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.
The development team made a number of special modifications to the Ioniq hybrid prototype to break the hybrid record, including:
Powertrain
- Low-restriction intake and exhaust systems with retained catalyst
- Engine, transmission, and hybrid ECU recalibrated and governors removed
- Air conditioning and ancillary accessories removed
- Nitrous Express single-stage direct-port nitrous injection with stand-alone fuel system, cockpit-controlled
Aerodynamics/Weight Reduction
- Ioniq Electric model front grille and valance integration
- Underbody and air dam aerodynamic modifications
- Interior components removed or lightened
Suspension
- Progress Competition coil-over suspension with optimized spring, damping and sway bar rates and ride height lowered 100mm
- Lightweight aero wheels and wheel covers with Goodyear® Eagle tires
Safety
- Fully-integrated high-strength safety cage structure (Bisimoto-designed)
- Sparco® 6-point safety harness system, racing seat, and driver safety gear
- On-board fire-suppression system, battery disconnects and parachute
