JDC-Miller Motorsports has confirmed that it will join the DPi ranks of the  IMSA WeatherTech SportsCar Championship in 2019.

The Minnesota-based team, which currently runs two Oreca 07 Gibson LMP2 cars, will switch to a pair of Cadillac DPi-V.Rs for a full-season campaign next year.

The announcement means JDC-Miller will remain in the top category of the series following IMSA’s decision to split its Prototype class into separate DPi and LMP2 classes.

Sahlen’s Six Hours of The Glen winner Stephen Simpson has been slated to drive one of the Cadillac DPis, while the remainder of the lineup will be revealed at a later date.

Simpson and co-driver Mikhail Goikhberg currently sit fifth in the Prototype standings following their second-place finish at Road America last weekend.

“When we first started our IMSA WeatherTech program in 2014 we knew our goal was to work with a brand like Cadillac,” said team co-owner John Church.

“We feel strongly that we have found the best possible partner and look forward to adding to the incredible success Cadillac has already enjoyed in IMSA.

“We can confirm that Stephen Simpson for sure will remain with the team for 2019 since we had an option to continue with Stephen.

“After his performance this year, there was no question that he will be in the lineup in one of JDC-Miller MotorSports Cadillac DPis for next year.”

The team expects to take delivery of its first car in September with a view to launching a testing program in November following the end of the current campaign.

The Cadillac DPi, which is based on the Dallara P217, has won ten races since its introduction to the championship at the start of 2017.

It has also won the last two editions of the Rolex 24 at Daytona and took Wayne Taylor Racing to its maiden IMSA WeatherTech Championship title last year.

“We welcome the JDC-Miller team to the Cadillac V-Performance family,” said Matt Russell, marketing manager of Cadillac Racing.

“Their performance with the LMP2 cars has been impressive and we look forward to them joining the grid with their two new Cadillac DPi-V.R cars at Daytona in January.”

    Damn. Two caddys???? They wrote a huge check.

      TWO fast peddlers in Simpson and Goikberg,to replace retiring Fitipaldi and Barbosa,as GM hits the TRIFECTA !

        Fitiplaldi yes, Barbosa? I don’t think so, I follow sports car news fairly close, I don’t recall seeing the news regarding Jaoa Barbosa announcing retirement

    Huh, not what I would have guessed. The Cadillac is top dog in DPi I guess, so it makes sense, but I would have hoped for a different if not new manufacturer. The DPi’s like all prototypes look pretty much alike, but now 5 Cadillacs?

    • Kirk

      August 9, 2018 at 10:53 am

      The problem is it appears the Caddy is the only customer option right now. If Mazda or Acura or Nissan were to come out and declare their cars available then potential customers might have more options.

      • Old Trombone

        August 9, 2018 at 10:56 am

        Mazda just “came out”

        • Robo

          August 9, 2018 at 1:04 pm

          Mazda hasn’t “come out” with anything yet. They said they’re looking into it for the next season.

          • Mark - Toronto

            August 9, 2018 at 3:04 pm

            They have apparently just clarified that they are not in a position to do anything for next year.

    • Tyler Sanders

      August 9, 2018 at 12:26 pm

      How do all the prototypes look pretty much alike?

      • Dave

        August 9, 2018 at 12:50 pm

        Really? I mean I can tell the difference between an Oreca and a Ligier, but they look essentially the same because they have to but the regulations. The same thing applies to the DPis – they are based on P2 chassis after all. I mean OK they have modified front clips and Mazda has done a better job than most at differentiating its car from the rest, but still any modern-day prototype has the same silohette from P1 down to P3. In GT from a Ford to a Porsche to a Corvette to a Lambo – the differences are much more manifest. Maybe that’s just me though…

      • Matt

        August 10, 2018 at 1:06 am

        Because there is one shape that works the best for the given regulations

    • Steven

      August 9, 2018 at 4:47 pm

      The other cars, (Mazda, Nissan, and Acura) are exclusive contracts to only one team.

      Nissan is most likely not even around next year without the Ed Brown/Patron money. And Penske is not gonna allow a another team to race against his team in the same equipment.

    Looking forward to the CPi class in 2020.

    • Slicks in the wet

      August 9, 2018 at 11:31 am

      Well. Mazda would instantly be better.

      Acura might as well.

      Cadillac DPis for ALLLLLLLL!!!!!

  4. Old Trombone

    August 9, 2018 at 10:56 am

    I think there are only 4 Caddies going around. This makes me think SDR are finished, and WTR are changing to a new brand, perhaps a Lamborghini DPi, now that Lambo have decided not to do GTE?

