Let me popularize this knowledge point, which is an extension of the classic three-color bar logo of BMW M series. For example, in addition to the ordinary 3 Series, BMW also has a M3 version, which is a violent driving machine with a 3 Series shell, a 3.0T six-cylinder engine, and a zero-speed acceleration of 4.6S It is purely for the track, and it will be sold at 870,000 yuan. BMW specially set up this M department to build performance cars, and the logo of this M is made up of three colors: red, dark blue and light blue: light blue represents Bavaria, the headquarters of BMW, which is taken from the color of their state flag; the dark blue in the middle symbolizes the integration of BMW and Motorsport, and the red on the far right symbolizes motorsport, high performance and so on. This three-color bar on the front grille is an extension of the BMW M logo. It was originally exclusive to BMW M, but some ordinary BMW owners also put three-color bars on the front grille and the M mark on the rear butt in order to be cool. There are too many owners of BMW 3 Series disguised as M3. You should know that M3 is a million sports cars imported purely, while the rear butt of ordinary 3 Series is BMW Brilliance. However, changing M3 into a three-color bar will soon be seen through, at least it should be surrounded by changing sets. Other brands paste this three-color bar, which is purely pretentious. For example, the Buick is the easiest to change. Because the front grille is similar to BMW, it is symmetrical to paste it on both sides, and the identity immediately becomes noble, and the chicken immediately becomes a phoenix! Similar to BMW M Series, Mercedes-Benz AMG and Audi RS are all performance models. Similarly, some car owners have changed the ordinary version of Mercedes-Benz to AMG, which is a &”;vulgar&”; demand in the modification industry, so you should quit it, otherwise it will be easy to make people despise it. The above is the opinion of No.66 car review. Remember to like my answer and pay attention. Welcome to discuss and add.
