Walk into any Tata showroom with a modest budget, and two cars are likely to catch your eye straight away. The Tiago is the familiar, easy-going hatchback that many first-time buyers start with, while the Punch offers a taller, SUV-like stance for not a great deal more money. Both draw their power from Tata’s 1.2-litre, three-cylinder petrol engine, which makes their mileage story especially interesting to unpack. It’s been a big year for both. The Punch was given a comprehensive facelift in January 2026, bringing a fresh look, a 5-star Bharat NCAP rating, a brand-new turbo-petrol engine and a CNG automatic. The Tiago followed with a thorough makeover of its own in May 2026, keeping its proven petrol and CNG line-up intact. So, does the Punch’s extra size cost you anything at the pump, or does the lighter Tiago keep its edge? We’ll look at what each one promises on paper, how they behave in everyday driving, what they’ll cost you to run every month and where their prices sit.

Tata Punch vs Tata Tiago: Specifications
The engine bay is where these two feel most like family. Each runs the same 1.2-litre petrol unit, though the Punch’s version is tuned for a touch more output, and both come with factory-fitted twin-cylinder CNG paired to either a manual or an AMT. What really separates them is the Punch’s new 120 PS turbo-petrol, an option the Tiago simply doesn’t have.
| Specification | Tata Punch | Tata Tiago |
| 1.2L petrol | 88 PS / 115 Nm | 86 PS / 113 Nm |
| 1.2L turbo-petrol | 120 PS / 170 Nm | Not offered |
| 1.2L CNG | 73.5 PS / 103 Nm | 73.4 PS / 95 Nm |
| Petrol and CNG gearboxes | 5-speed MT or AMT | 5-speed MT or AMT |
| Turbo gearbox | 6-speed MT | Not offered |
| Petrol tank | 37 litres | 35 litres |
| Boot space (petrol) | 366 litres | 242 litres |
Beyond the numbers, the Punch is the taller and roomier of the two, with a noticeably larger boot. The Tiago, being smaller and lower, has less to carry around, which is something to keep in mind as we get into the mileage figures.
Tata Punch vs Tata Tiago: ARAI Mileage Figures
Glance at the official numbers and the Punch actually comes out slightly ahead with petrol, at around 20.1 km/l against the Tiago’s 19.01 km/l. Switch over to CNG, though, and the tables turn, with the Tiago’s CNG automatic claiming an impressive 28.06 km/kg.
| Variant | Punch | Tiago |
| Petrol MT | About 20.1 km/l | 19.01 km/l |
| CNG MT | 26.99 km/kg | 26.49 km/kg |
| CNG AMT | About 26 km/kg | 28.06 km/kg |
| Turbo-petrol MT | Not yet announced | Not offered |
Tata hasn’t shared a certified figure for the Punch’s new turbo-petrol yet. As with any lab number, these are best treated as a starting point, since real traffic, a full cabin and the air-conditioner all have their say.

Tata Punch vs Tata Tiago: Real World Fuel Efficiency
Here’s where things get a little surprising. Despite being the bigger car, the Punch petrol manual held its own in real-world testing, returning about 13.86 km/l in town and 17.08 km/l out on the highway. The Tiago petrol manual came in just behind, at roughly 13.3 km/l and 16.6 km/l. The Punch AMT, meanwhile, was the steadiest of the lot in traffic, managing around 14.42 km/l in the city and 15.89 km/l on the highway.
On CNG, the picture shifts depending on the gearbox. The Punch CNG manual was a real standout, stretching each kilo to about 20.7 km in the city and a remarkable 31 km on the highway. The Tiago CNG manual came close on the open road at about 33 km/kg but fell behind in town at 17 km/kg. With the AMT, the two were very evenly matched.
| Version | City | Highway | 50:50 mixed |
| Punch petrol MT | 13.86 km/l | 17.08 km/l | 15.30 km/l |
| Punch petrol AMT | 14.42 km/l | 15.89 km/l | 15.12 km/l |
| Tiago petrol MT | 13.3 km/l | 16.6 km/l | 14.77 km/l |
| Punch CNG MT | 20.7 km/kg | 31 km/kg | 24.82 km/kg |
| Punch CNG AMT | 18.87 km/kg | 25.36 km/kg | 21.64 km/kg |
| Tiago CNG MT | 17 km/kg | 33 km/kg | 22.44 km/kg |
| Tiago CNG AMT | 21.1 km/kg | 22 km/kg | 21.54 km/kg |
A small word of caution is in order. These results come from different tests carried out at different times, and most of the petrol figures were recorded before each car’s 2026 update. Since the engines themselves haven’t changed, they still offer a fair guide, but the gap between the two is small enough that your own driving style could easily tip the balance either way. We’re still waiting on real-world numbers for the Punch’s new turbo-petrol. With its extra power, it may well turn out to be the thirstiest of the bunch, especially in stop-and-go traffic.
Tata Punch vs Tata Tiago: Fuel Cost Comparison
Numbers on a page only mean so much until you see them as rupees. For this, we’ve pictured a typical month of 1,000 km, shared equally between city roads and highways, adding up to 12,000 km over the year. Petrol is pegged at ₹100 a litre and CNG at ₹80 a kilo, so do tweak these to match the rates near you.
| Version | Mixed mileage | Cost per km | Monthly (1,000 km) | Yearly (12,000 km) |
| Punch petrol MT | 15.30 km/l | ₹6.53 | ₹6,535 | ₹78,419 |
| Punch petrol AMT | 15.12 km/l | ₹6.61 | ₹6,614 | ₹79,368 |
| Tiago petrol MT | 14.77 km/l | ₹6.77 | ₹6,772 | ₹81,264 |
| Punch CNG MT | 24.82 km/kg | ₹3.22 | ₹3,223 | ₹38,673 |
| Punch CNG AMT | 21.64 km/kg | ₹3.70 | ₹3,697 | ₹44,364 |
| Tiago CNG MT | 22.44 km/kg | ₹3.56 | ₹3,565 | ₹42,778 |
| Tiago CNG AMT | 21.54 km/kg | ₹3.71 | ₹3,714 | ₹44,563 |
On petrol, the difference between these two barely registers, at roughly ₹240 a month in the Punch’s favour. The more meaningful decision is whether to go for CNG at all, since doing so brings the monthly bill down by around half in either car. Among the CNG versions, the Punch manual came out as the cheapest to run in these tests, while the two AMTs ended up almost neck and neck. One practical point worth knowing: with a CNG range of roughly 175 to 185 km per fill in the Punch AMT, you’ll be visiting the CNG pump fairly often if you drive a lot.

