IMSA has renamed the categories for the new-look Prototype Challenge presented by Mazda championship, which will kick off next year with LMP3 and existing Prototype Lites machinery.

An IMSA spokesperson confirmed to Sportscar365 that the PC1 class will now simply be known as LMP3, with the current L1 class, for the Elan DP02 cars, set to be called MPC, for Mazda Prototype Challenge.

The change puts the championship in line with international standards, as the new top class will be open to all ACO-homologated LMP3 machinery, including the Ligier JS P3, Ave-Riley AR-2 (pictured, above), Ginetta LMP3, ADESS-03 and the new Norma M30.

The 2017 season kicks off at Sebring in March and will feature a pair of 45-minute races in a single-driver format over seven weekends.

    i think its a big mistake for the cars to not have a race at daytona.. its you so called “big event” and you dont have the ladder series for imsa having a race there…. i think they are missing out.

      For what ever reason they never have enough events at Daytona for the 24hr. The last support race I remember on Saturday was HSR Klub sport 911 race and that was over 10 years ago. Plus they don’t start the main race till late in the afternoon so it suck if you camp.

        ferrari challenge races Saturday mornings for at least since the merger but I do agree the imsa ladder should have more of a representation

        CTSC has a race on the Friday of the Daytona 24hr weekend. It’s been a great race, most years.

    Ah I agree but is this rig ready for the high bank speeds? Have they tested there? Maybe that’s their concern. IDK just throwing that theory out there try a more traditional layout first?

      you do realize they/ve raced at le mans and two full seasons of ELMS, daytona really isnt that difficult to set up a car for.

        Is there any data on a high bank? The DPs liked to fly literally when the Conti’s and merger started. That’s my question. I know ELMS, Le Mans isn’t banked 39 degrees. I guess I’m safety guy and conservative I guess when it comes without testing at the actual track that is for high speeds.

          Your comparing a dp that had many years of experience on A highbank that took off. While P2’s which had bever been there with no data never took off…. Plus the P3 is not as powerful nore does it sustain as much downforce, the cars will be fine.

    Conti was the only support race at Daytona last year, too. I suspect the timing of the race has as much to do with not racing at Daytona as anything else. If teams are struggling to get budget or weighing different series, having an extra 6 weeks to find funding is a big deal. There’s also the issue of small northern teams getting cars to Florida in winter. Between those two issues, I can see them deciding to just wait. They only have 7 race weekends anyway, so stretching the season out doesn’t make sense.

    The IMSA Lites series, what will be known as MPC, has never run at Daytona on the Rolex24 weekend.

    Between the WeatherTech series practices and qualifying along with the Continental Tire series practices and qualifying, there ain’t a whole lot of time for anything else except some short vintage sessions.

    That’s my view from the corners.

    • Jack

      Imsa kites never has because they haven’t been under the series that ran Daytona until 2014. Also, there is a surprising amount of downtime at the Rolex weekend from when I was there, I think they could easily fit in another race series.

      • Larry

        October 22, 2016 at 10:05 pm

        I would disagree. Some of that “down time” is so corner workers and others can grab a bite or take a break.

        We have plenty to do without adding more classes.

        The 2014 date does not change what I said in that the IMSA Lites have never run at the Rolex24.

    The Riley is not homologated yet, and will not be ready in time for Daytona. IMSA is ensuring one of their biggest supporters over the last decade will be able to compete. Expect LMP3 as a support race in 2018.

    • Larry

      October 22, 2016 at 10:05 pm

      Probably not.

    I miss the old days where there was a 4 hour historic enduro hhe saturday before the race. That was pre grand-am. It was always a great race too seeing a lot of old gtp cars being driven in anger on the banks again was way cool. 10-12 gtp cars a lot plus a lot of gt cars.

    Chrissy Matthews is prepping the lefturds for the upcoming release of the (forged) long form birth certificate. Up until now, the (forged or not) short form(s) posted online have been THE birth certificate(s) and, if you asked Chrissy or any other lefturd, have been more than enough proof of identity. How odd it would be to a lefturd if suddenly, without reason (as far as they’ve been told) the long form bc is released and made available for the public to see. They need reason so that it’ll all make sense to them. Chrissy is helping feed them that reason.

    Aika radikaalia, että joutuu leikkaamaan kirjastokortin kahtia kuin luottokortin konsanaan. 😀 Voi meitä lukutoukkia. Veikkaan, että esim. tämä keskustelu saattaisi vaikuttaa melkoisen oudolta jonkun ei-kirjahullun mielestä. Jotkut ehkä luulevat, että kirjojen lukeminen on vain lukemista, eikä että siihen liittyy ties millaista päänviirausta ja monenlaisia lieveilmiöitä. 😉
