Although the night vision device of Mercedes-Benz BMW looks high-tech, it is not. Audi's high technology is tangible. ASF: All-aluminum body frame structure, only one, no branches. Significantly reduce the body weight and fuel consumption. FSI: In-cylinder direct fuel injection technology improves power and greatly improves fuel utilization. TDI: Turbocharged direct injection diesel engines have changed the world's concept of traditional diesel engines, and Audi's efforts have made diesel vehicles popular. At the same time, the advent of R 10 TDI once again proved that diesel is dynamic, fuel-efficient and efficient. Multimedia entertainment interactive system. Although Mercedes-Benz and BMW have similar systems, MMI is the best in the industry. Because of its humanized interface and friendly operation, complicated operation is simplified, and high integration makes the carriage look more concise and atmospheric. Quattro: Full-time four-wheel drive system, which is the essence of Audi and the embodiment of Audi spirit. Audi created quattro, and quattro made Audi. With quattro, Audi is not only the ever-victorious general of WRC, but also the first female champion of the world rally championship in history. Quattro is more and more accepted by everyone because of its excellent performance, not only in the field of sports, but also in the field of civil vehicles. Tiptronic: Manual/automatic integrated gearbox, very high-tech gearbox, almost no frustration when shifting gears. Very smart in d, s or manual mode. It can effectively reduce fuel consumption, protect the gearbox from frequent gear shifting and reduce gearbox wear. Multitronic: CVT, Audi's unique Multitronic CVT is one of its symbols in the gearbox field. Because of its toxic design and structure, Multitronic can not only drive the engine with large displacement and high torque, but also always match the number of revolutions of the engine without slipping. Multitronic can always ensure that there is no impact when shifting gears, and combined with manual mode, you can get a different driving experience. Because of its unique control structure, it is more fuel-efficient than manual gearbox in most cases. R-tronic: Sorry, I don't know much about it either. All I know is that it is used on R8, which has a lot to do with Lamborghini's Egear. The above examples are just the tip of the iceberg, and there are many advanced technologies such as advanced parking systems, solar skylights, adjustable air suspension systems and so on. Alas, Audi's slogan is "breaking through technology and enlightening the future".
