Hybrid and electric vehicles (HEVs) are designed to reduce emissions and improve fuel efficiency. They utilize a combination of traditional internal combustion engines and electric propulsion systems, allowing for cleaner energy use and lower environmental impact. Popular models include the Toyota Prius and Tesla Model 3, which showcase the advancements in this technology. These vehicles operate on various power sources, including batteries and regenerative braking systems, which capture energy during braking. As the demand for sustainable transportation grows, HEVs are becoming increasingly popular among consumers looking to reduce their carbon footprint while enjoying the benefits of modern automotive innovation.
