The Tata Aeris specifications start with a 1.2 litre petrol that makes 85 bhp and 113 Nm. The factory iCNG version makes 74 bhp and 96.5 Nm when it runs on gas. Both engines offer a five speed manual or a five speed AMT, and the CNG starts straight on gas rather than on petrol.
At 3995 mm long with a 2450 mm wheelbase, the Aeris uses its size well. The 419 litre boot is big for a sub four metre sedan, and clever twin cylinder packaging keeps that space on the CNG too. Ground clearance is 170 mm, and the petrol tank holds 35 litres.
Safety runs deep for the class. Six airbags, ABS with EBD and corner stability control, and ISOFIX mounts are standard from the base Smart. Electronic stability, hill hold and a tyre pressure monitor join from Pure Plus, and a 360 degree camera with a blind view monitor arrives on Creative.
Higher trims turn the Aeris into a well equipped small sedan. You get up to a 26.03 centimetre HD touchscreen, ventilated leatherette seats and a built in dashcam near the top. To weigh each feature against its cost, check Aeris prices trim by trim.
