Automobile modifications are subject to certain restrictions, and arbitrary modifications may likely fail the annual inspection. Here are the specific details: 1. Car modifications must be carried out in compliance with relevant regulations: Currently, the traffic management authorities still impose strict restrictions on car modifications. Technical parameters such as engine displacement absolutely cannot be modified privately. 2. Modifications to the body color, engine, fuel type, and frame number are allowed: However, there are three colors reserved for special vehicles that cannot be used. Red is designated for firefighting, yellow for engineering and emergency rescue, and white over blue for national administrative law enforcement. Changes to the body, frame, or engine can only be made if they are damaged beyond repair or have quality issues. When applying for modifications, proof from a repair shop and documentation of the origin of the replacement engine, body, or frame must be provided. 3. Modifications such as widening tires, modifying the intake system, or exhaust system are not permitted: According to the relevant provisions of the Ministry of Public Security's "Motor Vehicle Registration Regulations," changing tire specifications, modifying the intake system, or exhaust system on in-use vehicles are not allowed under national regulations.

What are the body dimensions of the Infiniti Q50L?

The length, width, and height dimensions of the Infiniti Q50L are 4867mm/1823mm/1456mm, which are official data. The length of the Infiniti Q50L refers to the distance between two vertical planes perpendicular to the vehicle's longitudinal symmetry plane and touching the outermost protruding parts at the front and rear of the car; the width refers to the distance between two planes parallel to the vehicle's longitudinal symmetry plane and touching the outermost rigid fixed protruding parts on both sides of the vehicle; the height refers to the distance between the highest point of the vehicle and the supporting plane of the vehicle. The turbocharged engine of the Infiniti Q50L has a maximum power of 155kW and a maximum torque of 350Nm. This engine reaches its maximum power at 5500 rpm and its maximum torque between 1500 and 3500 rpm. It features direct fuel injection technology and uses an aluminum alloy cylinder head and block. This engine is paired with an automatic transmission (AT). The national regulations on vehicle dimensions include relevant stipulations. According to the national standard 'GB1589-89', the total width of a vehicle does not include side mirrors. The limitation on vehicle width is to provide sufficient lateral clearance for overtaking between adjacent lanes. This means that, under national standards, the significance of vehicle width data lies in ensuring enough space during overtaking, preventing accidents due to excessive width or situations where road markings are narrower than the vehicle's width. Additionally, national regulations stipulate that the total width of a vehicle must not exceed 2.5m to meet the usage requirements of public roads.
