Hillclimb Rocket takes the 2022 Hyundai Elantra’s clean sedan silhouette and turns it into a purpose-built aero car—wide, low, and honest about what it’s for. The track is pushed to 1800mm up front and 1770mm rear with vented overfenders that relieve wheel-well pressure, while a 150mm extended nose and twin intercooler apertures keep charge temps stable when the road climbs and the air thins.
Out back, the story is downforce you can tune: a 2200mm electronically adjustable wing paired to an undercut diffuser that works with a sealed floor. It’s a modern hillclimb approach—big grip, big stability, and cooling that doesn’t blink—wrapped in a race-team-clean execution that still reads like an Elantra at first glance.
