2021 Porsche Taycan breaks electric vehicle records

13 British endurance records. The Porsche Taycan now lays claim to having driven 1000kms in 13 hours at the Brands Hatch racing circuit in the UK, taking the record in the category of electric vehicles (EVs) over 1000kg . Of the 13 records, Porsche set the quickest EV to reach 50km, 50 miles, 100km, and 500km marks from a standstill – among others – as well as the 1000km distance record. Brands Hatch was the location of choice, with the German manufacturer having claimed various endurance trophies at the track. In fact, Porsche made up the first six places during a 1000km race in 1984. To assist with the task, a star-studded line-up of drivers took to the wheel of a Taycan Turbo S and Taycan 45, with all cars were exhibiting tribute liveries to celebrate the success of Porsche at the historical circuit.
