In a major push toward accelerating India’s EV transition, Bengaluru-based Exponent Energy has launched ‘Exponent Oto’, an innovative retrofit technology that converts existing CNG and LPG three-wheelers into fully electric vehicles capable of charging from 0–100% in just 15 minutes.
The new retrofit solution, initially available for passenger three-wheelers, integrates seamlessly with Exponent’s proprietary energy ecosystem through its e^pump fast-charging network. The entire conversion process takes just 24 hours, offering drivers a fast, affordable, and practical route to clean mobility.
Once retrofitted, vehicles deliver class-leading performance, accelerating from 0–30 km/h in under 4.5 seconds and offering a real-world range of 140–150 km. The electric autos also feature IP67-rated water resistance, hill-start assist, and IoT-enabled GPS and diagnostics for real-time performance monitoring.
Each Exponent Oto conversion comes with a 5-year warranty or 3,000 charging cycles, providing reliability and long-term peace of mind for drivers. With zero downpayment, flexible EMIs, and an assured buyback after three years, Exponent estimates that auto drivers can save up to ₹5,000 per month, as combined charging and EMI costs remain lower than current fuel and maintenance expenses.
Arun Vinayak, CEO and Co-founder of Exponent Energy, said, “We want every driver to experience Exponent’s rapid-charging EV technology as fast as possible. Retrofitting is the best way to make great tech accessible and affordable, helping India achieve sustainability at scale.”
Echoing this sentiment, Ayush Bhargava, Head of Business, Exponent Energy, added, “Exponent Oto allows drivers to shift from LPG or CNG to EV at nearly half the cost, making it easier and faster to meet India’s 2030 EV penetration targets.”
Beyond improving driver economics, the Exponent Oto initiative is set to play a key role in reducing carbon emissions, improving urban air quality, and strengthening India’s energy security — marking another milestone in the country’s transition to sustainable, technology-driven mobility.
