Launched in 1989, Lexus LS400 is the work of Toyota determination to conquer the world's luxury saloon market. With the famous car quietness, driving comfort, and the Japanese car factory's craftsmanship, everyone has a lot of love for the Lexus brand from the beginning. It was only a short period of time, people doubted that the LS400 as a rival of its German counterparts, and finally recognised the LS400 as a premium luxury car brand. Infiniti's approach is similar to that of Lexus, both hoping to use another brand to establish a more upscale image than Nissan. The Q45, which was launched at the same time as the LS400, also uses a V8 engine. Its body size and cabin equipment are comparable to those of the LS400. However, the final record of the Q45 is not as brilliant as the LS400. What is the reason? In this video, Edmond and Lung Sir test-drive the Lexus LS400 and Infiniti Q45 to see the pros and cons of two classic Japanese luxury RVs in the 1980s and 1990s, and look back at the meaning of V8 RVs.
