Can You Use S Mode on the Highway?
2 Answers
S mode can be used on the highway, but it is not recommended for prolonged use. This is because S mode only delays gear shifting without altering other operational aspects, inevitably increasing the transmission load in the short term, raising temperatures, and accelerating wear. Additionally, vehicle comfort is slightly reduced in S mode, so it's best to avoid extended use. Below is relevant information: 1. Due to its strong power, S mode is typically used for overtaking or climbing hills. After completing these actions, it's advisable to switch back to the more economical D mode. From a fuel consumption perspective, S mode consumes significantly more fuel than normal mode due to increased fuel injection at high RPMs, and it also tends to wear the transmission more. Therefore, it's unnecessary for everyday driving. 2. Although S mode isn't frequently used, it does have benefits. For vehicles often driven in congested urban areas, where engine carbon buildup is common, periodic use of S mode can help remove carbon deposits, improve fuel economy, and extend engine life.
I often use the S gear on the highway, especially when overtaking on less crowded roads—the response is super quick, and the ride is incredibly smooth. However, I remind myself not to keep it on all the time because the S gear keeps the engine RPM higher, increasing fuel consumption, which isn’t cost-effective for long trips. It’s more comfortable and fuel-efficient to switch back to D gear when cruising, providing a steady ride. Cars are like people—engines wear out faster under prolonged high loads, so moderation is key. Safety-wise, quick acceleration on the highway is great, but always mind the distance—don’t prioritize thrill over stability. Overall, using S gear is fine, but know when to switch back.
