1.2L Turbo Petrol — Real-World Mileage
The 1.2L Revotron turbo (120 PS / 170 Nm) is the peppier option. It has great city punchiness but the turbo demands fuel — especially in Sport mode or heavy traffic where the turbo spools frequently.
| Condition | 6MT (KMPL) | 6AMT (KMPL) | Notes |
|---|---|---|---|
| Heavy City Traffic (10-20 km/h) | 11-12 | 10-11 | Stop-go, turbo lag zone |
| Normal City (25-40 km/h) | 13-14 | 12-13 | Moderate traffic, AC on |
| Highway Cruising (80-100 km/h) | 18-20 | 16-18 | Sweet spot — low boost |
| Highway Fast (100-120 km/h) | 14-16 | 13-15 | Turbo on boost frequently |
| Mixed Driving Average | 13-15 | 12-14 | Real-world combined |
Mileage-Boosting Accessories
TUSA AC/DC Tyre Inflator — Auto Shutoff
Correct tyre pressure (33 PSI) = 2-3 KMPL better mileage. Under-inflated tyres are the #1 mileage killer. Check weekly.

NEODRIFT Magnetic Sunshade Set
Reduces parked cabin temperature by 10°C+. Less AC blast needed on restart = 0.5-1 KMPL saved per summer trip.
Buy on Amazon1.5L Diesel — Real-World Mileage
The 1.5L Revotorq diesel (116 PS / 260 Nm) is the mileage champion. The massive torque means less throttle input for the same speed — translating to genuinely impressive real-world numbers, especially on highway.
| Condition | 6MT (KMPL) | 6AMT (KMPL) | Notes |
|---|---|---|---|
| Heavy City Traffic (10-20 km/h) | 15-16 | 14-15 | Diesel torque helps in crawl |
| Normal City (25-40 km/h) | 17-18 | 16-17 | Comfortable 3rd-4th gear |
| Highway Cruising (80-100 km/h) | 23-25 | 21-23 | Sweet spot — 1800 RPM in 6th |
| Highway Fast (100-120 km/h) | 19-21 | 17-19 | Still impressive at speed |
| Mixed Driving Average | 17-19 | 16-18 | Best efficiency in segment |
💰 Diesel Highway Champion: On a pure highway run at 80-90 km/h, the Nexon diesel MT can deliver 24-25 KMPL consistently — that's a range of 1,050-1,100 km on a single 44L tank. Few cars at any price can match this highway efficiency.
ARAI vs Real-World — The Gap
The 18-22% gap is normal for turbocharged engines in Indian conditions. The turbo petrol has a larger gap because city driving keeps the turbo in its lag zone (below 1500 RPM), reducing efficiency.
Monthly Running Cost Comparison
Assuming 1,200 km/month mixed driving (Aug 2026 — Petrol ₹105/L, Diesel ₹92/L):
| Engine | Avg Mileage | Fuel/Month | Monthly Cost |
|---|---|---|---|
| 1.2 Petrol MT | 14 KMPL | 86 litres | ₹9,030 |
| 1.2 Petrol AMT | 13 KMPL | 92 litres | ₹9,660 |
| 1.5 Diesel MT | 18 KMPL | 67 litres | ₹6,164 |
| 1.5 Diesel AMT | 17 KMPL | 71 litres | ₹6,532 |
Diesel saves ₹2,900-3,100/month over petrol. Over 5 years that's ₹1.74-1.86 lakh — enough to justify diesel's ₹2L higher purchase price if you drive 12,000+ km/year.

Tips to Maximize Nexon Mileage
🔧 Tyre Pressure
Keep at 33 PSI all round. Under-inflated by 5 PSI = 2-3 KMPL drop. Check every Sunday.
🚗 Use Eco Mode
Eco mode limits turbo boost and throttle response — saves 1-2 KMPL in city consistently.
❄️ AC at 24°C
18°C vs 24°C costs 1 KMPL difference. Use recirculation in city — cools faster, less compressor load.
🛣️ Highway Sweet Spot
80-90 km/h in 6th gear is the efficiency sweet spot. Every 10 km/h above 100 costs 2 KMPL.
🔄 Timely Service
Clean air filter + fresh oil every 10K km. Clogged filter alone costs 1-2 KMPL on turbo engines.
⛽ Quality Fuel
Turbo petrol benefits from branded/high-octane fuel. Diesel: use branded outlets for cleaner injectors.
Frequently Asked Questions
What is the real mileage of Tata Nexon petrol?
The 1.2L turbo petrol MT delivers 12-14 KMPL in city and 17-20 KMPL on highway with AC on. AMT gets 1-2 KMPL less. Mixed driving average is 13-15 KMPL for manual — about 20% less than ARAI's 17.05 claim.
What is Nexon diesel real mileage?
The 1.5L diesel MT gives 16-18 KMPL city and 22-25 KMPL highway. This is exceptional for a sub-4m SUV. On pure highway at 80 km/h, it can touch 24-25 KMPL — translating to 1,000+ km range on a single 44L tank.
Nexon MT or AMT — which gives better mileage?
MT gives 1-2 KMPL better in all conditions. The AMT holds gears longer and shifts at higher RPMs, hurting efficiency. Exception: extreme stop-go traffic below 15 km/h where AMT's smooth creep can match MT. For mileage purists, always choose MT.
Is Nexon diesel worth the extra ₹2 lakh?
Yes if you drive 12,000+ km/year. Diesel saves ₹2,900-3,100/month in fuel. Break-even point: ~18-20 months. Over 5 years: ₹1.75L saved in fuel — nearly offsetting the ₹2L premium. Plus diesel's 260 Nm torque makes highway driving effortless.
What is the tank range of Tata Nexon?
44-litre tank. Petrol MT: 580-660 km (mixed). Diesel MT: 750-850 km (mixed). On pure highway, diesel can touch 1,000-1,100 km on a single tank — one of the best in any compact SUV.
How does Nexon mileage compare to Brezza and Venue?
Nexon petrol: 13-15 KMPL mixed (similar to Brezza 1.5 NA at 14-16). Nexon diesel: 17-19 KMPL mixed (Brezza has no diesel, Venue discontinued diesel). For diesel mileage, Nexon is the only option in segment — and it's excellent. Petrol-to-petrol, Brezza's NA engine is slightly more efficient in city.
