned to prioritize comfort, but still offers a reasonable level of handling competence. The air suspension helps to minimize body roll during cornering and provides a smooth ride over uneven surfaces.
Market Reception & Comparison
The 740Li was generally well-received by automotive critics. It was praised for its refined driving experience, luxurious interior, and advanced technology. Critics noted that the B58 engine provided a good balance of power and efficiency. Compared to the 730i, the 740Li offered a significant performance upgrade, while remaining more affordable than the M760i. Fuel economy was respectable for a large luxury sedan, with combined figures around 25 US mpg. Reliability has been generally good, although some owners have reported minor issues with the infotainment system. The 740Li positioned itself as a strong competitor to the Mercedes-Benz S450 and Audi A8 55 TFSI, offering a compelling alternative in the luxury sedan segment.
Legacy
The B58 engine has proven to be a robust and reliable powerplant, and the 740Li’s powertrain combination has maintained a good reputation in the used car market. The G12 7 Series, including the 740Li, represents a high point in BMW’s luxury sedan offerings, combining advanced technology, refined driving dynamics, and a luxurious interior. As these vehicles age, maintenance costs may increase, but the B58 engine’s inherent reliability and the availability of parts suggest that well-maintained examples will continue to provide years of comfortable and reliable service. The 740Li remains a desirable option for buyers seeking a luxurious and capable sedan with a proven track record.
