Audi not being able to turn properly refers to the understeer of an Audi. Generally, when a vehicle is turning, it completes the turn based on the driver's control of the steering. When the vehicle fails to turn as expected and exhibits insufficient steering, it is referred to as "understeer." The drivetrain configuration can have some influence on a car's understeer phenomenon. Impact of Front-Wheel Drive (FWD) Vehicles: Only front-wheel drive vehicles are more prone to understeer because the weight distribution of such drivetrain configurations is concentrated on the front. In this "top-heavy" situation, the car is more likely to experience insufficient front-wheel grip during turns. Additionally, since the front wheels are responsible for both driving and turning, applying throttle while exiting a turn can easily lead to understeer. Impact of Rear-Wheel Drive (RWD) Vehicles: Understeer is much less common in these vehicles. When driving at high speeds, it is easier to get the front end to turn into a corner. The downside of rear-wheel drive vehicles is their tendency to oversteer. Impact of All-Wheel Drive (AWD) Vehicles: AWD vehicles have the highest stability during turns because the wheels of such drivetrain configurations have the greatest friction, making them less prone to slipping during turns. Therefore, the occurrence of understeer or oversteer in these vehicles is significantly lower compared to FWD and RWD vehicles.

How many bars on the temperature gauge are normal?

It is normal for the temperature gauge to show 2 to 4 bars. When the car's engine is operating normally, the water temperature is typically between 90 degrees Celsius and 105 degrees Celsius, which is the midpoint on a simplified gauge. If the car's water temperature becomes too high, it can lead to poor engine cooling. The expansion of components will reduce the clearance between parts, and on the other hand, high temperatures will lower the viscosity of engine oil, increasing wear on components. To ensure the engine operates within the normal temperature range, cars are equipped with an engine coolant temperature sensor. Usually, the temperature gauge is displayed separately on the car's dashboard, and an alarm will appear if the antifreeze temperature is too high.

What Causes a Tire Blowout?

Causes of car tire blowouts include low tire pressure, overinflation, improper installation, lack of proper maintenance, tire wear and aging, sidewall bulges, manufacturing defects, and severe impacts. Below are additional details: Measures to prevent tire blowouts: Replace tires in a timely manner, perform wheel alignment and tire balancing, rotate front and rear tires, maintain proper tire pressure, and avoid speeding. How to handle a tire blowout: Hold the steering wheel firmly, adjust the direction gently, avoid sudden steering movements, refrain from slamming the brakes, and wait for the vehicle to slow down gradually before steering lightly; set up a warning triangle behind the vehicle to prevent secondary accidents.

What does Aowei 11-liter mean?

Aowei 11-liter refers to the engine's displacement. Displacement: Displacement refers to the exhaust volume, which is the volume swept by the piston from top dead center, also known as single-cylinder displacement, and depends on the cylinder bore and piston stroke. The displacement of an internal combustion engine is the sum of the working volumes of all cylinders, usually expressed in liters (L). Working Principle: Exhaust volume is the gas expelled by the piston from one stroke to another during the engine's operation when a specific cycle delivers air into the cylinder. Theoretically, during the exhaust stroke, the exhaust gas in the cylinder should be completely expelled by the piston, hence it is often referred to as 'piston displacement'.

How to Check if the Front of the Car is Aligned from Inside the Vehicle?

Methods to check if the front of the car is aligned from inside the vehicle: You can use the wipers and road markings as reference points, maintaining a fixed distance or angle while driving. If the car deviates, it indicates the front is not aligned. When adjusting the steering wheel, avoid large movements as this can easily cause the vehicle to shake and lose control. Keep adjustment movements within the range of half a finger width to three finger widths. Another important aspect regarding the steering wheel is the grip. An incorrect grip can also lead to misalignment of the front of the car. Therefore, the correct grip is the '9 and 3 o'clock' position. While holding the steering wheel, the left hand should primarily control the steering, while the right hand rests lightly on it for easy gear shifting.
