How do HYBRID and E-POWER car systems differ?

The difference between conventional HYBRID car systems (such as Toyota Hybrid or Honda e:HEV) and the E-POWER system (found in the Nissan Kicks) lies in the primary role of the internal combustion engine (gasoline) in powering the wheels.

Hybrid (Series-Parallel Hybrid):
1. This is a car that uses energy from gasoline and electricity to power the wheels simultaneously or separately.
2. It can be likened to the operation of "the engine assisting the motor" or "the motor assisting the engine."
3. It features a complex power delivery system to achieve maximum efficiency.
 
E-POWER (Series Hybrid/Range Extender):
1. This is a car that is powered 100% by the electric motor at all times.
2. The gasoline engine's sole function is to generate electricity to charge the battery and supply power to the motor.
3. The driver therefore gets the driving experience of an Electric Vehicle (EV) but can still refuel with gasoline normally.
