Road America
Road America dice ser “la pista de carreras más rápida del mundo” con un impresionante promedio de velocidad de 95 MPH, y no hay muchas otras pistas capaces de objetar eso. Fue pavimentada en abril de 1955 en 640 acres (260 ha) de colinas en la morrena Kettle, en Elkhart Lake, a 60 millas al norte de Milwaukee. Clif Tufte, un ingeniero de autopistas, concibió la idea de construir una pista de carreras después que las autoridades Elkhart Lake prohibieran las carreras callejeras a principios de los 50. La pista de 4.0 cuatro millas con 14 curvas que él diseñó y construyó forma parte de muchas series de deportes a motor de alto perfil tales como la WeatherTech SportsCar Championship, IndyCar, NASCAR Cup, NASCAR Xfinity, MotoAmerica, la American Le Mans y muchas otras. La audiencia combinada de estos eventos es de más de 800,000 espectadores cada año.
El clima continental húmedo de Wisconsin significa que hay veranos suaves con muchas lluvias e inviernos fríos y nevados con temperaturas bajo los 30° Farenheit. Sin embargo, los deportes a motor nunca se detienen en Road America, con más de 400 eventos al año tales como la famosa Winter Autocross Series, que se realiza sin importar las duras condiciones climáticas existentes. El trazado la pista es óptimo para altas velocidades, con segmentos rectos largos y con curvas prolongadas que brindan cambios de elevación espectaculares como el que se encuentra llegando a la línea final, que luce como una pared vertical desde el asiento del conductor.
Road America's Current configuration preserves the 6.472-kilometer 'National Park of Speed' layout that has defined Wisconsin road racing since 1955, featuring 14 turns across 259-hectare facility near Elkhart Lake where recent repaving modernized surface characteristics while maintaining the circuit's fundamentally unchanged geometry that makes it North America's premier natural-terrain road course. This FIA Grade Two circuit combines long straights rewarding top speed with technical sections demanding precision through corners following natural landscape contours rather than bulldozed flat design, creating the balanced character that attracts IndyCar Series, IMSA SportsCar Championship, MotoAmerica Superbike Championship, and numerous club racing organizations year-round. The Current designation distinguishes this modern-surface variant from historical configurations, though Road America's layout remains remarkably consistent with founder Clif Tufte's 1955 original vision where minimal geometry changes across seven decades demonstrate timeless circuit design.
The Current configuration's character derives from preserved classic layout combined with contemporary surface quality. Recent repaving created the 'National Park of Speed' descriptor celebrating smooth asphalt and modern grip levels, but the 14-turn geometry maintains traditional challenges: Turn 5's off-camber Carousel demands precise line selection, the Kink's high-speed compression tests courage at 240+ kph, Turn 12's hairpin requires patience before Canada Corner's final complex. The 6.47-kilometer distance creates lap times around 2:00-2:10 for professional prototypes and open-wheel cars, making it one of North America's longest permanent road courses where mistakes in any of 14 corners cost significant recovery time. Wisconsin's continental climate creates dramatic seasonal variation—summer events see track temperatures approaching 40°C while spring and fall races operate in cool conditions, with afternoon thunderstorms common during racing season. Road America's 640-hectare facility preserves vast run-off areas and spectator viewing opportunities across natural amphitheater terrain. The Current configuration particularly showcases how classic 1950s circuit design remains relevant in modern motorsport, where recent surface improvements enhance rather than compromise the fundamental layout that established Road America's reputation as North America's most complete natural-terrain road racing challenge.
