Southwestern International Raceway™ (SWIR) is a 110-acre venue located at the Pima County Fairgrounds, 10 miles from downtown Tucson, Arizona. The track features a dedicated quarter-mile Drag Strip and first opened in August 1997. Over the last 16 years, SWIR has hosted such premier events as the International Hot Rod Association’s Nitro Jam and Thunder Jam, Pro Nitro Warm-Up, Super Chevy Show, Pacific Street Car Association (PSCA), Import Face-Off, and Tucson Dragway Reunion. With one of the largest shut-down areas in the country at almost three-quarters of a mile, SIR has run some of the fastest race cars in the world. Driving schools, professional testing sessions, private rentals, and corporate team-building events are also held at SWIR year-round. IRG Sports + Entertainment™ (IRG) acquired the facility from former owner operators Jon Bradford and Tom Koenan in August 2013. IRG also owns and operates Palm Beach International Raceway™, Memphis International Raceway™ and the International Hot Rod Association™.
