Points To Check out for Hyundai CRETA Converted to CNG

The Hyundai CRETA has been one of the most successful SUVs in the Indian market. With its bold styling, comfort, and feature-rich interiors, it remains a favorite choice among urban and semi-urban buyers. But with rising fuel prices and a growing interest in cleaner and more affordable alternatives, a common question arises:

👉 Can the 2021 model Hyundai CRETA be converted to CNG?

This blog explores the possibilities, benefits, challenges, and legal aspects of converting the 2021 Hyundai CRETA to a Compressed Natural Gas (CNG) system.

Hyundai CRETA 2021 Model

The 2021 Hyundai CRETA is available in petrol and diesel engine variants, with multiple trims. The petrol engine is a 1.5L MPi motor that’s suitable for city and highway drives. However, Hyundai does not offer a factory-fitted CNG variant for the CRETA as of now.

So, if you’re considering a CNG conversion, it must be done through an aftermarket CNG installation, which brings us to our next topic.

Aftermarket CNG Conversion Kits

A CNG conversion kit is a set of components installed in petrol cars to allow them to run on compressed natural gas in addition to petrol. These kits typically include:

CNG Cylinder
Pressure regulator
Injector rail
Emulator & switch
Piping and safety valves

There are two types of kits available:

Venturi CNG Kits – simpler and cheaper, but suitable only for older carburetor engines.
Sequential CNG Kits – advanced and compatible with fuel-injected engines like the one in the 2021 CRETA.

✅ The Hyundai CRETA 1.5L petrol engine is compatible only with sequential CNG kits.

Government Rules & RTO Approval

In India, it’s legal to install an aftermarket CNG kit, but it must be approved by the RTO (Regional Transport Office). The process includes:

Installation at a government-approved CNG center.
Endorsement on the Registration Certificate (RC).
Vehicle fitness test (in some states).
Valid insurance reflecting dual-fuel usage.

🚫 Note: Installing an unapproved CNG kit may void your car insurance and attract fines.

Cost of Conversion

The cost of installing a sequential CNG kit in a car like the CRETA ranges from ₹50,000 to ₹70,000, depending on:

Brand (Lovato, BRC, Tomasetto, etc.)
Cylinder size (12kg or 14kg)
Installer reputation

While the initial cost may seem high, CNG costs ₹70–75/kg (as of 2025), compared to ₹100+ per litre for petrol, leading to major long-term savings.

Impact on Performance

One of the biggest concerns with CNG conversion is performance drop. Here’s what to expect on your 2021 Hyundai CRETA:

Feature	Petrol Mode	CNG Mode
Power Output	115 PS	~100 PS (approx.)
Torque	144 Nm	Slightly reduced
Pickup & Acceleration	Better	Slower response
Top Speed	Unchanged	Slightly lower
Engine Wear	Higher on CNG	Needs timely service

While city driving won’t feel too different, highway overtaking may feel slower on CNG. Regular servicing, spark plug checks, and CNG filter replacements are necessary to maintain smooth operation.

Warranty Concerns ( Hyundai India)

One critical point:
If you install an aftermarket CNG kit, Hyundai may void the engine and fuel system warranty.

Most manufacturers only honor the warranty if the CNG kit is:

Installed by a Hyundai-authorized partner (rare)
Approved and certified by the government

So, if your 2021 Hyundai CRETA is still under warranty, consider the implications carefully before conversion.

Fuel Efficiency Comparison

The good news:
CNG offers excellent fuel economy for city use.

Fuel Type	Approx. Mileage
Petrol	15–17 km/l
CNG	22–25 km/kg

With a full 12kg cylinder, you can expect 250–300 km per refill, costing less than ₹800 — nearly 40–50% savings over petrol.

Is CNG Safe for SUVs Like CRETA?

Yes, provided:

The installation is done by an experienced professional.
Certified components are used.
Regular safety inspections are conducted.

Modern CNG kits come with automatic shutoff valves, sensors, and leak detectors to ensure safety. However, CNG tanks reduce boot space, which is a key consideration for SUV owners.

Final Verdict: Should You Convert?

Yes, the 2021 Hyundai CRETA can be converted to CNG using a sequential kit from a certified installer. However, this decision must factor in:

Whether your car is still under warranty
Your daily running distance
Your access to CNG fuel stations
Legal compliance

If your daily commute exceeds 40–50 km and you want to reduce fuel costs significantly, CNG is a smart move.

Just ensure it’s done professionally, legally, and safely.
