Tata has launched the Aeris at a starting price of Rs 5.29 lakh, going up to Rs 9.19 lakh. This sedan is based on the Tigor and replaces it. Tata has designated the Aeris as a private sedan, meaning it will not be sold for commercial use. Its direct competitors include the Maruti Suzuki Dzire, Hyundai Aura and Honda Amaze. In this comparison of the Tata Aeris iCNG and the Hyundai Aura CNG, we determine which sedan offers better value in 2026.
Price and Variants
Model | Variant | CNG MT | CNG AMT |
|---|---|---|---|
Tata Aeris iCNG | Smart | Rs 6.29 lakh | – |
Tata Aeris iCNG | Pure | Rs 7.14 lakh | Rs 7.69 lakh |
Tata Aeris iCNG | Pure Plus | Rs 7.74 lakh | Rs 8.29 lakh |
Tata Aeris iCNG | Creative | Rs 8.49 lakh | Rs 9.04 lakh |
Tata Aeris iCNG | Accomplished | Rs 9.19 lakh | Rs 9.74 lakh |
Hyundai Aura CNG | S | Rs 7.82 lakh | – |
Hyundai Aura CNG | Corporate | Rs 7.91 lakh | – |
Hyundai Aura CNG | SX | Rs 8.60 lakh | – |
Tata offers CNG with an AMT for those who want a hassle-free drive, while the Aura CNG is available only with a manual gearbox. At the entry level, the Aeris undercuts the Aura by Rs 1.53 lakh. The Aeris has five CNG variants, giving buyers more choice, whereas the Aura CNG has three. At the top end, the Aeris Accomplished CNG MT (Rs 9.19 lakh) is Rs 59,000 more expensive than the Aura SX CNG, though it also comes with a longer features list.
Engine and Performance
Spec | Tata Aeris iCNG | Hyundai Aura CNG |
|---|---|---|
Engine | 1.2L Revotron, 3-cyl | 1.2L Kappa, 4-cyl |
Displacement | 1,199cc | 1,197cc |
Power (CNG mode) | 75.5 PS | 69 PS |
Torque (CNG mode) | 96.5 Nm | 95 Nm |
Transmission | 5-speed MT or 5-speed AMT | 5-speed MT only |
CNG tank capacity | 70 litres | 65 litres |
The Aeris has the edge in both power and torque, though the torque gap is marginal. The Aura's 4-cylinder engine is known for its smooth running. The Aeris, on the other hand, is new to the market and offers an AMT gearbox, which the Aura CNG does not. Claimed mileage figures for the Aura vary between sources (22 to 28 km/kg), and the Aeris figures are yet to be tested.
Dimensions
Dimension | Tata Aeris iCNG | Hyundai Aura CNG |
|---|---|---|
Length | 3,995 mm | 3,995 mm |
Width | 1,684 mm | 1,680 mm |
Height | 1,532 mm | 1,520 mm |
Wheelbase | 2,450 mm | 2,450 mm |
Ground clearance | 170 mm | 165 mm |
Boot space (petrol) | 419 litres | 402 litres |
Boot space (CNG) | 227 litres | Not confirmed* |
Both sedans follow the sub-4-metre rule and share the same length and wheelbase, which suggests similar legroom. The Aeris is slightly wider and taller than the Aura and has 5 mm more ground clearance.
Interior and Boot
Both sedans have a neat, practical cabin. The Aura's dashboard has a honeycomb-pattern design, while the Aeris feels more open inside, with a minimalist dashboard.
Tata has taken a different approach with the Aeris, placing twin CNG cylinders beneath the boot floor. This technology is tried and tested, as the same setup is used in the Altroz, Tiago and Nexon. It also lets owners make fuller use of the boot.
The Aura uses a single-cylinder setup mounted inside the boot. Owners report reasonable luggage space, but the quoted 402-litre boot figure is for the standard car, and a single cylinder will eat into it. On practicality, the Aura loses to the Aeris.
Features
Feature | Tata Aeris iCNG | Hyundai Aura CNG |
|---|---|---|
Touchscreen | 26.03 cm (10.25-inch) HD, wireless Android Auto/Apple CarPlay | 8-inch, Android Auto/Apple CarPlay |
Instrument cluster | 12.7 cm digital | Analogue-cum-digital |
Cameras | 360° HD camera with 2D/3D views (Creative and above) | Rear parking camera only (no 360° view) |
Blind View Monitor | Higher trims | Not offered |
Ventilated front seats | AeroLux ventilated seats (higher trims) | Not offered |
Rear AC vents | Yes | SX trim only |
Cooled glove box | Yes | Not offered |
Automatic climate control | Yes | SX trim only |
Tyre Pressure Monitoring System | Yes | Higher trims* |
Wireless charger | Yes | Not offered on CNG trims |
Airbags | Six, standard across the range | Six on higher trims; lower trims may differ* |
CNG starting | Direct CNG start (starts straight in CNG mode) | Starts on petrol, then switches to CNG |
Leak protection | Automatic leak detection; switches to petrol on leak | Standard CNG safety protocols (not separately highlighted) |
Fire extinguisher | Under co-driver's seat | Not specified |
Thermal incident protection | Cuts CNG supply and vents gas safely | Not specified as a distinct named feature |
Tata has played its cards well on features, making the Aeris more loaded across a wide range of trims. Hyundai offers a solid, well-equipped SX but only three CNG trims, so buyers on a tighter budget will find more choice with the Aeris.
End Note
The Aeris iCNG comes out ahead on almost every count that matters to a CNG buyer. It has a lower entry price, five variants instead of three, an AMT option, more power, twin-cylinder technology that preserves boot space, and a longer features list, including direct CNG start and dedicated thermal safety systems.
The Aura claws back some ground at the top, where the SX CNG is Rs 59,000 cheaper than the Aeris Accomplished MT. Hyundai's strong sales record, smooth 4-cylinder engine and wide service network also carry real weight for buyers who prioritise reliability and resale value.
For most buyers shopping on a budget or wanting the most practical CNG sedan for daily use, the Aeris iCNG makes the stronger case. For those who prefer a proven name and are happy with a manual-only, less feature-rich car, the Aura CNG remains a dependable choice.
