Quick answer
Shortlist the Tata Nexon if you need a diesel option or want to compare several petrol gearbox choices. Shortlist the current Maruti Brezza if its 1.5-litre petrol automatic, new turbo manual or revised CNG layout suits your needs. Neither should be chosen from an old comparison that ignores the July 2026 Brezza update.
For family use, compare the exact fuel, gearbox and trim within your budget, then check seating, luggage and local workshop access. This article uses manufacturer information and practical buying checks. It does not claim first-hand road-test results or guaranteed ownership savings.
The Brezza update changes this comparison
Suzuki's 25 July 2026 announcement identifies the new Brezza's 1.0-litre turbo-petrol, 1.5-litre petrol and 1.5-litre CNG choices. It lists six-speed manual transmissions, a six-speed automatic for the 1.5 petrol, and an underbody CNG tank arrangement.
Those details matter because older reviews can describe a different gearbox, CNG installation and safety position. Ask which version the dealer is quoting. A stock-clearance offer for an earlier car should not be compared as though it has every feature of the updated model.
Tata's current Nexon information continues to distinguish petrol, diesel and iCNG versions. Keep the Nexon.ev outside this comparison: an electric SUV needs a different charging and running-cost assessment. Similar styling does not make all fuel types interchangeable purchases.
Start with the fuel and transmission you need
Tata's current specification page lists a 1.2-litre turbo petrol, 1.5-litre diesel and 1.2-litre turbo iCNG. Petrol gearbox choices include manual, AMT and DCT combinations; diesel has manual and AMT, while iCNG is listed with a six-speed manual.
| Requirement | Nexon range to consider | Current Brezza range to consider |
|---|---|---|
| Petrol automatic | Confirm AMT or DCT trim | 1.5 petrol six-speed automatic |
| Petrol manual | Confirm five- or six-speed combination | 1.5 petrol or 1.0 turbo manual |
| Diesel | Manual or AMT choices | Not in the announced current range |
| Factory CNG | iCNG six-speed manual | S-CNG six-speed manual |
| Electric ownership | Assess Nexon.ev separately | Not a like-for-like choice here |
Gearboxes vary by trim. Confirm the exact configuration on the quotation before booking.
Petrol automatics need a proper back to back drive
The badge automatic does not describe one mechanical system. Nexon's AMT and DCT choices are different from each other, and Brezza's listed six-speed automatic is another comparison. Test the actual gearbox you are considering, not a higher-priced demonstration car with different hardware.
Begin with slow movement, parking, reversing and gentle acceleration. Then check the behaviour on your normal type of road at lawful speeds. Note whether you can control the car comfortably and whether the usual passengers find the movement acceptable.
Ask for the operating guidance and scheduled maintenance requirements. Do not assume one gearbox is unsuitable simply because of its label, or that another will feel perfect in all traffic. Your route, driving style and budget should guide the final choice after the test drive.
Compare turbo manuals without mixing engine figures
Both ranges now give a petrol-manual buyer a turbo option to inspect. Compare the relevant engines and trims rather than treating the Brezza range as only the earlier 1.5-litre petrol proposition. The July update makes that older shortcut inaccurate.
Check clutch effort, low-speed response and how easily you can make normal progress without frequent uncomfortable gear changes. Test with a sensible passenger load where the dealer permits it. Avoid a demonstration focused only on a brief burst of acceleration.
Power and torque figures do not establish cabin noise or ride comfort. Those judgements need an appropriate test drive.
Diesel is a clear reason to include the Nexon
If diesel is a firm requirement, the current Nexon range gives you an option that the announced Brezza range does not. First check that diesel makes sense for your annual distance, journey length, ownership period and applicable local rules.
Request the owner's guidance for emissions-system operation and the service schedule. Explain whether your week consists mainly of short errands or longer runs. Do not decide from a single annual-kilometre threshold without considering how those kilometres are accumulated.
Compare the diesel purchase premium against realistic fuel costs, maintenance and finance. Use current local pump prices and labelled consumption assumptions. A lower fuel bill does not by itself prove the whole vehicle will cost less to own over your planned period.
CNG buyers should bring their luggage
The new Brezza's underbody CNG arrangement makes older luggage-space assumptions unreliable. Tata separately lists the Nexon's CNG boot capacity at 321 litres, compared with 382 litres for petrol and diesel. These published figures are not a substitute for loading your actual bags.
Check the usable floor, access to the spare or repair equipment, folded-seat arrangement and where your regular luggage fits. Bring a pram or other bulky item if it will be carried often. A tank arrangement can change practicality without answering every loading question.
Both current CNG ranges are listed with manual gearboxes. If you want CNG without a clutch pedal, do not let a sales discussion imply an automatic combination exists without an exact manufacturer-backed order specification. A petrol automatic is a different fuel-cost decision.
