The BMW M760Li xDrive, part of the G12 generation of the 7 Series long-wheelbase sedan, represented the pinnacle of performance for the model line between its introduction in 2017 and discontinuation in 2019. Positioned as the flagship variant, it offered a substantial upgrade over the 750i and 740i models, targeting buyers seeking uncompromising power and luxury. The “Li” designation signifies the extended wheelbase, providing increased rear passenger space, a key feature for markets like China where chauffeur-driven luxury sedans are highly sought after. This model aimed to compete directly with high-performance luxury vehicles from Mercedes-Benz and Audi.

Powertrain & Engine Architecture
The heart of the M760Li is BMW’s N74B66B 6.6-liter twin-turbocharged V12 engine. This engine, a descendant of BMW’s long-standing V12 tradition, utilizes direct fuel injection and a sophisticated double-VANOS variable valve timing system. The twin-turbochargers, positioned within the V of the engine, provide significant boost, contributing to the engine’s impressive 800 Nm (590 lb-ft) of torque available from just 1550 rpm. The engine is paired with BMW’s 8-speed Steptronic automatic transmission, featuring smooth and rapid gear changes. This transmission is specifically tuned to handle the immense power output of the V12, offering both automatic and manual shift modes. The xDrive all-wheel-drive system distributes power between the front and rear axles, enhancing traction and stability, particularly in adverse weather conditions.
Driving Characteristics
The M760Li delivers a driving experience that blends effortless power with remarkable refinement. The combination of the V12 engine and the 8-speed automatic transmission results in incredibly swift acceleration – 0 to 60 mph in approximately 3.5 seconds. The xDrive system ensures optimal grip, allowing the car to put its power down effectively. While not as overtly sporty as some of BMW’s smaller models, the M760Li offers a commanding presence and a sense of effortless speed. The steering is precise and well-weighted, and the suspension, utilizing BMW’s adaptive damping system, provides a comfortable ride without sacrificing handling composure. The gear ratios are optimized for both acceleration and high-speed cruising, making it an excellent grand tourer.
Equipment & Trim Levels
As the range-topping model, the M760Li came standard with a comprehensive array of luxury features. These included premium Nappa leather upholstery, multi-contour seats with massage function, a Bowers & Wilkins Diamond Surround Sound System, a rear-seat entertainment system with dual 10.2-inch screens, and a panoramic sunroof. Standard driver-assistance systems included adaptive cruise control, lane departure warning, and automatic emergency braking. Optional extras included individual leather trim options, rear executive lounge seating with a reclining function, and various cosmetic enhancements. The interior design emphasized luxury and sophistication, with high-quality materials and meticulous attention to detail.
Chassis & Braking
The M760Li’s chassis is engineered to handle the engine’s substantial power and provide a comfortable ride. It features a double-wishbone front suspension and an independent multi-link rear suspension, both with adaptive dampers. The suspension is tuned to provide a balance between comfort and handling, minimizing body roll and maximizing stability. 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 control in challenging driving situations.
Market Reception & Comparison
The M760Li was generally well-received by automotive critics, who praised its powerful engine, luxurious interior, and refined driving experience. However, some reviewers noted its high price tag and relatively high fuel consumption. Compared to the 750i, the M760Li offered a significant performance upgrade, but at a considerable cost. Against competitors like the Mercedes-Benz S65 AMG and the Audi A8 L 6.3, the M760Li held its own in terms of performance and luxury, offering a unique blend of German engineering and opulent comfort. Fuel economy, as expected for a V12 engine, was not a strong point, averaging around 18.4 US mpg combined.
Legacy
The G12 M760Li, while a relatively short-lived model, represents a high point in BMW’s V12 engine development. The N74B66B engine, despite its complexity, proved to be a reliable powerplant when properly maintained. On the used car market, the M760Li commands a premium price due to its exclusivity and performance. Maintenance costs are higher than those of the 740i or 750i models, reflecting the complexity of the V12 engine and its associated systems. However, for buyers seeking a truly luxurious and powerful sedan, the M760Li remains a compelling option.
