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 encryption is among the toughest in the industry, especially on modern models. Top AMG engines offer significant potential with a downpipe + intake. AMG is Mercedes's performance division (since 1967), acquired by Mercedes in 1999.
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.
