In addition to the car model, there will also be some English letters on the rear part of the car, which most people will not pay too much attention to. Even if they pay attention, they don't know what the letters mean. Here, we've taken stock of the complete car label in the rear section of the car, so that when you look at the rear of different vehicles, you'll know exactly what's written on the back of them, which generally has to do with the engine. A complete guide to car rear markings

1. FSI

FSI is the English abbreviation of fuel stratified injection. Compared with traditional engines that inject fuel into the intake manifold, the main advantages of FSI engines are: good dynamic response, simultaneous increase in power and torque, and reduced fuel consumption.

2. TFSI

TFSI is Audi’s patented technology and is developed based on FSI technology. It refers to “in-cylinder injection stratified combustion turbocharged engine”. Because stratified combustion technology must rely on in-cylinder direct injection, it can be referred to as a "stratified combustion turbocharged engine". The difference from FSI is the "T", which means turbocharging.

3. Technical Safety Index

TSI is the abbreviation of TurboFSI. t stands for turbocharging, S stands for supercharging, and I stands for stratified direct injection. This technology is very advanced, but after entering China, it was emasculated by supercharging and stratified combustion, leaving only turbocharging and direct injection. Different colors of TSI logos will appear on Volkswagen models, representing the same technology and different displacements. For example: I is red, representing a 1.4T engine; SI is red, representing a 1.8 engine; TSI is all red, representing a 2.0T engine.

4. TDI

TDI is the English abbreviation of Turbo Direct Injection, which means turbocharged direct injection (diesel engine). Compared with other engines, it has the advantages of high efficiency and low pollution. With gas prices soaring, diesel cars are a good choice. Many car manufacturers also produce diesel engine models when producing the same car, which is more popular in Europe and the United States.

5. CGI/CDI

Engine CGI technology is a gasoline direct injection stratified combustion lean combustion turbocharging technology. It is a patented technology of Mercedes-Benz. Its effect is actually similar to that of Volkswagen TSI. , but the implementation methods are different, and CDI is the diesel version of this technology.

6. T type or turbocharged

The full name of T is Turbo, which means turbocharged, which means that the engine used in this car is a turbocharged engine.

7. Liter

"L" has two meanings, one is the lengthened wheelbase L (long), the other is the engine displacement unit L (liter), and the wheelbase Extension is very common in Audi cars, such as Audi A4L, A6L, etc.

8. Li

Li is BMW’s special rear end, L is the extended wheelbase, and I is the electronic injection technology first adopted by BMW engines in the 1980s.

9. S or RS

Any cars marked with S or RS on the rear are high-performance cars. s is the abbreviation of Sport, which means movement. Usually these cars are equipped with QUATTRO four-wheel drive and suspension brakes, which change and improve the appearance and interior compared to ordinary cars. rs is the English abbreviation of racingsport, which means racing, so the RS car is taller than the S car.

10. AMG

AMG is the official modification factory of Mercedes-Benz. All vehicles equipped with AMG are modified models, with their own unique modifications from engines to appearance. At the same time, they also provide modification kits, various aluminum alloy wheels, front and rear bumpers, fog lights, etc. Basically, AMG modified models have become representatives of high-performance cars, and their technology is world-leading, especially in the modification of high-horsepower engines.

11. GT

GT is called a super sports car with high horsepower power output and two-door roof design (a convertible sports car cannot be regarded as a GT racing car), so the Chinese name of GT should probably be It is the world's top supercar.
