In order to reduce carbon dioxide emissions and meet the more stringent regulatory requirements of the EU in 2020, a series of cars are being added. At the same time, both companies said the introduction of more plug-in hybrids would help reduce carbon emissions by 20% by 2020. According to LMC automotive, a well-known automobile consulting company, the sales volume of plug-in hybrid vehicles in Europe will exceed in 2020, among which the sales volume of PHEVs will increase from 198853 in 2019 to 717000 in 2020, accounting for 4% of the European market share. Meanwhile, the registered volume of pure electric vehicles will increase from 365372 in 2019 to 652000, with a market share of 3.6%. Some analysts believe that BMW and Mercedes Benz (as well as other brands) are technically backward from electric vehicles to plug-in hybrids. In fact, the two manufacturers made such a choice from the EU's "super carbon credits" system. According to EU regulations, plug-in hybrid vehicles with carbon dioxide emissions less than 50g / km can be used to offset the emissions of other vehicles, and the super carbon credits of plug-in hybrid vehicles will be reduced by 2023. According to FEV, a technology company based in Aachen, Germany, the plug-in hybrid car group needs to be large enough to get super carbon credits, and its manufacturing cost is higher than that of a small electric vehicle with a 32 kwh battery pack. However, plug-in hybrids are easier to sell than pure electric vehicles, and car manufacturers have calculated that the added cost of plug-in hybrids is less than the penalty they face. Boan, a leading London based consultancy, said that if Mercedes Benz and BMW did not reduce their current emissions, they would face a fine of 997 million euros (7.66 billion yuan) and 754 million euros (5.8 billion yuan) respectively. Mercedes Benz has added plug-in hybrids to its lineup of C-class intermediate sedans, E-class intermediate and senior sedans and travel models. In Europe, the smaller Mercedes Benz A-class and B-class also use plug-in hybrid drive systems. By the end of 2020, as many as 20 Mercedes Benz plug-in hybrid models are expected to be on sale. Among them, Mercedes Benz a 250E car is equipped with a 1.3-liter gasoline engine, 75 kW motor and 15.6 kwh battery pack. Its carbon dioxide emission is about 32 g / km. It takes only 25 minutes to charge the battery pack from 10% to 80% through DC fast charging. Mercedes Benz E-class provides 7 plug-in hybrid models, covering a variety of gasoline, diesel engines and battery power systems. At the same time, BMW has extended the 3-Series plug-in hybrid to the travel version, whether it is a two-wheel or four-wheel drive version. In addition, BMW has 330E plug-in hybrid four-wheel drive cars and plug-in hybrid X1 and X2 models. The capacity of the battery pack of the BMW 3 Series plug-in hybrid car will be increased from 7.2kwh to 12kwh, so as to achieve a pure electric range of 40km, almost double. A month ago, Ola K ä llenius, Daimler's chief executive, acknowledged that meeting Europe's stricter emissions targets for 2020 and 2021 would be a challenge. It is clear that Daimler, the parent company of Mercedes Benz, is tackling this challenge by adding more plug-in hybrids as well as conventional hybrids, including light hybrids. "We are not far from reaching our goals. By the end of 2020, we hope to double the sales of light hybrid vehicles and triple the market share of plug-in hybrid vehicles. " Kalenius said. Unlike Mercedes Benz and GM, which are building dedicated platforms and factories for electric vehicles, BMW is looking to use flexible manufacturing processes to produce pure electric vehicles, plug-in hybrid vehicles and internal combustion engines on the same assembly line. Some analysts believe that, in any case, BMW and Mercedes Benz choose to switch from plug-in hybrid system, which shows that they have no urgent pursuit for pure electric vehicles, nor special ideas. Only in order to comply with legal requirements and regulatory constraints, they adjust business and market decisions. Otherwise, they will wait until the battery price drops to a certain extent, or until 2023, when the plug-in hybrid car super carbon credit is cancelled.
