Platform 2019 Toyota C-HR
Era 2010s OEM+ / Instagram Era

The 2019 Toyota C-HR Hillclimb Juggernaut redefines what a crossover can be in the realm of unlimited hillclimb competition. Its massively widened bodywork extends track width to nearly two meters front and rear, providing an unshakable planted stance through the tight, elevation-heavy mountain roads. Every panel serves a purpose: sharply flared arches with integrated vortex generators, a carbon fiber hood with heat extractors, and a rear hatch transformed into a multi-element diffuser with a hydraulically actuated wing that dynamically adjusts up to 75 degrees for insane downforce levels. Beneath the aggressive aero, a race-spec 380hp turbocharged inline-four breathes through ram-air intakes, paired with adjustable coilovers set at a race-low 85mm ride height. The BBS LM forged wheels wrapped in Michelin Pilot Sport Cup 2 tires and extreme negative camber balance precision grip with aggressive cornering clearance. This build blends modern OEM crossover architecture with Pro Racing and Time Attack design cues, making it a true mountain pass monster with race team authenticity and carbon fiber craftsmanship visible in every detail.

Technical Dossier // R028

Track

Specifically tailored for demanding hillclimb courses, this build excels on rapid elevation changes and tight switchbacks. The expansive track width and ultra-low stance provide stability and confidence through corkscrew turns, while the advanced aero package generates significant downforce to keep the car planted on steep gradients. The setup shines in mountain environments where aerodynamic efficiency and mechanical grip are paramount.

Body Modifications

330mm front and 340mm rear widebody extensions
Sharply flared arches with integrated vortex generators
Full carbon fiber sculpted hood with heat extractors
Ultra-lightweight rear hatch converted into diffuser housing

Aero Components

Multi-element hydraulic rear wing adjustable up to 75°
Integrated side skirts engineered for ground effect
Front splitter extension with dive planes
Clear functional aero strakes on fenders

Aero

Every aerodynamic element is crafted for maximum downforce and flow control on mountain passes. The carbon fiber hood features three forward-facing heat extractors and ram-air intakes for efficient cooling and engine breathing. Side skirts employ ground effect principles, while clear aero strakes and dive planes optimize airflow over widened arches. The rear hatch converts into a multi-element diffuser housing a hydraulic rear wing capable of a 75° angle of attack, delivering exceptional vertical downforce on demand.

Wheel and Tire Setup

18x10" forged BBS LM wheels
Michelin Pilot Sport Cup 2 tires
Front -4° and rear -5° negative camber
Widened track: 1905mm front, 1920mm rear

Wheels

Mounted on 18x10" forged BBS LM centers, the wheels combine lightweight strength with race-proven design. Wrapped in Michelin Pilot Sport Cup 2 tires, the setup ensures optimal grip and feedback on both dry and slightly damp mountain surfaces. The wide track and negative camber geometry maximize tire contact patch during aggressive cornering, balancing durability and performance for hillclimb demands.

Stance

The Hillclimb Juggernaut presents an aggressive, purposeful stance defined by its extreme track widening and sharply negative camber. The ride height is set extremely low at 85mm, emphasizing aerodynamic efficiency and a low center of gravity. Flared arches and integrated aero vortex generators enhance the visual and functional stance, conveying both technical intent and race readiness.

Powertrain Concept

Race-spec turbocharged inline-4 producing 380hp
Ram-air intakes feeding turbo system
Lightweight exhaust and intake plumbing
Tuned for rapid throttle response and mid-range torque

Engine

At the heart of the Hillclimb Juggernaut sits a race-spec turbocharged inline-four delivering 380 horsepower. Optimized with ram-air intake ducts integrated into the carbon hood and forward-facing heat extractors, the engine breathes efficiently at high altitude and aggressive driving conditions. The setup focuses on immediate throttle response and a strong midrange to handle the rapid elevation changes characteristic of mountain hillclimb events.

Drivetrain

The drivetrain is engineered for maximum traction and agility, paired with an adjustable coilover suspension system set at a race-low 85mm ride height. The widened track and aggressive negative camber angles (-4° front, -5° rear) work in harmony to provide exceptional cornering precision and grip on tight, technical roads. Hydraulic control of the rear wing allows dynamic aerodynamic balance adjustments depending on cornering and straight-line demands.

Fabrication Notes

Carbon fiber panels for hood and rear hatch diffuser
Hydraulic actuation system for rear wing angle adjustment
Custom coilover suspension with adjustable stiffened damping
Precision-machined widebody mounts integrated with chassis
