INDYCAR has released the second half of its 2027 NTT INDYCAR SERIES schedule, rounding out a mix of fan-friendly and dynamic race weekends leading up to the climactic moment at WeatherTech Raceway Laguna Seca when the 2027 INDYCAR SERIES champion hoists the Astor Challenge Cup.

The announcement also included the introduction of the inaugural INDYCAR Grand Prix of Barcelona at  Circuit de Barcelona-Catalunya, the series' first international event outside North America since 2013. (Read more below).

"The 2027 season will build off a record-shattering and landmark year for the NTT INDYCAR SERIES," Penske Entertainment Corp. President and CEO Mark Miles said. "The sport's growth has been immense, driving incredible viewership gains, reaching new fans in younger demos and attracting increased commercial interest from emerging and long-term partners. Our relationship with FOX Sports continues to set an industry standard, and this schedule will help us build on all of these gains and take things to the next level."

For the third consecutive season, all races will be broadcast on FOX in the United States, with three additional telecasts scheduled during the two days of qualifying for the Indianapolis 500 presented by Gainbridge and coverage of Miller Lite Carb Day at Indianapolis Motor Speedway. The NTT INDYCAR SERIES is once again the only premier motorsports series in North America with all races broadcast on network television.

"One of the things that makes INDYCAR so special is that winning a championship requires drivers and teams to be competitive on every type of racetrack," INDYCAR President J. Douglas Boles said. "From high-speed ovals to tight street circuits and challenging road courses, they face a different test almost every weekend. The 2027 schedule continues that tradition, featuring the 111th Running of the Indianapolis 500, alongside some of the most iconic racetracks in North America, and the historic addition of Circuit de Barcelona-Catalunya. With 25 full-time entries battling for a championship and every race broadcast on FOX, our fans have an incredible season of racing to look forward to."

INDYCAR Adds International Event at Circuit de Barcelona-Catalunya in 2027

INDYCAR is expanding its global footprint with a new international event at Circuit de Barcelona-Catalunya in Spain as part of the 2027 NTT INDYCAR SERIES schedule.

The inaugural INDYCAR Grand Prix of Barcelona is scheduled for Sunday, July 18, and will bring North America's premier open-wheel racing series to Spain for the first time, setting the stage for a spectacular homecoming for Barcelona native and five-time NTT INDYCAR SERIES champion Alex Palou of Chip Ganassi Racing, series officials said.

The multiyear agreement with Circuit de Barcelona-Catalunya marks the NTT INDYCAR SERIES' first race outside North America since 2013, when James Hinchcliffe won on the streets of São Paulo, Brazil. The event also signals a European return for the INDYCAR SERIES, which last competed on the continent in 2007 at the TT Circuit Assen in the Netherlands.

"This is a monumental day for our sport," Miles said. "We are pleased to be able to take our ultra-competitive brand of wheel-to-wheel racing to Europe and thrilled that we can showcase INDYCAR in Alex Palou's hometown. We have seen Alex's remarkable skill and talent for several years and know his fans in Spain have been clamoring to watch him race in person.

"We cannot wait to see the NTT INDYCAR SERIES compete at one of the world's most recognizable motorsports venues set against the backdrop of a very historic and breathtaking international destination like Barcelona."

Palou, a 29-year-old Spaniard, captured his fifth NTT INDYCAR SERIES championship in 2026, becoming just the second driver in series history to win four consecutive titles, joining Sebastien Bourdais (2004-07). With five championships in six years and 25 career victories, Palou is tied for 17th on the series' all-time wins list. Only A.J. Foyt (seven) and Scott Dixon (six) have won more INDYCAR SERIES championships.

"I'm so excited to be part of INDYCAR's first race in Barcelona," Palou said. "It is an amazing opportunity, and it means so much to me to have a race at home in Barcelona, it's hard to put into words. I know the fans are going to love it, and I think we are going to put on a great show. We're going to try hard with the team at Chip Ganassi Racing to bring home the trophy in July."

Located in Montmeló, just outside Barcelona, Circuit de Barcelona-Catalunya has been a fixture on the international motorsports stage since opening in 1991. The renowned road course has hosted some of the world's most prestigious racing championships, including FIA Formula One and MotoGP, and is recognized for its combination of high-speed corners, technical sections and demanding layout.

The addition of Barcelona marks another significant milestone for INDYCAR as the series continues to introduce its high-speed, ultra-competitive brand of racing to new audiences and build upon its growing momentum.

"The arrival of INDYCAR is a major milestone and an exciting challenge for the Circuit de Barcelona-Catalunya," Chairman of the Board of Fira de Barcelona and Fira Circuit Pau Relat said. "Bringing one of the most prestigious and spectacular championships in global motorsport to our venue strengthens our international positioning, connects us with new audiences and markets, and reinforces our strategy of diversifying the circuit's activity through world-class events. We are working with a long-term vision to make INDYCAR Grand Prix of Barcelona a benchmark event on the international racing calendar for years to come."

Phase Two of the 2027 NTT INDYCAR SERIES schedule, which will include a listing of all races in next year's championship, will be announced shortly. Tune-in times for next season's events will be announced at a later date.
