Action Express Racing led the way in the opening day of testing at Daytona International Speedway, in preparation for next month’s Rolex 24 at Daytona.

The No. 31 Cadillac DPi-V.R of Dane Cameron, Eric Curran, Mike Conway and Seb Morris unofficially laid down a best lap of 1:38.766 late in the day to go quickest of the five Prototypes in action.

It came after a troubled day for all three Cadillacs, which battled electrical issues tied to an overnight software update from Cosworth.

Both the No. 31 entry and the No. 10 Wayne Taylor Racing Cadillac didn’t make the three-hour morning session, and turned only a total of 19 and 20 laps, respectively, on Tuesday.

The No. 10 car ran without telemetry and completed short stints in the afternoon. Adding to the issues, the No. 5 Action Express car was seen getting a push start from pit lane.

Action Express, however, managed to get its No. 5 Cadillac running from the late morning through the rest of the day, completing 56 laps with Joao Barbosa, Christian Fittipaldi and Filipe Albuquerque at the wheel.

The pair of Riley-based prototypes from Mazda and VisitFlorida Racing, meanwhile, also battled unrelated teething issues, and were unofficially some two seconds slower than the Cadillacs.

The No. 90 VisitFlorida Racing Riley Mk. 30 Gibson laid down a best lap of 1:40.714, while the No. 55 Mazda RT24-P recorded a 1:41.117 from the morning.

None of the times from the new DPi/LMP2 cars were representative of their true potential, with all teams still at the early phase of development.

Corvette Racing was quickest in GT Le Mans, with a 1:45.442 lap set by the No. 3 Corvette C7.R, while the No. 27 Dream Racing Lamborghini Huracan GT3 led the way in GT Daytona, thanks to a 1:45.957, also set in the morning.

No major incidents were reported, with teams back on track tomorrow for the second and final day of testing.

RESULTS: Daytona December Test Day 1

    New cars,teething issues-It wouldn’t be surprising if a GTLM car won the Rolex 24 this year.Hope they can all run strong and long!

      That is asking alot…like a 15+ prototype field to all bite it. Doubtful.

        GTLM winners have finished 7th, 4th, and 6th overall last 3 years so not completely out of the question.

          Firstly, never closer than 14 laps down. As I said. Doubtful.

          Secondly, doubtful does not mean completely out of the question, so I really don’t know what point you are trying to make, since no one has yet said it was completely out of the question.

    So I take it the Mazdas are not using the Cosworth?

    • John Dagys

      Correct. They are using Life Racing Systems, afaik

      • Prashant

        That would be correct. AER and Life Racing are sister companies, so the use of the AER engine essentially mandates the use of Life electronics.

    I suppose the DPIs or better yet, just the Cadillac DPis will smoke the LMP2s. Nothing new here, same bs different year.

        The Visit Florida Riley is the P2…and P2 is not spec, only the engine in ELMS and WEC. there are 4 different manufacturers for the category.

          p2 is spec and has been spec for years now,there is 4 different manufacturers but they all must use the same spec engine now and all 4 chassis must fit within the same spec guidelines with a little freedom in design,but still spec.

    going to be interesting to try and pick out the various DPis at night – the Caddie has a heck of a LED array of marker and headlights…

    GT3 cars clearly are going to be quicker this year. GTLM I think will be just fine in terms of speed I think. There is a lot left in them. There is no class where teams sandbag more than them.

    I would have to say that I think Rebellion Racing has the best shot at this. Only moving down from lmp1 to lmp2 cars. Sure they’re not testing at Daytona but string lineup and the least amount of teething issues I think they’re the best to take it.

    In 2001,Corvette Racing won over a field of 15 prototypes that fell by the wayside.Also the year before,the Oreca Viper pulled off a win,so it’s not out of the question.Daytona is always long and brutal…

      Apples and oranges. In 2001, for example, half the P field was outpaced by GT cars. There were only the top 4-5 P cars back then that were setting a pace gap more or less equivalent to what the P-GT gap is today.

      I don’t imagine even the slowest P car getting outpaced by a GT this year. Already the Ps are hitting times that would set them 6 seconds adrift from the fastest GTs last year, and it will no doubt drop another 1-3 seconds by race day.
