The highway fuel consumption of the Hyundai Elantra is 7.1 liters per 100 kilometers. Below is the related content: Highway fuel consumption: Fuel consumption per 100 kilometers refers to the amount of fuel a vehicle consumes when traveling a distance of 100 kilometers at a certain speed on the road. It is a theoretical indicator for the vehicle. The fuel consumption per 100 kilometers is a value measured by the manufacturer in an objective environment using a dynamometer installed on the vehicle's chassis, converted into speed parameters, and then calculated as the theoretical experimental fuel consumption data for the model when traveling at a specified speed. Reasons for high vehicle fuel consumption and solutions: Engine carbon deposits: During long-term operation of the vehicle, carbon deposits and sludge are inevitably produced during the combustion of gasoline. If these deposits and sludge are not cleaned in time, they will lead to increased fuel consumption. The solution is to clean the engine carbon deposits. Spark plug failure: The function of a car's spark plug is to ignite the air-fuel mixture with a high-voltage electric spark. If damaged, the ignition energy will decrease, causing uneven combustion of the mixture, which will result in slower acceleration and increased fuel consumption. The solution is to replace the spark plug or clean the carbon deposits on the spark plug.

I've been driving a Hyundai Elantra for almost five years now, and the fuel consumption on highways is generally around 6.2 liters per 100 kilometers, which is quite fuel-efficient. I often take long trips, and the most economical speed is around 100 km/h. A full tank can take me over 600 kilometers. Turning on the AC in hot weather does increase fuel consumption a bit, but not significantly, and carrying family or luggage doesn't really affect it much. I maintain the car by changing the oil on schedule and keeping the tire pressure at the recommended level. The engine is well-designed, contributing to the low overall fuel consumption. Fuel efficiency is one of the Elantra's strengths, making it suitable for daily commutes or road trips, helping you save a lot on fuel costs. From my experience, it feels even more economical than some Japanese cars in the same class.

How to Deal with Fog on the Car's Front Windshield?

Methods to handle fog on the car's front windshield include: 1. Open the windows; 2. Use defogging spray; 3. Turn on the warm air from the air conditioner; 4. Activate the car's defogging function; 5. Apply a mixture of dish soap and water or soapy water to the windshield; 6. Place a dehumidifier box inside the car; 7. Wipe with a towel; 8. Increase the fan speed and turn on the cooling switch. The reason for fog formation on the car's front windshield is the temperature difference between the inside and outside of the car, where the higher temperature inside the cabin causes moisture to condense on the inner surface of the windshield, forming fog. Preventive measures include: 1. Use specialized defogging products before driving; 2. Utilize the air conditioner's cooling and dehumidifying functions to reduce air humidity.
