What is the maximum speed of the Highlander?

185 km/h is the maximum speed of the Highlander. The maximum speed refers to the highest driving speed that a car can achieve on a road with good horizontal conditions. It is the speed at which the driving resistance and driving force are balanced under windless conditions on a flat road surface. The Highlander is equipped with a 2.0T turbocharged engine with a maximum power of 162 kW and a maximum torque of 350 Nm. There are many factors that affect the maximum speed of a car, such as the power of the car's engine, the maximum torque of the engine, the speed at maximum torque, the transmission ratio of the drivetrain, and driving resistance. The maximum speed is obtained on a flat and windless road surface with zero acceleration, so the gradient resistance and acceleration resistance are zero. Therefore, the main resistance factors affecting the maximum speed are air resistance and rolling resistance. Automotive air resistance refers to the component of the air force acting on a car moving in a straight line in the direction of travel. Air resistance is directly proportional to the square of the speed. Therefore, high-speed driving has a very obvious impact on air resistance. At high speeds, the engine must use a considerable part of its power, or fuel energy, to overcome air resistance. Automotive rolling resistance refers to the resistance opposite to the direction of rolling when an inflated tire rolls in a straight line on an ideal road surface (usually a flat, dry, and hard road surface), with the central symmetrical plane of its outer edge aligned with the direction of wheel rolling.