Tata Punch vs Tata Tiago: Price Comparison
The Tiago remains the gentler entry point into Tata’s line-up, with prices running from about ₹4.69 lakh to ₹8.55 lakh and CNG versions beginning at around ₹5.79 lakh. The Punch opens at roughly ₹5.75 lakh, its CNG range sits between about ₹6.85 lakh and ₹10.77 lakh, and the new turbo-petrol arrived at ₹8.29 lakh (all prices ex-showroom).
| Car | Approx. ex-showroom price |
| Tata Tiago | ₹4.69 lakh to ₹8.55 lakh |
| Tata Tiago CNG | From ₹5.79 lakh |
| Tata Punch | From ₹5.75 lakh |
| Tata Punch CNG | ₹6.85 lakh to ₹10.77 lakh |
| Tata Punch turbo-petrol | From ₹8.29 lakh |
Since running costs are so close, the extra spend on a Punch is really about what you get beyond fuel economy. That means a higher seating position, more ground clearance for rough roads, a much bigger boot and the reassurance of a 5-star crash rating. The Tiago, on the other hand, is hard to beat if you mainly want a sensible, affordable car for city commutes.
Buying used? With the Tiago around since 2016 and the Punch since 2021, there’s no shortage of choice on Spinny, whether you’re after an older petrol or a more recent CNG model. Before you settle on one, give the inspection report a careful read, check the service history and, for a CNG car, ask to see the cylinder’s testing certificate. Spinny Assured cars are backed by a 200-point inspection, a 1-year warranty, fixed pricing and a 5-day money-back guarantee.
Summary
It’s easy to assume the bigger Punch would cost more to keep fuelled, but in practice the two are remarkably close. With petrol, the Punch even edged ahead slightly in testing, and with CNG, both cars bring running costs down to a level that’s hard to argue with. That leaves the choice resting on the kind of car you want rather than the mileage it returns. If you’d like a compact, wallet-friendly hatchback that slips easily through city traffic, the Tiago is still a very sensible buy. If you can stretch your budget a little, the Punch rewards you with more space, a commanding view of the road, a bigger boot and the option of a peppy turbo engine, all without asking much more at the fuel pump.

FAQs about Punch and Tiago Mileage Comparison
Q. Does the Punch’s SUV-style body make it less economical than the Tiago?
Not in any way you’d really notice. Even though the Punch is taller and roomier, it shares a very similar engine with the Tiago, and in real-world testing its petrol manual actually managed slightly better figures. Over a month of mixed driving, the difference works out to only a couple of hundred rupees.
Q. Should I pick the Punch CNG automatic or stick with the manual?
That mostly depends on how much you value convenience. The manual proved to be the more frugal of the two in testing, stretching each kilo of CNG noticeably further, particularly on the highway. The AMT, however, takes the strain out of crawling traffic, so if your daily drive involves a lot of stop-and-go, the small extra cost may well feel worthwhile.
Q. How often will I need to stop for CNG in the Punch?
A little more often than you might expect. The Punch iCNG AMT can cover roughly 175 to 185 km on a full fill of CNG, so regular highway drivers will be planning their stops fairly frequently. The good news is that the petrol tank is always there as a backup when a CNG station isn’t nearby.
Q. Is a turbo-petrol automatic on the cards for the Punch?
For now, the Punch’s new turbo-petrol is offered only with a 6-speed manual. Tata hasn’t announced an automatic version yet, so if you’d like two-pedal convenience in a Punch today, the regular petrol AMT or the CNG AMT are the options to explore.
Q. Is the Tiago CNG automatic a good choice for city driving?
It’s one of its strengths. In real-world testing, the Tiago CNG AMT returned about 21.1 km/kg in the city, which was noticeably better than the CNG manual in the same conditions. If most of your driving happens in town, it’s an easy one to recommend.
Q. Is a pre-owned Punch a better buy than a brand-new Tiago?
It can be, if you’re drawn to the Punch’s space and higher driving position. A used Punch from the past few years shares much the same engine and offers similar running costs, often at a price close to a new Tiago. Just look carefully at its condition and service records, and remember that a new Tiago gives you a full factory warranty and the latest features.
