The Maruti Wagon R and Tata Tiago are practical hatchbacks for buyers seeking low running costs, easy handling in towns, and versatility for family use. The spacious Wagon R offers both 1.0-litre and 1.2-litre petrol engines and comes with both manual and AMT gearboxes. One of the few hatchbacks with a factory-fitted CNG automatic gearbox, the Tata Tiago is equipped with a 1.2-litre engine and offers manual and AMT versions in both petrol and CNG.
Their fuel efficiency differs considerably. The Wagon R is lighter and tuned strongly for mileage, whereas the heavier Tiago offers stronger CNG performance and more transmission options. Since congestion, driving style, passenger load and air-conditioning use create a gap between claimed and actual mileage, this comparison examines their ARAI figures, real-world efficiency, fuel costs and prices.

Maruti Wagon R vs Tata Tiago Specs
The table below highlights the key specification differences between the Maruti Wagon R and Tata Tiago:
| Specification | Maruti Wagon R | Tata Tiago |
| Engine options | 1.0-litre petrol; 1.2-litre petrol; 1.0-litre petrol-CNG | 1.2-litre petrol; 1.2-litre petrol-CNG |
| Displacement | 998 cc; 1197 cc | 1199 cc |
| Petrol power | 1.0-litre: around 67 PS; 1.2-litre: 90.9 PS | 86 PS |
| CNG power | Around 57 PS | 75.5 PS |
| Petrol torque | 1.0-litre: 89 Nm; 1.2-litre: 113 Nm | 113 Nm |
| CNG torque | Around 82 Nm | 96.5 Nm |
| Transmission | 5-speed MT; 5-speed AMT; CNG gets MT only | 5-speed MT and 5-speed AMT with petrol and CNG |
| Drive layout | Front-wheel drive | Front-wheel drive |
| Approximate kerb weight | 810–850 kg | Around 982 kg, depending on variant |
| Petrol tank capacity | 32 litres | 35 litres |
| CNG tank capacity | 60 litres water equivalent | 60 litres water equivalent |
The Wagon R’s most notable advantage is its weight. The Wagon R can weigh over 100 kg less than the Tiago, which means the engine has less mass to push while accelerating. With its 1.0-litre engine for relaxed urban use, adding a 1.2-litre engine would make it more powerful without hurting fuel economy too much. The petrol Tiago delivers 86 PS and 113 Nm. In CNG form, it is now much faster than the Wagon R’s CNG and more suitable for carrying passengers, luggage, or climbing steep hills, and it is also more thirsty.
Both cars offer a petrol AMT, but only the Tiago offers a CNG AMT. The Tiago therefore suits buyers who want low CNG running costs without operating a clutch, while the Wagon R CNG remains the mileage-focused manual choice. The Wagon R’s tall body also improves visibility and urban usability, whereas the Tiago feels more settled at highway speeds. In simple terms, the Wagon R prioritises efficiency, and the Tiago offers a stronger, more substantial driving experience.
Maruti Wagon R vs Tata Tiago: ARAI Mileage Figures
Across the variants we can compare, the Wagon R wins in all of them. For example, the 1.0-litre AMT gives the best mileage of 25.19 km/l, while the Tiago with manual or AMT transmission provides around 19 km/l mileage. For manual CNG vehicles, the Wagon R claims 3.47 km/kg compared to the Tiago’s 0.49 km/kg. The new Tiago continues to use the same engines and gearboxes as the old generation. Hence, we will stick to the tried-and-tested mileage figures.
| Engine and Transmission | Fuel Type | Maruti Wagon R ARAI Mileage | Tata Tiago ARAI Mileage |
| 1.0-litre manual | Petrol | 24.35 km/l | — |
| 1.0-litre AMT | Petrol | 25.19 km/l | — |
| 1.2-litre manual | Petrol | 23.56 km/l | 19.01 km/l |
| 1.2-litre AMT | Petrol | 24.43 km/l | 19.00 km/l |
| CNG manual | Petrol-CNG | 33.47 km/kg | 26.49 km/kg |
| CNG AMT | Petrol-CNG | — | 28.06 km/kg |
ARAI testing does not cover long periods of idling, congested roads, short distances, or extensive air-conditioner use, so owners should not expect similar performance year-round. However, the gap in figures clearly suggests that the Wagon R will do even better in real-life situations. An AMT performed on the same standards as a manual transmission vehicle without fighting stop-and-go traffic and hard acceleration would work similarly or even achieve better efficiency while driving.

