5 Best CNG Mid-Size SUVs Under ₹20 Lakh in India

Factory CNG is common on hatchbacks and sub-4 metre compact SUVs, but it thins out fast once you move up to mid-size SUVs. Only two models, the Maruti Victoris and Grand Vitara, currently sell one off the showroom floor with a factory kit; a third, the Toyota Hyryder, shares that setup under a different badge. A fourth, the Tata Curvv, has been widely reported but not officially confirmed, and a fifth way to get CNG in this size bracket exists only through the aftermarket. This list runs through all five, exactly as they stand today, so you know which are buyable now and which aren't.

Key takeaways

• Maruti Victoris: the cheapest of the on-sale options at ₹11.55 lakh, and the only one whose CNG tank sits under the floor instead of eating into the boot.
• Maruti Grand Vitara: ₹1.45 lakh pricier than the Victoris, adding cruise control and a reverse camera, though CNG is offered only on the Delta trim, which skips the ventilated seats and 9-inch touchscreen of the petrol Zeta.
• Tata Curvv: not officially announced as a CNG model, though pre-launch reports point to a turbocharged engine that would be the most powerful of the factory CNG options here.
• Toyota Hyryder: runs the same engine and platform as the Grand Vitara, but costs more for less boot space at its equivalent CNG trim.
• Mahindra Scorpio N: the only way to get CNG in a full-size body here, but only through a dealer-fitted retrofit kit, since Mahindra doesn't offer one from the factory.

What does a mid-size SUV mean?

A mid-size or C-segment SUV in India typically runs 4.3 to 4.4 metres in length, longer than the sub-4 metre compact SUVs like the Fronx or Brezza (covered separately in our compact SUV CNG list), but shorter than a full-size SUV like the Scorpio N.

That extra length usually pushes prices past ₹10 lakh even before CNG is added, which is part of why CNG uptake in this bracket has been slow. Manufacturers have prioritised the higher-volume compact SUV and hatchback segments first. The Grand Vitara, Victoris and Hyryder sit squarely in this bracket; the Curvv is marketed as a coupe SUV but competes directly with them on size and price, which is why it's included here despite the unconventional body shape.

How we shortlisted these cars

• Mid-size/C-segment SUV body style: sub-4m compact SUVs are excluded, even ones with CNG, since they're covered in a separate list.
• Every real option, not just factory ones: this segment has too few factory CNG cars to build a meaningful list on that criterion alone, so one reported upcoming launch (Curvv) and one aftermarket retrofit (Scorpio N) are included, both clearly labelled as such.
• Under ₹20 lakh: applied to the CNG variant's price where it exists, or the expected/estimated price where it doesn't yet.

1. Maruti Victoris

• Pricing: ₹11.55 lakh
• Fitting: Factory fitted CNG with an underbody tank

Among the two Maruti cars on this list, the Victoris is the newer and cheaper one, and it's built around a genuinely different approach to fitting CNG. The tank sits under the floor rather than in the boot. This is the LXi CNG, the entry-level trim, and it holds onto a reasonably strong kit list at that price point rather than stripping down to bare essentials the way some cheaper compact SUVs do. Against the Grand Vitara, its closest sibling on this list, it undercuts on price by about ₹1.45 lakh.

Features:

• 7 inch touchscreen with wireless Android Auto and Apple CarPlay

• Automatic climate control with rear AC vents

• Air purifier

• Keyless entry with push-button start

• 6 airbags, ABS with EBD, ESC, traction control, and hill-hold assist

• 60:40 split-foldable rear seat

• Engine: 87 bhp, 121.5 Nm.

• Mileage: 27.02 km/kg, the best of the three on-sale factory options.

• Boot space: Not published by Maruti for either the petrol or CNG variant. The underbody CNG tank is stated to leave boot capacity uncompromised, but no litre figure has been released to confirm this.

• Transmission: 5-speed manual only.

• Warranty: 3 years/100,000 km standard, extendable up to 6 years/160,000 km.

2. Maruti Grand Vitara

• Pricing: ₹13.00 lakh
• Fitting: Factory fitted CNG

The Grand Vitara's CNG version disappeared from sale for a stretch before Maruti brought it back in May 2026 on the Delta trim. CNG is offered only on that mid-rung Delta trim, so it's a step up from the Victoris LXi CNG on cruise control and a reverse camera, but the ventilated seats, 9-inch touchscreen and wireless charging stay on the pricier petrol Zeta.

Features:

• 7-inch touchscreen with Android Auto and Apple CarPlay

• Cruise control

• Automatic climate control with rear AC vents

• Clarion audio system

• 6 airbags, ESC, hill hold assist, ABS with EBD, reverse parking camera

• Engine: 88 PS, 121.5 Nm.

• Mileage: 26.6 km/kg.

• Boot space: 373 litres on petrol. A CNG-specific figure hasn't been published.

• Transmission: 5-speed manual only.

• Warranty: 3 years/100,000 km standard, extendable up to 6 years/160,000 km.

3. Tata Curvv

• Pricing: Not announced; pre-launch reports point to ₹11-13 lakh
• Fitting: Factory fitted CNG, reported but not officially announced (spy shots confirm testing, and the car isn't on sale)

The Curvv is a different shape from the rest of this list. Tata markets it as a coupe-SUV rather than a conventional boxy SUV, but it competes on size and price with the Grand Vitara and Hyryder, which is the reason it's here at all. Tata hasn't officially announced a CNG version, and Autocar India reports it is under active consideration; pre-launch reports point to a Diwali 2026 window and the same twin-cylinder tank approach as the Nexon iCNG, but nothing about it is final until it actually launches. Treat every figure below as a placeholder, not a specification.

