Mercedes C (2021 - W206) 400e Hybrid (2.0) 381 hp — premium hybrid engine of the passenger segment of the Mercedes-Benz Group AG (Mercedes-Benz, AMG, Maybach, Smart, EQ) group (Германия, 1926). Stage 1 chip tuning raises power from 381 to 404 hp (+23 hp, +6%) and torque from 700 to 770 Nm (+70 Nm).

Mercedes is one of the most protected brands in the chip tuning industry in terms of encryption. Maybach is Mercedes's ultra-luxury sub-brand. Mercedes-Benz is the world's oldest carmaker, founded in 1926 by the merger of Daimler-Motoren-Gesellschaft and Benz & Cie. Mercedes EQ is a dedicated full-EV line. AMG E-Performance is a range of hybrid AMG models with an F1-derived electric system. The F1 heritage in AMG hybrid powertrains (Project ONE) comes with a locked electronic architecture.

The Mercedes community in Europe has a large pool of available Stage files for the standard models. Stage 1 on Mercedes often requires refreshing the adaptations after the flash. On modern Mercedes, the encryption requires specialised Bench tools. AMG Performance Studio is Mercedes's in-house tuning studio for bespoke projects. Bench reading is a mandatory procedure for modern AMG models. 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).
