Should I Use D Gear or S Gear for Highway Driving?

For highway driving, using D gear is sufficient, while S gear can be employed during aggressive driving or overtaking. Automatic transmissions are equipped with an S gear, where 'S' stands for 'Sport,' indicating the sport mode. When switched to S gear, the transmission enters sport mode, and the engine's operation mode will also adjust accordingly. In S gear, the transmission delays shifting, only upshifting when the engine reaches the redline. D gear is the forward drive gear for automatic cars. When in D gear, the car actively upshifts to maintain lower RPM levels. Common automatic transmission gears include P (Park), N (Neutral), D (Drive), R (Reverse), S (Sport), and L (Low).

Is the SWM X7 fuel-consuming?

Not very fuel-consuming. The SWM X7 has 11 models currently on sale. Among them, the 2021 facelift models include the 1.5T automatic Elite Edition 6-seater, automatic Elite Edition 7-seater, automatic Zhiyun Edition 7-seater, and automatic Elite Edition 5-seater, all equipped with a 156-horsepower engine, with an NEDC fuel consumption of 8L per 100km. The 2020 models include the 2.0L manual Comfort Edition 5-seater, manual Elite Edition 5-seater, manual Comfort Edition 7-seater, and manual Elite Edition 7-seater, all equipped with a 137-horsepower engine, with an NEDC fuel consumption of 7.9L per 100km. The 2020 models also include the 2.0L manual Champion Edition 7-seater, manual Champion Edition 6-seater, and manual Champion Edition 5-seater, all equipped with a 143-horsepower engine, with an NEDC fuel consumption of 7.9L per 100km. The fuel tank capacity of different SWM X7 models is the same. The distance that can be covered with a full tank of fuel is as follows: For models equipped with a 156-horsepower engine and an NEDC fuel consumption of 8L per 100km, the fuel tank capacity is 54L, and the distance that can be covered with a full tank is 54/8*100=675km. For models equipped with a 137-horsepower engine and an NEDC fuel consumption of 7.9L per 100km, the fuel tank capacity is 54L, and the distance that can be covered with a full tank is 54/7.9*100=684km. For models equipped with a 143-horsepower engine and an NEDC fuel consumption of 7.9L per 100km, the fuel tank capacity is 54L, and the distance that can be covered with a full tank is 54/7.9*100=684km. The fuel consumption of a car is directly related to five major factors: driving habits, the car itself, road conditions, natural wind, and environmental temperature. Specific factors that can increase fuel consumption are as follows: Driving habits: Rough driving can increase fuel consumption. The car itself: Cars with larger displacements consume more fuel than those with smaller displacements because larger displacements generally mean higher power, requiring more gasoline to burn and perform work. Heavier cars consume more fuel because greater weight requires more driving torque. Road conditions: Driving on dirt roads, muddy roads, soft surfaces, or mountainous roads increases resistance and fuel consumption. Natural wind: Driving against the wind or on windy days increases car resistance and fuel consumption. Low environmental temperatures: When the engine block temperature is low, the gasoline injected during cold starts is less likely to atomize, requiring more gasoline to be injected for combustion, thus increasing fuel consumption. Additionally, at low temperatures, the engine computer controls the engine to run at higher RPMs to warm up, which also increases fuel consumption.
