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. Karl Benz is credited as the inventor of the automobile with the 1886 Patent-Motorwagen. The factory calibration on Mercedes petrol engines is conservative, leaving headroom for Stage 1. Mid-range Mercedes turbo petrol engines are a mainstream Stage 1 subject. On older-generation Mercedes petrol engines, Stage 1 is flashed over OBD without Bench.
The Mercedes community in Europe has a large pool of available Stage files for the standard models. Stage 1 on standard mid-range Mercedes petrol engines delivers a noticeable gain. The AMG community is active in Germany, but the protection is the toughest in the industry, so Stage 1 on AMG usually requires Bench.
