Bruno Junqueira and Luis Diaz will compete at the inaugural FIA WEC Six Hours of Mexico in September with Roberto Gonzalez and Greaves Motorsport.
As previously revealed by Sportscar365, the 2015 European Le Mans Series LMP2 championship-winning team will field a Gibson 015S at the Mexican round of the FIA World Endurance Championship with an all-Latin American trio of drivers, in promotion of the event.
Gonzalez confirmed the lineup via Twitter on Sunday.
Roberto Gonzalez is the older brother of Ricardo, who serves as promoter for the event but also races full-time in WEC with RGR Sport. Both Gonzalez brothers are Silver-rated by the FIA.
The former Champ Car driver previously raced for Greaves at the 2012 Six Hours of Sao Paolo (pictured above), subbing for Ricardo. He also has previous Prototype Challenge experience with RSR Racing, the team which Junquiera was long associated with.
Diaz is no stranger to prototype racing either, with the Mexican driver a former American Le Mans Series P2 champion with Fernandez Racing and more recently having driven for Level 5 Motorsports and 8Star Motorsports in both P2 and PC, respectively.
Junqueira and Diaz, meanwhile, are set for their WEC debuts and are expected to get their first laps in the open-top prototype in a test at Monza prior to the round at the Autodromo Hermanos Rodriguez.
The Greaves car is expected to be a one-off entry for the Mexico City event only.
