Mercedes-Benz Chassis Codes (1990–2026)

What is a Mercedes-Benz chassis code? Mercedes names every generation and body style with a chassis code : a letter and three digits such as W205 or X253 . The letter is the body: W for sedans (and some SUVs), S for wagons, C for coupes, A for convertibles, R for roadsters, X for SUVs and the GT 4-Door. The digits are the generation, so a C-Class sedan is a W204, W205 or W206. The code tells a tuner which ECU, transmission and calibration a car has. Which Mercedes chassis does AMR Performance tune?

Confirm against your VIN. How to find your Mercedes chassis code VIN: characters 4–9 of a Mercedes VIN carry the model code, and AMR can confirm the chassis and engine from it. Engine too: one chassis carries different engines (a W205 C300 is a 2.0T four, a C43 a 3.0 biturbo V6, a C63 a 4.0 biturbo V8), and the tune follows the engine. Looking to tune your Mercedes?
