The two Porsche 963 fielded by the Porsche Penske Motorsport factory team are holding their ground among the frontrunners in the early stages of the 24 Hours of Daytona. In the first four hours of the endurance classic in Florida, Brazilian Felipe Nasr advanced to second place at the start in the #7 car and defended his position over many laps. In the first hours, his British brand colleague Nick Tandy worked his way up the order to fourth place in the #6 sister car. The Porsche 963 customer teams were also looking strong as the sun set. The partner teams in the two GT classes brought their Porsche 911 GT3 Rs through the first four hours of the race unscathed.
