Hypermiler drivers Kevin Booker and Sam Clarke have broken the Guinness World Records title for the longest journey, of 916.74 km, by an electric car on a single charge. They achieved this record in a Ford Mustang Mach-E sports utility vehicle (SUV) fitted with Bridgestone tyres.

The electric vehicle (EV), the Mach-E Premium Extended Range SUV rear-wheel drive automatic, equipped with 18” wheels, a 91 kWh battery and boasting a range of 600.28 km, surpassed expectations, averaging 10.05 km/kWh on public roads throughout Norfolk, Lincolnshire, Yorkshire, Nottinghamshire, Leicestershire and Cambridgeshire, in England.

The drive, completed over 24 hours, included a mix of urban and rural roads to emulate real-world driving conditions. The record attempt was meticulously documented with independently verified video footage, odometer readings, GPS and battery level data from Bridgestone's fleet management solution Webfleet.

Booker and Clarke were supported by Webfleet co-pilot Richard Parker.

Bridgestone tyres were seen as a critical component in the world record attempt, offering outstanding mileage and low rolling resistance, says Bridgestone Mobility Solutions Webfleet UKI regional director Beverley Wise.

“This record is a testament to the hard work and dedication of everyone involved in this endeavour,” she adds.

The journey represents a significant milestone in the electrification of road transport and demonstrates the potential of EVs, when supported by innovative Bridgestone tyre design and advanced fleet management technology, Booker says.

“Breaking this record has been an exhilarating journey and a powerful demonstration of what EVs can achieve. It is incredible to see how far we have come with EV technology and efficiency. We hope this inspires more people to consider EVs for their everyday travel,” he says.

“Driving the Ford Mustang Mach-E for such a distance on a single charge was an extraordinary experience. The vehicle's efficiency and the support from Webfleet’s technology made this possible,” Clarke adds.

“We are delighted to have supported this incredible achievement with our expert patrols and backup team. The drivers, together with Ford Mustang Mach-E, Bridgestone and Webfleet, have all used their expertise to prove that EVs can go much further than people think. Such endeavours are important to show that EVs can be a major part of the future transport mix,” says UK roadside assistance organisation AA president Edmund King.

The AA in the UK provided official adjudication and its EV support services for the record attempt.

Meanwhile, Clarke and Booker both hold previous records for fuel economy and energy consumption in EVs. Clarke has now amassed five and Booker two driving-related Guinness World Records titles.
