Tata Sierra Mileage Controversy: ARAI Reveals Actual Figures, Not 29.99 KMPL

• ARAI data obtained via RTI shows Tata Sierra's 1.5L turbo petrol delivers 13.5 kmpl, and 1.5L diesel 18.8 kmpl.
• These figures are significantly lower than Tata Motors' marketing claims of 29.9 kmpl from NATRAX track tests.
• The company had not publicly released official ARAI mileage figures since the SUV's November 2025 launch.
• Auto experts suggest NATRAX figures were for marketing, with real-world experience closer to ARAI data.
• Tata Sierra, priced 13-25 lakh, competes with Hyundai Creta and Kia Seltos, offering modern features and a 5-star GNCAP rating.
