This move positioned him against top American and international drivers on diverse terrains, including forests and mountains, where his precise driving and vehicle preparation skills began to shine.[1] Millen's breakthrough in the SCCA PRO Rally came swiftly, as he secured the overall drivers' championship in 1981 with eight victories across the season, driving a rear-wheel-drive Mazda RX-7 alongside co-driver Bob Kraushaar.[24] His success continued in 1985, when he clinched another national title, winning key events like the Olympus Rally in a four-wheel-drive RX-7 evolution, contributing to Mazda's manufacturer championship that year. These triumphs established Millen as a leading figure in American rallying, with his innovative use of rotary engines and suspension tuning providing a competitive edge in high-speed gravel stages.[25] From 1987 to 1989, Millen achieved consecutive SCCA National Rally Championships, solidifying his reputation as one of the decade's most consistent performers. In 1987, he won five rallies in a Mazda 323 GTX, securing both drivers' and manufacturers' titles with co-driver Harry Ward. The following year, despite a condensed schedule, he captured three victories to defend his crown, and in 1989, partnering with Tony Sircombe, he dominated with six wins en route to his fifth SCCA title of the era. These back-to-back successes highlighted his adaptability to evolving regulations, including the rise of turbocharged four-wheel-drive cars.[1][24] Millen's transition extended to the global stage in 1989, when he made his prominent World Rally Championship (WRC) debut with Mazda's official team, competing in the Rally of New Zealand—a home event that drew on his early roots. Driving the Mazda 323 4WD, he finished second overall, just behind Ingvar Carlsson in another Mazda 323 4WD, earning his first WRC podium and demonstrating his prowess on the demanding gravel roads of his native country. This result, achieved with Sircombe, underscored Millen's readiness for elite international rallying and boosted Mazda's presence in the series.[26]1990s: Pikes Peak Ascendancy
In the early 1990s, Rod Millen shifted his focus toward hill climb racing, particularly the demanding Pikes Peak International Hill Climb, where he began establishing himself as a dominant force in specialized classes. His entry into the event's Open Class in 1991 marked a significant milestone, as he secured his first victory there driving a Mazda RX-7, surpassing the previous class record by over a minute with a time that highlighted his adaptation to the mountain's treacherous 12.42-mile course. This win demonstrated Millen's growing expertise in high-altitude, gravel-surface challenges, building on his rally background to navigate the 156 turns and elevation changes effectively.[27][28] Millen's success continued in 1992 when he claimed victory in the Showroom Stock division, piloting a Hyundai Scoupe to a class-winning time of 13:21.17, marking his first overall Pikes Peak triumph in a production-based vehicle category. This achievement underscored his versatility across vehicle types, from modified prototypes to near-stock models, and solidified his reputation in U.S. hill climb circuits. Concurrently, Millen excelled in the Mickey Thompson Entertainment Group (MTEG) Stadium Series, capturing the Grand National Sport Truck championship that year in a Toyota truck, initiating a streak of dominance in short-course off-road stadium events.[29][30][2] By 1993 and 1994, Millen's prowess in the MTEG series reached its peak, as he defended his title consecutively, becoming the only driver to win three straight championships in the 12-year history of the series, again driving Toyota entries that showcased his off-road handling skills in compact stadium venues. His Pikes Peak campaign culminated in 1994 with an overall victory and course record in a custom Toyota Celica Turbo 4WD, developed through his MillenWorks outfit, achieving a blistering time of 10:04.06—shattering the prior mark by nearly 40 seconds on the all-dirt layout. This record-setting run, powered by an 850-horsepower turbocharged engine, exemplified Millen's integration of advanced engineering with precise driving to conquer the mountain's extremes.[31][2][32]2000s–Present: Off-Road and Legacy Events
In the early 2000s, Millen transitioned to short-course off-road racing, achieving notable success in the Pro-4 class of the Championship Off-Road Racing (CORR) series during the 2000 season. Driving a Toyota Tundra prepared by his team, he secured victories at key events, including the season-opening round at Bark River International Raceway in August, Round 5 at Luxemburg Speedway in Wisconsin, and the October finale at Heartland Park Topeka. These results contributed to a runner-up finish in the overall Pro-4 points standings, demonstrating his adaptability to the demanding stadium-style racing format.[33][34][35][25] Millen continued his off-road pursuits with family involvement in the 2006 Tecate SCORE Baja 1000, partnering with his son Ryan Millen in a Toyota FJ Cruiser to claim second place in Class 5 for production vehicles. The pair completed the grueling 1,050.83-mile loop course from Ensenada in 34 hours, 37 minutes, and 18 seconds, finishing just behind the class winner. This effort underscored the collaborative spirit within the Millen family racing team.[36] The 2007 Transsyberia Rally marked a high point in Millen's later competitive career, as he and co-driver Richard Kelsey piloted a Porsche Cayenne S to overall victory. Covering 7,100 kilometers across rugged terrain from Moscow, Russia, to Ulaanbaatar, Mongolia, over 14 stages in two weeks, the American duo edged out the competition by a narrow margin in what was hailed as one of motorsport's toughest endurance challenges.[37] Around 2010, Millen stepped back from full-time competitive driving, redirecting his expertise toward mentoring emerging racers, including his sons Rhys and Ryan, while occasionally appearing in non-competitive capacities. This shift allowed him to preserve his legacy through advisory roles and special appearances.
