Maruti Suzuki has just widened its CNG lineup by adding an AMT option to the Swift, Dzire, and Baleno S-CNG range. These are the first CNG cars in Maruti’s portfolio to get AMT transmission. This move finally gives Swift buyers a CNG car they don't have to shift gears in. This puts the Swift S-CNG AMT in direct competition with the Tata Tiago CNG AMT, which has offered this convenience for a while and was recently updated with the facelifted 2026 Tiago, adding paddle shifters to the mix. Let’s deep dive and decode this Maruti Swift S-CNG AMT vs Tata Tiago CNG AMT comparison.
Price and Variants
Model | Variant Range | Price (ex-showroom) |
|---|---|---|
Maruti Swift S-CNG AMT | VXI, VXI (O), ZXI | Rs 7.92 lakh onwards |
Tata Tiago CNG AMT | Pure, Pure+, Pure+ A, Creative | Rs 7.12 lakh onwards |
On paper, the Tiago CNG AMT actually undercuts the Swift by a fair margin at the entry point. Both cars are spread across three to four trims, giving buyers more choice on where to enter the lineup. The Swift, meanwhile, counters with the reputation of Maruti's dealer and service network, which counts for a lot with CNG buyers who want easy, nationwide access to servicing. Tata, on the other hand, already has an established product image of making the safest cars.
Engine and Performance
Spec | Swift S-CNG AMT | Tiago CNG AMT |
|---|---|---|
Engine | 1.2-litre, 3-cyl Z12E petrol | 1.2-litre, 3-cyl petrol |
Power | 69.75 PS | 75.5 PS |
Torque | 101.8 Nm | 96.5 Nm |
Transmission | AMT | AMT |
Fuel tanks | 55-litre water-capacity CNG cylinder | 60-litre water-capacity CNG cylinder |
The Tiago has a slight edge in outright power. Whereas, Swift has comes with marginally higher torque, which tends to matter more in stop-start city traffic, exactly where an AMT-CNG combo is meant to shine. The Tiago's facelift also throws in paddle shifters on the AMT, letting you manually hold gears when needed, something the Swift doesn't offer.
Features
The Maruti Suzuki Swift S-CNG AMT carries the same Maruti's familiar and fuss-free cabin, with connected-car tech, a touchscreen with wireless Android Auto/Apple CarPlay. It also comes with usual safety kit including dual airbags as standard and more available further up the range.
The Tiago iCNG AMT is ahead in terms of features. It makes the way with a 360-degree camera, dual wireless charging pads, a digital instrument cluster with Bluetooth, and Tata's IRA connected-car suite with dozens of connected features. For a segment that used to be about the bare essentials, the Tiago is pushing the equipment list noticeably further. Tata is also ahead with a feature of direct CNG start compared to Maruti.
Practicality
Both cars use CNG tanks that eat into boot space versus their petrol-only versions, which remains the universal trade-off with factory-fitted CNG kits in this class. Tata Tiago offers twin-cylinder tech, which preserves a good amount of boot space for the users. At this price point, expect a noticeably smaller boot than you'd get on the petrol variant.
End Note
If low running costs and Maruti's wide service reach matter most to you, the Swift S-CNG AMT is the easier, no-fuss pick. It's mechanically simple, well-proven, and backed by a dealer network that's hard to beat for CNG upkeep. If you want more kit for your money, better boot practicality thanks to the twin-cylinder setup, and don't mind stepping outside the Maruti ecosystem, the Tiago CNG AMT makes a stronger case, undercutting the Swift on price while offering noticeably more features and a safer product image at the top end. It really comes down to whether you value Maruti's brand reassurance or Tata's better-equipped, more practical package.