Expected features (unconfirmed until launch):

• Turbocharged 1.2 litre petrol engine tuned for CNG

• Twin cylinder CNG tank, similar in concept to the Nexon iCNG

• 6-speed manual gearbox

• Engine: Around 99 bhp and 170 Nm, per pre-launch reports, close to the Nexon's CNG output. Unconfirmed.

• Mileage: Not announced.

• Boot space: Not announced.

• Transmission: 6-speed manual, expected.

• Warranty: Not announced; would follow Tata's standard new-car warranty terms once launched.

4. Toyota Hyryder

• Pricing: ₹13.71 lakh
• Fitting: Factory fitted CNG

Toyota builds the Hyryder alongside Maruti on the same production line as the Grand Vitara, and the CNG version reflects that: same 1.5 litre engine, same power and torque figures, same manual-only gearbox. This is the S CNG, and it gets standard cruise control, which the Victoris LXi CNG does without, though the Grand Vitara's Delta CNG has it too. Where it falls behind is boot space, at 273 litres against the Grand Vitara's 373-litre petrol figure, though neither number is CNG-specific for either car.

Features:

• 7-inch touchscreen with Apple CarPlay and Android Auto

• Cruise control

• Automatic climate control

• Height adjustable driver seat and air purifier

• 6 airbags, ABS, ESC, keyless entry with push button start

• Rear parking camera and rear AC vents

• Engine: 86.63 bhp @ 5500 rpm, 121.5 Nm @ 4200 rpm, effectively the same tune as the Grand Vitara's.

• Mileage: 26.6 km/kg.

• Boot space: 273 litres.

• Transmission: 5-speed manual only.

• Warranty: 3 years/100,000 km standard, extendable through Toyota's extended warranty programme.

5. Mahindra Scorpio N

• Pricing: ₹15.57 lakh (Z4 petrol) plus roughly ₹1.05-1.35 lakh for a retrofit CNG kit
• Fitting: Retrofit only. Mahindra does not sell the Scorpio N with factory CNG; every CNG Scorpio N on the road today has been converted after purchase by a dealer or workshop.

The Scorpio N is a full-size body-on-frame SUV, a size class above everything else on this list, and it's here to answer a different question: what if you want CNG running costs on something considerably bigger than a mid-size SUV? The catch is that Mahindra doesn't build one that way. The car's turbo petrol engine uses direct injection, which needs a more expensive specialised CNG kit than the port-injected engines most retrofit shops handle, and installation runs 6 to 8 hours with custom fabrication for the cylinder mounts.

What a retrofit kit typically includes:

• A dedicated direct-injection-compatible CNG kit (standard port-injection kits aren't compatible with this engine)

• A 60-90 litre CNG cylinder, depending on the kit chosen

• RTO paperwork and registration updates as part of the installation cost

• Engine: 200 bhp on petrol (2.0-litre turbo-petrol); CNG-mode power and torque figures aren't disclosed by any kit installer.

• Mileage: 13-15 km/kg in the city and 20-21 km/kg on the highway, by workshop estimates, not an ARAI certified figure.

• Boot space: Not disclosed; the retrofit cylinder is mounted in the boot, so cargo space is reduced by an amount that varies by installer and cylinder size.

• Transmission: 6-speed manual, unchanged from the petrol car; the CNG kit doesn't affect the gearbox.

• Warranty: The vehicle keeps Mahindra's standard warranty on the parts the kit doesn't touch, but the CNG kit itself is warrantied separately by the installer, not by Mahindra.

Conclusion

The honest picture of CNG in the mid-size SUV segment is that it's still a two-car category. The Victoris and Grand Vitara are the only factory options, with a same-platform Toyota badge twin as a third that costs more for less. A fourth, the Curvv, has been reported but not officially announced. A fifth path exists only if you're willing to have a much bigger, more powerful SUV converted after the fact rather than buying CNG off the showroom floor. If you want CNG in this size class today, the Victoris is the value pick, the Grand Vitara adds cruise control and a reverse camera for about ₹1.45 lakh more, and everything else on this list comes with a catch of some kind.

FAQs

Which mid-size SUVs currently sell with factory fitted CNG in India?

Only two: the Maruti Victoris and the Maruti Grand Vitara. The Toyota Hyryder is mechanically the same car as the Grand Vitara and also has factory CNG, so it's really three badges on two underlying platforms.

Is the Tata Curvv CNG available to buy yet?

No, and Tata hasn't officially confirmed one either. Autocar India reports the CNG version is under active consideration, with pre-launch reports pointing to a Diwali 2026 window, so no price or specification is official yet.

Can I get a Mahindra Scorpio N with CNG?

Not from Mahindra directly. Aftermarket workshops offer a direct-injection-compatible retrofit kit, but it's not a factory option, and mileage and running-cost figures for it are workshop estimates rather than ARAI-certified numbers.

Which is the cheapest CNG mid-size SUV you can actually buy today?

The Maruti Victoris, at ₹11.55 lakh ex-showroom for the LXi CNG variant.
