BMW 540i 2003-2010 Specifications

The 2003-2010 BMW 540i is equipped with a 4.4L V8 engine producing 282 horsepower and 324 lb-ft of torque. Compared to the 525i and 530i models, the 540i offers significantly higher power and torque, making it a more performance-oriented option. The 540i's engine is also paired with advanced technologies like Double-VANOS variable valve timing and Valvetronic for improved efficiency and responsiveness.

The BMW 540i is available with a 6-speed manual transmission or a 6-speed automatic transmission (Steptronic). The manual transmission offers a more engaging driving experience, while the automatic transmission provides smooth shifts and optional sport mode for enhanced performance.

Standard safety features include dual front airbags, side airbags, ABS, traction control, and dynamic stability control (DSC). Optional features include adaptive headlights, a head-up display, and a rearview camera. The 540i also features advanced crumple zones and a reinforced passenger cabin for enhanced crash protection.

The 540i achieves an EPA-estimated 16 mpg in the city and 24 mpg on the highway, which is competitive with other V8-powered luxury sedans of the same era, such as the Mercedes-Benz E500 and Audi A6 4.2. However, it is less efficient than smaller-engine competitors like the BMW 530i.

BMW recommends an oil change every 7,500 to 10,000 miles under normal driving conditions. Other key maintenance intervals include inspecting the brake system every 15,000 miles, replacing the air filter every 30,000 miles, and changing the coolant every 60,000 miles. Regular inspections of the suspension, tires, and fluid levels are also advised.

Standard features include leather upholstery, dual-zone automatic climate control, power-adjustable front seats, and a premium sound system. Optional features include navigation, a sunroof, adaptive cruise control, and the M Sport package, which adds sport-tuned suspension, upgraded wheels, and unique styling elements.

The 540i offers 13.5 cubic feet of trunk space, which is comparable to the Mercedes-Benz E500 but slightly less than the Audi A6. The interior provides ample legroom and headroom for both front and rear passengers, making it a comfortable option in its class.

The BMW 540i is not officially rated for towing in most markets. However, it has a payload capacity of approximately 950 pounds, which is typical for a luxury sedan of its size and class.
