Does an electric car consume more in Europe than in China?

Have you noticed that the technical specifications of cars sold in China are always much better than before their arrival in Europe?

The range of electric cars often appears to be greater in China than in Europe, and this is largely due to the calculation methods used. In China, the CLTC protocol is used, whereas in Europe, the WLTP is the standard. Both standards significantly impact the figures published by manufacturers.

CLTC: Chinese Optimism

The CLTC cycle (China Light-Duty Vehicle Test Cycle) is designed to reflect local driving styles, which are mostly urban and peri-urban, with low-speed trips. The test favors calm driving periods, with few harsh brakes and moderate accelerations. These conditions, gentler on the motor and battery, allow for higher reported ranges.

For example, the average speed during CLTC tests is 30 km/h, with a maximum speed of 114 km/h. These idealized figures underestimate actual energy consumption, providing a somewhat overly optimistic picture of electric vehicle capabilities.

WLTP: European Realism

In Europe, the WLTP protocol (Worldwide Harmonized Light Vehicles Test Procedure) is much more representative of real-world conditions. Tests include urban, peri-urban, and highway trips, with an average speed of 46.5 km/h and peaks at 131 km/h. This demanding cycle better aligns with European driving conditions, especially on highways where fuel consumption is higher.

The results from CLTC are often 10 to 20% higher than those obtained with WLTP. That is why electric cars in China seem to have a greater range.

Ultimately, this difference is not just about technology or driving habits, but also depends on the calculation method, which in China emphasizes more optimistic figures, whereas in Europe, a more realistic approach is maintained.
