What is the actual fuel consumption of the Changan CS75 Plus 2.0T?

The comprehensive fuel consumption of the Changan CS75 Plus 2.0T is 8.1L/100km. There are currently two models of the Changan CS75 Plus 2.0T on sale: the Automatic Flagship and the Automatic Navigator, both with a comprehensive fuel consumption of 8.1L/100km. The above figures are NEDC comprehensive fuel consumption, which is the fuel consumption data measured under the NEDC test procedure. The actual fuel consumption is higher than this value, ranging from 9.7-12.0L/100km. When driving, the following five tips can help reduce fuel consumption: When starting the vehicle, use a low gear, gently press the accelerator, and gradually increase speed. Avoid suddenly pressing the accelerator hard, as this can multiply fuel consumption. Light acceleration, light braking, and early braking: While driving, gently press the accelerator to avoid sudden increases in engine speed and prevent the car from shaking during operation, thus making the car more fuel-efficient. By anticipating road conditions and adopting slow and uniform acceleration or braking, fuel economy can be improved by up to 20%. Maintain proper tire pressure: Keep tire pressure at the level recommended by the manufacturer. For every 2 PSI below the recommended value (equivalent to about 0.2 in metric units relative to the standard pressure of 2.4), fuel consumption increases by 1%. Regular maintenance or vehicle checks: Regular oil changes can reduce carbon buildup (carbon buildup can cause ignition issues, sluggish acceleration, increased fuel consumption, and in severe cases, even cylinder misfires). Regularly check and replace dirty air filters, clean or replace fuel injectors, spark plugs, and throttle bodies as per mileage. Close windows while driving. Driving with windows open increases wind resistance, which in turn increases the resistance the car faces, requiring more power and thus increasing fuel consumption.
