Detailed Explanations
Engine (5.4L Supercharged V8 - M113K): The heart of the CLS55 AMG is the legendary M113K engine. This hand-built, supercharged 5.4-liter V8 delivers impressive power and torque, providing exhilarating acceleration. Its robust design is known for its durability, but requires diligent maintenance to avoid issues like oil leaks and supercharger problems.
Horsepower/Torque (469 hp / 516 lb-ft): This figure represents the peak power and rotational force the engine produces. The CLS55's abundant torque makes it incredibly responsive at any speed, while the high horsepower ensures strong performance at higher RPMs.
Transmission (5-Speed Automatic - 722.6): The 722.6 transmission, a robust 5-speed automatic, handles the engine's power effectively. It is generally reliable, but regular fluid changes are critical to prevent slipping and other issues. Some enthusiasts find it less engaging than more modern transmissions, but its durability is a strong point.
Air Suspension (Airmatic): The Airmatic suspension system provides a comfortable ride and allows for adjustable ride height. However, it is a common source of problems in older CLS55 AMGs. Air struts can leak, compressors can fail, and the system's control module can malfunction, leading to expensive repairs.
AMG High-Performance Braking System: The CLS55 AMG features a high-performance braking system designed to provide strong stopping power. Check for rotor wear and ensure the brake pads are in good condition. Regular brake fluid flushes are also essential for optimal performance and longevity.
Interior Features: The CLS55 AMG boasts a luxurious interior with leather upholstery, a premium sound system, and navigation. Check for wear and tear on the seats and ensure all electronic features are functioning properly.
Exterior Features: The AMG body styling, quad exhaust, and alloy wheels give the CLS55 AMG a distinctive and aggressive look. Inspect the body for any signs of damage or rust, and check the condition of the wheels and tires.
Common Issues: The CLS55 AMG is prone to certain common issues, including Airmatic suspension failures, SBC (Sensotronic Brake Control) pump failures, and engine oil leaks. Addressing these issues promptly is crucial to maintaining the car's reliability and performance.
Reliability Rating (Out of 5): This rating is a general indication of the CLS55 AMG's overall reliability, with 5 being the most reliable. While the CLS55 AMG is a well-engineered car, its age and complex systems mean that it requires regular maintenance and is prone to certain issues. A rating of 3.5 reflects the potential for problems, but also the car's inherent robustness when properly cared for.
Maintenance Costs: Owning a CLS55 AMG comes with high maintenance costs. AMG parts can be expensive, and specialized knowledge is often required for repairs. Budget accordingly for regular maintenance and potential repairs.
Notable Improvements Over Previous Years: The 2006 model year benefited from some minor improvements and refinements compared to the initial 2005 release. Early production kinks were typically addressed by this point.
Years to Consider:
- 2006: The 2006 model year is generally considered the best choice due to the aforementioned refinements and improvements.
- 2005: If you can find a well-maintained example, the 2005 model year can also be a good option. However, be prepared for potential early production issues.
- 2004 (Pre-Production): These models should generally be avoided due to their pre-production status and potential for unresolved issues.
Estimated Price Range (USD): This is an approximate price range based on the car's condition, mileage, and location. Prices can vary significantly depending on these factors. Always have a pre-purchase inspection performed by a qualified mechanic before buying a CLS55 AMG.
