Prior to this weekend’s GT Open-sanctioned Winter Series event at Paul Ricard, AF Corse was testing at Vallelunga with its Ferrari 458 GTE cars that will compete in the FIA World Endurance Championship. (En Français)

At least two drivers were evaluated in the test, including GP2 standouts James Calado and Sam Bird. Belgian driver Jerome D’ Ambrosio had tested with the team earlier in the year, with all three understood to be in contention for the fourth and final full-season seat in the team’s two-car GTE-Pro program.

Calado finished third in GP2 last year with ART Grand Prix, while Bird, who made his sports car debut in January’s Rolex 24 at Daytona in a PC car, finished runner-up in the open-wheel series in 2013.

Team owner Amato Ferrari told Endurance-Info on Thursday that the final decision on the driver pairings for the Nos. 51 and 71 Ferraris have not yet been made. At present, only Gianmaria Bruni (No. 51) and Davide Rigon (No. 71) are confirmed, with Toni Vilander’s placement to-be-determined.

The team had to fill two positions for 2014, following Giancarlo Fisichella’s move to the TUDOR United SportsCar Championship with Risi Competizione and Kamui Kobayashi retuning to Formula One.
