The Porsche Taycan will be the automaker's first official battery-electric sedan. Claimed to be a loose translation of "lively young horse," Taycan isn't pronounced like the Liam Neeson movie franchise, but instead tie-con.
Taycan keeps true to Porsche's tradition of using names that people will mispronounce more than a few times before getting it right.
