The clock is ticking towards the official unveiling of Porsche's 1st all-electric sports car, the Taycan
to 124 miles per hour , often in 10 seconds, one after the other, at a test track. The Porsche did not appear to be sweating the repeated sprints.In another demanding test, this time for the battery pack and electrical system, Porsche lapped the famous Nardo circuit for a full 24 hours at speeds between 120 and 135 miles an hour . When the car's battery was close to empty, it was hooked up to a 250-kilowatt, juiced back up and returned to the track. Wash, rinse, repeat.
It's a bold choice seeing how most of the thinking on electrically-powered vehicles' power transmission systems usually follows the mantra of"simple is better," as in there's really no need for gearing given an electric motor's ability to make massive torque from a standstill, and then hold that output over an extremely wide RPM range, something gas engines just can't do.
The other big call Porsche made was with the battery, power control and charging systems. The Taycan will use liquid-cooled motors as well as a liquid-cooled 800-volt battery pack and charging system, with a typical battery coming in at 90kWh of capacity, close to Tesla's 100kWh pack option.
