Sportmatic is a function of manual shifting in automatic transmissions installed on Kia cars. It is offered either as a factory-installed equipment or as an option for most current versions. It has been in use since 2001. This function improves the vehicle’s performance compared to a classic automatic transmission.
The Sportmatic function is based on classic automatic transmissions with a torque converter and planetary gear sets. Its firmware allows for manual gear shifting. The control unit receives information about the gear the driver has selected and locks it in a specified range until a certain moment. In order to switch to manual mode, move the gear lever from the “D” position to the left. After this, a corresponding indicator will light up on the selector, warning about engaged manual mode. Move the lever to “+” or “-” to shift gears up or down respectively.
