Basically, when Lehman Brothers tanked in 2008, everyone panicked and shorted everything that hadn't gone under. Including Volkswagen, who were somehow hovering around €200 a share. People doubled down on their shorts expecting imminent gainz, just like GameStop. But then Porsche announced their massive holdings, and the market realised there weren't enough available shares to cover the short positions. Ensue panic, and massive price rises.
