Smart City (2002) 0.8 CDI 45 hp — mass-market diesel engine of the passenger segment of the Mercedes-Benz Group AG / Geely (с 2020 — JV) group (Германия, 1926). Stage 1 chip tuning raises power from 45 to 66 hp (+21 hp, +47%) and torque from 110 to 145 Nm (+35 Nm). The 2002 generation — first-generation CDI/TDI/HDi diesels with relatively simple ECU protection; OBD reading works directly.
Smart historically used Mitsubishi and Renault engines. Smart is positioned as an urban premium micro-car brand. Smart specialises in micro urban cars (ForTwo, ForFour). DPF/SCR with AdBlue is standard on all Euro-6 Mercedes diesels. On older Mercedes diesels, Stage 1 is flashed over OBD with no complications. Mercedes diesels are known for smooth, quiet running, a hallmark of the premium segment.
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. On low-output Mercedes engines, Stage 1 is safe and does not over-stress the hardware. On naturally aspirated Mercedes engines without a turbo, the main effect is on throttle response. In the Mercedes city segment, Stage 1 is more about comfort and responsiveness than power.
