I'm not sure how much will be built by the time I visit the Stuttgart HQ in May to record a 'This week in Cleantech' podcast. Not much I expect, but having seen Audi suffer eTron delays due to battery supply it's vital major OEM's secure supplies, or of course build their own. Like Tesla I'd recommend the latter as the best option. Auto OEM's certainly know how to manage a supply chain, and build volume solutions, I don't see any issues with them rising to the battery challenge, materials aside.
Daimler company Mercedes Benz Cars has now begun construction work on the planned battery sub-plant on its Brühl site situated at the company’s home grounds in the Stuttgart district of Untertürkheim. Batteries for future electric vehicles of the EQ family will soon be assembled on an area of 12,000 square meters. The sub-plant is to be inaugurated as part of Mercedes-Benz’s own global battery production network. “The laying of the foundation stone (…) is a good signal for the sustainability of mobility and a commitment to the location,” says Daimler CEO Dieter Zetsche. “Battery factory at the Brühl sub-plant stands for our promise to make both our cars as well as their production even greener. In future, we will assemble the heart of the electric car – the battery – here ourselves”
