The BMW M5 E60, with its naturally aspirated V10 engine and distinctive styling, remains a sought-after performance sedan for enthusiasts. However, not all E60 M5 model years are created equal, especially when considering long-term reliability and potential maintenance concerns. For those in the market for a used E60 M5, understanding the nuances between model years can be crucial in making an informed decision.
While earlier models from 2006 and 2007 might be tempting due to potentially lower initial prices, it’s essential to be aware of their documented issues. These years are often cited as being more troublesome, particularly concerning the engine and the Sequential Manual Gearbox (SMG) transmission. The high sales volume of these early years means they are readily available, contributing to a perception of potentially lower resale value compared to later, more refined iterations. Owners and mechanics have reported that the 2006 and 2007 E60 M5s can experience more frequent problems, leading to higher maintenance costs over time.
The 2009 and 2010 model years represent a significant step forward in terms of reliability and refinement for the E60 M5. BMW implemented several key improvements to the V10 engine in these later models. These enhancements included:
- Updated VANOS components: Addressing potential weaknesses in the variable valve timing system.
- Dual Engine Oil Drains: Improving oil drainage and potentially reducing oil sludge buildup.
- Stronger Engine Bolts: Enhancing engine block integrity and durability.
- Piston Oil Squirters: Improving piston cooling and reducing thermal stress.
- Updated Rod Bearings (702/703): Addressing a known weak point in earlier V10 engines and improving engine longevity.
Furthermore, the SMG transmission in the 2009 and 2010 E60 M5 models benefited from the latest hardware and software revisions. This resulted in a noticeably smoother and more responsive driving experience compared to the earlier versions of the SMG system. Many enthusiasts consider the SMG in these later years to be significantly more refined and reliable.
The 2008 model year E60 M5 occupies a middle ground. While it incorporates some improvements over the 2006/2007 models, it may lack some of the critical engine upgrades found in the 2009/2010 versions, such as piston oil squirters and the newer rod bearings. Additionally, the 2008 SMG system is likely to be running older software compared to the final iterations.
For those seeking the most reliable and potentially best long-term value within the E60 M5 range, the 2009 and 2010 models stand out as the most desirable choices. Their enhanced V10 engine and refined SMG transmission contribute to a more robust and enjoyable ownership experience. This increased reliability and the desirability of the later specifications are likely to contribute to a stronger resale value for these model years in the used market.
Beyond performance and reliability, the E60 M5 offers a practical and comfortable cabin. Compared to models like the E90, the E60 provides significantly more room, especially for rear passengers. The generous trunk space further enhances its usability as a daily driver. Even taller occupants will find the E60 M5 comfortable for both short commutes and longer journeys.
When it comes to performance, even in stock form, the BMW M5 E60 is a formidable machine. Modifications can unlock even more power, with some reaching upwards of 500 wheel horsepower. In the most aggressive “S6” mode, the SMG transmission delivers rapid and visceral shifts, contributing to the car’s exhilarating and raw driving character. While the E60 M5’s weight might not make it a dedicated track weapon straight from the factory, its overall driving dynamics are undeniably impressive for a car of its size and class. Anyone who has experienced an E60 M5 can attest to its remarkable blend of power, luxury, and engaging driving dynamics.
