New Kia Seltos 2026 vs 2025 Tata Sierra Specifications Compared: Dimensions, Powertrain, And Key Features

Both the new Seltos and the Sierra are modern and boxy, but which one turns out to be better on paper?
The second-generation Kia Seltos, now unveiled, is set to be the latest entrant in the compact SUV space, challenging the buzz created by the new 2025 Tata Sierra. Both the carmakers seem to have gone all out in making their two SUVs look extremely appealing, as well as feature loaded. Now that the rivalry is spiced up, let’s check on paper which of these two SUVs has to offer more:
Price
The Kia Seltos prices are to be announced on January 02, 2026, while its bookings are underway for a token price of Rs 25,000. For more details, check here.
Tata has only announced the starting and mid-spec variant prices of the Sierra while the top-end amounts are yet to be known.
Dimensions
In aspect of size, the new Seltos now stands to be significantly longer, infact the longest compared to all of its competitors.
However, the Sierra is the one which in true sense will give you the feel of a bigger car, thanks to its extra width, height, and wheelbase.
Notably, the Seltos’ bootspace happens to be shallow despite the extra length, while the Sierra has a significantly larger boot that improves its practicality.
Powertrain
CVT - Continuously variable transmission, DCT - dual-clutch automatic transmission, AT - torque converter automatic transmission
The Seltos and Sierra has a pretty similar powertrain setup. Both SUVs feature a naturally aspirated petrol, turbo-petrol and a diesel option with front-wheel drivetrain.
The Seltos’ NA petrol engine returns 7PS more power than that of the Sierra while maintaining almost similar torque output.
The Sierra, on the other hand, generates more power and torque with its diesel engine.
Unlike the Seltos’ turbo-petrol engine with which you get an iMT gearbox, the Sierra’s one can be had with an automatic only.
Features
In the features department, it is the Sierra that stands out to be a little more feature loaded than the new Seltos. Design-wise it gets a few extra quirks, and bigger alloy wheels.
Equipment wise, it features a triple screen display with an extra co-passenger screen, extendable thigh support in front seats, a powered tailgate, and more speakers. Surely, not the deal breaker especially considering the Seltos too is quite well equipped. In fact, it packs some extras over the Sierra like a 10-way power adjustable seat and more interior cabin themes.
CarDekho Says…
While the Seltos has long been the forerunner in sales for Kia, the Sierra brings back a legacy to remember. Both in their own ways are iconic SUVs to set tyremarks on the Indian roads. If you’re a Tata fanboy or relate to the fact that hypes the Sierra, there’s no debate for what to pick. If you’re a normie and are considering both with an equal view point, we’d recommend you wait for us to drive and review the new Seltos once it gets launched. Either way, on paper, both cars has a great spec sheet and you wouldn’t go wrong with both of them.
