Toyota’s two most affordable cars come from the same roots, yet they cater to slightly different tastes. The Glanza is the brand’s premium hatchback, sleek and easy to live with in the city. The Taisor takes much the same foundation and dresses it up as a stylish compact crossover, with a raised stance and a more rugged look. Both are built by Maruti Suzuki and share a great deal beneath the surface. The timing of this comparison is especially interesting. In October 2026, Toyota launched an updated Glanza with an all-new 1.2-litre three-cylinder engine that promises noticeably better fuel economy than before. The Taisor, meanwhile, carries on with its familiar 1.2-litre four-cylinder petrol and the punchier 1.0-litre turbo-petrol option. So, with the Glanza now running a newer, thriftier engine, how do the two stack up when it comes to fuel costs? Over the following sections, we’ll explore their claimed and tested mileage, the monthly spend you can expect and where their prices sit, along with a few useful pointers for anyone shopping in the used market.

Toyota Glanza vs Toyota Taisor: Specifications
Here’s where the latest update changes the picture. The new Glanza runs a 1.2-litre, three-cylinder Z-series engine making 83 PS and 112 Nm, and it now offers an AMT with CNG for the first time. The Taisor sticks with the older 1.2-litre, four-cylinder unit, which is a little stronger at 90 PS, and adds a 100 PS turbo-petrol that the Glanza doesn’t get.
| Specification | Toyota Glanza (2026) | Toyota Taisor |
|---|---|---|
| 1.2L petrol | 3-cylinder, 83 PS / 112 Nm | 4-cylinder, 90 PS / 113 Nm |
| 1.0L turbo-petrol | Not offered | 100 PS / 148 Nm |
| CNG | 70 PS / 102 Nm | Offered on the 1.2L |
| Petrol gearboxes | 5-speed MT or AMT | 5-speed MT or AMT (1.2L); 5-speed MT or 6-speed AT (turbo) |
| CNG gearboxes | 5-speed MT or AMT | 5-speed MT |
| Fuel tank | 37 litres | 37 litres |
The Glanza’s new engine trades a bit of outright power for better efficiency, while the Taisor gives you more choice and more performance, especially if you opt for the turbo.

Toyota Glanza vs Toyota Taisor: ARAI Mileage Figures
The new engine gives the Glanza a clear advantage. Its petrol AMT is now rated at 24.77 km/l, and the CNG AMT at an impressive 34.47 km/kg, which puts it among the most efficient cars in its class. The Taisor’s figures are still very respectable, but they sit a step behind.
| Variant | Glanza (2026) | Taisor |
|---|---|---|
| 1.2L petrol MT | 23.80 km/l | 21.79 km/l |
| 1.2L petrol AMT | 24.77 km/l | 22.89 km/l |
| 1.0L turbo MT | Not offered | 21.5 km/l |
| 1.0L turbo AT | Not offered | 19.86 km/l |
| CNG MT | 33.61 km/kg | 28.51 km/kg |
| CNG AMT | 34.47 km/kg | Not offered |
For context, the previous Glanza with the four-cylinder engine was rated at 22.35 km/l with the manual and 22.94 km/l with the AMT, so the update has brought a healthy jump.
Toyota Glanza vs Toyota Taisor: Real World Fuel Efficiency
Since the updated Glanza has only just gone on sale, it hasn’t been through real-world testing yet. What we do have are results for the outgoing Glanza, which used the very same four-cylinder engine the Taisor still runs today. That gives us a fair, like-for-like starting point.
In testing, the outgoing Glanza manual returned about 13.8 km/l in the city and 17.5 km/l on the highway, while its AMT managed roughly 11.86 km/l and 17.21 km/l. With the same engine, the Taisor 1.2 manual came in at around 13.5 km/l in town and 20 km/l on the highway, and its AMT at about 13 km/l and 18.8 km/l.
| Version | City | Highway | 50:50 mixed |
|---|---|---|---|
| Glanza 1.2 MT (previous engine) | 13.80 km/l | 17.50 km/l | 15.43 km/l |
| Glanza 1.2 AMT (previous engine) | 11.86 km/l | 17.21 km/l | 14.04 km/l |
| Taisor 1.2 MT | 13.50 km/l | 20.00 km/l | 16.12 km/l |
| Taisor 1.2 AMT | 13.00 km/l | 18.80 km/l | 15.37 km/l |
| Taisor 1.0 turbo MT | 10.90 km/l | 16.70 km/l | 13.19 km/l |
| Taisor 1.0 turbo AT | 10.17 km/l | 15.35 km/l | 12.23 km/l |
With the older shared engine, the two were really quite close, and the small differences mostly reflect different test conditions rather than any real advantage. The turbo Taisor, as you’d expect, uses a fair bit more fuel in exchange for its extra punch.
The new Glanza is where things should start to shift. Its claimed figures have risen by roughly 1.5 to 2 km/l over the old engine, so once real-world numbers arrive, it could well pull ahead of the Taisor 1.2. Until then, it’s best to treat the figures above as a reliable baseline rather than the final word.

