2010 RMR PM580 Pikes Peak

In the world of racing, Unlimited, means “Anything Goes.” Unlike other forms of motorsport (NASCAR, Indy Car, F1, etc.) the Pikes Peak International Hill Climb Unlimited Class gives teams the freedom to create any kind of race car they want to conquer the mountain without restrictions on tires, weight and horsepower. Teams can make their cars as light as possible, with an unlimited amount of horsepower and with whatever braking, drivetrain or suspension package they desire.

With this in mind, Rhys Millen Racing is fabricating a modern Le Mans style car with a target weight of 1,850 pounds powered by a 4.1-liter Hyundai Lambda turbocharged V6 engine. The team feels to have a competitive power-to-weight ratio, the car will need to produce 675 horsepower. Current engine testing shows the engine is capable of producing 750 horsepower, which is more than needed to tackle the mountain.
The car will feature a carbon fiber aerodynamic body with an active rear wing. The wing will create less drag in the straight-aways and more stability in cornering and braking. Active wings are outlawed in other forms of racing.

“We are building a car for today’s road,” said Millen “The car will have a sleek aerodynamic body, the grip of Toyo Proxy tires and the power and durability of a Hyundai engine. This is the package I need to break the record.”

The RMR Hyundai Genesis PM580 will use an active center differential. This differential will allow a 10 to 100 percent torque split to the front wheels. This is important because the course changes from asphalt to dirt multiple times and allows the Genesis PM580 to have more than one set up on the 12.42-mile course. The car will be ideal on the mixed surface at Pikes Peak. The Genesis PM580 address a fundamental reason on perhaps why the 10-minute record has not fallen. Most race cars do not work well on both dirt and asphalt.
