Today, the American truck simulation will welcome a new truck brand: Mack. The hood, grille and cab with sleeper of the Mark truck are designed according to aerodynamic principles, which not only have a beautiful appearance, but also contribute to efficient work. The streamlined rectifiers on the roof, sides and chassis allow air to flow smoothly along the front and body, reducing the drag coefficient and saving fuel. The design of forward cab movement, power steering, 45-degree wheel steering angle and straight The power transmission system improves the flexibility of the vehicle, Help drivers easily enter and exit the narrow spaces of the city. The rear axle moves backward and the distance between the bumper and the rear end of the cab is very short, which ensures the effective distribution of vehicle weight during road and off-road operations. The front of the frame is spread out. In this way, the engine can be installed in a lower chassis position, which increases the stability of the vehicle on rough terrain, and it is more convenient for the driver to enter and exit the vehicle. The streamlined rearview mirror has a visible range of 110 square inches, With a double-arm support system, vibration is reduced, and the detachable design reduces the risk of damage. Vision also has the longest, widest and brightest headlight beams of any truck, ensuring optimal road and sign lighting and helping to reduce eye fatigue.
