Turbo Petrol Powertrains Compared
All three pack modern turbo petrol engines tuned for Indian roads:
- Renault Duster 2026: The 1.3L Turbo TCe 160 (main turbo petrol) delivers 160-163 bhp and 280 Nm torque. Paired with 6-speed MT or DCT. A lighter 1.0L turbo option (99 bhp) exists but we focus on the powerful 1.3L here.
- Tata Sierra 2026: The new 1.5L Hyperion TGDi turbo petrol produces 158-160 bhp and 255 Nm. Available with 6-speed AT or manual options in higher trims.
- Skoda Kushaq 2026 Facelift: Offers two choices – efficient 1.0L TSI (115 bhp, 178 Nm) with 6MT/8AT, and punchier 1.5L TSI (150 bhp, 250 Nm) with 7DCT.
The Duster feels the most powerful on highways, while the Kushaq’s 1.0L is refined for city use. Sierra’s turbo is smooth but slightly behind in outright punch.
Mileage: The Efficiency Champion Revealed
This is the big question in Duster vs Sierra vs Kushaq mileage battle. ARAI-claimed figures for turbo petrol variants (real-world drops 2-4 kmpl in traffic):
- Skoda Kushaq: 1.0L TSI MT – 19.66 kmpl | 8AT – 19.09 kmpl 1.5L TSI DCT – 18.72 kmpl Clear winner for efficiency.
- Renault Duster: 1.3L Turbo MT – 17.75 kmpl | DCT – 18.45 kmpl (up to 18.85 in some tests).
- Tata Sierra: 1.5L Turbo Petrol – 15.3-17.4 kmpl (ARAI; real-world often 12-15 kmpl).
The Kushaq stands out as the most efficient turbo petrol SUV here, thanks to its lighter 1.0L engine and advanced 8-speed torque converter. Duster is a close second with its refined 1.3L, while Sierra lags slightly in claimed figures despite its modern direct-injection tech.
