Story

This 2008 Chevrolet HHR has been radically reimagined as a mid-engine, all-wheel-drive time attack contender tailored for the brutal demands of Pikes Peak. Relocating the turbocharged V6 behind the driver enables a compact, aerodynamic silhouette featuring aggressively raked widebody arches and a deep front splitter with dive planes. The extensive aero package is topped off by a triple-element rear wing, while large sidepods house lateral radiators that ensure efficient cooling in high-altitude conditions.

The suspension geometry and stance are optimized for mixed-surface grip, running massive 335-section slicks to harness the increased downforce and power. Functional details like the carbon fiber vented hood with NACA ducts, roof-mounted air scoop, and extended rear hatch airflow channels demonstrate an integrated approach to heat management and aerodynamic efficiency. Finished in matte charcoal gray with subtle red highlights, this HHR melds street familiarity with relentless hill climb aggression.
