Testing is underway at Sebring today in preparation for the opening round of the 2013 American Le Mans Series – the historic final time time for the P1 machines will do battle in central Florida.

With Audi back at the historic airfield circuit for one final assault, the competition for overall honors is expected to be fierce with ALMS regulars Muscle Milk HPD, Dyson Racing Mazda and series newcomers Rebellion looking to prevail over the 10-time Sebring winning German manufacturer.