Certified mileage is not your personal fuel bill
Maruti's July launch material quotes 26.9 km/kg for the updated Brezza S-CNG. It is a manufacturer-published efficiency figure, not a promise for congested commutes. Do not compare it directly with a petrol km/l number as if the fuel units were identical.
For a fair estimate, divide the local fuel price by a realistic consumption assumption in the matching unit. Multiply that cost per kilometre by your expected distance. Include petrol use where relevant and do not ignore detours or time spent obtaining CNG.
Run a lower-efficiency case as well as your preferred estimate. If the purchase only looks affordable under the most optimistic fuel assumption, reconsider the budget. Keep registration, insurance, interest, servicing and eventual resale separate from the fuel calculation.
Safety evidence needs the right model and assessment
Suzuki's July announcement states that the new Brezza achieved five stars under Bharat NCAP. Tata's current Nexon specification page also identifies a five-star Bharat NCAP rating. This means an old comparison that dismisses the updated Brezza using an earlier model's result is not a sound basis for choosing.
Stars alone do not explain every difference. Check the actual assessment records, tested versions, production coverage and adult and child results before making a score comparison. Do not add figures from different programmes or assume a star rating guarantees an injury-free collision.
Tata lists six airbags, three-point restraints and electronic stability control as standard on its current Nexon page. Confirm the exact safety equipment on both delivered variants. Check child-seat installation, restraint access and tyre condition during the pre-delivery inspection, not only the entertainment system.
Separate driver assistance from basic protection
A product page can display equipment that is restricted to selected trims or powertrains. Check cameras, parking assistance and ADAS individually on the current matrix. Do not assume every Nexon has all the equipment shown in its advertising imagery.
Ask for a parked demonstration of camera views and alerts before judging how useful they are. Read the operating limits for driver assistance. The driver remains responsible, and additional sensors do not replace careful observation, suitable speed or correct use of seat belts.
Compare the lower variants too. If your essential safety and convenience needs are met without an expensive cosmetic pack, the saved money can support insurance and maintenance. Do not spend beyond a comfortable budget simply to reproduce the showroom car's appearance.
Check rear seat comfort before comparing screens
Set the driver's seat correctly and then try the seat behind it. Bring regular rear passengers, particularly older family members or anyone who needs easier entry. Check foot space, head clearance, seat-belt reach and whether the door opens adequately in your parking space.
If five people will travel frequently, test the middle rear position rather than assuming two comfortable seats establish comfort for three. Fit the child seat you plan to use and check that nearby passengers can still fasten their belts correctly.
Also inspect visibility from the driver's position, storage for everyday items and access to important controls. A longer feature list is less valuable if the driver finds routine tasks difficult or the family cannot sit comfortably for its normal journeys.
Compare purchase and ownership costs fairly
Request itemised on-road quotations for the same registration city and date. Record fuel, gearbox, equipment grade and model year. Keep insurance cover comparable and ask which accessories or protection products are optional rather than accepting one unexplained total.
| Cost or practical check | What to obtain |
|---|---|
| Purchase | Written vehicle, tax and registration breakdown |
| Insurance | Matching cover, insured value and deductibles |
| Finance | Rate, fees, tenure and total repayment |
| Maintenance | Schedule and local workshop estimate |
| Delivery | Date, stock details and booking conditions |
| Long-term planning | Your own distance and fuel-cost assumptions |
Check the workshop you will actually use for each brand. Distance, appointment availability and access during your working hours matter. Avoid treating nationwide reputation as proof that your nearest branch will suit your requirements.
Resale values depend on condition, kilometres, demand and service records. Do not treat a prediction as guaranteed savings.
Questions about Nexon and Brezza
Which one should a diesel buyer consider
The current Nexon offers diesel manual and AMT combinations. The announced updated Brezza range contains petrol and CNG, not diesel. Confirm that your journey pattern and local rules suit diesel before choosing it.
Does the new Brezza still use the old CNG arrangement
The July 2026 manufacturer announcement identifies an underbody tank arrangement. Inspect the actual quoted vehicle and load your luggage rather than relying on a review of the earlier installation.
Is every Nexon automatic the same
No. The range lists different AMT and DCT combinations. Test and quote the exact gearbox you intend to purchase; another variant's drive does not answer the same question.
Is either SUV guaranteed safer in every accident
No. Assessment results apply to defined test conditions and vehicle coverage. Correct restraints, tyres, maintenance and responsible driving still matter. Compare the actual records rather than relying only on stars.
Which is cheaper to own
That depends on the exact purchase price, fuel, distance, insurance, finance and maintenance. Build a calculation with your own inputs instead of assuming a universal cost advantage from the badge.
Compare two exact variants before paying
Choose your required fuel and gearbox first, then test one suitable Nexon and Brezza. Bring passengers and luggage, check the current safety record and obtain itemised quotations. Book only after the specification, local support and total budget are clear.
