Fill the gap between petrol and electric
Q&A with Girish Wardadkar, the president and executive director of KPIT Cummins What are the main advantages of Revolo? Its biggest selling point is its fuel efficiency of up to 60 per cent. Hybrid models so far offer fuel efficiency of only 20 to 25 per cent. And the second selling point is its low cost. Revolo is 80 per cent cheaper than other plug-in hybrid conversion kits in the US. How did you manage to keep your costs so low?
We optimally designed and patented our own motor instead of getting an off-the-shelf motor. We were careful not to over-design our product, using only components that are absolutely essential. Instead of using lithium-ion batteries, which need to be imported and cost five times more, we used lead acid which are cheaper and available domestically. During our research and development, we carefully studied the firing pattern of IC [internal combustion] engines and identified the weak spots that lead to fuel wastage.
Is there a market for hybrid cars in India? Electric cars are the future, but they are way too expensive, while internal combustion engines are not going anywhere. Until we can make electric cars more cost-efficient, hybrid technology, which is a mix between electric and IC, is the future. If we increase the efficiency of hybrid cars - increase fuel efficiency, cut carbon emissions, while keeping costs low - this technology will find takers.
