1.6L manual luxury model fuel consumption: 6.6L/100km; the actual fuel consumption for the 1.6L manual luxury model is likely around 9 to 10 liters. Main factors affecting fuel consumption include the following: Insufficient tire pressure: Maintaining proper tire pressure is also a good way to reduce fuel consumption. If tire pressure is insufficient, rolling resistance will significantly increase. According to tests, if tire pressure is 2psi (unit: pounds per square foot) below the recommended value, fuel consumption will increase by 1%. Additionally, misaligned or excessively worn tires can also increase fuel consumption. Low gear at high speed: Driving at low gear with high speed often occurs among novice drivers or those who are distracted while driving. Tests have shown that driving long distances at high speed in 3rd gear can increase fuel consumption by 10% compared to normal driving in 4th gear. Using 2nd gear instead of 3rd gear will further increase fuel consumption.

My 2021 1.5L CVT Elantra has been running for two and a half years, with a daily commute of 25 kilometers on urban roads. When there are many traffic lights, the displayed fuel consumption can reach around 8.2L, while on weekends, highway driving can bring it down to 5.8L. The most fuel-efficient state is maintaining a steady speed of 60-80 km/h. Using the air conditioning increases fuel consumption by about 1L. Don't fill the tank too full, and keep the tire pressure at 2.5—these details can really save a lot on fuel costs. Remember to avoid heavy acceleration and sudden braking; fuel efficiency largely depends on your driving technique.

A few days ago, I helped my neighbor test drive his newly purchased second-hand Elantra, the 1.4T dual-clutch model. Turbocharged cars are indeed more powerful but also more fuel-consuming. During rush hours in the city with the air conditioning on, the fuel consumption directly soared to 9.3L. On the outer ring road at a steady speed of 70 km/h, it could be reduced to just over 6L. I advised him to use Sinopec 95-octane gasoline and not to go for cheap gas at small stations. Another tip: don’t set the air conditioning to the maximum in summer; lowering it by one notch can save 0.5L of fuel.

Is the steering wheel of the Audi A4 made of genuine leather?

The steering wheel of the Audi A4 is made of genuine leather. Steering Wheel: It is a wheel-shaped device used to control the direction of cars, ships, airplanes, etc. Its function is to convert the force applied by the driver to the edge of the steering wheel into torque, which is then transmitted to the steering shaft. It mainly consists of a skeleton, foam, and mounting clips or screw holes corresponding to the driver's airbag (DAB). Audi A4: It is a B-segment car manufactured by FAW-Volkswagen. The FAW Audi A4 is sold in three engine displacements: 1.8T, 2.4, and 3.0. The 1.8T comes in four variants: Manual Basic, Automatic Basic, Comfort, and Technology Leading.

Why does the car shake when warm but not when cold?

Reasons for engine shaking when warm are as follows: 1. Injector malfunction: Uneven fuel injection or poor atomization from the injectors leads to imbalanced power output among cylinders. 2. Fuel pressure issues: Low pressure causes poor fuel atomization or linear fuel spray (in severe cases just dripping), reducing injection quantity and creating a lean mixture. High pressure increases actual fuel injection, creating a rich mixture. 3. Spark plug problems: Incorrect spark plug gap; eroded or damaged electrodes; carbon buildup on electrodes; cracked spark plug insulators.

Why does the car's cooling fan keep running?

There are several reasons why a car's cooling fan may continue to run: 1. If you notice the radiator fan running immediately after turning off the engine, wait for a while. The water temperature in the radiator decreases slowly, and the cooling fan may continue to operate for some time before stopping when the engine is first turned off. 2. If the car has completely cooled down but the fan still keeps running, there might be a fault in the cooling fan assembly or its wiring. 3. The fan in the car serves a cooling function. After parking, if the coolant temperature is too high, the vehicle's computer will automatically calculate the fan's speed and duration. The higher the temperature, the longer the fan will run to protect the engine, which is a normal phenomenon.
