•6hAsking on behalf of a colleague. He plans to buy an EV for regular use, which includes weekly office work (3-4 days), weekend trips with his small family, all within the Bangalore city area. He has booked the Mahindra XEV 9S. Should we wait for the launch of Sierra EV, as it is a bit smaller in size, which may be useful for his city usage? Also, since the Sierra petrol and diesel are still not visible on Bangalore roads as of mid-May 2026, despite having a huge hype during launch, would waiting for the Sierra EV be a wise decision or just a waste of time? Can the increasing petrol price lead to an increase in the cost of EVs? The Bangalore government has already removed the road tax discount on EVs.

The Mahindra XEV 9S is the more sensible choice rather than waiting for the Tata Sierra EV. With no firm launch date for the Sierra EV and uncertain delivery timelines, it makes more sense to opt for the XEV 9S, which is already on sale.
Yes, the XEV 9S is a bit larger than the Tata; however, its light steering, tight turning radius, good visibility and driving aids make it surprisingly easy to drive and live with.
Coming to the second part of your question, Karnataka has introduced new slabs for EV road tax from May 1, 2026, so on-road prices are higher than before, but still running costs remain much lower than petrol. Since your colleague is buying the car now, it will save him from any potential price hikes due to the higher battery import cost or any new taxes.
