The 2026 Kia Seltos arrives with a bolder, more muscular stance and now measures 4,460mm in length, making it one of the longest in its segment. It features Kia’s new Digital Tiger Face grille, connected LED lighting, and automatic streamline door handles that give it a sharper, more premium identity.
The Tata Sierra, launched earlier with prices starting at Rs 11.49 lakh (ex-showroom) for lower variants, follows a more upright, SUV-focused silhouette. It carries forward its distinctive large glasshouse, rugged stance and signature rear design, staying true to the nameplate’s heritage, while modernising the overall look.
2026 Kia Seltos Vs Tata Sierra Comparison: Powertrain Options
Kia will offer the Seltos with three engine options: a 1.5-litre NA petrol (115 bhp/144 Nm), 1.5-litre turbo-petrol (160 bhp/253 Nm) and a 1.5-litre diesel (116 bhp/250 Nm). Transmission choices include 6MT, 6iMT, IVT, 7DCT and 6AT.
The Tata Sierra is available only with petrol and diesel at launch, with power outputs positioned to meet everyday usability rather than outright performance. Exact figures vary by variant, and the brand is expected to expand the lineup with more configurations over time.

Inside the new Seltos, Kia has introduced a premium cabin layout with a massive 30-inch panoramic display panel housing both infotainment and instrument cluster. The SUV also offers ventilated seats, dual-pane panoramic sunroof, an 8-speaker Bose audio system, 10-way powered driver seat with memory, and a relaxation function.
The Sierra’s interior focuses on practicality and space, featuring a clean dashboard, generous seating room and a range of creature comforts depending on the variant. While not as feature-loaded as the Seltos in its lower trims, higher Sierra variants add premium upholstery, a large infotainment system and connected car features. The Sierra’s feature list is still expanding, with top-spec pricing yet to be announced.

The Tatа Sierra, on the other hand, emphasises upright seating, airy interiors, and a commanding driving view.
