Tata Motors is stepping up its game in the compact SUV-coupe segment with the much-awaited Tata Curvv, and one of its most exciting variants is the diesel engine paired with a DCT (Dual-Clutch Transmission). With a bold design, tech-laden cabin, and fuel-efficient powertrain, the Curvv is aimed at those who want a blend of style, comfort, and practicality.
But how fuel-efficient is the Tata Curvv Diesel DCT in real-world Indian driving conditions? Can it match the claimed mileage figures? In this blog, we dive deep into a comprehensive mileage test, performance insights, and whether this new entrant lives up to the expectations of urban commuters and highway cruisers alike.
Tata Curvv Diesel DCT: Quick Overview
The Tata Curvv is Tata Motors’ latest design-forward SUV with a coupe-like silhouette, which differentiates it from the boxy designs of typical rivals. Offered in petrol, diesel, and EV variants, it brings together style, substance, and segment-first tech.
Diesel DCT Variant Highlights:
- 1.5L Revotorq diesel engine
- Power: 115 PS
- Torque: 260 Nm
- Transmission: 6-speed DCT (wet clutch)
- Claimed mileage: ~21.2 kmpl (ARAI-certified)
Real-World Mileage Test: Conditions & Method
To assess the true fuel economy, we tested the Tata Curvv Diesel DCT under mixed driving conditions, including:
- City traffic: Bumper-to-bumper driving in Mumbai
- Open highway: 100+ km on the expressway
- Hilly terrain: Mild inclines and winding roads
- AC usage: 100% ON
- Load: Driver + 1 passenger + boot with approx. 30 kg luggage
Method:
- Full tank to full tank method used
- MID (Multi-Information Display) readings cross-checked
- Drove with and without Eco mode for accuracy
Mileage Results: Real Numbers That Matter
| Driving Condition | Distance (km) | Mileage (kmpl) |
|---|---|---|
| City (with Eco mode) | 62 | 17.4 |
| Highway (cruise at 90) | 104 | 23.8 |
| Hilly terrain | 48 | 16.2 |
| Combined (mixed route) | 214 | 19.5 |
Average Real-World Mileage: 19.5 kmpl — impressive for a DCT diesel setup in India.
Driving Experience: Smooth & Punchy
While mileage is important, how the vehicle drives plays an equally important role. The 1.5L diesel engine combined with the 6-speed DCT feels refined, responsive, and well-matched.
Observations:
- Gearshifts are smooth and fast, especially above 30 kmph
- Low-end torque is sufficient for city overtakes
- Eco mode offers better fuel economy but dulls throttle response
- Sport mode makes the SUV feel agile and eager
- Engine noise is minimal and vibration levels are well-contained
Despite being a diesel, the Curvv feels premium and vibration-free — a major plus for long-distance touring.
Tech & Features that Assist Efficiency
Several features in the Tata Curvv Diesel DCT help maximize efficiency:
Key Efficiency-Aiding Features:
- Eco driving mode with recalibrated throttle
- Auto start-stop system (useful in city traffic)
- Coasting function during downhill drives
- Gearshift indicator for manual override
- MID-based mileage coaching and real-time fuel monitor
Together, these features help drivers optimize their driving habits to extract maximum fuel economy.
Comfort on Long Drives
Mileage isn’t just about numbers — it’s about how effortless the drive feels. Tata has clearly paid attention to long-distance comfort in the Curvv.
Interior Comfort Insights:
- Well-bolstered ventilated front seats
- Spacious cabin with premium materials
- Large 10.25-inch touchscreen with wireless Apple CarPlay/Android Auto
- Multiple USB-C ports and a premium JBL sound system
- Rear AC vents and flat floor for enhanced passenger comfort
Whether you’re doing 20 km or 200, the Curvv remains composed, cushioned, and driver-friendly.
Ownership Costs: Diesel Efficiency Pays Off
Even though diesel fuel is slightly cheaper than petrol in many Indian states, modern diesel engines offer a clear advantage in fuel cost per kilometre.
Cost Analysis (Approx.):
- Diesel price: ₹90/litre
- Real-world mileage: 19.5 kmpl
- Fuel cost/km: ~₹4.61/km
Compared to a typical petrol SUV (~₹6–₹6.5/km), the diesel Curvv offers significant savings for high-mileage users, especially fleet operators and long-distance commuters.
How It Compares with Rivals
| Model | Fuel Type | Transmission | Real Mileage (kmpl) |
| Tata Curvv Diesel DCT | Diesel | DCT | 19.5 |
| Hyundai Creta 1.5 Diesel AT | Diesel | Torque Conv. | 17.5–18.5 |
| Kia Seltos Diesel AT | Diesel | Torque Conv. | 18.2–19 |
| Maruti Grand Vitara Hybrid | Petrol | e-CVT | 20–21 (city biased) |
With a DCT transmission and nearly 20 kmpl real mileage, the Curvv outshines many rivals offering torque converters or less efficient hybrids.
