Sport mode is a feature found in many modern cars that is intended to enhance the performance of the vehicle by sharpening how it responds to a drivers inputs. When activated, Sport mode tells the cars computers to adjust certain settings, such as throttle sensitivity and the transmissions shift points (assuming it’s an automatic) . This can result in a more aggressive throttle response, heavier steering, and a stiffer suspension, among other changes. Sport mode is most useful when you want to explore your cars full performance capabilities, such as on a track or an engaging stretch of road. However, it is not recommended to use it while commuting, as it can decrease gas mileage and cause accelerated engine and tire wear.
Activating Sport mode is often as simple as pushing a button or twisting a dial, and it requires no vehicle preparation. Some models offer an enhanced Sport mode (usually called Sport Plus) that can further dial back stability and traction control while adding extra bite to the transmission and throttle programs. It is important to note that driving in Sport mode must be at the right moment, and it should only be used in a safe environment, like on a track.
