The Virgin Australia Supercars Championship season-opener will be known as the Superloop Adelaide 500 from 2019.
Superloop is a provider of telecommunications and Internet services in Australia and the Asia Pacific, with 45 staff in Adelaide.
The event ran without a major sponsor in 2018 following an 18-year tenure as the Clipsal 500.
“Over 20 years, the Adelaide 500 has become Australia’s largest domestic ticketed motorsport event, injecting millions of dollars into the state’s economy,” said Minister for Trade, Tourism and Investment, David Ridgway.
“We are delighted to have secured Superloop as the event’s new naming rights sponsor and look forward to a successful partnership that will continue to deliver a world-class race.
“Superloop has a strong local footprint in Adelaide with exciting plans for future expansion.”
Superloop CEO Drew Kelton said the new partnership was the next step in the company’s national expansion.
“We are thrilled to be partnering with the Adelaide 500 as we continue our journey in Australia,” said Kelton.
“Superloop has a solid base in Adelaide and we anticipate the Adelaide workforce will significantly increase as Superloop Home Broadband ramps up. We look forward to sharing our product with fans at the Superloop Adelaide 500.”
The Virgin Australia Supercars Championship will headline the on-track activity, supported by the Dunlop Super2 Series, Porsche Carrera Cup, Touring Car Masters, Aussie Racing Cars, ECB SuperUtes and Audi R8 LMS Cup.
Aussie Racing Cars returns to the support bill with Improved Production and Stadium Super Trucks, recently banned by CAMS, no longer part of the event.
The 2019 Superloop Adelaide 500 will see the debut of the Mustang Supercar, replacing the Falcon for Ford entrants in the Virgin Australia Supercars Championship.
The Superloop Adelaide 500 will take place on 28 February to 3 March 2019.
