This race-prepped Hyundai Ioniq set an FIA-approved production-based hybrid vehicle land speed record at the Bonneville Salt Flats, with speeds peaking at over 257 km/h.

The record number however was 253.994 km/h, and was achieved thanks to the car's single-stage nitrous injection system and special aerodynamics upgrades.


Further powertrain modifications included the low-restriction intake and exhaust system with retained catalyst, the re-calibrated engine, transmission and hybrid ECU, having the air conditioning and ancillary accessories removed and of course the previously mentioned cockpit-controlled Nitrous Express single-stage direct-port nitrous injection with a stand-alone fuel system.

In terms of aero, Hyundai engineers worked on the front grille, underbody and even removed some interior components in order to make the car lighter. The suspension was also optimized, and lightweight aero wheels and wheel covers were added.


As for safety, the car featured a fully-integrated high-strength safety cage structure, a Sparco 6-point safety harness system, a racing seat, on-board fire suppression, battery disconnects and a parachute.
