The Indian midsize SUV segment has become more complicated — and arguably more interesting — with the arrival of the Tata Curvv Series X.
Launched at a starting price of ₹9.99 lakh (ex-showroom), the revised Curvv doesn't merely get new variant names. Tata has simplified the line-up, moved several desirable features further down the range and attempted to address one of the original Curvv's key weaknesses by improving rear-seat packaging.
That puts the Curvv Series X directly into a fiercely contested market populated by the Hyundai Creta, Kia Seltos, Citroën BasaltX, Tata Sierra and Maruti Suzuki Grand Vitara.
But these six SUVs take very different routes to the same ₹10-20 lakh customer.
The Creta remains the established all-rounder. The Seltos concentrates heavily on technology and performance. The BasaltX offers coupé-SUV styling at a noticeably lower price. The Sierra majors on space, road presence and premium positioning. Grand Vitara brings strong-hybrid efficiency and even AWD into the equation. And the updated Curvv Series X attempts to combine distinctive styling, competitive pricing and a particularly wide petrol-diesel choice.
So, which one makes the most sense in 2026?
Price Comparison: Curvv Series X Starts Aggressively
SUV | Starting Price | Top Price* |
Citroën BasaltX | ₹8.55 lakh | ₹14.11 lakh |
Tata Curvv Series X | ₹9.99 lakh | ₹18.99 lakh |
Maruti Suzuki Grand Vitara | ₹10.77 lakh | ₹19.62 lakh |
Hyundai Creta | ₹10.90 lakh approx. | Around ₹20 lakh |
Kia Seltos | ₹10.99 lakh | ₹19.99 lakh |
Tata Sierra | ₹11.49 lakh | ₹21.29 lakh |
*Ex-showroom; prices vary by engine, transmission, special edition and colour combination.
The first takeaway is obvious: BasaltX remains the price disruptor. Its range begins below all five rivals, while even its highest turbo-automatic versions remain significantly below the most expensive versions of the Creta, Seltos, Sierra and Curvv.
The more important development, however, is the Curvv Series X's ₹9.99 lakh positioning. It now undercuts the mainstream entry points of the Creta and Seltos while still offering Tata's more distinctive coupé-SUV design.
Grand Vitara begins at roughly ₹10.77 lakh and reaches ₹19.62 lakh after its August 2026 price revision. The Sierra occupies a somewhat more premium position and extends all the way to ₹21.29 lakh.
Tata Curvv Series X Variant-Wise Prices
The revised Curvv line-up has been reduced to six principal personas: Smart X, Pure X, Pure X+, Creative X+, Accomplished X and Accomplished X+.

Accomplished X+ #Dark | – | – | ₹18.75L | – | ₹18.99L |
The major structural change is that the more powerful Hyperion direct-injection turbo-petrol is now concentrated at the top end and is automatic-only. Tata has also reduced the automatic premium on several lower variants to around ₹1.30 lakh.
Kia Seltos Variant-Wise Price Structure
The current-generation Seltos offers one of the widest engine-transmission matrices in this comparison.
Variant | 1.5 Petrol MT | Petrol IVT | Turbo Petrol iMT | Turbo DCT | Diesel MT | Diesel AT |
HTE | ₹10.99L | – | – | – | ₹12.59L | – |
HTE(O) | ₹12.09L | ₹13.39L | ₹12.89L | – | ₹13.69L | ₹14.99L |
HTK | ₹13.09L | ₹14.39L | ₹13.89L | – | ₹14.69L | ₹15.99L |
HTK(O) | ₹14.19L | ₹15.49L | ₹14.99L | ₹16.29L | ₹15.79L | ₹17.09L |
HTX | ₹15.59L | ₹16.89L | – | ₹17.69L | ₹17.19L | ₹18.49L |
HTX(A) | ₹16.69L | ₹17.99L | – | ₹18.79L | ₹18.29L | ₹19.59L |

GTX(A) / X-Line(A) | – | ₹19.49L | – | ₹19.99L | – | ₹19.99L |
The Seltos range therefore remains particularly strong for buyers who want to choose the engine first and equipment level second.

Accomplished+ | – | – | ₹20.99L | ₹20.29L | ₹21.29L |
The Sierra is clearly positioned above the Curvv at the upper end, but the overlap through the ₹13-19 lakh zone makes the two Tata SUVs natural internal rivals.

Dimensions: Which SUV Is Biggest?
