This is a basic concept within alternative energy vehicles to consider when facing automobile interview questions.
How to answer:
Explain that hybrids use both electric and conventional power (usually gasoline), while electric vehicles (EVs) rely solely on electric power. Mention that hybrids have a smaller electric range and use regenerative braking to recharge their batteries, while EVs have a larger battery pack and need to be plugged in to recharge. Highlight the environmental benefits and differences in performance between the two types of vehicles.
Example answer:
"The primary difference between a hybrid and an electric vehicle is their source of power. Hybrid vehicles use a combination of an internal combustion engine (usually gasoline) and an electric motor, while electric vehicles (EVs) rely solely on electric power. Hybrid vehicles typically have a smaller battery pack and a limited electric-only range, and they use regenerative braking to help recharge the battery. Electric vehicles, on the other hand, have a much larger battery pack and need to be plugged into an external power source for recharging. EVs produce zero tailpipe emissions, making them a more environmentally friendly option compared to hybrid vehicles."
