Hillclimb Harrier

The Hillclimb Harrier transforms the 1983 Chrysler Fifth Avenue from a classic American luxury cruiser into a ruthless hill climb contender. This build strips away the sedan’s traditional comfort, integrating a front-midmounted 5.2L turbocharged V8 beneath a vented carbon fiber hood, paired with a clam-shell polycarbonate rear hatch for optimized heat extraction. Its widebody stance, enhanced by over 600mm of track width gain and sharply sculpted arch extensions with vortex generators, combines aggressive aerodynamics with the sedan’s imposing silhouette to maximize grip and airflow control on steep, twisty ascents.

Purpose-built for privateer competition, the Harrier features a triple-element carbon wing with hydraulic height adjustment and an extended front splitter, emphasizing downforce and balance rarely seen in this chassis class. Adjustable suspension lowers the car to just 110mm ride height, while Centerlock OZ Racing wheels wrapped in Michelin Pilot Sport Cup 2 tires ensure traction and responsiveness. This build is a technical statement—a collision of 1980s turbo era muscle and modern carbon aero refinement, designed to dominate tight, demanding hill climb courses with poise and precision.
