Is the fuel consumption display per 100 kilometers accurate for the Baojun 310W?

The fuel consumption displayed on the dashboard is definitely not completely accurate and can only serve as a reference. Introduction to the Car Dashboard: The car dashboard is a device that reflects the working conditions of various systems of the vehicle. Common indicators include the fuel indicator, washer fluid indicator, electronic throttle indicator, front and rear fog light indicators, and warning lights. Introduction to the Tachometer: The tachometer is generally located within the instrument panel, placed symmetrically with the speedometer. The tachometer operates based on magnetic principles. It receives pulse signals generated when the primary current in the ignition coil is interrupted and converts these signals into a displayable RPM value. The faster the engine speed, the more pulses the ignition coil generates, and the higher the RPM value displayed on the gauge.

After driving the Baojun 310W for over a year, I've found the onboard fuel consumption display to be quite useful but shouldn't be taken too literally. During highway driving, it showed 5.8L/100km while actual fuel calculations came out around 6.3L/100km - a reasonable margin of error. This small-displacement car's display logic tends to be conservative. When accelerating aggressively, the display might spike to 8L/100km, but gentle driving can actually keep it just over 6L/100km. I recommend using a mobile app to track real fuel consumption. My routine is resetting the trip meter at each full refuel - over three months, I noticed the display averages 0.4-0.6L/100km lower than actual, with slightly larger discrepancies during frequent cold starts in winter.

Over the years working at the auto repair shop, I've handled quite a few Baojun 310Ws. The factory fuel consumption gauge calculates based on ECU fuel injection volume, showing minimal error in urban commuting. However, vehicles with severe carbon buildup will display increasingly inaccurate readings. I've seen a car showing 7.2L actually consume 8.6L, with the error reducing to 0.3L after throttle body cleaning. The instrument cluster's LCD screen has limited precision, displaying a 0.2L delay when values change. Special attention is needed for modified tire sizes - one customer experienced 6.8L displayed versus 7.9L actual after installing wider tires, due to mismatched wheel speed signals with the ECU.

When I first bought the used 310W, I specifically tested the fuel consumption accuracy. Filling up with 200 RMB worth of 95-octane gasoline allowed me to drive 362 kilometers, with the dashboard showing an average of 6.1L/100km, while the actual calculation came out to 6.7L. The error margin is smaller in suburban areas with fewer traffic lights, but in the city, the error can reach up to 15%. The displayed value is most inaccurate when the engine is cold. During summer, with the air conditioning on and stuck in traffic, the dashboard reading can spike to 9L while the actual consumption is close to 10L. Once, while driving on mountain roads in low gear for an extended period, the instantaneous fuel consumption display was about 18% lower than the actual value.
