Join us on Sunday, August 2, 2026 from 10:00am – 2:00pm for a FREE, family-friendly day of food, fun, and an incredible selection of vehicles as we celebrate the 30th Anniversary of the historic Tustin Thunder Road Races and more than 30 years of giving through the Marconi Foundation for Kids.

This year’s Open House will pay tribute to one of Orange County’s most memorable motorsports events, the Tustin Thunder Road Races. Originally held at the former Marine Corps Air Station Tustin beneath the iconic Tustin Blimp Hangars, Tustin Thunder brought together racers, collectors, and enthusiasts from across the country for a weekend unlike any other. Spearheaded by John Marconi and the Marconi Foundation for Kids, the event featured vintage road racing on a temporary course built from the military base’s taxiways and helicopter pads, along with a massive car and motorcycle show, karting, drag racing exhibitions, family entertainment, and more. Drawing tens of thousands of spectators, Tustin Thunder became one of Orange County’s most memorable automotive events while supporting the Marconi Foundation for Kids and its charitable mission of helping kids.

Last Year, we had the privilege of once again hosting our annual Marconi Open House event, and what an incredible day it was! From the moment the doors opened, the event was filled with energy, excitement, and a community of people who share a passion for cars and a commitment to giving back! Thank you to everyone who made this event possible. To our amazing volunteers and staff, your hard work, hospitality, and dedication behind the scenes.

Thank you for your continued support and for joining us in building a brighter future for the children who need it most. A portion of the net proceeds from everything we do at The Marconi Automotive Museum & Foundation for Kids directly supports our mission of helping kids in need, and through your support and participation, we’re able to make a meaningful impact!
