Hyundai Exter ARAI Mileage Figures

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

Hyundai Exter Real-World Mileage vs ARAI Mileage

Though ARAI mileage figures are obtained under controlled conditions, real-world driving is quite different. In typical city traffic, the Hyundai Exter petrol manual delivers 19.15 km/l, while the automatic petrol variant manages 17.8 km/l. The CNG version offers 22.2 km/kg in city driving and aligns more closely with its official figure on highways.

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

1. Driving Style: Aggressive acceleration and sudden braking reduce fuel efficiency.
2. Traffic Flow: Stop-and-go city traffic lowers mileage compared to open highways.
3. Load & Air-Conditioner Usage: Carrying extra passengers or running the AC extensively increases fuel consumption.
4. Maintenance: Regular servicing, clean air filters, and correct tyre pressure help sustain optimal mileage.

For most buyers, the Hyundai Exter’s real-world fuel efficiency is competitive in its segment, with the CNG variant providing the most economical option for frequent drivers.

Hyundai Exter Fuel Efficiency Comparison: Petrol vs CNG

In terms of fuel economy, the Hyundai Exter’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. On the other hand, the CNG variant, with its dual-cylinder setup, is designed to maximise fuel cost savings, especially 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 Exter City Fuel Efficiency Comparison

City driving for Hyundai Exter petrol variants generally delivers decent fuel efficiency, but tends to consume more fuel due to frequent stops and starts. Automatic petrol variants are slightly less efficient than manual ones because of the torque converter. The CNG model, however, proves to be far more economical for regular city commutes, especially in congested traffic.

The main factors for the difference are:

1. Fuel Characteristics: CNG burns cleaner and more efficiently at lower speeds, offering better mileage in stop-and-go traffic. It is particularly suitable for city driving with frequent congestion.
2. Engine Calibration: The CNG variant’s economy mode optimises fuel use during slow-moving traffic, keeping the engine at lower revs and boosting mileage.
3. Traffic Conditions: Petrol engines require extra fuel for sudden acceleration in heavy traffic, whereas CNG engines handle steady, slow traffic more efficiently.
4. Idle Efficiency Time: CNG engines consume less fuel while idling in traffic compared to petrol engines, resulting in superior city mileage.
5. Heat Control: Petrol engines tend to heat more in stop-and-go conditions, which reduces efficiency, while CNG engines maintain consistent running temperatures, improving overall fuel economy.

Hyundai Exter Highway Fuel Efficiency Comparison

On the highway, Hyundai Exter petrol models generally offer better mileage with smooth cruising and gentle braking. Petrol manuals usually deliver higher fuel efficiency than automatic variants due to direct power transfer. The CNG version provides decent highway economy but may feel slightly less responsive during overtaking because of lower output.

The factors affecting highway mileage differences include:

1. Cruising Efficiency: Petrol engines perform more efficiently at higher speeds, though CNG remains cost-effective per kilometre, making long-distance travel more economical.
2. Load and Air-Conditioning Consumption: Fuel efficiency for both petrol and CNG drops when the car is fully loaded or the AC is used extensively, with a more noticeable effect on the CNG variant.
3. Driving Habits: Smooth acceleration and maintaining a steady speed are crucial for maximising mileage in both petrol and CNG variants. Frequent hard acceleration or abrupt braking reduces fuel efficiency.
4. Altitude and Terrain: Driving on hilly or mountainous terrain impacts fuel consumption, with petrol engines generally handling gradients better due to higher power output.
5. Fuel Availability and Refuelling Stops: Long highway trips require planning fuel stops, especially for CNG, as accessibility can affect overall travel efficiency and indirectly influence mileage.

Hyundai Exter Fuel Cost Comparison: Petrol vs CNG

Knowing the fuel expenses is crucial when choosing between the Hyundai Exter petrol and CNG models. Let’s examine the running costs for an average monthly distance of 1,500 km, along with other factors, to help you determine which variant is more budget-friendly.

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 Exter CNG variant offers much lower running costs, making it a more economical choice for drivers covering long distances.

Hyundai Exter Mileage vs Competitors

Examining the Hyundai Exter’s mileage alongside its key competitors gives a clear picture of its fuel efficiency. Below are the official mileage figures for both petrol and CNG variants, wherever available:

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

Summary

The Hyundai Exter CNG model truly stands out when it comes to fuel efficiency and overall running costs. Its impressive mileage ensures that owners can save significantly on fuel expenses over time, making it a highly practical 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 comparatively less fuel-efficient, delivers greater power and smoother acceleration, which can be especially appealing for drivers who have longer daily commutes or often travel on highways. 

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