India’s automotive industry is navigating one of the most significant transitions in its history. Faced with the twin challenges of reducing emissions and cutting dependence on imported crude oil, manufacturers are being asked to explore multiple solutions simultaneously. While electric vehicles have naturally captured much of the spotlight, they are not the only path forward. The showcase of the Maruti Suzuki Wagon R Flex Fuel serves as a reminder that alternative fuels remain a critical part of India’s long-term mobility strategy.At first glance, the Wagon R Flex Fuel may appear to be a familiar hatchback. Under the skin, however, lies a significant technological advancement. Engineered specifically for ethanol compatibility, the vehicle can operate on ethanol-petrol blends ranging from E20 all the way up to E100, enabling it to run on fuel containing up to 100 per cent ethanol. An advanced engine control unit (ECU) continuously monitors the fuel blend and adjusts engine parameters accordingly, allowing the vehicle to seamlessly adapt to varying ethanol concentrations.
