When it comes to the C63 AMG, performance and handling are two of the most important factors that make this car so sought after.

Let’s take a closer look at how this car performs and handles on the road.

Power and Torque

The C63 AMG is powered by a 6.2-liter V8 engine that produces up to 451 horsepower and 443 lb-ft of torque.

If you opt for the 507 Edition or the Black Series, you can get even more power, with up to 510 horsepower and 457 lb-ft of torque. This extra power translates to faster acceleration and higher top speeds, making the car an absolute thrill to drive.

Limited Slip Differential

One of the key features that sets the C63 AMG apart from other sports cars is its limited-slip differential.

This is especially useful when accelerating out of corners or on slippery roads. The limited-slip differential is standard on all C63 AMG models, including those with the Performance Package.

The Mighty M156 Engine

If you own a C63 AMG, you know that the M156 engine is a beast. This 6.2L V8 engine is capable of producing up to 451 hp and 443 lb-ft of torque. However, with great power comes great responsibility.

The M156 engine has a few common problems that you need to be aware of to keep your car running smoothly.

Engine Design

The M156 engine is a complex piece of machinery. It has four valves per cylinder and a variable valve timing system.

The camshafts, lifters, and bearings are all designed to handle the high-revving nature of the engine. However, this design also means that the engine is more susceptible to wear and tear.

Improperly Heat-Treated Components

One of the most common problems with the M156 engine is improperly heat-treated components. The engine has a few soft metal components that are prone to wear and tear.

If these components are not heat-treated properly, they can fail prematurely. This can lead to engine failure and costly repairs.

Design Changes and Upgrades

Mercedes-Benz has made a few design changes and upgrades to the M156 engine over the years. These changes were made to address some of the common problems with the engine.

For example, the head bolts were upgraded to prevent head gasket failure. The lifters were also upgraded to prevent premature wear.

Reliability and Repair Costs

Warranty and Recall Issues

Additionally, there have been several recalls issued for the C63 AMG in recent years. These recalls have addressed issues with the engine cooling system, fuel system, and airbag system, among others.
