Hyundai’s Kona Electric achieved a ‘real-world’ range of 259 miles on a single charge during a What Car? Real Range test – the highest of any vehicle tested.

The compact SUV, which Hyundai says has a range of up to 300 miles, was one of 13 electric cars tested, with the brand’s Ioniq achieving the highest energy efficiency and lowest cost per mile.

It covered 3.9 miles per kWh – 11% further than any model from a rival brand. It achieved a real-world range of 117 miles. Hyundai says its range is 174 miles.

Tony Whitehorn, president and CEO of Hyundai Motor UK, said: “The results of the What Car? Real Range tests are a terrific endorsement of our zero-emissions models.

“Achieving not only the highest ‘real-world’ driving range, but also the best efficiency and lowest cost-per-mile figure of any brand is testament to our commitment to reducing the environmental impact of our vehicles.

“These cars are a compelling proposition for both fleet and retail customers, and we’re confident that Kona Electric and Ioniq Electric will continue to attract praise from media and motorists alike.”

The analysis as carried out at Millbrook Proving Ground and incorporates a mix of town, A-road and motorway driving conditions.

Testing is done with the lights on, climate control set to 22 degrees and in an ambient temperature of between 10 and 15 degrees.
