Detailed Explanations
W204 (2008-2015)
The W204 C63 AMG is arguably the most iconic generation. Its 6.2L naturally aspirated V8 (M156 engine) is a masterpiece, delivering a spine-tingling exhaust note and immediate throttle response that is unmatched by its turbocharged successor. The hydraulic steering provides excellent feedback, making it a driver's car in the truest sense. The pre-facelift models (2008-2011) are often favored for their simpler electronics, which can be easier and less expensive to maintain. You could get it as a sedan, coupe or wagon.
However, the early W204 C63s (2008-2011) are notorious for head bolt issues. These bolts can corrode and break, leading to coolant leaks and potentially catastrophic engine damage. While not every car will experience this problem, it's a significant risk. The optional limited-slip differential (LSD) is highly desirable, significantly improving traction and handling. Be prepared for high running costs, including fuel consumption, tire wear, and brake replacements. Direct injection can lead to carbon buildup on the intake valves, requiring periodic cleaning.
W204 Facelift (2012-2015)
The facelifted W204 C63 AMG (2012-2015) received updated interior and exterior styling, giving it a more modern look. The most significant change was the introduction of the MCT (Multi Clutch Technology) transmission. This transmission uses a wet clutch pack instead of a traditional torque converter, resulting in faster and more direct shifts. Fuel economy was also slightly improved. The W204 Facelift also came as a sedan, coupe or wagon.
While the head bolt issue was less prevalent in the facelift models, it's still a potential concern, particularly in earlier production years. The LSD remained an optional extra. Running costs remain high, and carbon buildup is still a possibility.
W205 (2015-2023)
The W205 C63 AMG marked a significant departure from its predecessor, adopting a 4.0L twin-turbo V8 (M177 engine). This engine delivers even more power and torque, resulting in blistering acceleration. The electronically assisted steering offers a lighter feel, although some enthusiasts miss the directness of the hydraulic steering in the W204. The W205 came with more modern technology and features, including advanced driver-assistance systems. The W205 was available as a sedan, coupe or convertible, but not as a wagon in the US market.
Turbo lag is noticeable at low RPMs, a characteristic inherent to turbocharged engines. The M177 engine has been known to experience oil leaks from the turbo seals. The complex electronics in the W205 can be prone to issues, and repairs can be expensive. Later model years of the W205 tend to depreciate more quickly than the earlier W204 models.
Frequently Asked Questions
Question: Which C63 AMG has the best sound?
Answer: The W204 C63 AMG with the 6.2L naturally aspirated V8 is widely considered to have the best and most iconic exhaust note. Its raw and aggressive sound is unmatched by the turbocharged V8 in the W205.
Question: Are head bolt issues a problem in all W204 C63s?
Answer: No, the head bolt issue is most prevalent in the 2008-2011 models. While less common in the 2012-2015 facelift models, it's still a potential concern.
Question: Is the W205 C63 AMG more reliable than the W204?
Answer: Not necessarily. While the W204 has the potential head bolt issue, the W205 has its own set of potential problems, including turbo seal leaks and complex electronics.
Question: Should I buy a C63 AMG without a limited-slip differential?
Answer: While not essential, the LSD significantly improves handling and traction, especially during spirited driving. It's highly recommended if you plan on tracking the car or driving it aggressively.
Question: What are the running costs like for a C63 AMG?
Answer: Expect high running costs, including fuel consumption, tire wear, brake replacements, and regular maintenance. These cars are performance machines and require premium upkeep.
Conclusion
Choosing the best C63 AMG depends on your priorities. The W204 (particularly the 2012-2015 facelift models if the head bolts have been addressed or replaced) offers the most engaging driving experience with its naturally aspirated V8 and hydraulic steering. The W205 provides more modern technology and increased power, but with the trade-offs of turbo lag and more complex electronics. Thorough research, a pre-purchase inspection, and understanding the potential issues are crucial before making a decision.
