Reasons for gasoline smell in the car: 1. Aging rubber pipes of the gasoline vapor canister: In older vehicles, rubber components in the engine compartment are prone to aging. The pipes connecting the canister to the throttle may leak into the engine compartment if they age, requiring timely replacement; 2. Leakage at gasoline pipe connections: If gasoline pipes leak, the smell may enter the car through the air conditioning system, forming a layer of grease over time, necessitating tightening or repair; 3. Poor sealing after fuel pump disassembly: Some owners may replace or disassemble the fuel pump, and gasoline smell in the car could result from residual substances not being cleaned properly post-disassembly. It is advisable to have the fuel pump installation checked at a repair shop; 4. Overfilling the fuel tank: Filling the tank too full can easily cause a gasoline smell inside the car.

Is the Geely New Vision Front-Wheel Drive or Rear-Wheel Drive?

Geely's New Vision is front-wheel drive. Advantages of front-wheel drive vehicles: Good handling, with more agile vehicle response during steering. Additionally, they offer excellent acceleration performance from a standstill and high comfort levels. When the vehicle starts, accelerates, or climbs a slope, the center of gravity shifts backward, increasing the traction of the rear wheels as driving wheels, which is beneficial for starting, accelerating, or climbing, providing better driving stability and comfort. Disadvantages of front-wheel drive vehicles: The drawbacks of front-wheel drive vehicles include higher manufacturing costs and inconvenient space utilization. During turns, if the rear wheels rotate faster than the front wheels, oversteering can occur, commonly referred to as "tail sliding."

What is the approach angle of a car?

The approach angle of a car is the maximum angle between the horizontal plane and the plane tangent to the outer edge of the front wheel tires. The approach angle is one of the indicators to measure a car's passability. A larger approach angle means the car is less likely to experience a nose-dive accident, but it does not solely determine the car's passability or off-road capability. Other parameters and actual conditions must also be considered. For some vehicles with adjustable suspensions, the approach angle is not fixed because the body height can be adjusted. The approach angle is not only important for SUVs; sedans also need a certain level of passability. Situations like mounting curbs, small steep slopes, or boarding ferries can be encountered in daily driving, and a larger approach angle helps prevent nose-dive accidents.
