The term designates a mild-hybrid system that enhances vehicle performance and efficiency. This technology typically involves replacing the conventional alternator with a motor generator unit, which provides electric assist to the engine, particularly during acceleration and start-up. An example of its application is seen in certain pickup trucks, where it supplements the internal combustion engine, offering improved responsiveness and fuel economy.
This type of system offers several advantages. It can reduce fuel consumption by allowing the engine to operate more efficiently, particularly during stop-and-go traffic. It also delivers smoother acceleration, providing extra torque when needed. Furthermore, it can enable features like regenerative braking, which recovers energy during deceleration to recharge the battery, increasing overall efficiency. Early implementations sought to bridge the gap between traditional internal combustion engines and more advanced hybrid powertrains.
