Smart ForTwo (2000) 0.8 CDI 54 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 54 to 75 hp (+21 hp, +39%) and torque from 130 to 165 Nm (+35 Nm). Diesel engines built in 2000 — the era of classic Common Rail without strong encryption.

The Smart #1 and #3 are the new generation of electric crossovers built on the Geely platform. Smart is a German compact-car brand within the Mercedes-Benz Group, and since 2020 a joint venture with Geely. Smart historically used Mitsubishi and Renault engines. Mercedes diesels have long been known for legendary reliability, with German taxi fleets running to million-kilometre mileages. Mercedes pioneered CDI (Common-rail Direct Injection) technology on passenger-car diesels, in series production since 1997. Mercedes diesels have long been popular with the German police and taxi services.

Stage 1 on Mercedes often requires refreshing the adaptations after the flash. 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. 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. On low-output Mercedes engines, Stage 1 is safe and does not over-stress the hardware.
