Advantages: Just like the advertising words of a brand of German cars, "breaking through technology" is what German cars often do. Many new technologies originated from German cars or were first applied to the market by German cars. For example, high-pressure rail technology, high-precision in-cylinder direct injection technology, turbocharging technology, full-time four-wheel drive technology, 8AT, DSG and so on. Germans are famous for their preciseness, and their cars are even better in workmanship. As we all know, German expressways do not limit the maximum speed of vehicles, and the north-south span of Germany is large, so the high-speed driving stability of small and medium-sized cars and above in Germany is better and the maximum speed of vehicles is higher.
