Not long ago, we explored the possibility of Audi taking out Tesla with its forthcoming brace of e-Tron electric sportscars. What we didn’t realize fully at the time, is how directly VW is going after Tesla. At a recent visit to Volkswagen’s Silicon Valley Electronic Research Lab though, I was shown the slide above, which represents the battery packs for the forthcoming e-Tron and e-Up EVs… and it suddenly hit me that Tesla founder Martin Eberhard was applying Tesla’s multi-cell strategy at Volkswagen, essentially duplicating Tesla’s work with the backing of a major OEM. Now, Eberhard is talking to Autocar, and he says that his Tesla-style multi-cell powerpacks could offer 500 miles of pure electric range within ten years. If he’s right, the other OEMs who are focusing on prismatic Li-ion cells are in for a rude surprise… and Tesla had better start making some progress.
