R Series Diesel Engine

SDEC's SC 25E/28R series engine is a newly introduced and developed small-displacement diesel engine after SDEC joined SAIC, and it can fully meet the National IV and the National V Emission Standard. This engine is introduced from the Italian VM Company, embodying advanced technology and sophisticated craft, and it is mounted in many of the worldwide best-selling vehicle models including Alfa Romeo, Chrysler Voyager, Land Rover Defender, JEEP Cherokee, and LDV. During the process of introduction and production, SDEC inherited its sophisticated manufacturing process and outstanding performance, ensuring the product quality. With the development of the domestic auto market, this engine will be a preferred power for many domestic diesel vehicles.
