The 47th running of the Rolex 24 at Daytona is underway, with the event kicking off under sunny and warm conditions in Florida.

From pole position, David Donohue held the lead n the #58 Brumos Riley-Porsche but was soon under pressure from the Penske Riley-Porsche of Timo Bernhard, with the Porsche factory man getting a run on the inside through the turn one oval to dive into the lead at the chicane on the back straight.

Bernhard has now set about pulling out a lead on his rival and leads with ten laps gone from Donohue and Scott Dixon in the #02 Chip Ganassi Racing Lexus.

Max Angelelli, Joao Barbosa and Christophe Bouchut round out the top six after the early stages, with the only DP machine to run into problems thus far being the Victory Junction car of Leo Hindery after he suffered a spin at the chicane. The same car had suffered a practice accident in the hands of Bill Lester.

In the GT class, Sylvain Trembley maintained his lead from the start before slipping back behind the Porsche of Andy Lally. The GT lead however approaching 20 minutes run is held by Dominik Farnbacher, with Lally second and Martin Ragginger third. Trembley however has been forced onto pit-road with the Mazda.
