Karl Benz is credited as the inventor of the automobile with the 1886 Patent-Motorwagen. Mercedes diesels have long been popular with the German police and taxi services. Mercedes diesel engines are fitted to passenger cars and commercial vehicles. BlueTEC is Mercedes's proprietary exhaust after-treatment system with an SCR catalyst and AdBlue.
The Mercedes community in Europe has a large pool of available Stage files for the standard models. In the Mercedes commercial segment, Stage 1 focuses on torque. The AMG community is active in Germany, but the protection is the toughest in the industry, so Stage 1 on AMG usually requires Bench. High-output Mercedes engines are premium-class with solid headroom for Stage 1. On modern high-output Mercedes, Bench reading is often required because of the encryption. The Mercedes premium segment is a high-output platform with Stage 2 potential.
