Epic Zero Carbon World road trip demonstrates battery longevity
Last weekend, members and supporters of Zero Carbon World, a charity promoting decarbonisation projects, drove an original 11-year-old Tesla Roadster from Land’s End to John O’Groats in order to demonstrate the longevity of older electric cars. The aim was also to give a practical demonstration that the often-heard myth of batteries lasting only a few years does not hold true.
The Tesla, originally belonging to
Zero Carbon World founder Kevin Sharpe, is the same car that completed the first ever John O’Groats to Land’s End trip by an electric car in 2011. On that occasion, Sharpe and co-driver David Peilow completed the challenge in 36 hours.
This time, however – ten years and 63,000 miles later – the car completed the trip in 21 hours and 27 minutes: more than 14 hours quicker. The Tesla Roadster has the same battery it left the factory with in 2010, and has been fitted with an off-the-shelf rapid charger socket from US supplier QC Charge, enabling it to use the improvements to the charging infrastructure installed during the intervening decade.
The car’s new owner, Zero Carbon World trustee Dean Fielding, set out to show that it was just as capable of doing the drive today as it was in 2011. Joined once again by Peilow, alongside experienced electric vehicle owners Glyn Hudson and Evan Tuer, the team took it in turns to drive the two-seat Tesla Roadster.
“Since I bought the car in 2018 it has been completely reliable, so I was confident that it could still do this trip without a problem. There is a pervasive myth that the batteries in these cars must be replaced every few years at great expense; a myth that has no basis in evidence,” said Fielding.
“What better way to dispel this idea than drive the car the length of the country for a second time? While there is some degradation of the battery over that lifetime, this achievement clearly demonstrates that this has no effect on being able to use the car every day and on long journeys.”
