Indian carmakers are using lightweight materials like high strength steels and aluminium alloys to reduce the weight of bulky SUVs while adding more features. This helps to maintain lower CO2 emissions and improve fuel efficiency. The usage of high-strength steels and hot-stamped parts has increased in new age cars, reducing weight by around 30 kg. Mahindra & Mahindra has managed to reduce the weight of their SUVs, such as the XUV-700, by 79 kg despite new feature additions and increased vehicle length. Additionally, the sales of plug-in hybrids, electric vehicles, CNG, and ethanol options are offsetting emissions from larger vehicles and contributing to a reduction in average CO2 emissions in India.
