Completely independent engines, the 2.5L and 3.0L engines carried by Hongqi H7 are completely different from Toyota V6 engine in cylinder bore, stroke and compression ratio. In addition, the included angle between two cylinders of Hongqi V6 engine is 90, while the included angle between two cylinders of Toyota Crown V6 engine is 60, which shows that the two engines are even different in basic structure. To put it bluntly, they are two completely different engines without any blood relationship. So the myth that "H7 uses the crown engine" can end here.
2.0T model, I believe this car has the most reference significance for consumers who plan to buy Hongqi H7, after all, the price is relatively cheap. The match is TD04 turbocharger made in Zhong Ling (Audi's 2.0T uses K03 turbocharger from Borgwarner, which is totally different). Zhong Ling's technology and manufacturing process come from Mitsubishi Heavy Industries, which is a world-renowned turbocharger manufacturer.