Model | Length | Width | Height | Wheelbase |
Kia Seltos | 4,460 mm | 1,830 mm | 1,635 mm | 2,690 mm |
Citroën BasaltX | 4,352 mm | 1,765 mm | 1,593 mm | 2,651 mm |
Maruti Grand Vitara | 4,345 mm | 1,795 mm | 1,645 mm | – |
Tata Sierra | 4,340 mm | 1,841 mm | 1,715 mm | 2,730 mm |
Hyundai Creta | 4,330 mm | 1,790 mm | 1,635 mm | 2,610 mm |
Tata Curvv Series X | ~4,308 mm | ~1,810 mm | ~1,630 mm | ~2,560 mm |
The Seltos is the longest SUV here, while the Sierra has the widest body and the longest wheelbase.
That helps explain why the Sierra feels like the more conventional, upright family SUV compared with the lower-roofed Curvv.
The BasaltX and Curvv, meanwhile, sacrifice some upright SUV proportions in exchange for their sloping coupé-style rooflines.
Engine Comparison
This is where the six SUVs become dramatically different.
Naturally Aspirated Petrol
SUV | Engine | Power | Torque |
Creta | 1.5L Petrol | 115hp | 144Nm |
Seltos | 1.5L Petrol | ~115hp | ~144Nm |
Sierra | 1.5L Petrol | 106PS | 145Nm |
Grand Vitara | 1.5L Petrol Mild Hybrid | ~103PS | ~137Nm |
BasaltX | 1.2L Petrol | 82PS | 115Nm |
For relaxed city use, the naturally aspirated engines remain adequate, but they are not the performance choices of this group.
Turbo Petrol
SUV | Engine | Power | Torque |
Creta | 1.5L Turbo | 160hp | 253Nm |
Seltos | 1.5L Turbo | 160PS | 253Nm |
Sierra | 1.5L Turbo | 160PS | 255Nm |
Curvv Hyperion | 1.2L T-GDI | ~125PS | 225Nm |
Curvv Revotron | 1.2L Turbo | ~120PS | 170Nm |
BasaltX | 1.2L Turbo | 110PS | 190/205Nm |
For outright performance, Seltos, Creta and Sierra sit in another league, with their 160PS-class turbo engines.
The Curvv Hyperion sits between those high-output engines and the Basalt's 110PS turbo.
Diesel: Curvv Has a Unique DCT Proposition
The Creta, Seltos, Sierra and Curvv remain attractive to high-mileage buyers because they continue to offer diesel power.
Creta's 1.5-litre diesel produces around 116hp and 250Nm, while the Sierra's 1.5-litre diesel produces 118PS and up to 280Nm with the automatic.
The Curvv differentiates itself by pairing its diesel with a dual-clutch automatic, whereas Creta, Seltos and Sierra use torque-converter automatics for their diesel variants.
For enthusiasts, the Curvv diesel-DCT remains an unusual combination in the Indian market.
Grand Vitara's Big Advantage: Strong Hybrid
Grand Vitara cannot match the turbo-petrol performance of a Seltos, Creta or Sierra.
Instead, it plays a completely different game.
Its strong-hybrid system can operate in electric mode under suitable conditions and delivers significantly higher claimed fuel efficiency than conventional petrol rivals.
Depending on specification, claimed Grand Vitara fuel economy extends to around 27.97km/l, making it the most obvious choice here for buyers prioritising fuel consumption in heavy urban use.
It also remains the only SUV among these six to offer an AWD option.
BasaltX: Cheapest SUV, But Not a Bare-Bones Proposition
The Citroën starts significantly below its competitors, but the higher BasaltX versions now include equipment such as:
10.25-inch infotainment
digital driver's display
ventilated front seats
wireless charging
360-degree camera
six airbags
ESP
TPMS
cruise control
upgraded cabin materials
Its 1.2-litre turbo produces 110PS, with 190Nm in manual form and 205Nm with the 6-speed automatic.
Fuel-efficiency claims stand at 19.5km/l for the turbo manual and 18.7km/l for the turbo automatic.
The BasaltX therefore isn't attempting to beat a top Seltos or Sierra feature-for-feature. Its strength is delivering a stylish coupé-SUV package at substantially less money.
Curvv Series X: What Has Actually Improved?
Tata's Series X exercise matters because the company has focused on the middle of the range rather than simply adding another expensive flagship.
Pure X onwards now gains more equipment, while variants such as Pure X+ and Creative X+ significantly improve the value equation.
