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. 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.
On Mercedes up to the recent generation, Stage 1 OBD flash is available. AMG engines confidently reach Stage 2 with a downpipe + intake. Mercedes is one of the most protected brands in the chip tuning industry in terms of encryption. 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.
