Gonzalez was part of the Anglo-Russian squad throughout 2013 and drove in free practice at the Hungarian and Italian Grands Prix.
The Venezuelan also has extensive experience in GP2, albeit without a great deal of success. Gonzalez scored 10 points over three seasons in the series between 2010 and 2012.
His test with Coyne suggests he could be in line for the team's second seat, which has typically been filled by a well-funded driver. This year Colombian Carlos Huertas took up the reins and scored a shock win at Houston.
“[The test] was a great experience, and I am very grateful for this new opportunity to return to the track," Gonzalez is quoted as saying by NBC Sports.
"I was worried because I had no time to handle such a large and fast car, in a category that is one of the most important worldwide. I was surprised by the speed, it’s totally different from Formula 1 and World Endurance prototypes.”
