Tata kick-started India’s compact sedan segment with the Indigo CS, followed by the Tigor, and now the baton passes to the Aeris. Essentially a heavily reworked Tigor, the Aeris brings fresh styling, a more upmarket cabin and a longer list of features. That alone makes it an interesting proposition, but its timing could be its biggest advantage. Tata has a CNG option in a market where demand for the fuel is growing rapidly, with CNG cars accounting for nearly 22 percent of passenger vehicle sales in FY2026, up from around 12-13 percent three years ago in FY2023. That gives the manufacturer an interesting opportunity.
Tata Aeris iCNG exterior design and engineering -
Looks more modern and upmarket than the Tigor
The Tata Aeris looks more modern and sleeker than the Tigor and borrows several elements from the Tiago, giving the two cars a similar visual identity.
At the front, it gets slim LED headlights with integrated LED daytime running lamps (DRLs), joined by a gloss-black trim and a new bumper with wider air inlets. The fog lamps get an upgrade, with LED units instead of the Tigor’s halogen ones. The Aeris also gets a new clamshell bonnet.
In profile, the iCNG gets the 14-inch stylised steel wheels which look undersized, particularly against the prominent wheel-arch cladding. The cladding is made from recycled materials and features a speckled texture. The use of chrome on the door handles and the window line further gives some contrast to the Aeris’ otherwise clean profile.
The Aeris retains the Tigor’s distinct coupe-like roof that flows into the tail. The rear features segmented LED taillights joined by red plastic trim, and new Aeris lettering on the centre of the tailgate. The rear bumper features a reverse light and has an overall clean design.
The Aeris is 3,995mm long, 1,684mm wide and stands 1,532mm tall. It has a wheelbase of 2,450mm. While Tata has not quoted an official ground clearance figure, we found it adequate for broken roads and large speed breakers. All of this is expected to appeal to most buyers.
Tata Aeris iCNG interior space and comfort -
Lighter theme makes the cabin feel airy, and revised cushioning improves seat comfort
The Tata Aeris’ interior layout is the same as the Tiago and looks neat. The lighter beige theme makes the cabin feel airy. However, this same thing might make it difficult to keep the interior spick and span. The dashboard has a clean look, featuring two free-standing displays and a revised 2-spoke steering wheel.
The manual variants feature a new, more premium-looking gear stalk, while the AMT variants get a cleaner-looking rotary drive selector with N (neutral), D (drive) and R (reverse) modes. The rotary dial does not feel finicky, and the modes switch seamlessly. The change in drive modes (N, D and R) is reflected on the instrument cluster, which worls seamlessly.
The centre console has also been thoroughly redesigned for a cleaner look and a more practical application. It features two rubberised pads to keep phones, one of which gets wireless charging capability in the top-spec Accomplished trim. The centre console also features two cupholders and a leatherette-wrapped centre armrest which integrates a decent cubby space. The doors have floating-style handles integrated with the armrest, which feel sturdy.
The seats feature revised cushions and bolsters that have increased the overall comfort and are wrapped in a part leatherette upholstery that looks and feels premium. The rear seats are comfortable as well and offer good legroom and kneeroom. The headroom, however, could be an issue for passengers over 6 feet tall. The rear passengers benefit from dedicated air vents, a centre armrest with two cupholders and a 65-watt Type-C charger. These seats get fixed headrests.
Aeris CNG's boot space figure is not revealed, but could be similar to the Tigor CNG's 227-litre space.
The Aeris iCNG gets a dual-cylinder tank setup inside the boot, unlike its rivals that use a single CNG tank and are left with very little usable boot space. The clever layout means the Aeris has enough room for a couple of backpacks and a small luggage bag. Tata also offers a 13-inch underbody-mounted spare wheel, which is more useful than a puncture repair kit.
Tata Aeris iCNG features and safety -
Gets a lot of modern-day features, some of which are segment-first
Like other Tata cars, the Aeris is filled with features to the brim. Along with a part-leatherette seat upholstery, it debuts a front seat ventilation function for the compact sedan segment, which is offered with the Aeris’ top Accomplished trim. During our drive, the seat ventilation was very effective in cooling the cabin in Faridabad’s near 40deg ambient temperature. However, there’s no confirmation on the infotainment system or the driver’s display when the feature is engaged or the ventilation level is changed.
A 10.25-inch infotainment touchscreen is the same as before, which remains slick to use and has no lag even when browsing through multiple menus. The user interface (UI) is also easy to get used to. The Aeris continues with the Tigor's 360-degree camera setup that is also lag-free and works decently well even in low-light conditions. The surround-view feed is not of the highest quality, but is good enough compared to rivals. Tata has added a new DVR feature, which allows the surround-view cameras to double up as a dashcam and record the surroundings of the car. These recordings can be stored and accessed either on the infotainment touchscreen or a USB drive, and can also be seen on a phone via a QR code.
