Powertrain & Engine Architecture
The heart of the 540i Steptronic is the N62B40 engine, a 4.0-liter naturally aspirated V8. This engine is characterized by its smooth power delivery and distinctive V8 sound. It utilizes a cast aluminum block and cylinder heads, featuring double overhead camshafts (DOHC) and four valves per cylinder. The N62 engine employed BMW’s Double-VANOS variable valve timing system on both intake and exhaust camshafts, optimizing performance and efficiency across the rev range. Fuel delivery is managed by a multi-port fuel injection system. The six-speed Steptronic automatic transmission, a crucial component of this variant, offered both fully automatic operation and manual shift control via steering wheel-mounted paddles or the gear selector. This transmission was known for its smooth shifts and responsiveness, contributing to the overall refined driving experience.
Driving Characteristics
The 540i Steptronic delivered a noticeably different driving experience compared to the lower-powered 530i and 535i models. The V8 engine provided ample torque throughout the rev range, resulting in strong acceleration and effortless cruising. While the 0-60 mph time of around 6 seconds wasn’t groundbreaking by modern standards, the engine’s linear power delivery and the smooth operation of the Steptronic transmission made for a relaxed and confident driving experience. Compared to the six-cylinder variants, the 540i felt more planted and stable, particularly at higher speeds. The automatic transmission, while offering convenience, did slightly diminish the sense of driver engagement compared to the available six-speed manual transmission.
Equipment & Trim Levels
The 540i Steptronic typically came well-equipped as standard. Interior features included leather upholstery, power-adjustable front seats with memory function, automatic climate control, and a premium sound system. BMW’s iDrive infotainment system was standard, though its early iterations were often criticized for their complexity. Optional extras included a navigation system, upgraded leather options, a sunroof, and active suspension. The 540i was often specified with the Sport Package, which added sport seats, a sport suspension, and unique exterior trim elements. The overall interior ambiance was one of understated luxury, with high-quality materials and meticulous attention to detail.
Chassis & Braking
The E60 5 Series featured a sophisticated chassis design, utilizing a multi-link rear suspension for improved ride comfort and handling. The 540i, due to its higher weight, often featured slightly stiffer springs and dampers compared to the four-cylinder models. Braking duties were handled by disc brakes on all four wheels, with ABS (Anti-lock Braking System) standard. The braking system provided ample stopping power, though some reviewers noted a slightly soft pedal feel. The standard tire size was 225/50 R17, providing a good balance of grip and ride comfort.
Market Reception & Comparison
The 540i Steptronic was generally well-received by automotive critics, who praised its powerful engine, refined ride, and luxurious interior. However, the iDrive system was a common point of criticism. Compared to the 530i and 535i, the 540i offered a significant performance upgrade, but at a higher price point. Fuel economy was predictably lower than the six-cylinder models, averaging around 18 mpg in combined driving. Reliability was generally good, though the N62 engine was known to be susceptible to coolant leaks and oil consumption issues as it aged.
Legacy
Today, the E60 540i Steptronic represents an interesting proposition in the used car market. Its V8 engine and luxurious features make it an appealing choice for enthusiasts seeking a comfortable and capable grand tourer. However, potential buyers should be aware of the potential maintenance costs associated with the N62 engine, particularly regarding coolant leaks and oil consumption. Well-maintained examples are becoming increasingly collectible, and the 540i’s blend of performance, luxury, and relative rarity ensures its place as a desirable variant within the E60 5 Series lineage.
