Global and local automakers in India are gearing up for an anticipated shift to electric vehicles with massive investments over the next few years, as the country with the world's fourth-largest car market aims to replace all conventional vehicles with EVs by 2030.

Japan's Suzuki Motor Corp. and South Korea's Hyundai Motor Co. unveiled EV models set for launch in the country at the biennial Auto Expo, being held on the outskirts of New Delhi through Wednesday, while major local manufacturers are boasting big spending on their own eco-friendly EV technology.

Maruti Suzuki India Ltd., the country's largest maker of passenger cars, showcased e-SURVIVOR, its EV concept model, at the auto show and said it will launch its first EV in India in 2020.
