Five-time American Le Mans Series champion Olivier Beretta will return to the series with the Risi Competizione Ferrari team in 2013.
The Ferrari factory driver, who scored his sequence of GTS/GT1 titles with the ORECA Chrysler and Corvette Racing teams, will race Risi's solo GTE class 458 Italia. The 43-year-old will be joined in the car by Matteo Malucelli, who is returning to the marque with which he won the GT2 class at the 2008 Spa 24 Hours.
Team boss Giuseppe Risi said: "In Olivier and Matteo we have an excellent combination of speed, youth and experience with which to launch our assault on the championship, and I have high hopes for this partnership."
A third driver for the Sebring 12 Hours has yet to be announced.
Beretta joined Ferrari ahead of last season, following his departure from Corvette Racing, and contested the World Endurance Championship with the AF Corse team.
