Are China VI Standard Vehicles Fuel-Efficient?

[VivianRose]

China VI refers to vehicles with lower carbon emissions, meaning reduced pollution levels. The China VI emission standard is not directly related to a vehicle's fuel efficiency. Below are different scenarios regarding the fuel consumption of China VI standard vehicles: 1. Slightly higher fuel consumption in practice. Given China's actual conditions, it is highly possible that China VI vehicles may consume more fuel compared to China V emission vehicles of the same displacement and model. 2. Theoretically more fuel-efficient. From a theoretical perspective, higher emission standards imply more advanced engine technologies. Applications of new technologies such as turbocharging, direct fuel injection, variable valve timing, smaller displacement with higher compression ratios, and Atkinson cycle engines allow more complete combustion of the same amount of fuel, resulting in higher combustion efficiency. Theoretically, this should lead to better fuel efficiency, but this remains only a theoretical assumption.
