C 63 AMG Wagon W204 vs Audi RS4 Avant B8 Exhaust Sounds

With an entirely new generation of the C 63 AMG nameplate in station wagon guise to arrive in about a year from now, the current Mercedes-Benz C 63 AMG T-Modell S204 (or Estate in certain countries) is still making rounds as having one of the coolest-sounding production engines in recent years.

Internally-codenamed M156, the 6.2-liter naturally-aspirated V8 under the current C 63 AMG hood provides the most eargasmic exhaust sounds this side of a World War II fighter plane.

Sadly, it only has a few more months to live until an all-new, twin-turbocharged four-liter V8 is set to take its place for reasons mostly concerning CO2 emissions.

That kind of gives as a sad, but thankfully there are plenty of M156 exhaust note videos to find on the Internet, and the following is no exception into giving us a short burst of sound-induced adrenaline rush.

The best way to appreciate how the in-house developed 6.2-liter monster stretches its auditory muscles all over its rpm range is to put it up against another legendary V8, whose rev limiter sits over 1000 rpm higher than in the AMG.

Mainly for this reason, the 4.2-liter FSI in the following Audi RS4 Avant (B8) suffers from a severe lack of torque compared to the mammoth M156 in the C 63 AMG Wagon S204, but this is not the only difference between the two naturally-aspirated engines.

The main contrast between them is obviously the amount and most of all the types of sound that their exhausts make, with the Audi emitting a much more muffled down bellow, while the AMG pretty much sounds like a caged tiger being poked with cattle prods. Which one do you prefer?
