The BMW 740iL, part of the E38 7 Series “Long” wheelbase generation produced from 1998 to 2001, represented a significant evolution in BMW’s flagship sedan. Positioned as a mid-range offering within the E38 lineup – sitting between the 735iL and the high-performance 750iL – the 740iL combined a potent V8 engine with the convenience of BMW’s Steptronic automatic transmission. The “L” designation indicated the extended wheelbase, offering increased rear passenger legroom, a key feature for the American market where the E38 found considerable success. This variant aimed to deliver a balance of luxury, performance, and technology, appealing to buyers seeking a refined and capable grand touring experience.

Powertrain & Engine Architecture
The heart of the 740iL was the M62B44, a 4.4-liter naturally aspirated V8 engine. This engine, a successor to the M60 and M62 families, featured all-aluminum construction, contributing to a reduction in weight compared to its predecessors. It utilized a double overhead camshaft (DOHC) valvetrain with four valves per cylinder, optimizing airflow for increased power and efficiency. Fuel delivery was managed by a multi-port fuel injection system, providing precise fuel metering. The M62B44 produced 286 horsepower at 5400 rpm and 440 Nm (324.53 lb-ft) of torque at 3600 rpm. Paired with this engine was a 5-speed Steptronic automatic transmission, BMW’s branded automatic with a manual shift mode. This transmission offered smooth gear changes and allowed drivers to exert some control over the gear selection, enhancing the driving experience.
Driving Characteristics
The 740iL’s driving experience was characterized by a blend of effortless power and refined comfort. While not as overtly sporty as the 750iL, the 740iL offered ample acceleration, achieving 0-60 mph in approximately 6.7 seconds. The Steptronic transmission, while generally smooth, could sometimes feel slightly hesitant during quick downshifts. Compared to the 6-speed manual transmission available on some 740i models, the automatic prioritized comfort over outright performance. The longer wheelbase of the “L” model contributed to a more stable and comfortable ride, particularly on long journeys. The suspension, tuned for luxury, absorbed bumps effectively, but didn’t offer the same level of body control as the sportier suspension options found on other E38 variants.
Equipment & Trim Levels
The 740iL came standard with a comprehensive list of luxury features, including leather upholstery, power-adjustable front seats with memory function, automatic climate control, a premium sound system, and a sunroof. The extended wheelbase provided generous rear passenger space, making it a popular choice for chauffeur-driven executives. Optional extras included rear seat entertainment systems, upgraded leather options, active suspension, and various driver assistance features. The interior trim could be customized with wood veneers or aluminum accents, allowing buyers to personalize the cabin to their preferences.
Chassis & Braking
The E38 7 Series utilized a robust chassis with independent suspension at all four corners. The front suspension employed a double wishbone design, while the rear featured an integral rear axle. The 740iL was equipped with ventilated disc brakes at the front and solid disc brakes at the rear. Anti-lock braking system (ABS) was standard, enhancing braking performance and stability. The steering was a rack-and-pinion system with hydraulic power assistance, providing precise and responsive steering feel.
Market Reception & Comparison
The 740iL was generally well-received by automotive critics, who praised its comfortable ride, spacious interior, and refined powertrain. It was often seen as a sweet spot in the E38 lineup, offering a good balance of performance and luxury at a more accessible price point than the 750iL. Fuel economy, however, was a common criticism, with the 4.4-liter V8 consuming a significant amount of fuel, especially in city driving. Compared to the 735iL, the 740iL offered a noticeable performance advantage, while the 750iL provided even more power but at a higher cost.
Legacy
The E38 740iL remains a sought-after classic among BMW enthusiasts. The M62B44 engine, while not without its potential maintenance needs (such as valve stem seal leaks), is generally considered a reliable powerplant when properly maintained. The Steptronic transmission, while not as durable as some manual transmissions, can provide years of service with regular fluid changes. Today, well-maintained examples of the 740iL command respectable prices in the used car market, appealing to collectors and drivers who appreciate its blend of luxury, performance, and timeless design. Its influence can be seen in subsequent generations of the 7 Series, which continued to prioritize comfort, technology, and a refined driving experience.
