Mild Hybrid is indeed a type of hybrid technology, but its working principle differs significantly from that of the traditional Full Hybrid. A mild hybrid system typically uses a 48V lithium-ion battery and a belt-driven starter generator (BSG). It recovers braking energy to provide auxiliary power to the engine, but cannot operate in pure electric mode. Its fuel-saving effect is about 10%, with the main optimizations reflected in the smoothness of start-stop and low-speed torque assistance. By contrast, a full hybrid system is equipped with an independent drive motor and can operate in pure electric mode alone (such as the Toyota Prius), achieving a fuel-saving rate of up to 40%, but it has a more complex structure and higher cost. Mild hybrid belongs to the micro hybrid category, and its core value lies in achieving basic energy conservation at a lower cost rather than pursuing electrification performance. For daily commuters, mild hybrid models such as certain Nissan models or the Chery A5 BSG version can deliver improved fuel economy at a relatively affordable price (approximately RM 5,000 to RM 10,000 higher than traditional fuel vehicles). However, if a more advanced electrification experience is desired, full hybrid or plug-in hybrid models should be considered. Currently, both coexist in the market, and the choice depends on balancing budget and environmental protection needs.