Toyota Glanza vs Toyota Taisor: Fuel Cost Comparison
To turn these numbers into something you can plan around, imagine driving 1,000 km a month with an equal share of city and highway, or 12,000 km over a year. We’ve priced petrol at ₹100 a litre for easy reckoning, so feel free to adjust it to the rate in your area.
| Version | Mixed mileage | Cost per km | Monthly (1,000 km) | Yearly (12,000 km) |
|---|---|---|---|---|
| Glanza 1.2 MT (previous engine) | 15.43 km/l | ₹6.48 | ₹6,480 | ₹77,764 |
| Glanza 1.2 AMT (previous engine) | 14.04 km/l | ₹7.12 | ₹7,121 | ₹85,454 |
| Taisor 1.2 MT | 16.12 km/l | ₹6.20 | ₹6,204 | ₹74,448 |
| Taisor 1.2 AMT | 15.37 km/l | ₹6.51 | ₹6,506 | ₹78,072 |
| Taisor 1.0 turbo MT | 13.19 km/l | ₹7.58 | ₹7,581 | ₹90,972 |
| Taisor 1.0 turbo AT | 12.23 km/l | ₹8.17 | ₹8,174 | ₹98,088 |
With the same 1.2 engine, the monthly difference between the two is only a few hundred rupees either way, which most owners would hardly notice. The bigger jump comes with the Taisor turbo, which can add roughly ₹1,000 to ₹2,000 to your monthly bill compared to a 1.2.
If keeping fuel costs as low as possible is your priority, the CNG versions are the ones to look at. The new Glanza CNG, now with an AMT option, has the strongest claimed figures of the lot and should make for a particularly economical daily runabout.
Toyota Glanza vs Toyota Taisor: Price Comparison
The Glanza is the more affordable way into a Toyota, with the updated model priced from ₹6.99 lakh to ₹10.98 lakh. The Taisor starts a little higher at about ₹7.25 lakh and stretches to around ₹12.23 lakh for the top turbo automatic (all prices ex-showroom).
| Car | Approx. ex-showroom price |
|---|---|
| Toyota Glanza (2026) | ₹6.99 lakh to ₹10.98 lakh |
| Toyota Taisor | ₹7.25 lakh to ₹12.23 lakh |
At the lower end, the gap between them is fairly small, so it really comes down to what you’d prefer to drive. The Glanza now brings the newer, more efficient engine, plus features like ventilated front seats and Level 2 ADAS on its top trim. The Taisor counters with a taller, crossover-style stance and the option of a lively turbo engine, which many buyers find hard to resist.
Buying used? With the facelifted Glanza now in showrooms, pre-owned examples of the earlier four-cylinder Glanza are a great-value option, and you’ll find plenty of them on Spinny. The Taisor arrived in 2024, so most used examples are fairly recent and low on kilometres. Before you commit, have a good look through the inspection report and service history, and if you’re considering a turbo automatic, check how smoothly it shifts during your test drive. Spinny Assured cars come with a 200-point inspection, a 1-year warranty, fixed pricing and a 5-day money-back guarantee (terms apply), while select Assured+ cars are backed by a longer 3-year warranty.
Summary
For a long time, the Glanza and the Taisor were evenly matched on fuel, since they shared the same engine and returned very similar figures in real-world testing. The October 2026 update has tipped the balance, with the Glanza’s new three-cylinder engine promising a meaningful step up in efficiency, both with petrol and with CNG.
If saving on fuel sits at the top of your list, the new Glanza, particularly in CNG form, looks like the smarter pick, and it’s also the cheaper of the two to buy. The Taisor still has plenty going for it, though. Its crossover styling, higher seating position and the option of a peppy turbo engine make it the more exciting choice, as long as you’re comfortable with slightly higher running costs, especially if you go for the turbo.

FAQs about Glanza and Taisor Mileage Comparison
Q. How does the new three-cylinder Glanza compare with the older four-cylinder model?
The new Z-series engine is slightly less powerful, at 83 PS compared to the older engine’s 90 PS, but it’s been designed with efficiency in mind. Its claimed figures are up by roughly 1.5 to 2 km/l across the board. For most everyday city and highway driving, the small dip in power is unlikely to be very noticeable.
Q. Is a used four-cylinder Glanza still worth considering?
Very much so, especially now that the facelift has arrived and prices of the older model are becoming more attractive. It uses the same proven engine that still powers the Taisor, delivered around 15 km/l in mixed real-world driving with the manual, and has a well-earned reputation for smoothness and reliability.
Q. What’s new with the Glanza CNG?
For the first time, the Glanza CNG is available with an AMT, so you can enjoy CNG’s low running costs without having to work a clutch in traffic. It also has the highest claimed figure in the range, at 34.47 km/kg, which should make it one of the most affordable cars to run in its segment.
Q. Will the Taisor get the Glanza’s new Z-series engine?
Toyota hasn’t announced anything along those lines yet. For now, the Taisor continues with its 1.2-litre four-cylinder engine and the 1.0-litre turbo-petrol, so if the newer engine is important to you, the Glanza is currently the only Toyota of the two that offers it.
Q. Is the Taisor turbo worth the extra fuel cost?
The turbo brings noticeably stronger acceleration, which helps with overtaking on highways, but it also costs roughly ₹1,000 to ₹2,000 more each month to run than the 1.2 in our estimates. If performance matters to you, many owners feel the trade-off is worth it.
Q. Which of the two is better suited to a small family?
Both seat five comfortably and offer the same 37-litre fuel tank, so it largely comes down to preference. The Glanza is easier on the wallet and slightly more efficient, while the Taisor’s raised driving position and crossover design may appeal if you like the feel of an SUV or often drive on rough roads.
