The Americas Rallycross Championship, also known as ARX Rallycross, was an American rallycross series organized by IMG Motorsport. Formed in 2018, it was a feeder series to the FIA World Rallycross Championship. After two seasons, ARX shut down in late 2019.
In March 2018, IMG founded the Americas Rallycross Championship as a competitor to the GRC Rallycross until the latter folded due to financial issues.[1] Former GRC teams like Andretti Autosport and Subaru Rally Team USA moved to ARX.[2]
ARX's inaugural race was held in May at Silverstone Circuit as a support to the World RX of Great Britain; Tanner Foust won the event.[3] The first American round took place in July at Circuit of the Americas, won by Scott Speed.[4] Speed ended the 2018 season as the champion, his fourth consecutive title in a rallycross series.[5] The series also hosted the ARX2 class, a second-tier league with spec Ford Fiestas.[6] In 2019, ARX conducted a six-race schedule with rounds on new rallycross courses at Mid-Ohio Sports Car Course and World Wide Technology Raceway at Gateway. Foust went on to win the championship. Only seven teams competed in the 2019 season.[7]
On November 15, 2019, IMG announced the series would fold after just two seasons following a failed search for commercial partners.
