The Phase I configuration at Apex Motor Club represents Arizona's exclusive private racing facility's original 2.27-mile circuit featuring 12 turns of varying angles across a meticulously designed 40-foot-wide track surface constructed with polymer-modified asphalt matching world-class racing circuits. Located in Maricopa, approximately 30 minutes south of Phoenix, Phase I opened in 2018 as the foundational layout designed by Motorsports Services International, featuring a distinguishable 2,400-foot straightaway and carefully crafted chicanes creating elevation changes and technical sections. The Phase I circuit serves as Apex's primary members-only racing environment, built to professional standards by Sunland Asphalt using advanced paving techniques for superior grip and durability in desert conditions.

What distinguishes Phase I from typical club circuits is the combination of exclusive private ownership with world-class construction quality, creating a facility where affluent motorsport enthusiasts enjoy uncrowded track access without the operational compromises common at multi-use public venues. The 40-foot consistent width throughout the 2.27-mile layout provides multiple racing lines and comfortable overtaking zones, while paved key runoff areas prioritize safety over the grass-and-gravel consequences defining older facilities. Arizona's high desert climate at Maricopa creates extreme temperature variations with summer afternoon track temperatures routinely exceeding 65C, demanding careful tire management and vehicle cooling strategies, while winter mornings can see near-freezing starts before afternoon warming. The membership-based model ensures track time availability without public track day congestion.
