Stage 1 chip tuning raises power from 360 to 378 hp (+18 hp, +5%) and torque from 530 to 560 Nm (+30 Nm). ECU — Bosch ME2.8. Flashing method: OBD or Bench depending on the unit's protection.

Mercedes-Benz is the world's oldest carmaker, founded in 1926 by the merger of Daimler-Motoren-Gesellschaft and Benz & Cie. The Mercedes slogan is 'Das Beste oder nichts' ('The best or nothing'). Smart is Mercedes's city sub-brand, historically running Mitsubishi and Renault engines. The Mercedes petrol range spans compacts, premium saloons, SUVs, roadsters and AMG flagships. Brabus is an independent Mercedes tuning house specialising in top-model upgrades. The factory calibration on Mercedes petrol engines is conservative, leaving headroom for Stage 1.
Mercedes is one of the most protected brands in the chip tuning industry in terms of encryption. The Mercedes community in Europe has a large pool of available Stage files for the standard models. AMG engines confidently reach Stage 2 with a downpipe + intake. Top AMG engines sit at the Mercedes power ceiling, and the gain is significant. AMG engines are a well-known base once hardware is added (downpipe + intake + intercooler). Brabus is a premium alternative to AMG for the top models. AMG Performance Studio is Mercedes's in-house tuning studio for bespoke projects.
