Pronounced tie-con, the name is said to be traced to a word for a "lively young horse."
Porsche has announced that its Mission E will be sold under a different name as the Taycan.
The term -- pronounced tie-con not tey-kuhn -- is said to be roughly translated as "lively young horse" in reference to the imagery at the heart of the Porsche crest.
"Our new electric sports car is strong and dependable; it's a vehicle that can consistently cover long distances and that epitomises freedom," says Porsche chief Oliver Blume.
The performance marque's first all-electric production car boasts an output of over 600 horsepower via dual permanent magnet synchronous motors (PSM) and an 800-volt battery system. The car is expected to launch from zero to 62 mph in under 3.5 seconds and up to 124 mph in under 12 seconds.
Porsche has billed the Taycan as a track-capable EV, designed to support multiple jump starts in quick succession without power loss due to battery overheating.
