INTRODUCTION
The G12 generation BMW 7 Series, launched in 2015, represented a significant departure in design and technology for the brand’s flagship sedan. The 2019 LCI (Life Cycle Impulse) facelift brought updated styling, enhanced technology, and refined powertrains. The 750Li xDrive Steptronic, introduced within this facelift, occupied the upper echelon of the 7 Series range. It was designed to appeal to buyers seeking a blend of exhilarating performance, luxurious appointments, and advanced driver-assistance systems. The “Li” designation denotes the long-wheelbase variant, offering increased rear legroom and a more spacious interior, catering to the preferences of discerning customers, particularly in markets like China.
Powertrain & Engine Architecture
At the heart of the 750Li xDrive lies the N63B44D engine, a 4.4-liter twin-turbocharged V8. This engine is a cornerstone of BMW’s performance strategy, known for its smooth power delivery and impressive torque output. The N63 engine utilizes direct fuel injection, ensuring precise fuel metering and optimized combustion. The twin-scroll turbochargers, positioned within the V of the engine, minimize turbo lag and provide a broad, flat torque curve. The engine produces 530 horsepower at 5,500-6,000 rpm and a substantial 750 Nm (553 lb-ft) of torque between 1,800 and 4,600 rpm. This power is channeled through an 8-speed Steptronic automatic transmission, renowned for its quick and seamless shifts. The Steptronic transmission features adaptive shift programs that adjust to the driver’s style and road conditions. The xDrive all-wheel-drive system intelligently distributes power between the front and rear axles, enhancing traction and stability in all weather conditions.
Driving Characteristics
The 750Li xDrive delivers a driving experience that is both refined and engaging. The combination of the powerful V8 engine and the responsive Steptronic transmission results in brisk acceleration – 0 to 60 mph in approximately 3.9 seconds. While not as overtly sporty as some of BMW’s smaller models, the 750Li offers ample power for effortless highway cruising and confident overtaking. The xDrive system provides surefooted handling, particularly in inclement weather. Compared to the 740i (with its inline-six engine), the 750Li offers a significant increase in power and torque, resulting in noticeably quicker acceleration and a more authoritative feel. The 750Li also differs from the diesel-powered 730d and 740d models, offering a smoother, more linear power delivery and a more traditional V8 soundtrack.
Equipment & Trim Levels
The 750Li xDrive came standard with a comprehensive array of luxury features. Interior appointments included premium leather upholstery, multi-contour seats with massage function, and a luxurious wood trim. Standard technology included BMW’s iDrive infotainment system with a large touchscreen display, a premium sound system (often Bowers & Wilkins), and a head-up display. Optional extras included rear-seat entertainment systems, a panoramic sunroof, and various driver-assistance features such as adaptive cruise control, lane-keeping assist, and parking assist. The long-wheelbase configuration provided significantly more rear legroom than the standard-wheelbase 7 Series, enhancing comfort for rear passengers.
Chassis & Braking
The 750Li xDrive features a sophisticated chassis designed to balance ride comfort and handling precision. The front suspension utilizes a double-wishbone design, while the rear suspension employs an independent multi-link setup. Adaptive dampers are standard, allowing the driver to adjust the suspension firmness to suit their preferences. The braking system consists of ventilated discs on all four wheels, providing ample stopping power. ABS (Anti-lock Braking System) and electronic stability control are standard safety features. The vehicle’s weight, approximately 2,075 kg (4,575 lbs), is managed effectively by the chassis and braking systems, contributing to a composed and confident driving experience.
Market Reception & Comparison
The 750Li xDrive was generally well-received by automotive critics, who praised its powerful engine, luxurious interior, and advanced technology. However, some reviewers noted that the long-wheelbase configuration could make the car feel large and cumbersome in tight urban environments. Compared to its competitors, such as the Mercedes-Benz S-Class and the Audi A8, the 750Li offered a more driver-focused experience, with sharper handling and a more engaging powertrain. Fuel economy, while respectable for a V8-powered luxury sedan (around 24.8-24.5 mpg combined), was not a primary strength of the 750Li. Reliability reports have been generally positive, although some owners have reported minor issues with the infotainment system and electronic components.
Legacy
The BMW 750Li xDrive (G12 LCI) represents a high point in BMW’s luxury sedan development. The N63 engine, while eventually superseded by newer powertrains, remains a robust and capable unit. On the used car market, these models hold their value relatively well, particularly those with low mileage and a comprehensive service history. The combination of performance, luxury, and technology continues to appeal to buyers seeking a premium driving experience. While newer 7 Series models offer even more advanced features and improved efficiency, the G12 LCI 750Li xDrive remains a desirable and well-regarded luxury sedan.
