Mowlem repeated his pole-grabbing performance at Daytona when he captured the Prototype Challenge class pole position in advance of the 2016 Rolex 24 at Daytona. During a driving rain storm, Mowlem posted the quickest qualifying time overall but race administrators elected to start the field according to category, which put the more powerful Daytona Prototype cars at the front of the field. Mowlem finished third in class in the race. Will also compete in a Ferrari 458 GT3 for the factory-supported FF Corse in the European Le Mans GT3 Cup Championship.
