Tata Aeris CNG's ARAI mileage is 26.2-27.8 km/kg, well short of the viral 39 km/kg figure
Tata Motors' Aeris CNG AMT managed only 25.6 km/kg in CarWale's independent test in mixed driving. The 39 km/kg figure came from a reviewer's highway test drive.

Why it matters for the brand
When benchmarking the Aeris CNG against rivals, use ARAI and independent mixed-driving numbers (26.2-27.8 and 25.6 km/kg) rather than single-reviewer highway claims, which overstate real-world efficiency by about 11 km/kg or more.
What to track next
- A Tata Motors statement or clarification that addresses the 39 km/kg claim directly
- Independent mileage tests from other outlets that land above or below CarWale's 25.6 km/kg
- Owner-reported real-world km/kg figures appearing on forums and in review comment sections
- Advertising-standards complaints or a regulator query over mileage claims
- Rival CNG launches or campaigns that reference certified versus real-world mileage
Likely next moves
Our read of what comes next — analysis, not reported by the source.
- Tata Motors is likely to keep its official communication anchored on the ARAI-certified 26.2 to 27.8 km/kg and avoid endorsing the 39 km/kg figure.
- Auto publications and reviewers are likely to run more mixed-condition mileage tests of the Aeris CNG, with results expected to cluster near CarWale's 25.6 km/kg for the AMT.
- Tata Motors dealers may be briefed to quote certified figures and explain how highway and city driving differ, to head off buyer disappointment at delivery.
- Rival CNG carmakers may point to their own certified mileage in sales pitches, using the gap between viral and certified Aeris numbers as a talking point.
- Prospective buyers are likely to shift from the headline 39 km/kg to weighing the certified range against running costs, the 1.2-litre engine and the 210-litre usable boot.
