C55 AMG W203

The C55 AMG, launched in 2004, represents a pivotal moment in the AMG lineup, transitioning from the supercharged engines of earlier models to naturally aspirated V8 power. As the final AMG variant of the W203 C-Class, it succeeded the C32 AMG and became a standout for its blend of performance and sophistication.

• Engine and Performance: The C55 AMG is powered by a naturally aspirated 5.4-liter V8, generating 362 horsepower and 376 lb-ft of torque. With a 0-60 mph time of 4.7 seconds, it delivers impressive acceleration, despite not having the largest engine in AMG’s arsenal at the time.

• Driving Dynamics: Featuring a rear-wheel-drive layout and a 5-speed automatic transmission, the C55 provided an engaging yet refined driving experience. Its V8 engine delivers a satisfying roar, and the agile handling of the C-Class chassis made it a go-to for enthusiasts seeking both power and compact performance in a luxury sedan.

• Popularity: Although it wasn't produced in large quantities, the C55 AMG has become a favorite among collectors and performance enthusiasts. Its understated styling, paired with raw V8 power, makes it particularly desirable. Notably, it holds the distinction of being the last AMG C-Class model to feature a naturally aspirated engine before Mercedes moved to turbocharging.

• Performance Parts: The C55 has a strong aftermarket following, with some of the most popular performance upgrades including long tube headers and ECU tuning. When fitted with MBH long tube headers and a proper tune, enthusiasts have reported gains of 50 to 60 wheel horsepower over the stock setup. Further power can be unlocked with performance air intakes, and some have even added a supercharger for more extreme performance.

The C55 AMG remains a beloved option for those seeking a balance of classic V8 power and modern driving dynamics, with plenty of room for performance upgrades.
