In this comparison, we’ll highlight one of the most important factors for potential owners: mileage. We’ll present the official ARAI mileage figures for both petrol and CNG variants, as well as consider real-world performance. 

By the end, you’ll have a clear understanding of which Aura variant offers the best combination of lower running costs and everyday usability. Read further to explore the Hyundai Aura Petrol vs CNG mileage comparison in detail.

Hyundai Aura ARAI Mileage Figures

Official ARAI-certified mileage for the Aura across all engine and transmission options is:

Hyundai Aura Real-World Mileage vs ARAI Mileage

Though ARAI mileage figures are recorded under ideal test conditions, real-world driving tells a different story. In daily city use, the Hyundai Aura petrol manual achieves a fuel efficiency of around 19.7 kmpl. The CNG version, on the other hand, returns approximately 25.12 km/kg in city driving, exceeding its certified figure.

Several factors contribute to the difference between ARAI and actual mileage:

1. Driving Style: Rapid acceleration and frequent braking negatively impact fuel economy.
2. Traffic Flow: Congested city traffic reduces mileage compared to smoother highway runs.
3. Load & Air-Conditioner Usage: Extra passengers or heavy AC usage increase fuel consumption.
4. Maintenance: Timely servicing, clean filters, and proper tyre pressure help maintain efficiency.

For most buyers, the Hyundai Aura offers reliable real-world fuel economy, with the CNG variant proving to be the most cost-effective choice for those who drive regularly.

Hyundai Aura Fuel Efficiency Comparison: Petrol vs CNG

In terms of fuel economy, the Hyundai Aura’s petrol and CNG variants cater to different user needs. The petrol version offers a balance between power and fuel consumption, delivering an ARAI-claimed mileage of around 17 kmpl. 

On the other hand, the CNG variant, with its factory-fitted setup, is designed to maximise fuel cost savings, offering an ARAI-certified mileage of about 22 km/kg, making it more economical for high-mileage drivers. Under real-world driving conditions, particularly in city traffic, the two models exhibit distinct differences. 

While the petrol variant maintains consistent performance, the CNG variant’s efficiency can be influenced by factors such as driving habits and traffic conditions. Therefore, it’s essential to consider individual driving patterns when choosing between the two variants.

Hyundai Aura City Fuel Efficiency Comparison

City driving for the Hyundai Aura petrol variants generally offers satisfactory fuel efficiency, but fuel consumption increases due to frequent halts and starts. Automatic petrol versions are slightly less efficient than manual ones because of the torque converter. 

The CNG model, however, stands out as the more economical choice for daily urban commutes, especially in heavy traffic. The main factors for the difference are:

1. Fuel Characteristics: CNG delivers cleaner and more efficient combustion at lower speeds, resulting in improved mileage in stop-and-go traffic. It is highly suitable for city drives with frequent congestion.
2. Engine Calibration: The CNG variant’s tuning is designed to optimise fuel consumption during slow-moving traffic, keeping the engine at lower revs and enhancing mileage.
3. Traffic Conditions: Petrol engines require more fuel for sudden acceleration in crowded traffic, while CNG engines operate more efficiently in steady, slow traffic.
4. Idle Efficiency Time: CNG engines use less fuel when idling in traffic compared to petrol engines, resulting in superior mileage in city conditions.
5. Thermal Control: Petrol engines tend to heat more in constant stop-and-go conditions, which lowers their efficiency. In contrast, CNG engines maintain stable running temperatures, thereby improving overall fuel economy.

Hyundai Aura Highway Fuel Efficiency Comparison

On the highway, Hyundai Aura petrol models generally deliver better mileage with smooth cruising and controlled braking. Petrol manual variants usually return higher fuel efficiency than automatic ones because of direct power transfer. The CNG version offers good highway economy but may feel slightly less powerful during overtaking due to lower engine output.

The factors affecting highway mileage differences include:

1. Cruising Efficiency: Petrol engines perform more efficiently at higher speeds, while CNG remains more economical per kilometre, making it cost-effective for long-distance drives.
2. Load and Air-Conditioning Consumption: Mileage for both petrol and CNG decreases when the car is fully loaded or when the AC is used heavily, with a greater drop seen in the CNG variant.
3. Driving Habits: Smooth acceleration and maintaining steady speeds are essential for maximising fuel economy in both petrol and CNG versions. Sudden acceleration or hard braking reduces efficiency.
4. Altitude and Terrain: Driving in hilly or uneven terrain affects fuel consumption, with petrol engines generally managing gradients more effectively due to their higher power delivery.
5. Fuel Availability and Refuelling Stops: Long trips require planning fuel stops, especially for CNG, since limited refuelling points can impact travel convenience and indirectly affect mileage.

Hyundai Aura Fuel Cost Comparison: Petrol vs CNG

Understanding fuel costs is essential when deciding between the Hyundai Aura petrol and CNG variants. We’ll compare the running expenses for an average monthly distance of 1,500 km, along with key factors, to find out which option is more economical.

Note: Fuel expense is estimated using the average petrol price of ₹94.77/litre and the CNG price of ₹76/kg. Actual fuel costs may vary depending on your location and changes in fuel prices. The Hyundai Aura CNG variant offers significantly lower running costs, making it a more economical choice for drivers who cover long distances.

Hyundai Aura Mileage vs Competitors

Comparing the Hyundai Aura’s mileage with that of its main rivals provides a better insight into its fuel efficiency. Listed below are the official mileage ratings for both petrol and CNG variants, where available:

The Hyundai Aura leads the segment, especially with its CNG variant, in terms of mileage among the most diesel-only players that lack factory-fitted CNG versions.

Summary

The Hyundai Aura CNG model truly stands out in terms of fuel efficiency and overall running costs. Its impressive mileage ensures that owners can save significantly on fuel expenses over time, making it a convenient choice for budget-conscious buyers. Moreover, the CNG variant manages to offer this efficiency without compromising on essential aspects.

The lower running expenses of the CNG model are particularly advantageous for individuals who commute daily within the city or frequently drive short distances, as the reduced cost per kilometre adds up to noticeable savings over time. 

In contrast, the petrol version, although less fuel-efficient, delivers greater power and smoother acceleration, which can be especially appealing for drivers with longer daily commutes or who often travel on highways. 

Ultimately, deciding between the petrol and CNG versions of the Hyundai Aura depends on a combination of factors, including your typical travel distance, local fuel availability, and your preference for performance versus economy.