    • Andrew

      August 9, 2018 at 11:43 am

      I’ve wondered that but it’s been a Cadillac in house rule of they can only support 4 cars. I’d assume SoD is done after this season so that’s one car but where’s the next one it are they going to 5?
      I’d assume all new cars being built for them, possibly buying the SoD car but I’m thinking at least one new car from Dallara.

      Now you bring up a good point about Lamborghini. Atherton says no new interest likely but he always said yes new things coming and nothing happened so maybe he is opposite guy? Too much Costanza as a role model for him maybe?

      • V-PWR

        August 9, 2018 at 1:17 pm

        WTR has a complete spare car and a complete rolling chassis so theres more out there than jus SoD’s.

    • Pete

      August 9, 2018 at 11:46 am

      Things more likely than this:

      I replace Misha as Simpson’s co-driver.
      Sean Heckman smiles.
      D3+Transformers Racing shows up to a race.

      • Tim

        August 9, 2018 at 12:15 pm

    P2 car counts for next year?

    – 1 CORE
    – 1 Performance Tech
    – 1 PR1 (though with two pro drivers I’m not sure how that will work)

    – 1 BAR (if they show again)
    – SDR (maybe they drop to P2?)

    • Matt

      August 10, 2018 at 1:08 am

      That’s fine

  8. Michael Sorensen

    August 9, 2018 at 2:05 pm

    I think it is stupid to split DPI and LMP2…. Change one ok class to two weak ones….

    • Andy Flinn

      August 9, 2018 at 9:40 pm

      Muchael, it’s only OK now (I assume because LMP2s are winning) because the DPis are restricted.

      Next year, IMSA can take the chains off the DPis. No longer will IMSA be forced to slow down the DPis to match the Euro-spec LMP2s.

      JDC-Miller, the only IMSA LMP2 team that has really expressed a consistent interest in racing for overall wins, has now switched to DPis for 2019.

      Very cool!

      Next year, the IMSA LMP2s can preserve their global spec and fight for class wins – just like the global spec LMP2s do in the WEC.

      And for those who want to whine about Caddy domination in DPi, has there ever been any doubt who would, is and will continue to dominate the top class in the WEC “super season”?

  9. JaymondoGB

    August 9, 2018 at 2:15 pm

    Race full of dinosaurs…,what a shame the opportunity of DPI will eventually turned into a one car class just like LMP2 has done in Europe with the Oreca. Still at least the Gibson V8 is modern.

    • Blaneysellstrashbags@Ring24

      August 9, 2018 at 3:54 pm

      I would wait before making that judgment. Its my understanding that once the class is split next year the DPi cars will be turned loose so to speak. I am wondering how much the Penske Acura has been dialed back as compared to the caddys. There has been talk that once all the DPi cars are allowed to race some of the teams that have been running behind the caddys will finally be able to show their speed. And lets not forget Ford is on their way in 2020 along with a couple other rumored makes.

    • Steven

      August 9, 2018 at 4:52 pm

      There are 16 LMP2 entries in the ELMS for next weekend. 8 Oreca 07’s, 4 Ligier’s, and 4 Dallara’s. That’s fairly diverse.

      The WEC obviously has all but one team with a Oreca but all those teams have been with Oreca since the 03/05 days. So they have stayed loyal to the company.

      You can’t blame the teams for not wanting to pick the best chassis on the grid.

    • Andy Flinn

      August 9, 2018 at 9:47 pm

      JaymondoGB, you obviously don’t watch IMSA races – notably Sebring and Mid-Ohio.

      DPi is not a one car class.

      It never has been and never will be.

      On the other hand, the Gibson is a spec engine mandated in every single LMP2 car in Europe.

      But you’re right. The Oreca still dominates WEC LMP2.

  10. Steven

    August 9, 2018 at 4:44 pm

    So Hyundai said no to the DPi program I’m assuming.

    This is why rumors should not always be published all the time as sure things.

    • Robert Stephens

      August 9, 2018 at 4:51 pm

      Where did you see they said no? Very possible they are waiting for 2020 and not wanting to rush into anything.

      • Steven

        August 9, 2018 at 4:58 pm

        Unless Core gets a call, there are zero solid prototype teams that a factory team would want to be associated with. ESM would be another, but without Brown backing the company, they may not even be around next season. Hyundai going into the series alone as a startup would be a bigger disaster than the Riley LMP2.

