An ambitious electric vehicle plan is under way, with 30 electric models expected to be sold by 2025, including 20 new and 10 new vehicles. At that time, Audi hopes that the annual output of these 30 electric vehicle models will be about 800000, accounting for 40% of the global sales, and helping Audi reduce carbon emissions by 30% (compared with 2015). In fact, it is not easy to launch 30 new electric vehicles in such a short period of time. Audi claims that it has invested about 12 billion euros in the development of new electric vehicles around the world, which will be realized by supporting four different platforms of various power assemblies, including MLB Evo, MEB, and j1and PPE jointly developed with the group. First of all, I will introduce the MLB Evo architecture. This is the first platform used by Audi's new generation of electric vehicles, and it has been determined to build the current e-tron and the upcoming e-tron s Sportback. MLB Evo is from the Volkswagen Group, which is not only used by many electric vehicles to build Volkswagen brand, including current, A4, A5, A6, a7, A8, Q5 and Q8, but also used by the Lamborghini urus and Porsche Cayenne. The j1architecture jointly developed with Porsche is the second platform to support many new Audi cars. The first product of the platform is the Porsche taycan sports car. Next is the Audi e-tron GT performance car mass production version. The concept version is equipped with two motors, with the maximum output of 582 horsepower and 829 nm respectively. The reason why the j1platform is different is that it supports 800V system and can realize super fast charging. In fact, the Audi e-tron GT can be charged to 80% in only 20 minutes. Next is the MEB platform. Like MLB Evo, MEB platform also borrows from Volkswagen Group and will be applied to many models of Volkswagen Group in the future. However, unlike MLB Evo, which supports internal combustion engine power, MEB only supports electric power assembly. As a smaller platform, it will be used with entry-level electric vehicles in Audi's lineup, similar to MQB platform (Audi is now used for smaller gasoline / diesel powered vehicles). The first product of Audi MEB platform will be the upcoming Q4 e-tron, while the products of Volkswagen brand include id.3, id.4 and ID. Buzz and ID. Vizzion。 PPE (premium platform electric) is the fourth and last platform to support the future Audi electric vehicle. Like the j1platform, PPE is jointly developed by Audi and Porsche, which can be used in medium-sized and large-scale electric vehicles. It supports SUVs with high and low body, sportbacks, avant travel vehicles and cross-border vehicles, and its application range includes A4 to A8 and Q5 to Q8. The platform supports an 800 volt electrical architecture with a charging rate of up to 350 kW, but it is not clear whether it will be used by other models of the Volkswagen Group in the future. Under the impact of coronavirus, all parts of the world are faced with general shutdown and social isolation. Audi chooses to provide online technical lectures at this time to introduce the work of Audi's electrification in the next five years in detail, which will help to further promote the faster marketization of electric vehicles.
