Shares of electric car maker Tesla Motors (TSLA) plunged $5.46, or 19%, to $22.79, late in today’s session but regained 7% in late trading after the company said its head of engineering, Peter Rawlinson, for chief of chassis engineering for its “Model S” line, Nick Sampson, quit, as related by Bloomberg’s Alan Ohnsman.
Rawlinson departed to attend to personal matters, the company said, and Sampson is said to have “transitioned” away from working on the Model S, Ohnsman notes.
