Hi, I am planning to buy a car but am confused between the Tata Tiago CNG and the Swift CNG.

Between the two, the Tiago iCNG makes more sense if the priority is keeping running costs low. It uses twin CNG cylinders mounted under the boot floor, so unlike the Swift CNG, it does not sacrifice as much usable boot space. It also has a slightly more powerful CNG engine and, importantly, is the only one of the two available with an AMT on CNG.

The Swift CNG has the advantage in cabin space and overall refinement. It is 50mm longer in wheelbase and 51mm wider, so there is more room inside, and the 1.2-litre engine is smooth enough for everyday use. However, the Swift CNG is manual only and uses a single CNG cylinder, which takes up more of the boot area.

The Tiago is also the more affordable option, with CNG prices starting significantly below the Swift.

I’m planning to buy a new car, and my annual running is around 40,000km, primarily involving highway drives and ghat sections. I have shortlisted the Kia Seltos Diesel HTX and the upcoming facelifted Toyota Innova Hycross ZX. I’m considering two approaches: either buy the Innova Hycross and keep it for the next 10 years, given its reputation for longevity and the expectation that its engine can last at least 4 lakh kilometres, or buy the Seltos, drive it for around 2 lakh kilometres over 4–5 years, sell it and upgrade to a brand-new Seltos or another car of a similar price and size. On paper, the Innova Hycross Hybrid seems like the better choice, considering its long-term reliability and features such as the Ottoman reclining seats. However, I’m concerned that I might get bored of it after four years or that it may start feeling outdated as newer technologies and features enter the market. This makes the second option appealing, as it would allow me to upgrade to a brand-new car every 4–5 years. Which approach would make more sense in the long run, considering my high annual running and ownership costs?

It seems like you're leaning towards the Kia Seltos Diesel HTX, and we think it is a good choice. The diesel engine feels adequately powered for highway usage and ghat driving, and it is likely to return respectable efficiency too. Moreover, despite being modern with all the latest tech and features, the Seltos will be substantially more affordable than the Toyota Innova Hycross hybrid. So unless you need the Innova's extra space, or you frequently travel with six or seven passengers, the Kia Seltos diesel is your best bet.
