Some time ago, the professor wrote an article about the top ten power systems of Ward in 2022, which caused controversy among many netizens, among which everyone asked more: Why is the power system developed by independent brands not on the list? Regarding this question, it is mainly because the Ward Top Ten power systems only count vehicles sold in the United States, and domestic self-owned brand models basically have no status in the US market, and even have no sales channels, so it is natural not to be on the list.
The United States has the top ten power systems of Ward, in fact, there are also in China, that is, the "Chinese heart" annual top ten power systems. It is worth mentioning that the "Heart of China" annual top ten engine selection has a history of 14 years, the selection agency focuses on the market performance of the engine and the effect of energy saving and emission reduction, and the expert jury suitable for China's national conditions participates in the selection, which is more in line with the domestic consumers' car standards, with strong fairness and persuasiveness.
