C63 AMG
Overview
The W204 C63 AMG is powered by the naturally aspirated M156 6.2L V8, a hand-built engine producing 451 hp (481 hp in the Edition 507). It was the last C-Class AMG with a naturally aspirated engine and is revered for its raw, visceral driving experience and one of the greatest exhaust notes in automotive history. Available as sedan, coupe, and wagon (in some markets), the C63 represents the purest expression of AMG philosophy in the modern era.

Beach Benz Experience
“The M156 C63 is one of the most thrilling cars we work on. We proactively inspect head bolts and cam adjusters on every service. Early cars (2008-2010) are most susceptible to head bolt issues. We always recommend upgraded head bolts during any head-off repair. This engine deserves a specialist.”
