Gallery: 'Roar Before the 24'by Web Editor on 9th January 2017
The annual pre-Daytona test day, the 'Roar before', took place at the International Speedway over the weekend, with the LMP2s leading the way from the new DPis on the timing screens.
Porsche LMP1 racer Neel Jani set the early benchmark, moonlighting with Rebellion Racing alongside Seb Buemi, heading four of the five sessions. But it was resurgent Briton Ben Hanley who set the weekend's fastest lap in DragonSpeed's Oreca. Mazda was the quickest of the new-for-2017 Daytona Protoypes, 0.2s shy of Hanley's weekend best. Just 1.3s covered the entire premier prototype field.
Ryan Briscoe and Tony Kanaan were quickest in GTLM, both in Ford GTs, Porsche's Sven Muller topped GT Daytona, with James French fastest of the five Prototype Challenge cars.
