The BMW M760Li xDrive, part of the G12 Long wheelbase 7 Series facelift (LCI) produced from 2019 to 2022, represents the pinnacle of performance and luxury within the 7 Series range. Positioned as the flagship model, it offered a significantly more potent alternative to the 740i and 750i variants. This model aimed to compete directly with high-performance luxury sedans like the Mercedes-Benz S65 AMG and the Audi S8, offering a blend of opulent comfort and exhilarating speed. The “Li” designation signifies the long-wheelbase version, prioritizing rear passenger space, a key consideration in markets like China where chauffeur-driven luxury is prevalent.

Powertrain & Engine Architecture
The heart of the M760Li is BMW’s N74B66C 6.6-liter twin-turbocharged V12 engine. This engine, a descendant of BMW’s long-standing V12 tradition, utilizes direct fuel injection and variable valve timing (Double-VANOS) to optimize performance and efficiency. The twin-scroll turbochargers are positioned within the V of the engine, minimizing turbo lag and providing a broad torque curve. The engine produces 585 horsepower at 5250-5750 rpm and a massive 850 Nm (626 lb-ft) of torque between 1600 and 4500 rpm. This power is channeled through an 8-speed Steptronic automatic transmission, which features smooth and rapid gear changes. The xDrive all-wheel-drive system ensures optimal traction in all conditions, distributing power between the front and rear axles as needed.
Driving Characteristics
The M760Li delivers a driving experience that is both incredibly refined and surprisingly athletic for a car of its size and weight. The abundant torque from the V12 engine provides effortless acceleration, with a 0-60 mph time of just 3.6 seconds. The 8-speed automatic transmission is well-tuned, offering seamless shifts and contributing to the car’s overall smoothness. While not as overtly sporty as some of BMW’s smaller models, the M760Li offers a confident and composed ride, with the adaptive suspension effectively absorbing bumps and maintaining stability. Compared to the 750i (with its V8 engine), the M760Li provides a significantly more powerful and luxurious experience, albeit with a noticeable increase in fuel consumption.
Equipment & Trim Levels
The M760Li came standard with a comprehensive array of luxury features, including premium leather upholstery, heated and ventilated front seats with massage function, a panoramic sunroof, and a Bowers & Wilkins Diamond Surround Sound System. Standard driver-assistance systems included adaptive cruise control, lane departure warning, and automatic emergency braking. Optional extras included rear-seat entertainment systems, individual rear seats with a center console, and a variety of interior trim options. The long wheelbase provided generous rear legroom, making it a particularly appealing choice for passengers.
Chassis & Braking
The M760Li features a double-wishbone front suspension and an independent multi-link rear suspension, optimized for both comfort and handling. Adaptive dampers are standard, allowing the driver to adjust the suspension settings to suit their preferences. The braking system consists of ventilated discs on all four wheels, providing ample stopping power. The car also incorporates BMW’s Dynamic Stability Control (DSC) system, which helps to maintain stability during cornering and emergency maneuvers.
Market Reception & Comparison
The M760Li was generally well-received by automotive critics, who praised its powerful engine, luxurious interior, and refined driving experience. However, its high price tag and relatively poor fuel economy were often cited as drawbacks. Compared to its rivals, the M760Li offered a unique combination of performance and luxury, with a focus on providing a comfortable and engaging driving experience. While the Mercedes-Benz S65 AMG offered even more raw power, the M760Li was often considered to be more balanced and refined.
Legacy
The N74B66C V12 engine, while complex, has proven to be relatively reliable when properly maintained. Common issues include oil leaks and occasional problems with the cooling system. However, with regular servicing and preventative maintenance, these engines can provide many years of trouble-free operation. On the used car market, the M760Li remains a desirable option for those seeking a high-performance luxury sedan. Its combination of power, luxury, and exclusivity ensures that it will continue to be appreciated by enthusiasts for years to come.
