Former Champ Car team Pacific Coast Motorsports will join the IndyCar Series from next month's Indianapolis 500 with veteran driver Mario Dominguez.
The team hoped to make the transition from Champ Car to IndyCar for the beginning of the season but the merger came too late for them to change their plans in time.
They ran Dominguez and Alex Figge in the Champ Car finale at Long Beach last weekend and have now confirmed their plans to contest the remainder of the IndyCar season.
Dominguez, who spent seven years in Champ Car and finished third at Long Beach, is looking forward to representing his native Mexico City in the IndyCar Series.
"I'm very excited about this project," said the 32-year-old. "Racing in the Indy 500 is a childhood dream of mine, and it will be a big responsibility to carry the colours of my city and my country in the most important series in North America.
"I'm excited to continue with Pacific Coast. We finished on the podium last weekend and that shows we are competitive and can be champions together."
Pacific Coast Motorsports boss Tyler Tadevic added: "With our recent success at Long Beach, where Mario gave me my first podium as a team owner, we couldn't be more excited and we can't wait to get started.
"This programme is an extension of our belief in the Hispanic market, and of our belief in the Hispanic fans of open-wheel racing and Mario in particular."
