Mazda has unveiled its DPi challenger, the RT24-P, which will make its debut in January’s IMSA WeatherTech SportsCar Championship season-opening Rolex 24 at Daytona, with a two-car factory Prototype class effort.

The Japanese manufacturer took the wraps off its highly anticipated program Wednesday at the LA Auto Show.

The RT24-P, which signifies “Mazda’s Road to 24” program, as well as its two-liter, four-cylinder Mazda MZ-2.0T engine, will be based on the Riley Mk. 30 LMP2 chassis, designed and built by Multimatic-Riley.

It features custom bodywork, manufactured by Multimatic and utilizing Mazda’s KODO-Soul of Motion design philosophy, including sleek body contours and the five-point Mazda grille.

“This is a huge moment for Mazda Motorsports and the entire Mazda family,” said Mazda Motorsports North America director John Doonan.

“To have a car which features Mazda design language at the top level of our motorsports program is meaningful for us as a brand. We believe we have the right team, the right drivers and the right chassis to win races and championships.”

SpeedSource will again operate the factory Prototype program for the third consecutive season, with all four of its full-season drivers: Jonathan Bomarito, Tristan Nunez, Joel Miller and Tom Long expected to be back as well.

Its relationship with AER will also continue, with the same MZ-2.0T engine that was utilized in its Lola-based prototypes this year.

Additionally, Mazda will become the first team to test the Riley Mk. 30 LMP2 chassis later this month.

“Mazda has good, long-standing relationships with Riley and Multimatic, and is happy to be the first to test their new chassis,” Doonan said.

“We look forward to seeing it make its racing debut at Daytona with Mazda bodywork and the Mazda MZ-2.0T engine.

“The strategic vision of IMSA to give auto manufacturers this opportunity to integrate our branding, to better engage our passionate fans, is unique and we’re proud to be the first to unveil what is possible.”

The car is expected to make its public test debut in next month’s IMSA-sanctioned test at Daytona on Dec. 13-14, which is mandatory for all DPi manufacturers and LMP2 constructors.

Mazda is one of three expected DPi manufacturers to be on the grid at Daytona, joining the previously confirmed Nissan customer program with Tequila Patron ESM, and the yet-to-be-announced Cadillac DPi effort with Action Express Racing and Wayne Taylor Racing.

    Will be interesting to see how it stacks up against the traditional lmp2’s

      That’s the thing about racing in IMSA, the series will equalize the cars to such a degree that we’ll never really know who has engineered the best Race car in P2.

        Mazda has a new generation rotary engine that if combined with an electric hybrid ,minus the traditional trans ,but with an electronic variable drive ,and fueled by LPG !COMPACT,Green,and doeable.

      Considering that the DPi’s are on a base LMP2 chassis and the engines are gonna be pretty close to the Gibson engine.

      It should be alot easier to BoP than the previous screw-job from the DP/LMP2 debacle.

    Any word as to when Cadillac is unveiling theirs? I would have assumed it would have been in LA since it wasn’t Pebble Beach, but we’re running out of days in the week….

      No official time that I’ve heard but I think the LA Show was what the expectation was

    • Larry

      November 19, 2016 at 3:27 pm

      Last I heard, they are having some sort of contract issues.

      I wonder what’s gonna happen if they don’t have their bodywork by the mandatory test days next month.

      Cadillac must be playing musical chairs concerning what powerplant to use.THE 3.6TTV6 WAS DEVELOPED FOR sprint racing,the 4 camm 4.2v8 is not ready for enduro racing, so that leaves a 6.2 LS3, TO HAUL THE MAIL !

    That DPi idea was genius! I was skeptical at first, the FIA/ACO better hope onboard if they want lmp1 to survive

      Not sure how this is related to P1 Ben.

    the ugliest car i have ever seen

    • Jc

      November 16, 2016 at 8:40 pm

      Jezuz, if that is the case you have never seen a gen 1 Daytona prototype or the Nissan lmp1 car from last year.

