BMW is ramping up its electrification plans with confirmation that it will introduce a new design of battery cell on its next generation of electric cars. The German brand is set to launch cars based on what it calls ‘Neue Klasse’ (New Class) framework. 

The newly-developed sixth generation of lithium-ion cells feature an energy density increase of more than 20 percent, improved charging speed by up to 30 percent and range improvement of up to 30 percent. 

The new round cells are also expected to be cheaper to produce thanks to a move to shorten the supply chain of packs. BMW has already awarded multi-billion Euro production contracts for the new cells and plans to introduce them in 2025. Based on current market assumptions, BMW estimates that costs can be reduced by up to 50 percent, compared to the current fifth generation cells. 

The brand also claims that the new production process will reduce its CO2 emissions by up to 60%. The new cells will be built at six new locations, two in China, two in Europe and two in America. Each plant will have an annual capacity of up to 20 GWh. Commenting on the new facilities,  Joachim Post, member of the Board of Management of BMW AG responsible for Purchasing and Supplier Network. “We have also reached agreement with our partners that they will use a percentage of secondary material for the raw materials lithium, cobalt and nickel, as well as utilising green power for production, to ensure CO₂-reduced manufacturing.”

The ‘New Class’ introduces a new approach to building cars. Where current models like the i4 and iX3 are internal combustion engine cars that can accommodate electric drive systems, the New Class models will based on an electric platform that can also accommodate internal combustion engines. The shift in emphasis will allow BMW to maximise cabin space and allow for larger packs to be installed. 

The first New Class models are expected to be a replacement for the current 3-Series (aimed at the Tesla Model 3) and a compact SUV that will be pitched against the Tesla Model Y. Both are expected to launch in 2025. 

First BMW Neue Klasse model is expected to be a saloon that will go head-to-head with the Tesla Model 3
