MEB electric platform-representative model: Audi Q4 e-tron concept car
MEB platform everyone is familiar with, this is a heavy gold for Volkswagen The developed platform for pure electric vehicles can realize modular design and launch electric vehicles with different cruising range. ID 3 based on this platform has been unveiled at this year's Frankfurt Motor Show.
What is the relationship between Audi and MEB platform? Audi is a platform under the Volkswagen Group. Audi and Volkswagen collaborate to share the MEB platform. In the future, some of Audi's entry-level and affordable electric vehicles will be built on the MEB platform. Platform sharing is already a trend. Before, Volkswagen MQB platform was also shared by Volkswagen and Audi.
According to Audi, the MEB platform provides the technical foundation for Audi’s future compact and mid-level models, becoming Audi’s entry-level electric vehicle platform. Using the MEB platform shared by the Volkswagen Group, Audi can provide customers with relatively low-priced, but technologically advanced electric vehicles with distinctive Audi DNA, including attractive designs, high-quality interior workmanship, and top operating systems. Specific models include SUVs, crossovers, cars, etc.
The Q4 e-tron concept car, which is close to mass production, is built on the MEB platform. This is the first mass-produced Audi car based on the MEB platform. The exterior dimensions of the Q4 e-tron concept car are the same as those of the Q3, and the interior dimensions are the same as those of the Q5. Its 4.59-meter body length is at the level of an A-class car; however, thanks to the 2.76-meter wheelbase, its interior space is comparable to a mid-class car. As we all know, because of the elimination of the internal combustion engine powertrain, each MEB model is one level higher than the traditional models in terms of interior length.
MEB platform is characterized by flexibility. Therefore, Audi electric vehicles built on this platform can provide a variety of models with different performance configurations and drive forms for users to choose. In addition to the typical quattro full-time four-wheel drive system, there are also entry-level rear-wheel drive models.
