Mercedes-AMG C63 S

Lore & Background

In the Forza universe, the C63 S occupies a very particular niche: the aspirational commuter. It's the car a character might pull up to a café in a quiet town, engine still warm from a spirited run down a coastal road, before casually mentioning they just lapped a circuit on the way. It carries the quiet confidence of a German luxury badge while hiding a screaming V8 under the bonnet, and that duality is exactly what makes it resonate with players who want performance without the pretension of a supercar.

Across the various Forza titles, the C63 S has been a reliable presence in the D-class sedan bracket. It's not the outright speed king—that honour often goes to more exotic entries—but its broad power band, predictable handling, and availability of tuning parts make it a favourite for players who enjoy dialling in a setup rather than just holding the throttle. Community build threads and in-game leaderboards frequently feature C63 S entries that have been pushed well beyond factory spec, proving that a well-tuned sedan can keep pace with far flashier machinery.

The car's cultural footprint in the franchise is also tied to its sound. The deep, muscular bark of the V8, especially with the exhaust note amplified by in-game audio design, gives it a presence on the track that lighter, higher-revving engines simply don't match. It's the car that makes a quiet backroad feel like a scene from a heist movie, and that's a feeling the Forza world is built to deliver.

In Their Own Story

Rain still beaded on the asphalt of the coastal highway as the C63 S crested the final rise, its V8 growling a low, satisfied note. The driver had taken the back roads to the circuit—no GPS, no shortcuts, just the rhythm of the engine and the salt-tang of the sea air. Down the other side, the track stretched out under a bruised violet sky, empty except for the distant hum of a single rival car on the far straight. The C63 S dropped its nose, gripped, and launched into the first corner with a confidence that felt almost personal, as if the car knew exactly where the apex was before the driver did. Two laps later, the rain had stopped, the air was clearing, and the V8 was singing in a register that made the whole coastline feel like it belonged to them.

Reader's Guide

The Mercedes-AMG C 63 S (W205 generation, 2015 onward) sits in the D class as a rear-wheel-drive, four-door sedan. Out of the box it produces roughly 510 horsepower from its twin-turbo V8, tips the scales around 1,750 kg, and handles with a balanced, slightly nose-light feel that rewards smooth inputs over aggressive corrections. It's quick—really quick—but not the sharpest cornering tool in its bracket, which is exactly where tuning comes in.

Your main levers are familiar: you can swap to stickier compound tyres to claw back grip in fast corners, stiffen the suspension to reduce body roll, and upgrade brakes to manage the extra speed you'll be generating. The engine bay offers power upgrades that push output well past the factory figure, and a lighter flywheel or revised final-drive ratio can sharpen the throttle response. Body aero kits add downforce at the cost of a small drag penalty, useful on high-speed straights and long corners. Weight reduction parts shave kilograms here and there, helping the car rotate more freely.

The trade-off is predictability versus peak performance. Push the power too hard and the rear end gets twitchy, especially in the wet. Go too far on aero and you lose top-end speed. The sweet spot is usually a moderate power bump, a grip-focused tyre choice, and a suspension setup that keeps the rear planted without killing the car's natural composure.

Build philosophy: respect the V8's low-end shove, keep the chassis honest, and let the car's effortless torque do the work rather than fighting it with over-aggressive tuning.

Did You Know?

• The C63 S's V8 is hand-assembled by a single engineer at the AMG facility, a tradition that has carried over into the car's reputation for individuality and craftsmanship.
• In several Forza titles, the C63 S's exhaust note is one of the most distinctive and layered in the D-class sedan pool, making it a popular choice for players who enjoy the audio experience as much as the driving.
• Despite being a four-door sedan, the C63 S's 0-to-100 km/h time in the real world is competitive with several dedicated two-door sports cars, a fact that the Forza games faithfully reflect in its acceleration figures.
• The 'S' in C63 S stands for 'Sport,' denoting the higher-output variant, and in Forza games this typically translates to a meaningful power bump over the non-S C63, making it the go-to choice for players wanting maximum
