India’s automotive ecosystem is rapidly evolving, and one of the biggest shifts is the growing emphasis on EV Lightweight Components. As electric vehicles become more mainstream, manufacturers are racing to improve efficiency and cut “range anxiety”—a major concern among buyers worried about running out of charge before reaching a station. This push has opened a new growth frontier for India’s auto parts makers, who are increasingly prioritizing lightweighting strategies to enhance overall vehicle performance.
At least two large auto component makers—Pune-based Belrise Industries Ltd and Gurugram-based ASK Automotive Ltd—are focusing on making lighter parts, as automakers look to balance the extra weight of lithium-ion batteries in EVs compared to traditional internal combustion engines (ICE)
Why Lightweighting Matters in EVs?
Reducing vehicle weight has become a strategic priority. Analysts highlight that a 10% drop in weight can boost power efficiency by 6–8%, directly improving driving range. EVs naturally weigh 20–30% more than traditional internal combustion engine (ICE) vehicles because of their heavy lithium-ion battery packs, which can add up to 350 kg. By integrating EV Lightweight Components, manufacturers can offset this additional load and enhance the EV’s real-world usability.
In addition to increased range, lighter vehicles offer faster acceleration, improved handling, shorter braking distances, and reduced tyre wear—delivering a more refined driving experience overall.
Materials Shaping the Future of Lightweight EV Parts
Auto component makers such as Belrise Industries Ltd and ASK Automotive Ltd are actively investing in production lines dedicated to lighter parts. This shift involves transitioning from traditional steel and cast iron to advanced materials such as:
- Aluminum and Magnesium: Ideal for chassis parts, battery housings, and structural components. Aluminum is one-third the weight of steel, while magnesium is even lighter.
- Carbon-Fibre Composites: Five times stronger than steel yet far lighter, widely used in premium EVs for panels, wheels, and reinforcement structures.
- Advanced Polymers and Plastics: High-performance thermoplastics replace metal in trims, brackets, and certain engine-related parts.
- Lightweight Electronics: Innovations like Panasonic’s compact two-inch speakers deliver high output while reducing door weight.
These material innovations reinforce the growing role of EV Lightweight Components across every layer of vehicle design.
Impact on Range and Efficiency
Industry data suggests that lightweighting can enhance EV driving range by 6–13.7%. A lighter vehicle demands less energy, enabling potential battery downsizing without compromising performance. This is especially important as automakers balance efficiency with affordability.
Government Push and Market Growth
India’s Production Linked Incentive (PLI) scheme, supported by a ₹25,938-crore outlay, is accelerating domestic production of advanced EV parts. The auto component industry is expected to reach $200 billion by 2030, with up to 30% of new investments flowing toward EV technologies—including EV Lightweight Components.
