In the inheritance of the traditional classification of traditional models on the basis of the chassis, powertrain and support technology almost all shared, according to different brand positioning different people, to create hardware technology is almost the same, and in software technology, appearance, space and adjustment And so on to make differentiated different models fit Audi A6 C5 Compressor. For example, for example, we are familiar with the PQ34 platform, it refers to the mass transit engine (PQ) compact vehicle (3) fourth generation (4) platform. This "first generation" is the number from the ABC platform era has been continued down. After the formal presentation of the platform fit Audi A6 Compressor, the public will be a formal focus on the design of the common parts of the road, and with the company's growth and versatility of the design is getting higher and higher, this design ideas have become increasingly integrated, Until recently, this extremely high degree of platform strategy and even break the model-level barriers, developed into a modular concept fit Audi Allroad Suspension Compressor. On the aspects of modularization we will say later, and now, let's take a look at the technical features of the famous platform of the public after Piech's formal presentation of platform.