Depending on variant, equipment includes:
10.25-inch touchscreen
wireless Android Auto and Apple CarPlay
automatic climate control
cruise control
panoramic sunroof
360-degree camera
ventilated front seats
powered driver's seat
12.3-inch touchscreen
JBL audio
Level 2 ADAS
Tata has also revised the seating package. Slimmer front seatbacks and changes to the positioning of the rear bench are intended to improve rear-passenger space and comfort — an important update given that rear-seat packaging was one of the compromises associated with the Curvv's coupé form.
Curvv vs Creta: Which Is Better?
For buyers wanting a safe all-round choice, Creta remains extremely difficult to dismiss.
It combines:
three engines
petrol and diesel automatic choices
strong feature content
panoramic sunroof
ventilated seats
dual-zone climate control
twin-screen cockpit
Bose audio
connected-car features
Level 2 ADAS
Six airbags, ESC, TPMS and other core safety systems are widely available across the range.
The Curvv's advantages are its more distinctive design, lower entry point and diesel-DCT option.
Verdict: Creta for the conventional all-round family buyer; Curvv if design and differentiation matter more.
Curvv vs Seltos: Performance or Style?
The Seltos has become one of the strongest alternatives to the Creta.
The latest generation measures 4,460mm long with a 2,690mm wheelbase, making it considerably longer than the Creta and Curvv.
Its engine portfolio is also exceptionally broad:
1.5 petrol MT/IVT
1.5 turbo-petrol manual/iMT and DCT
1.5 diesel MT/AT
The 160PS turbo-petrol gives it a decisive performance advantage over the Curvv's regular 1.2 turbo.
Verdict: Seltos for performance and technology; Curvv for coupé styling and potentially stronger value in equivalent mid variants.
Curvv vs Sierra: The Most Interesting Tata-vs-Tata Battle
This may actually be the most important comparison for Tata.
The Curvv starts at ₹9.99 lakh.
The Sierra starts at ₹11.49 lakh.
At the top, Curvv reaches ₹18.99 lakh while Sierra stretches to ₹21.29 lakh.
So the question becomes:
Should a buyer considering a high-spec Curvv simply move up to a Sierra?
The Sierra has a 2,730mm wheelbase, 205mm ground clearance and a more upright body. It also offers a 160PS turbo-petrol and diesel automatic with up to 280Nm.
Curvv fights back with its lower pricing, coupé styling and arguably more striking road presence.
Verdict: Below roughly ₹16 lakh, Curvv remains compelling. As the budget approaches ₹18-20 lakh, Sierra becomes increasingly difficult to ignore.
Curvv vs Grand Vitara: Diesel vs Hybrid
These two target very different buyers.
Curvv gives you:
turbo petrol
more powerful T-GDI turbo petrol
diesel
DCT choices
Grand Vitara gives you:
mild hybrid
strong hybrid
CNG
AWD
If your monthly running is high but largely urban, Grand Vitara strong hybrid has an obvious efficiency advantage.
If much of that high mileage takes place on highways, the Curvv diesel becomes a far more interesting proposition.
Verdict: Grand Vitara for urban fuel economy; Curvv diesel for highway-heavy usage.
BasaltX vs Curvv: The Real Coupe-SUV Showdown
These are the two closest rivals conceptually.
Both use coupé-inspired SUV styling, but they approach pricing very differently.
BasaltX begins around ₹8.55 lakh while Curvv Series X begins at ₹9.99 lakh.
The Citroën turbo offers 110PS, compared with substantially higher output from the Curvv's turbo engines.
Curvv also offers diesel, a DCT, ADAS and a more extensive premium-feature portfolio.
BasaltX counters by offering strong ride comfort, a 470-litre boot and dramatically lower purchase prices.
Verdict: BasaltX wins on affordability; Curvv offers a more complete premium SUV experience.
Which Is Best for Features?
Kia Seltos
Arguably the strongest if features and cabin technology are at the top of your shopping list.
Hyundai Creta
Closely follows the Seltos and packages its technology within a proven family-SUV formula.
Tata Sierra
Feels the most premium and spacious among these six, particularly in higher variants.
Tata Curvv Series X
Series X improves the equipment-to-price ratio dramatically in its mid variants.
Grand Vitara
Has the essentials plus some premium features, but its main selling proposition is efficiency rather than gadget count.
BasaltX
Much better equipped than its price suggests, but cannot match the feature depth of ₹18-20 lakh versions of the Korean and Tata SUVs.
Which Is Best for Performance?
Winner: Kia Seltos / Hyundai Creta / Tata Sierra
All three offer approximately 160PS turbo-petrol options.
The Seltos and Creta's 1.5 turbo-DCT combinations are particularly attractive to buyers seeking strong acceleration.
