Hyundai Ioniq sets hybrid speed record

A Hyundai engineering team modified an Ioniq hybrid to set a speed record of 157.825 mph at Bonneville.

  • Ioniq

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 157.825 mph, with a peak exit speed of 160.7 mph 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 late 2016.

“A key role of Hyundai’s engineering team is to thoroughly test all future vehicle prototypes to ensure they exceed the demanding expectations of our customers,” said Mircea Gradu, director, Engineering and Quality, Hyundai Motor America.

“As we performed these tests on Ioniq, the engineering and quality staff became so impressed with the results that we began to wonder if we should raise our sights even higher, and the Ioniq land speed record effort was born.”
