Hyundai’s Ioniq has set a new FIA-approved hybrid land speed record at the Bonneville Salt Flats with the help of nitrous.

Fans of Fast and Furious will no doubt be familiar with the nitrous bottle, a tank designed to hold the N2O pressurised in liquid form. When injected into an engine, more oxygen becomes readily available during combustion allowing for more fuel to be added, thus increasing the amount of power the engine generates.

To push the Ioniq to its limit, Hyundai’s Engineering and Quality team boosted the engine’s power output by remapping the ECU and adding low-restriction intake and exhaust systems. To make space for the nitrous injection system from Nitrous Express, the hybrid’s air conditioning system and secondary accessories were removed.

Other changes made includes swapping out the hybrid grille for the EV’s, modified underbody and air dam, removed unnecessary interior components, lowered the ride height with Progress Competition coil-over suspension, and a set of aero wheels wrapped in Goodyear Eagle tires. Of course a safety cage, racing seat, six-point harness, and fire suppression system was added for the driver’s safety.

An exact horsepower figure was not provided, but it did managed to hit 157.825-mph on the salt flats and the Ioniq Hybrid had a peak exit speed of 160.7 mph.

For everyone else, the production Ioniq Hybrid should go on sale later this year.

one thing this does point out to me is how strong and well engineered the whole drive train is

they don't say they had to replace the clutch packs in the DSG gearbox so the gearbox can handle far more torque than the production engine can throw at it, not even replacing the cams or valves in the head so the lower power of the Atkinson cycle engine seems to have been blown out the water as well :)

this was a stock engine and gearbox with just new inlet pipework, exhaust, nitrous and a remap

that is pretty impressive for a new engine,

but nice as it is, it does sort of goes against the ECO credentials of the car, but I did notice the exhaust "retained cat" :)

final question is "could the stock Prius engine and CVT handle similar power levels without breaking"?
