Series: NASCAR O’Reilly Auto Parts Series (Race 22 of 33)
Venue: Indianapolis Motor Speedway (IMS) — Speedway, Indiana
Race Distance: 100 laps, 250 miles (402.336 km)
Course Type: Permanent racing facility, 2.5‑mile oval
Venue & Track Description — Indianapolis Motor Speedway
IMS is the most iconic racing venue in the world:
Location: 4790 West 16th Street, Speedway, Indiana — six miles west of downtown Indianapolis
Opened: 1909 — the original “speedway”
Capacity: ~235,000 permanent seats; up to ~400,000 with infield seating (largest sports venue globally)
Track Type: Nearly rectangular 2.5‑mile oval
Turns: Four 0.25‑mile flat corners
Long Straights: Two 0.625‑mile straightaways
Short Chutes: Two 0.125‑mile straights between Turns 1–2 and 3–4
Backstretch: The long straight between Turns 2 and 3 — critical for drafting and momentum runs
Track Character:
Very flat by NASCAR standards
Precision‑based driving
Aerodynamic balance and long‑run stability matter more than raw aggression
IMS is famous for exposing weaknesses in car setup, tire management, and driver discipline. It is not forgiving — indecision or overdriving corners often leads to lost momentum for an entire lap.