Maruti Wagon R vs Tata Tiago: Real World Fuel Efficiency
Real-world petrol mileage confirms the Wagon R’s advantage, although the difference is smaller than the official figures suggest. Its manual normally returns around 14–16 km/l in dense city traffic and 19–21 km/l on an open highway, while the AMT delivers approximately 13.5–15 km/l and 18.5–20 km/l respectively. Tiago owners can generally expect 13–15 km/l in the city and 17–19 km/l on highways from the manual. Its AMT usually returns around 12–14 km/l and 16–18 km/l. These are practical ranges, not guaranteed results.
Petrol Real-World Mileage
| Driving Condition | Maruti Wagon R Petrol | Tata Tiago Petrol |
| City | Manual: 14–16 km/l; AMT: 13.5–15 km/l | Manual: 13–15 km/l; AMT: 12–14 km/l |
| Highway | Manual: 19–21 km/l; AMT: 18.5–20 km/l | Manual: 17–19 km/l; AMT: 16–18 km/l |
| Representative mixed average | Manual: around 17 km/l; AMT: 16–17 km/l | Manual: around 15 km/l; AMT: around 14 km/l |
| Approximate petrol-tank range | Around 510–560 km | Around 490–525 km |
CNG Real-World Mileage
| Driving Condition | Maruti Wagon R CNG Manual | Tata Tiago CNG |
| City | 22–25 km/kg | Manual: 20–22 km/kg; AMT: 21–23 km/kg |
| Highway | 26–30 km/kg | Manual: 24–26 km/kg; AMT: 25–27 km/kg |
| Representative mixed average | Around 25 km/kg | Manual: around 22 km/kg; AMT: around 23 km/kg |
| Practical CNG-only range | Around 200–250 km, depending on the fill | Around 210–270 km, depending on the fill |
CNG also operates by the same principles. The Wagon R offers a higher range per kilogram and is better when keeping fuel expenses down is the top priority. The Tiago uses somewhat more CNG and is less troublesome in terms of passenger comfort and altitude, while its AMT removes the need to use the clutch in traffic. The CNG range varies with the pressure at the filling station, the ambient temperature, and the amount of gas left in the cylinder, so calculated figures using the full-to-full method are more precise.

Maruti Wagon R vs Tata Tiago: Fuel Cost Comparison
This calculation assumes monthly driving of 1,500 km, petrol at ₹112.02 per litre and CNG at ₹95.75 per kg. It uses representative mixed mileage of 17 km/l for the Wagon R petrol, 15 km/l for the Tiago petrol, 25 km/kg for the Wagon R CNG and 22 km/kg for the Tiago CNG. Actual costs will change with the powertrain, location, traffic and fuel price.
| Cost Detail | Wagon R Petrol | Tiago Petrol | Wagon R CNG | Tiago CNG |
| Monthly running | 1,500 km | 1,500 km | 1,500 km | 1,500 km |
| Monthly fuel use | 88.24 litres | 100 litres | 60 kg | 68.18 kg |
| Average monthly fuel cost | ₹9,884 | ₹11,202 | ₹5,745 | ₹6,528 |
| Average annual fuel cost | ₹1.19 lakh | ₹1.34 lakh | ₹68,940 | ₹78,341 |
| Five-year fuel cost | ₹5.93 lakh | ₹6.72 lakh | ₹3.45 lakh | ₹3.92 lakh |
When driving, a Wagon R petrol costs around ₹1,318 per month, or about ₹79,000 in 5 years, compared to a Tiago petrol. The Wagon R CNG can save an estimated ₹783 per month, or ₹47,000 in 5 years. CNG consumption on both cars is significantly lower, but buyers should keep in mind the vehicle cost and CNG availability in their area when deciding. The lower the running costs, the longer it will take to repay the initial cost. This table excludes maintenance and insurance expenses, as it only covers fuel costs.

Maruti Wagon R vs Tata Tiago Price
| Model | Variants | Ex-Showroom Price |
| Maruti Wagon R | LXi to ZXi+ | ₹4.99 lakh–₹6.95 lakh |
| Tata Tiago | Smart to Creative+ | ₹4.69 lakh–₹8.55 lakh |
The Tiago is priced somewhat lower; however, it covers a much wider range, including expensive combinations with CNG and the CNG-AMT. Meanwhile, the Wagon R has a smaller range, and its top variants are also affordable. Instead of comparing only the starting price, consumers should review the corresponding fuel and transmission combinations. For instance, the CNG automatic Tiago has no direct equivalent in the Wagon R, while the latter’s 1.0-litre and 1.2-litre petrol engines offer a better balance of price, performance, and efficiency.
Summary
The Maruti Wagon R is the clear mileage winner. It delivers better claimed and real-world efficiency with petrol and manual CNG, and its lighter construction helps reduce monthly fuel expenditure. The Tata Tiago is less economical, but it offers stronger CNG performance, a more planted highway feel and the rare convenience of a factory-fitted CNG AMT. Choose the Wagon R when maximum mileage, easy urban use and lower fuel costs matter most. Choose the Tiago if stronger performance, automatic CNG convenience and a more substantial driving experience are worth the additional running cost.
