Wei Jianjun criticized that the 2-liter fuel consumption promotion is divorced from real usage scenarios. "Is it meaningful to have low-resistance tires on a downhill with tailwind?"

In recent days, at the 1000th internal whole-vehicle quality review meeting, Wei Jianjun, chairman of Great Wall Motors, expressed his views on the current phenomenon of promoting hybrid models with "2L fuel consumption". He stated that such data is often measured under ideal conditions such as low resistance tires, specific slopes, and tailwinds, which deviates from the real-world usage scenarios of users and is essentially parameter foam. "2L fuel consumption" typically refers to a comprehensive fuel consumption of about 2 liters per hundred kilometers, which is claimed by plug-in hybrid or some high-efficiency hybrid models to have extremely low fuel consumption levels.