      • Bakkster

        November 17, 2016 at 7:04 am

        I still think the Nissan was the best looking LMP1 of all time.

        To each their own.

          If you mean the abortion from recently, yechhhhhh!

    Nice. Let see if finally a Mazda will win a race for good or only in the words of John Doonan

    Wonder if the AER engine will be up to the task of delivering reliable muscle at around 600bhp to compete with the Gibson WEC spec engine and the Cadillac motor. Let’s hope the AER motors stay reliable.

    The fin serves its purpose, but really stands out against the rest of the bodywork. It would be one complete sexy beast if it wasn’t required.

    And I hope that front splitter is strong. I suspect they’ll lose a lot of their front downforce without it, and contact will be best avoided.

    But overall, a very good looking car, and a good sign for DPi.

    • StueyB83

      While the Fin is unsightly and ruins the purity of the design in LMP’s – it prevents cars becoming flying wings when pitched sideways as has happened a great many times in the past.

      As an added bonus your sponsor gets a nice big advertising space!

      But your right, it looks like its just obstructing the photo 🙁

        Oh I thought he was talking about Fin from Sharknado…

      • terry jackson

        November 17, 2016 at 11:18 pm

        maybe a clear plexiglass fin would be more appropriate.

    Front end looks like the Peugeot 905 from 1993 except for the grill work and giant spliter.

      Thanks, you’re right on it…i knew i had seen that nose somwhere before

    with only one Mazda-Riley/Multimatic team the BoP will also include the drivers. they struggled last year with a great BoP. IMSA’s got their hands full this time…we’ll see if there last two years of experience has helped them quicken the BoP process and its accuracy…

    Looks amazing. The fin is the only bad thing and they really need to be optional… The fin didn’t solve any problem as shown by Anthony Davidson’s flip at Le Mans. The fins are totally pointless and ugly

    • N8

      November 17, 2016 at 9:58 am

      That is not true. Data proves that force required to “launch” a car with a fin is significantly higher than one without and it’s now 4 1/2 years since the last major airborne incident.

    • Dave N Snowhawk

      November 17, 2016 at 5:56 pm

      How ’bout they make the fins out of a clear material. Maybe less noticeable, maybe not

    Shame it cant run in LMP1 in the WEC with the AER V6 Turbo used by CLM etc, then at least it will seen by the World. (Obviously in Privater hands) TV Coverage of IMSA races is very poor in Europe these days.

    • Fabio

      November 17, 2016 at 5:19 am

      Actually it could race in P1 with the AER V6 Turbo. The chassis is P1 homologated, and obviously so is the engine.

      • Larry

        November 19, 2016 at 3:20 pm

        I know it’s P2 homologated. You sure it’s P1 homologated?

  15. Max

    November 16, 2016 at 5:48 pm

    Beautiful. So ACO/FIA, with LMP1-L seemingly dead in the water and Audi gone, why not invite the DPIs?

  16. #1 fin hater

    November 16, 2016 at 9:23 pm

    dumb ugly fin

    • Rohan

      November 17, 2016 at 4:35 am

      I’m still with you on the fin, I hate them as well.

  17. JamieR

    Looks evil-I like. Mazdas always look the part. Personally I don’t mind the fins, although I do wonder if they make as much difference as they are meant to.

    I’ll be honest i was dreading what the dpi’s would look like but that is a pretty awesome looking. I hopecthe rest look similar.

    Looks good except the strange front wing – do they expect snow in Daytona in January, so that they fitted a snowplough?

  20. Jenner

    November 17, 2016 at 3:35 pm

    Hmmm, doesn’t look like a Miata to me.

    What styling cues are they reaching for?

    • Larry

      November 19, 2016 at 3:22 pm

      Didn’t realize it was supposed to look like a Miata.

  21. Larry

    November 19, 2016 at 3:26 pm

    Anyway, looking forward to seeing them and the other DPis at Daytona on Dec 13th and 14th on the mandatory test days.
