What transmission does the Volvo S90 use?
1 Answers
The Volvo S90 comes standard with an 8-speed automatic transmission, which can quickly respond to changes in engine speed, providing smooth gear shifts. The multiple switchable gear ratios mean the engine's torque and power range can be effectively utilized. Two of the gears are overdrive gears, which can save fuel when driving at a constant engine speed. Manual gear selection is also available, and the current gear position can be displayed on the driver's display. Additional information: 1. The transmission is one of the main components of a car's drivetrain. The actual usage conditions of a car are very complex, such as starting, idling and stopping, low or high-speed driving, accelerating, decelerating, climbing hills, and reversing. This requires the car's driving force and speed to be variable within a considerable range, while the output torque and speed variation range of the widely used piston engine is relatively small. 2. To adapt to frequently changing driving conditions and allow the engine to operate under favorable conditions (higher power, lower fuel consumption), a transmission is installed in the drivetrain. Each gear has a different gear ratio, equivalent to the meshing of small and large gears producing different speeds. Low gear ratios (3rd gear and below) are used for low-speed driving, where the main shaft speed is lower than the engine speed, providing greater driving force. High gear ratios (4th gear and above) are used for high-speed driving, where the main shaft speed is higher than the engine speed, reducing traction to achieve higher speeds. Shifting gears means selecting different-sized gears to mesh with the main shaft gear.
