Race-prepped Hyundai Ioniq Hits 254km/h on Bonneville Salt Flats

A race-prepared Hyundai Ioniq hybrid prototype, developed by Hyundai Motor America’s Engineering and Quality team, set an FIA-approved production-based hybrid vehicle land speed record of 254km/h, with a peak exit speed of 258.6km/h at Utah’s renowned Bonneville Salt Flats. The eco-focused Ioniq is Hyundai’s newest hybrid model, with hybrid, plug-in hybrid and electric powertrains to be available. Ioniq hybrid and electric models go on sale in the U.S. in late 2016.
