Hyundai Grand i10 Real-World Mileage vs ARAI Mileage
The ARAI-rated mileage is obtained under ideal laboratory conditions, but this does not accurately reflect the actual mileage in real-life driving. In regular city traffic, the Grand i10 manual petrol variant achieves a fuel efficiency of about 19 to 22 km/l. The CNG variant, being economic, achieves a fuel efficiency of 19 to 22km/kg under city conditions.
Some of the factors contributing to the difference between ARAI and the actual mileage are:
- Driving Style: Frequent gear changing, harsh brakes and sudden acceleration decrease fuel economy.
- Traffic Flow: Traffic jams and frequent braking on the streets result in decreased mileage compared to calm highway driving.
- Load & AC Usage: Taking on extra passengers or running the air conditioner continuously increases fuel consumption.
- Maintenance: Regular maintenance, including cleaning air filters and ensuring tyres have adequate air pressure, can help sustain maximum mileage.
The Grand i10 offers competent real-world fuel economy in its category, making it a suitable choice for most buyers. In this regard, the CNG variant is the most cost-effective option for users with extensive daily running and can be quite cost-effective in the long term.
Hyundai Grand i10 Fuel Efficiency Comparison: Petrol vs CNG
When discussing fuel economy, it is interesting to note that both petrol and CNG versions of the Hyundai Grand i10 cater to distinctly different driving requirements.
The petrol version strikes an excellent balance between power and efficiency, which makes it an excellent commuter unit when taken out on the highways occasionally. On the contrary, the CNG version is optimised to make the most out of fuel savings, offering an attractive output to users who cover a considerable distance each day.
When it comes to daily driving, particularly in heavily populated and stop-and-go urban settings, the two types of fuel record tangible variations in consumption. As consistently observed through real-world data, driving habits and traffic conditions can prove to be critical variables in determining which variant proves more cost-effective in the long run.
Hyundai Grand i10 City Fuel Efficiency Comparison
Petrol variants offer decent mileage in the city but tend to consume more fuel due to frequent stops, especially in automatic models with torque converter gearboxes. It is, instead, much more cost-effective to use the CNG variant when commuting daily in the city and during heavy traffic.
Urban driving can look simple enough, but it puts a great deal of strain on your engine, burning fuel at an unexpected pace. Here’s how:
- Lingering in Lower Gears: Spending time idling in first or second gear will spike your RPMs into the red and burn a significant amount of fuel, especially in rush-hour traffic.
- AC Drain While Idling: In smaller cars, such as the Grand i10, the air conditioner can strain the engine when turned on during idle, a fact that is readily apparent in the significant decrease in mileage.
- Frequent Short Trips: Engines consume more fuel when cold. Short trips that prevent optimal engine temperature result in poor fuel economy due to inefficient engine combustion.
- Sudden Bursts of Acceleration: Stomping on the throttle after a stop not only consumes gas, but it also prematurely wears out the clutch.
- Underinflated Tyres: Even a minor loss of 3-4 PSI below the recommended pressure will increase rolling resistance, causing the engine to work harder and reducing fuel efficiency and mileage.
Hyundai Grand i10 Highway Fuel Efficiency Comparison
Over highways, petrol variants usually offer a higher level of fuel efficiency due to the regular cruising and smooth braking. Manual petrol models are more efficient in terms of mileage compared to automatics due to less indirect power transmission.
Although the CNG version is similarly efficient on the highway in terms of economy, it can be slightly underpowered when overtaking due to its reduced output. Due to poor driving habits and overloading, your Grand i10 can significantly reduce its mileage, even on the highway. The following tips should be remembered:
- Speeding Beyond 100 km/h: The Grand i10 achieves the best mileage at speeds of 80 to 90 km/h. Faster speeds increase air drag, which causes the engine to consume more fuel. Travelling at a velocity of more than 100 kilometres per hour may lead to a noticeable loss of efficiency.
- Sudden Acceleration or Braking: Rapid acceleration and rough braking are two major factors that can significantly reduce fuel efficiency. Driving at a constant rate keeps the fuel consumption optimum, especially in city traffic.
- Opening Windows at High Speed: Opening windows at highway speeds creates drag and reduces fuel efficiency. Amazingly, it is more economical to run the AC at high speed compared to leaving open windows.
- Overloaded Boot: Extra weight strains the engine, causing it to consume more fuel. This is particularly noticeable on long drives or steep climbs. Carrying only essentials boosts mileage.
- Misaligned Tyres: Misalignment increases the rolling resistance, causing the engine to produce more energy. Periodic inspection enhances mileage, the service life of tyres, and safety.