The instrument cluster has analogue dials that show fuel levels and the rev counter, and digital displays for the speed and other general information. The steering wheel’s tilt angle and the driver’s seating position sometimes obscure certain details. The steering wheel lacks the leatherette wrap offered with the Tigor, but feels nice to hold nevertheless. The wheel is now free of the Tigor’s scratch-prone gloss black trim and thankfully retains physical controls. It also gets cruise control, but only with the manual variants.
The 4-speaker, 2-tweeter audio system is a step down from the Tigor’s 4-speaker, 4-tweeter setup, although sound quality is still good enough for the price. Certain features also could have been integrated better. The wireless charging pad can also heat phones, particularly during extended use. Cooling vents near the pad could have fixed the issue. The infotainment system switches to the blind-spot monitor every time the indicators are used, which is a welcome feature. However, it sometimes replaces the navigation, which can be annoying, but an option is offered to switch the view off. The rear seats also lack pressure sensors, so the seatbelt warning continues to chime until the belts are fastened.
Standard safety features include 6 airbags, ISOFIX child seat anchorages on the rear seats, rear parking sensors and 3-point seatbelts with reminders on all seats. Higher variants equip the Aeris with a 360-degree camera, a day/night inside rearview mirror (IRVM), rain-sensing wipers, rear defogger, a tyre pressure monitoring system (TPMS) and ESP with traction control. The pre-facelift Tigor received a four-star rating from Global NCAP in 2020, but the Aeris has yet to be tested by Bharat NCAP.
Tata Aeris iCNG performance and refinement -
Performance in the city is adequate, but it feels out of breath if pushed hard
The Tata Aeris continues with the Tigor’s 1.2-litre, three-cylinder naturally aspirated engine, producing 76hp and 97Nm in CNG guise. It is offered with a five-speed manual and a five-speed AMT, and we drove the latter.
At city speeds, the engine has enough performance to keep up with traffic, but the CNG-AMT combination is not particularly responsive. There is a pause between pressing the accelerator and the powertrain responding when you need to accelerate quickly.
The AMT has a creep function which works slawlessly and will be helpful in bumper-to-bumper traffic. However, push the accelerator a bit and it picks up speed with a jerk, which can get tiresome in stop-and-go traffic. Once up to speed, however, the Aeris settles into a relaxed rhythm and is comfortable enough when driven at a steady pace. The AMT also gets paddle shifters for manual gear changes, which are useful when you want more control over the gearbox, particularly during overtakes.
On the highway, the lack of response is more noticeable, particularly when overtaking. The Aeris can maintain triple-digit speeds, but building speed takes time, and overtaking requires some planning. The rotary gear selector itself, however, as mentioned above, is neat and easy to use.
Refinement is a weak point. The engine feels generally smooth when driven gently, but above 2,500rpm, the engine sounds coarse and vibrations become quite pronounced. Wind and road noise insulation isn’t particularly strong either, so the cabin gets fairly noisy at higher speeds.
Tata Aeris iCNG ride comfort and handling -
Has a commendable ride quality for a sedan on both rough roads and highways
Despite being a sedan, it does not feel particularly vulnerable to bad roads. The suspension does a good job of absorbing broken surfaces and larger bumps without unsettling the car, while the ground clearance is adequate for tackling rough roads and large speed breakers. Another aspect that helps the Aeris are the 14-inch wheels, which are a size lower than the ones offered with the petrol variants. The higher sidewalls definitely makes the ride feel plushier than the petrol.
Out on the highway, the Aeris is equally composed. It stays planted at triple-digit speeds and does not feel floaty or nervous when driven quickly. The steering is also nice to hold and offers decent feedback, although there is some vagueness around the centre that takes away a little from the confidence.
Tata Aeris iCNG mileage and efficiency
We expect it to offer a real-world mileage in the 25-30km/kg range
While we haven’t put the Aeris iCNG through our full test yet, its CNG powertrain should make it considerably more economical to run than the petrol version. Tata is yet to reveal an official efficiency figure, but we expect real-world mileage to be in the 25-30km/kg range. We’ll bring you our tested mileage figures once we put the Aeris iCNG through our standardised test procedures.
Tata Aeris iCNG value for money -
CNG buyers don’t have to compromise on features
The Aeris iCNG, priced from Rs 6.29 lakh to Rs 9.74 lakh (ex-showroom), is a more convincing compact sedan than the Tigor was. Its modern design, well-equipped cabin, comfortable ride and, most importantly, useful boot space despite the CNG setup give it plenty going for it. The fact that Tata offers the CNG powertrain with higher-spec variants also means buyers don't have to sacrifice features for lower running costs. The CNG-AMT powertrain, however, takes some shine off the package. It is fine for everyday driving, but feels out of breath if you ask more from it. All of these make it better suited to relaxed city driving than frequent highway use.
There are alternatives in the compact sedan space with their own strengths and weaknesses, but the Aeris does have price on its side. It undercuts rivals and feels like good value for what it offers.
