Ask experts Latest questions Asked by: Avisham I want to buy a seven-seater, and my annual running is around 20,000 km, mostly on CNG. I am confused between the Kia Carens and the Ertiga. I am concerned about the Carens’ fuel efficiency, especially in city usage. Is the Kia Carens CNG expected anytime soon? There are no plans for a Kia Carens CNG, as the brand offers both a diesel option and an EV for those who want lower running costs. The downside, of course, is that the purchase price of these versions is higher. If you're hell-bent on CNG, the Maruti Suzuki Ertiga is an excellent car, with good space and practicality.However, on most other fronts, the Kia Carens Clavis is better. It has a more upmarket interior with good space in all three rows, and a variety of engine options, including that diesel. Apart from the turbo-petrol engine, which has to be driven carefully to return good fuel economy, the other engines are very fuel-efficient. Hence, if it fits in your budget, we recommend the Kia Carens Clavis. Asked by: Charan I own a 2011 Swift VDI and am looking to purchase a car with good fuel efficiency and, more importantly, better rear-seat comfort for my parents. We do occasional long trips. I initially considered the XEV 9e, but I am concerned about charging infrastructure and waiting times during long or unplanned trips. I then looked at the Grand Vitara, but the rear seat was not comfortable for my parents and felt similar to the Swift. Should I go for the Sierra diesel or wait for strong hybrid options? Yes, you're right. Although the situation has improved lately, the concern of range and finding a charger on a long trip looms large over EV ownership. Therefore, if you do such trips, it's best to avoid an electric car for now.The only new strong hybrid model on the immediate horizon is the Kia Seltos hybrid, but this version is unlikely to be available before the end of 2026 or early 2027. You should check out the Tata Sierra diesel, as it currently has possibly the best rear seat space and comfort in the segment. The diesel engine is familiar, and while it isn't very refined, it has the requisite pulling power you need on your long highway trips. Fuel efficiency should also be good, and there is the convenience of a smooth automatic gearbox with this diesel engine as well. View all questions Can’t decide which car to buy?
