•23hI am reposting my question regarding the government’s plan to introduce new rules for E85 and E100 fuels. What impact will this have on vehicles that are currently E20 compliant? Given the uncertainty around government policy, it’s difficult to predict when these higher ethanol fuel variants might become the only options, potentially affecting millions of consumers. Facing this dilemma, does it still make sense to purchase an ICE car, or should one consider an EV instead? If the government mandates E85 or E100 within the next year or two, what would be the implications for those who own diesel, petrol, or CNG vehicles? Considering my situation, I am deciding between the Amaze and 3XO diesel models, with an annual mileage of 15,000 km and 60% of my travel on highways, what would be the safest choice?

First, on the policy concern. E20 is the current standard, and cars sold today are fully compatible with it. The move to E85 or E100 is still at an early stage and depends on multiple things like flex-fuel engines, fuel availability and nationwide infrastructure. Even if announced, it will take years to become mainstream. It will not suddenly replace E20 across the country in the next one or two years.
For existing vehicles, there is no risk of becoming unusable. Petrol cars will continue to run on available blends, diesel cars are unaffected by ethanol policies, and CNG vehicles are entirely separate from this transition. So there is no scenario where millions of current owners are suddenly stranded.
Now, coming to your dilemma of ICE vs EV. With your usage of around 15,000 km a year and 60% highway driving, an EV is not the ideal fit yet unless you have very reliable charging access on highways. For your pattern, a diesel or efficient petrol still makes more sense in terms of range, flexibility and ease of long-distance travel.
Between your shortlist, the Mahindra XUV 3XO diesel is the better choice. Your usage is high enough to justify diesel, and your highway running will naturally keep the engine and emissions system healthy. It will also give you better efficiency and stronger performance on highways compared to the Amaze petrol. The Amaze is smoother and easier in the city, but it does not match the diesel’s efficiency and torque for your kind of usage.
