Detailed Explanations
E38 (1995-2001): The Classic Choice
The E38 740 is often considered a sweet spot for BMW enthusiasts. It boasts a classic, elegant design and a robust M62 V8 engine. However, pre-1999 models are known for timing chain guide issues, which can be costly to repair. Cooling system problems are also common due to the age of the components. While generally reliable for its age, be prepared for potential electronic glitches, as these cars are now over two decades old. A well-maintained E38 740 offers a blend of luxury and driver engagement that is hard to find in modern cars.
E65/E66 (2002-2008): A Technological Leap (and Potential Headache)
The E65 (standard wheelbase) and E66 (long wheelbase) 740 introduced the controversial "Bangle Butt" design and the revolutionary iDrive system. Powered by the N62 V8 engine, these models offered impressive performance. Unfortunately, the N62 is prone to valve stem seal failures, leading to excessive oil consumption and smoky exhaust. Coolant leaks are also a frequent issue. The complex electronics of the E65/E66 can be challenging to diagnose and repair, making them potentially expensive to own. While innovative, this generation is often cited as one to approach with caution unless you have a very well-maintained example and are prepared for potential maintenance costs.
F01/F02 (2009-2015): Refinement and Performance
The F01 (standard wheelbase) and F02 (long wheelbase) 740 represented a significant step forward in terms of design and technology. Engine options included the N54 and N55 inline-6 turbocharged engines, as well as the N63 V8. The N63 engine, while powerful, is notorious for oil consumption issues and potential turbocharger problems. The N54, while a performance powerhouse, is known for high-pressure fuel pump (HPFP) failures. Despite these potential issues, the F01/F02 offers a more refined driving experience and a more user-friendly iDrive system than its predecessor. Look for examples with documented service history and consider a pre-purchase inspection.
G11/G12 (2016-2022): Modern Luxury and Innovation
The G11 (standard wheelbase) and G12 (long wheelbase) 740 introduced a carbon core structure, enhancing rigidity and reducing weight. Engine options included the B58 inline-6 and the updated N63 V8. These models are packed with advanced technology and offer a luxurious and comfortable ride. Potential issues include air suspension problems and software glitches. The complex systems require specialized mechanics for diagnosis and repair. While generally more reliable than the E65/E66 and F01/F02 generations, the G11/G12 can still be expensive to maintain due to its advanced technology.
G70 (2023-Present): A Bold New Direction
The G70 740 represents a radical departure in terms of design and technology. It features a bold new exterior and a completely redesigned interior. Engine options include the B58 inline-6 and the S68 V8 (in the M760e). A fully electric i7 variant is also available. As a new model, the long-term reliability of the G70 is still unknown. The high initial cost and polarizing aesthetics may also be factors to consider. Being the latest generation, it benefits from the newest technology and safety features, but expect higher repair costs should issues arise.
Frequently Asked Questions
Which BMW 740 is the most reliable?
The E38 (1995-2001) and G11/G12 (2016-2022) generations are generally considered the most reliable, although the E38 will require more age-related maintenance. The G11/G12 offers modern technology and improved reliability compared to the E65/E66 and F01/F02.
What are the common problems with the BMW 740?
Common problems vary by generation, but include timing chain guide issues (E38), valve stem seal failures (E65/E66), oil consumption (N63 engine), and air suspension problems (G11/G12). Electronic issues are also a common concern across all generations.
How much does it cost to maintain a BMW 740?
Maintenance costs can be significant, especially for older models and those with complex systems. Expect to pay more for repairs than with a more mainstream vehicle.
