Why does getting a diesel automatic SUV always have to cost so much? You want the torque of a diesel for those long highway runs, and the ease of an automatic gearbox for bumper-to-bumper city traffic. But every time you start hunting, the price tags seem to be written for someone with a very different salary slip than yours. For years, if you wanted all three diesel, automatic, SUVs, you had to be ready to shell out significantly over Rs 13 lakh, at minimum. It felt like a luxury reserved for a specific kind of buyer. Until one car quietly broke that rule. Let’s see which car it is.

Cheapest Diesel Automatic In India
The Kia Sonet HTE(O) Diesel AT is priced at just Rs 9.80 lakh (ex-showroom), which means you can now own a diesel automatic SUV from a premium Korean brand for under Rs 10 lakh. That’s not a misprint. That’s a genuine shift in what the Indian car market is willing to offer buyers on a budget. Kia introduced this variant in March 2026, making the diesel-AT available from the one-above-base HTE(O) trim.

What’s Under the Hood?
The Sonet HTE(O) Diesel AT is powered by a 1,493 cc diesel engine that produces 114 bhp at 4,000rpm and 250 Nm of torque between 1,500 and 2,750rpm, paired with a 6-speed automatic transmission. 250 Nm of torque arriving very early in the rev range means the car feels punchy and effortless in city traffic. Thanks to the body-to-weight ratio, and then there’s the mileage. The Sonet returns a certified mileage of 24.1 kmpl, a figure that genuinely surprises people when they first hear it.

What Do You Get? – Cheapest Diesel Automatic In India
So, HTE(O) is a base-adjacent variant, so you need to understand what’s included and what isn’t. The variant comes with a multi-function steering wheel, sunroof, rear sunblind, power-adjustable exterior mirrors, ABS, front power windows, and dual-tone wheel covers. You also get the essentials, like central locking and USB Type-C charging ports, along with dual airbags, electronic stability program, hill-hold assist, and rear parking sensors.
What you don’t get is the premium extras: no touchscreen infotainment, no alloy wheels, features like a 10.25-inch touchscreen, 360-degree camera.

The Design
The Sonet’s dimensions also work in its favour for Indian conditions. At 3,995mm in length, 1,790mm in width, and 1,642mm in height, with a 2,500mm wheelbase, it sits comfortably in the sub-4-metre bracket, which also means lower road tax and insurance costs for buyers. Practical option for someone who occasionally hits the highways and is a daily city commuter.
The HTE(O) Diesel AT is available in 9 colour options, including Glacier White Pearl, Sparkling Silver, Pewter Olive, Intense Red, Aurora Black Pearl, Imperial Blue, Gravity Grey, and dual-tone combinations, plenty of personality to pick from.

What Edge Does It Get Over Rivals? – Cheapest Diesel Automatic In India
At Rs 11.68 lakh (on-road, Mumbai), the closest diesel automatic competitors are the Hyundai Venue HX 5 Diesel AT at Rs 14.27 lakh (on-road, Mumbai) and the Tata Nexon Pure Plus Diesel AMT at Rs 12.90 lakh (on-road, Mumbai). The Sonet undercuts both by a meaningful margin, which is what makes this variant genuinely interesting for budget-conscious buyers.
