Which AMG is the Loudest?

The sound of an AMG is legendary. The throaty rumble, the aggressive snarl, and the crackling overrun are all hallmarks of Mercedes-AMG's commitment to performance and driving pleasure. But which AMG model reigns supreme in the decibel department? This article delves into the quest for the loudest AMG, exploring various factors that contribute to its auditory dominance and providing a comprehensive comparison of several contenders.

The Contenders: A Comparative Table

Detailed Explanations

C63 S (W205) (2015-2021): The W205 C63 S is renowned for its raw and unadulterated V8 sound. Its optional performance exhaust system, equipped with valve control, allows drivers to switch between a more subdued tone for everyday driving and a roaring, aggressive sound for spirited performance. The characteristic pops and crackles on overrun are a signature of this model.

E63 S (W213) (2018-2023): Sharing the same engine as the C63 S, the E63 S delivers a similar auditory experience, albeit with a slightly more refined edge. The AMG Performance Exhaust system offers a deep V8 rumble accompanied by prominent pops and burbles, creating a powerful and authoritative presence on the road.

GT 63 S 4-Door Coupe (X290) (2019-Present): The GT 63 S 4-Door Coupe is often considered the loudest stock AMG currently available. Its exhaust note is exceptionally aggressive, characterized by pronounced pops, crackles, and burbles that amplify the distinctive V8 roar. The sheer volume and intensity of the sound contribute to its dominant auditory presence.

SL 63 (R232) (2022-Present): The R232 SL 63 aims for a balance between performance and luxury. While still equipped with a potent V8 and the optional AMG Performance Exhaust system, its sound is tuned to be slightly more refined than the GT 63 S. It offers a deep V8 rumble with distinct pops and crackles, but prioritizes a more comfortable and controlled auditory experience.

A45 S (W177) (2019-Present): Despite its smaller engine, the A45 S is surprisingly loud and aggressive. The high-revving, turbocharged 4-cylinder engine produces a unique sound, further enhanced by the optional AMG Performance Exhaust system. The aggressive pops and bangs create an exciting and engaging driving experience, defying expectations for its engine size.

G63 (W463) (2018-Present): The G63's exhaust note is truly unique, thanks to its throaty V8 rumble and the optional side-exit exhaust system. This configuration amplifies the sound, creating an unmistakably aggressive and imposing presence. The G63's sound is as distinctive as its iconic design.

S63 (W223) (2023-Present): The S63 prioritizes luxury and refinement. While still equipped with a V8 engine and offering the optional AMG Performance Exhaust system, its sound is tuned to be less aggressive than other AMG models. The S63 offers a refined V8 rumble with some pops and crackles, but ultimately leans towards a more subdued and sophisticated auditory experience.

CLS 63 S (W218) (2011-2018): This generation of CLS 63 S is considered by many to have one of the best sounding AMG engines ever made. With its classic AMG V8 sound, deep rumble and aggressive pops, especially with the optional performance exhaust.

Factors Contributing to Loudness:

• Engine Configuration: V8 engines are inherently louder than smaller engines due to their larger displacement and firing order.
• Exhaust System Design: The design of the exhaust manifold, catalytic converters, resonators, and mufflers significantly impacts the sound. Performance exhaust systems are typically less restrictive, allowing for greater volume and a more aggressive tone.
• Valve Control: Many AMG models feature exhaust valves that can be opened or closed to adjust the sound level. When the valves are open, the exhaust gases bypass the mufflers, resulting in a louder and more aggressive sound.
• Turbocharging: While turbocharging can muffle the exhaust sound to some extent, AMG engineers have developed strategies to maintain a distinctive and engaging sound, often through carefully tuned exhaust systems and electronic sound enhancement.
• Side-Exit Exhausts: As seen on the G63, side-exit exhausts significantly amplify the sound by shortening the path the exhaust gases travel, reducing muffler effectiveness.

Frequently Asked Questions

• Which AMG has the loudest exhaust from the factory? The GT 63 S 4-Door Coupe is generally considered the loudest stock AMG due to its aggressive exhaust system and pronounced pops and crackles.

• Does the AMG Performance Exhaust make a big difference? Yes, the AMG Performance Exhaust system significantly enhances the sound of most AMG models, resulting in a louder, more aggressive, and more engaging driving experience.

• Can I make my AMG louder? Yes, aftermarket exhaust systems and other modifications can further enhance the sound of your AMG. However, be sure to comply with local noise regulations.

• Are newer AMGs quieter than older ones? Generally, yes. Due to increasing emissions regulations and sound restrictions, newer AMGs tend to be slightly quieter than older models, although AMG continues to strive for an engaging and distinctive sound.

• Do the different driving modes affect the exhaust sound? Yes, in most AMG models, selecting a sportier driving mode will open the exhaust valves, resulting in a louder and more aggressive sound.

Conclusion
