Maruti Suzuki Baleno CNG AMT Launch: Swift, Dzire Also Get Automatic CNG – Prices, Mileage and Boot Space Trade-Off

Maruti Suzuki launched AMT versions of the Swift, Dzire and Baleno CNG on 18 September 2026, becoming the second carmaker in India after Tata Motors to pair a factory-fitted CNG kit with an automatic gearbox. The Maruti Suzuki Baleno CNG AMT launch starts at Rs 8.32 lakh (ex-showroom), while the Swift CNG AMT begins at Rs 7.92 lakh and the Dzire CNG AMT at Rs 8.53 lakh, according to Autocar India and The Times of India.

Swift, Dzire, Baleno CNG AMT: prices and claimed mileage

All three cars use the same Z12E 1.2-litre, 3-cylinder engine, producing about 69–70hp and roughly 102Nm in CNG mode, mated to a 5-speed AMT. Notably, the AMT versions claim slightly better efficiency than their manual CNG counterparts — unusual, since automatics typically trail manuals on mileage.

The Dzire claims the highest figure at 36.47 km/kg — 2.74 km/kg more than its manual version — while the Swift's AMT claims 2.49 km/kg more than the Swift CNG manual. These are ARAI-certified figures, so real-world mileage will typically be lower.

What the AMT premium costs you

Compared to the corresponding CNG manual versions, the AMT-equipped Swift and Dzire CNG variants cost Rs 35,000 extra. That premium buys clutch-free city driving while retaining CNG's low running costs — a combination Maruti had not offered before. The Baleno, sold through the Nexa network, is now available with four powertrain choices: petrol manual, petrol AMT, CNG manual and CNG AMT, per CarWale.

The boot-space trade-off vs Tata's dual-cylinder cars

All three Marutis retain a single 55-litre (water-equivalent) CNG tank mounted in the boot, with the spare wheel alongside it — leaving limited luggage space. This is a key difference from rivals: the Swift and Dzire CNG AMTs compete with the Tata Tiago and Tigor CNG AMTs, which use a dual-cylinder setup that frees up more boot room. Maruti's own Victoris, by contrast, uses an underbody CNG tank. If you regularly carry full luggage, this is worth checking in person before booking.

Should you buy one?

The CNG AMT combo makes most sense for high-mileage city drivers who want automatic convenience without giving up CNG fuel savings — the Rs 35,000 premium over the manual can be recovered relatively quickly at typical urban running. Buyers should note that these are introductory ex-showroom prices announced on 18 September 2026; on-road prices vary by state and may have been revised since launch, so confirm current variant-wise pricing on Maruti's Arena and Nexa websites. Search interest in the Swift Dzire Baleno CNG AMT cluster spiked around the launch, per Google Trends data observed on 18 September 2026 — but that reflects curiosity, not confirmed sales or bookings.
