On Thursday, Hyundai Motor said it will launch a long-range electric vehicle with a driving range of 500 km (311 miles) per charge after 2021. The company is reportedly planning 31 eco-friendly models by 2020, up from a previously flagged 28. Reuters reports: The South Korean automaker is planning to launch an electric sedan under its high-end Genesis brand in 2021 with a range of 500 km (310 miles) per charge. It will also introduce an electric version of its Kona small sport utility vehicle (SUV) with a range of 390 km in the first half of next year. The automaker and affiliate Kia Motors Corp, which together rank fifth in global vehicle sales, also said they were adding three plug-in vehicles to their plans for eco-friendly cars, bringing the total to 31 models by 2020. Underscoring Hyundai's electric shift, those plans include eight battery-powered and two fuel-cell vehicles -- a contrast to its 2014 announcement for 22 models, of which only two were slated to be battery-powered. Hyundai also confirmed a Reuters report that it is developing its first dedicated electric vehicle platform, which will allow the company to produce multiple models with longer driving ranges.
