1. The advantages of a series-hybrid design include improved fuel efficiency and reduced emissions. The disadvantages include increased complexity and higher cost.<br />2. The Toyota Prius is a mild hybrid, while the Ford Escape hybrid is a full hybrid.<br />3. Mild hybrids have a small electric motor to assist the internal combustion engine, while medium hybrids have a larger electric motor and can run on electric power alone for short distances. Full hybrids can run on electric power alone or use both the electric motor and internal combustion engine.<br />4. A BAS (Battery-Assisted System) costs less than other types of hybrid vehicles because it uses a smaller battery and electric motor, which reduces the overall cost of the system.<br />5. The four modes of operation of a typical hybrid vehicle are: electric mode, hybrid mode, engine drive mode, and regenerative mode.
