Powertrain & Engine Architecture
The heart of the 745i is the N62B44, a 4.4-liter naturally aspirated V8 engine. This engine represented a significant departure from BMW’s previous V8 designs, featuring all-aluminum construction, double overhead camshafts (DOHC) with four valves per cylinder, and a relatively high 10:1 compression ratio. The N62 utilized a multi-port fuel injection system, delivering fuel directly into the intake ports. The engine produced 333 horsepower at 6100 rpm and 331.9 lb-ft of torque at 3600 rpm. Paired with the engine was a six-speed Steptronic automatic transmission, BMW’s branded automatic gearbox offering both fully automatic operation and manual shift control via steering wheel-mounted paddles or the gear selector. The Steptronic transmission was tuned for smooth shifts and responsive performance, complementing the V8’s power delivery.
Driving Characteristics
The 745i’s driving experience was characterized by a smooth and refined ride, coupled with strong acceleration. The 4.4-liter V8 provided ample power for effortless highway cruising and confident passing maneuvers. While not as overtly sporty as some of BMW’s other offerings, the 745i offered a satisfying level of engagement for a full-size luxury sedan. The Steptronic transmission, while generally smooth, could occasionally exhibit some hesitation during downshifts. Compared to the 735i, the 745i offered a noticeable performance advantage, with quicker acceleration and a more authoritative feel. However, it lacked the ultimate performance of the range-topping 760i, which featured a V12 engine.
Equipment & Trim Levels
The 745i came standard with a comprehensive list of luxury features, including leather upholstery, power-adjustable heated front seats, a premium sound system, automatic climate control, and a sunroof. Available options included rear-seat entertainment, active suspension, massaging seats, and a navigation system. Interior trim options ranged from wood veneers to aluminum accents, allowing buyers to personalize the cabin to their tastes. The standard dashboard configuration featured analog gauges with a central information display, providing information on vehicle settings, audio controls, and navigation guidance.
Chassis & Braking
The E65 7 Series featured a robust chassis with a multi-link rear suspension designed to provide a comfortable ride and precise handling. The 745i utilized ventilated disc brakes on all four wheels, providing ample stopping power. Anti-lock braking system (ABS) was standard, enhancing safety and stability during emergency braking situations. The steering system was a hydraulic rack-and-pinion setup, offering precise and responsive steering feel. The suspension was tuned to prioritize comfort, but still provided a reasonable level of control in corners.
Market Reception & Comparison
The 745i was generally well-received by automotive critics, who praised its powerful engine, refined ride, and advanced features. However, some reviewers criticized the E65 7 Series’ complex iDrive infotainment system, which was often described as unintuitive and distracting. Compared to its competitors, such as the Mercedes-Benz S-Class and the Audi A8, the 745i offered a more driver-focused experience. Fuel economy was reasonable for a V8-powered luxury sedan, but not exceptional. Reliability proved to be a mixed bag, with some owners reporting issues with the cooling system and electronic components.
Legacy
The E65 745i remains a desirable used car for enthusiasts seeking a blend of luxury, performance, and technology. While the iDrive system can be a source of frustration, the N62 V8 engine is generally considered to be reliable, provided it has been properly maintained. Common maintenance items include regular oil changes, coolant flushes, and inspection of the cooling system components. Today, the E65 745i represents a unique chapter in BMW’s history, showcasing the automaker’s commitment to innovation and driving pleasure in the full-size luxury segment. Its relatively affordable price point on the used market makes it an attractive option for those seeking a high-end sedan without the premium price tag of newer models.
