Rubens Barrichello will make his Daytona 24 Hours debut in a Porsche GT car, shared with former IndyCar team-mate Tony Kanaan.
The two Brazilians are joining Dener Motorsport for this weekend’s pre-race test.
Barrichello recently announced that he would leave the IndyCar Series after a single season to switch to Brazil’s Stock Car V8 championship.
He had previously been team-mates with close friend Kanaan at KV Racing Technology.
The pair will share Dener’s Porsche GT3 with Stock Car V8 frontrunners Ricardo Mauricio and Flavio Figueiredo.