Sierra's 160PS/255Nm turbo is similarly powerful and gives the Tata a surprisingly strong performance proposition.
Which Is Best for Mileage?
Winner: Maruti Suzuki Grand Vitara Strong Hybrid
With claimed economy approaching 28km/l in its strong-hybrid form, no conventional petrol competitor here can realistically match the Grand Vitara's headline efficiency.
Which Is Best for Highway Running?
Curvv Diesel / Creta Diesel / Seltos Diesel / Sierra Diesel
Diesel continues to make sense for high annual mileage.
Curvv's DCT makes it particularly interesting, while Creta and Seltos offer proven diesel-automatic packages.
Sierra has the torque advantage on paper in automatic form.
Which Is Best for Road Presence?
Winner: Tata Sierra
Sierra's upright proportions, 1,841mm width and 2,730mm wheelbase give it a much more substantial stance than the conventional midsize-SUV template.
For buyers wanting something more dramatic rather than simply large, however, Curvv's coupé silhouette remains distinctive.
Which Is Best Under ₹12 Lakh?
Tata Curvv Series X Pure X / Pure X+
Citroën BasaltX
Grand Vitara Sigma
Creta lower variants
Seltos HTE
At this price point, Curvv Series X becomes particularly strong.
Pure X starts at around ₹10.99 lakh while Pure X+ is ₹11.79 lakh, giving buyers a significantly better-equipped vehicle without having to move to ₹14-15 lakh territory.
BasaltX remains the absolute value choice.
Which Is Best Around ₹15 Lakh?
This is perhaps the real battleground.
At approximately ₹15 lakh, buyers can access meaningful versions of:
Curvv Creative X+/Accomplished X
Creta S(O)/SX territory
Seltos HTK(O)/HTX territory
Sierra Pure/Pure+ territory
Grand Vitara Zeta/Alpha territory
top-end BasaltX variants
This is where buying priorities become more important than outright specifications.
Want performance? Seltos.
Want the safe family choice? Creta.
Want style? Curvv.
Want space and SUV road presence? Sierra.
Want efficiency? Grand Vitara.
Want maximum car for minimum purchase price? BasaltX.
Final Verdict: Which Midsize SUV Should You Buy?
There isn't one outright winner because these six products now represent six distinct interpretations of the Indian midsize SUV.
Buy the Tata Curvv Series X if:
You want coupé styling, a broad petrol/diesel range, strong mid-variant value and something less conventional than the Creta-Seltos formula.
Buy the Hyundai Creta if:
You want the safest all-round choice with a balanced combination of comfort, features, engines, refinement and family usability.
Buy the Kia Seltos if:
You prioritise performance, cabin technology, equipment and multiple engine-transmission combinations.
Buy the Citroën BasaltX if:
Your priority is value. It delivers distinctive styling and strong comfort at prices where many rivals are only getting started.
Buy the Tata Sierra if:
You want a larger-feeling, more upright and premium SUV and are willing to stretch the budget beyond the Curvv.
Buy the Maruti Suzuki Grand Vitara if:
Fuel economy, strong-hybrid technology, CNG or AWD matter more than outright turbocharged performance.
Auto Punditz Take
The launch of the Curvv Series X is less about Tata reinventing the Curvv and more about correcting its positioning.
At ₹9.99 lakh, the headline price is useful, but the bigger story lies in the Pure X, Pure X+ and Creative X+ variants. Tata has pushed important comfort and technology features lower down the range while simplifying an increasingly complicated variant structure.
That makes the Curvv substantially more competitive against the Creta and Seltos.
But the market has also moved since the original Curvv arrived.
The Sierra now gives Tata buyers another compelling midsize SUV within the same showroom. Kia's latest Seltos has grown larger and remains formidable on performance and features. Creta continues to be an exceptionally complete family product. Grand Vitara has established a distinct niche around hybrid efficiency, while
BasaltX challenges the entire group on acquisition cost.
The result is that the Indian midsize SUV buyer no longer needs to ask simply, “Which SUV is best?”
The more relevant question is: what matters most — price, performance, fuel efficiency, space, technology or design?
For buyers spending around ₹12-16 lakh, the new Curvv Series X may now be at its strongest.
Move towards ₹18-20 lakh, however, and the decision becomes much harder. At that price, the 160PS Seltos and Creta turbo variants, Grand Vitara Hybrid and the larger
Tata Sierra all begin making compelling arguments of their own.
That is exactly why the Curvv Series X update matters: it doesn't necessarily make the Curvv the segment winner, but it puts the SUV firmly back into the shortlist.
