How does switching a car into sport mode work?
In: 666
In an automatic transmission, the vehicle decides when to shift based on engine speed and throttle position. In regular driving mode, it favors engine speeds that are more fuel efficient.
It’ll roughly have a target engine speed. When above that speed, it tries to shift up. When below, it tries to shift down. Throttle position impacts when it shifts. The more open the throttle, the more it wants to downshift or prevent upshifting.
In “Sport” mode, the target engine speed is higher, so it’ll let the engine rev up higher before it upshifts. Using higher RPM in a lower gear gets better power output at the expense of fuel efficiency.
