Read Original ArticleKey Points
Delhi's upcoming Electric Vehicle (HEV) policy plans to extend road tax and registration fee exemptions to hybrid electric vehicles (HEVs). This initiative is significant for UPSC aspirants, especially for GS Paper 3, focusing on environment and technology. Last Updated: 10-03-2026
Key Facts About Hybrid Electric Vehicles (HEVs)
- A Hybrid Electric Vehicle (HEV) combines a conventional internal combustion engine (ICE) with an electric propulsion system.
- HEVs aim to achieve better fuel efficiency and lower emissions.
- They operate without the need for external charging, using self-charging capabilities.
- HEVs use regenerative braking to convert kinetic energy into electricity.
- Types include Parallel Hybrid, Series-Parallel Hybrid, and Plug-in Hybrid Electric Vehicle (PHEV).
- Advantages include excellent fuel economy and lower emissions, while disadvantages include higher initial costs.
India's Push for Sustainable Transportation
The promotion of Hybrid Electric Vehicles aligns with India's strategic goals of reducing carbon emissions and enhancing energy security. By fostering the adoption of HEVs, India aims to decrease its reliance on fossil fuels and improve urban air quality. The country's commitment to sustainable transportation is evident in its policies and international agreements to combat climate change.
UPSC Relevance
- GS Paper 3: Environment, Technology, and Sustainable Development.
- Prelims Angle: Questions may focus on definitions, types of hybrids, and their advantages.

Frequently Asked Questions (FAQs)
- What is a Hybrid Electric Vehicle (HEV)? An HEV combines an internal combustion engine (ICE) with an electric motor and battery to improve fuel efficiency and reduce emissions, typically without requiring external charging.
- How does regenerative braking work in hybrid vehicles? During braking, the electric motor acts as a generator, converting kinetic energy into electricity and storing it in the battery.
- How are Battery Electric Vehicles (BEVs) different from hybrids? BEVs run entirely on electric batteries with zero tailpipe emissions, while hybrids combine electric propulsion with an internal combustion engine.
