Is the Fuel Consumption Data from MIIT Reliable?
2 Answers
The fuel consumption data released by the Ministry of Industry and Information Technology (MIIT) is relatively reliable, but it is only theoretical data and can only serve as a reference. Below is some relevant information about fuel consumption: 1. Fuel consumption per 100 kilometers: This refers to the amount of fuel a vehicle consumes when driving a certain distance at a specified speed. It is a theoretical indicator for vehicles. Manufacturers measure this value in an objective environment using a dynamometer installed on the vehicle's chassis, converting it into speed parameters, and then calculating the theoretical experimental fuel consumption per 100 kilometers for the model at specified speeds. 2. Road condition fuel consumption: This is a fuel indicator calculated based on repeated tests where the vehicle is driven on specified roads at prescribed speeds and times. It is also known as multi-condition road cycle fuel consumption. The standard specifies that each cycle includes various driving conditions, and records the driving conditions based on indicators such as specified gear-shifting times, parking durations, driving speeds, acceleration, braking, and deceleration for each cycle. The values obtained through this method are closer to actual usage.
I've been driving for over a decade and gone through three cars. Every time I see the fuel consumption figures posted by the Ministry of Industry and Information Technology, I can only chuckle. These numbers are all measured in labs, with cars running fixed test cycles on dynamometers under perfectly controlled temperature and humidity conditions – they don't even account for wind resistance. But real-world driving? You've got AC blasting in summer, stop-and-go traffic guzzling fuel, and winter cold starts from underground garages that can push consumption 30% above those official figures. So don't take those numbers too seriously – treat them as reference points and focus on your actual commute conditions. For my daily route mixing inner-ring highways with city driving, I always add 1.5L to the official numbers to get realistic estimates.
