A handful of prototype and GT cars hit the Florida track to prepare for their respective seasons.
Teams from several series of endurance racing have converged at Sebring International Raceway this week for private testing.
Audi and Porsche have crossed the pond to test their new LM P1 machines that will compete head to head in the FIA World Endurance Championship this season. The two teams have set up in opposite locations at the circuit, with the Audi R18 e-tron quattro based at the infield paddock and the Porsche 919 Hybrid working out of the normal paddock. It is believed this is the first time the two cars have run on the same track at the same time, giving the chance for them to directly compare themselves to each other, albeit with unofficial times.
In the GT class, Porsche and BMW are both present. The Stuttgart marque is pulling double duty with the aforementioned 919 Hybrid and the 911 RSR GTLM both on track. Two factory BMW Z4 GT3 cars destined for the 24 Hours of the Nürburgring this summer are also on hand, with works driver Dirk Müller leading the test.
