title：Rhys Millen’s 2013 Pikes Peak Genesis Coupe: Key Design Modifications
content: Rhys Millen’s 2013 Pikes Peak Genesis Coupe: Balancing Identity & Speed
Imagine standing at the base of Pikes Peak, watching a race car that looks familiar yet utterly fierce. That’s Rhys Millen’s 2013 Genesis Coupe—built to defend his 2012 Pikes Peak record. The video dives into how he blended the production car’s iconic design with race-ready upgrades. After analyzing this footage, I believe the balance between identity and performance is what makes this build stand out.
Design Philosophy: Retaining Production Roots While Racing
Millen’s team didn’t start from scratch. They wanted the unlimited racer to feel like a Genesis Coupe first. To do this, they took a production model and created a mold splash of its A, B, and C pillar lines. This kept the car’s structural identity intact.
Two key production features were non-negotiable: the rear quarter window’s saddle dip into the fender and the hexagonal grille flanked by distinctive headlights. These elements ensure anyone can spot the Genesis Coupe DNA, even in its race-tuned form. The team enhanced the saddle feature by enlarging the rear fenders to fit larger tires—practical and true to the original design.
Technical Modifications for Peak Performance
Every tweak served a racing purpose. The final car sits 10 inches lower than the production model. This reduces frontal area and drag, helping Millen reach a target top speed of 145 mph. Lower height also improves airflow to the rear wings, boosting downforce in tight corners—critical for Pikes Peak’s winding roads.
Large air scoops on the sides feed air to the engine oil cooler and turbo intercooler. These aren’t just aesthetic; they keep the engine running at optimal temperatures during the grueling climb. Each modification is a blend of form and function, showing Millen’s expertise in race car engineering.
What’s Next? Teasing Pre-Race Testing
The video teases that the next episode will cover pre-race testing. This is where the design choices will be put to the test. Will the lower height improve speed without sacrificing stability? Can the air scoops handle the mountain’s changing temperatures? These are questions racing enthusiasts will be watching closely.
Not mentioned in the video, but worth noting: hill climb races demand a unique balance of power and aerodynamics. Millen’s focus on retaining production design while optimizing for performance could set a precedent for future race builds that honor their street car roots.

If you’re a race car design fan or looking to modify your own vehicle, here are actionable steps inspired by Millen’s build:
- Preserve iconic features: Identify 1-2 key design elements of your base car to keep—this maintains identity.
- Prioritize height reduction: Lowering your car (within safety limits) cuts drag and improves downforce.
- Add functional aerodynamics: Use air scoops or wings that serve a purpose, not just look good.
- Test modifications: Always validate changes in real-world conditions (like Millen’s pre-race testing).
For further learning, I recommend the book Hill Climb Racing: Engineering and Strategy—it breaks down how aerodynamics and design impact mountain race performance.

Rhys Millen’s 2013 Genesis Coupe is a masterclass in balancing production identity with race-ready performance. Every design choice—from the retained hexagonal grille to the 10-inch lower height—serves a clear purpose.
