Powertrain & Engine Architecture
The heart of the 750i xDrive was the N63B44A 4.4-liter twin-turbocharged V8 engine. This engine represented a significant advancement in BMW’s powertrain technology. It featured direct fuel injection, ensuring precise fuel delivery and improved combustion efficiency. The twin-turbocharger setup, utilizing two small turbochargers, minimized turbo lag and provided a broad, flat torque curve. The engine produced 408 horsepower at 5,500-6,400 rpm and a substantial 600 Nm (442 lb-ft) of torque between 1,750 and 4,500 rpm. This power was channeled through a six-speed Steptronic automatic transmission, known for its smooth and responsive shifts. The transmission was specifically tuned to complement the V8’s power delivery, offering both automatic and manual shift modes. The xDrive all-wheel-drive system distributed power between the front and rear axles as needed, enhancing traction and stability in various driving conditions.
Driving Characteristics
The 750i xDrive delivered a markedly different driving experience compared to the lower-trim 7 Series models. The abundant torque from the twin-turbo V8 provided effortless acceleration, with a 0-60 mph time of around 4.8 seconds. While not overtly sporty, the 750i offered a confident and composed ride, thanks to the xDrive system and the sophisticated suspension. The automatic transmission’s programming prioritized smooth shifts and comfortable cruising, but also allowed for more aggressive gear changes in Sport mode. Compared to the 740i, the 750i felt significantly more powerful and responsive, particularly during overtaking maneuvers. The 750i also differed from the diesel-powered 730d in its engine character; the V8 offered a more refined and sonorous exhaust note, and a more immediate throttle response.
Equipment & Trim Levels
The 750i xDrive came standard with a comprehensive array of luxury features. Leather upholstery, power-adjustable heated front seats, a premium sound system, and a navigation system were all included as standard equipment. Optional extras included features like massaging seats, a rear-seat entertainment system, adaptive cruise control, and a head-up display. The interior trim could be customized with various wood veneers and metallic accents. The exterior styling was distinguished by unique badging and larger alloy wheels. The 750i generally represented the highest level of standard equipment within the F01 7 Series range, with most optional extras being reserved for further personalization.
Chassis & Braking
The 750i xDrive featured a double-wishbone front suspension and an independent multi-link rear suspension, optimized for both comfort and handling. The suspension was electronically controlled, allowing for adjustments to damping rates based on driving conditions. Ventilated disc brakes were fitted on all four wheels, providing ample stopping power. The ABS (Anti-lock Braking System) and stability control systems worked in conjunction to enhance safety and prevent skidding. The xDrive all-wheel-drive system contributed to improved braking performance, particularly on slippery surfaces.
Market Reception & Comparison
The 750i xDrive was generally well-received by automotive critics, who praised its powerful engine, luxurious interior, and refined driving experience. However, some reviewers noted the car’s considerable weight and its relatively high fuel consumption. Compared to the 740i, the 750i offered a significant performance advantage, but at a higher price point. The 750i’s fuel economy, averaging around 19.8 US mpg in combined driving, was lower than that of the 740i and the 730d. Reliability reports indicated that the N63 engine, while powerful, could be prone to certain issues, such as oil leaks and cooling system problems, requiring diligent maintenance.
Legacy
The F01 750i xDrive remains a desirable luxury sedan in the used car market. While the N63 engine requires careful maintenance, its performance and refinement continue to appeal to enthusiasts. The car’s advanced technology and luxurious features have aged relatively well, making it a competitive option for those seeking a high-end sedan. The F01 generation 7 Series, and particularly the 750i, represents a pivotal moment in BMW’s history, showcasing the brand’s commitment to innovation and luxury. Finding well-maintained examples is key, as preventative maintenance and addressing potential engine issues are crucial for long-term ownership.
