The Best Years For Mercedes Benz E63 And Some To Avoid

The Mercedes-Benz E63 AMG (and later Mercedes-AMG E63) represents the pinnacle of performance within the E-Class lineup. Combining luxury with raw power, these models have captivated enthusiasts for years. However, not all E63s are created equal, and understanding the nuances of each generation and model year is crucial before making a purchase.

Mercedes-Benz E63 Generations and Model Years: A Quick Overview

Detailed Explanations

W211 (2007-2009): The First of the Breed - and Potential Pitfalls

The W211 E63 AMG, introduced in 2007, marked a significant shift for the E-Class. It boasted the naturally aspirated 6.2-liter M156 V8 engine, a masterpiece of engineering that produced remarkable power and a distinctive exhaust note. However, this generation also has its share of potential issues.

• M156 Engine Reliability: While powerful and characterful, the M156 engine is known for potential camshaft adjuster (phaser) bolt failures. These bolts can shear off, leading to significant engine damage. Regular inspection and replacement (especially if mileage is high) are strongly recommended. Additionally, lifter tick can be a common issue, especially in the earlier years.
• Air Suspension Issues: The air suspension system on the W211 E63, while providing a comfortable ride, is prone to leaks and compressor failures. Replacing air struts can be costly. Thoroughly inspect the system for any signs of sagging or compressor noise.
• SBC Brakes (2007): The Sensotronic Brake Control (SBC) system, used only in the 2007 model year, can be problematic and expensive to repair. It is an electronically controlled braking system that, while innovative at the time, has proven to be unreliable over time. Many owners prefer to avoid the 2007 model year due to this system.
• Rust Concerns: While not as prevalent as in some older Mercedes models, rust can still be a concern, particularly in areas with harsh winter conditions. Inspect the wheel arches, door bottoms, and undercarriage for any signs of corrosion.
• Fuel Consumption: The naturally aspirated V8 engine is thirsty, so expect relatively low fuel economy, especially during spirited driving.

W212 (2010-2016): Turbocharged Power and Evolving Technology

The W212 E63 AMG saw significant changes throughout its production run. The early models (2010-2011) retained the M156 engine, while the later models (2012-2016) received the turbocharged 5.5-liter M157 V8. This generation also introduced features like 4MATIC all-wheel drive.

• M156 (2010-2011) vs. M157 (2012-2016) Engines: The M156 engine carried over from the W211 in the early W212 models. While it retained its character and sound, the M157 engine offered improved fuel economy and even more power. The M157, however, has its own set of potential issues.
• 4MATIC Availability (2014+): Starting in 2014, the E63 AMG became available with Mercedes' 4MATIC all-wheel-drive system. This significantly improved traction and handling, especially in adverse weather conditions. However, it also added weight and complexity to the vehicle.
• Air Suspension: Similar to the W211, the W212 E63 also features air suspension, which can be susceptible to leaks and failures. Regular maintenance and inspection are crucial.
• Transmission Tuning: The 7-speed MCT (Multi-Clutch Transmission) in the W212 E63 received various tuning updates throughout its production run. The later models generally have smoother and more responsive shifting.
• Early M157 Oil Consumption: Some early M157 engines experienced higher-than-normal oil consumption. This issue was typically addressed with updated piston rings in later models. Check the service history for any evidence of oil consumption issues.

W213 (2017-2023): Modern Performance and Cutting-Edge Technology

The W213 E63/S AMG represents the most modern iteration of the E63. It features the 4.0-liter twin-turbocharged M177 V8 engine, advanced technology, and a sophisticated 4MATIC+ all-wheel-drive system. While generally considered the most reliable, it also comes with higher repair costs due to its complexity.

• M177 Engine Refinement: The M177 engine is a highly refined and powerful engine. It offers excellent performance and responsiveness. While generally reliable, it's crucial to adhere to the recommended maintenance schedule.
• 4MATIC+ AWD System: The 4MATIC+ system is a sophisticated all-wheel-drive system that can vary the torque distribution between the front and rear axles. In "Drift Mode," the car can even send all the power to the rear wheels for controlled drifting.
• Advanced Technology: The W213 E63 is packed with advanced technology, including driver-assistance systems, infotainment features, and performance-enhancing technologies. Familiarize yourself with these systems and their potential maintenance requirements.
• Potential for High Repair Costs: Due to the complexity of the W213 E63, repairs can be expensive. Ensure you have access to a qualified Mercedes-Benz technician.
• Turbocharger Location: The turbos are located inside the "V" of the engine. While this is beneficial for packaging, it also means they are subjected to high temperatures.

Frequently Asked Questions

Which E63 generation is the most reliable?

Generally, the W213 (2017-2023) generation is considered the most reliable due to its more refined engine and advanced technology. However, its complexity can lead to higher repair costs.

What is the biggest issue with the M156 engine?

The most significant concern with the M156 engine is the potential for camshaft adjuster (phaser) bolt failures, which can cause significant engine damage.

Is 4MATIC all-wheel drive worth it on the E63?

Yes, 4MATIC provides significantly improved traction and handling, especially in inclement weather. It enhances the car's usability and confidence in various driving conditions.

Are air suspension problems common on the E63?

Yes, air suspension systems are prone to leaks and compressor failures on both the W211 and W212 generations. Regular maintenance and inspection are essential.

What should I look for when buying a used E63?

Thoroughly inspect the car's service history, check for signs of rust or damage, and have a pre-purchase inspection performed by a qualified Mercedes-Benz technician. Pay close attention to the engine, transmission, and suspension.

Conclusion

Choosing the best year for a Mercedes-Benz E63 depends on your priorities and budget. The W211 offers raw, naturally aspirated power but requires careful inspection due to potential reliability concerns. The W212 provides a balance of performance and technology, while the W213 represents the most modern and refined option, albeit with potentially higher repair costs. Thorough research and a pre-purchase inspection are crucial before making a decision.