        • Tim

          August 9, 2018 at 7:51 pm

          ESM and Ed Brown are not going anywhere.

    • John

      August 9, 2018 at 8:46 pm

      The Hyundai rumor came up because Stallings thought his relations with the company afforded the possibility.

      Of course, that probability was slim, but it was played up in a story anyway, and the rumor repeated again just six days ago. Given that the GM probably didn’t just materialize overnight, never mind within the past week, draw your own conclusions as to the reliability of such stories, and their headline writers. JDC wasn’t negotiating with GM while starting a Hyundai program at the same time.

      Caveat emptor.

      • Andy Flinn

        August 10, 2018 at 12:36 pm

        John, it wasn’t a “rumor.”

        Even though you choose to ignore them, Bob Stallings has SOLID ties to Hyundai through his car dealerships and racing programs.

        Anyway, neither Bob Stallings nor the writers of any of these stories ever promised you a Hyundai DPi program.

        But yes, definitely beware of anything posted on this message board.

    • Andy Flinn

      August 10, 2018 at 12:29 pm

      Steven, Hyundai was just one manufacturer (previous relationship with Bob Stallings through dealerships and a PWC GTS class racing program) that Bob Stallings was considering for a possible DPi program. That was clearly explained in all of the articles.

      NOWHERE in the reporting was it written that a Hyundai DPi program was a done deal. So I don’t know what “rumor” you are referring to.

      Bob Stallings also has a relationship with GM dating back to the Gen 1 Riley-Pontiac Grand-Am DP double championship-winning program (2007 and 2009). Hence, the two-car Cadillac DPi program obviously makes sense.

      You act like this news is a letdown.

      The fact that JDC-Miller have announced two Caddy DPis for 2019 should be cause for celebration not the subject of scorn.

      • Steven

        August 10, 2018 at 4:50 pm

        I’m just saying that rumors should not be always be published immediately unless there is absolute solid evidence that it is happening.

        Sportscar racing has a hard enough time finding new blood and getting people’s hopes up on fairy tail articles shouldn’t be done. Hyundai has done pretty well in the WRC and would’ve been an interesting what they would do as they do not have much of any sportscar racing.

        • Andy Flinn

          August 10, 2018 at 6:12 pm

          Steven, you still haven’t told us what the supposed “rumor” is.

          Are you questioning that Bob Stallings has ties to Hyundai?

          Are you questioning that he discussed putting a DPi program together with Hyundai?

          I don’t recall reading anything about Hyundai’s official position on a DPi program. Have you?

          If this was a “fairy tale” article it certainly had a happy ending (two new Cadillac DPis for JDC-Miller for 2019).

          • Steven

            August 10, 2018 at 7:34 pm

            The rumor wasn’t on this site as far as I know, but from another racing site.

            It was Marshall Pruett who wrote the non-sense of the rumor in hopes a 5th manufacture (Hyundai) would step in with JDC. In a fantasy land, I wish every manufacture was in sportscar/endurance racing, but that just isn’t in the cards. For him to come up with a bunch of dribble with nothing to show for it is why so many people are tired of hearing about all these manufactures coming into “DPi.” From Ferrari, Bentley, Mercedes, Audi, Porsche, Hyundai and others.

            Articles based on “hopes and fantasies” should not be written and published on major racing sites.

  12. John

    August 9, 2018 at 8:59 pm

    So in 2019, GM with have five bullets in its gun (six, if SoD finds the funding) and HPD will only have two.

    Mazda can’t afford to spend lavishly, and ESM is a privately-funded program, so they understandably remain smaller.

    But I’m curious as to what HPD’s thinking now. Did they give Penske too good of a deal (exclusivity), and did both of them expect too much? Because with only a couple races remaining in the season, CORE has won more races than Penske. I can’t imagine that goes down well in Santa Clarita, Gardena, or Mooresville.

    • Andy Flinn

      August 10, 2018 at 12:43 pm

      John, I don’t understand how the results would be any different this year with more Acura DPis.

      If the Penske dream team and their star all-Pro driver lineups can’t win with two cars….

      The DPis aren’t winning because IMSA was forced to peg them back to match the fixed performance of the global spec LMP2s.

      Next year, when the chains come off the DPis, it will be a whole new ball game for Acura and the other DPis.

      • John

        August 10, 2018 at 9:08 pm

        Come on Andy, don’t be obtuse.

        You can’t blather on relentlessly about how Oreca domination is bad for the LMP2 class yet ignore how an unbalanced, Cadillac-heavy field is neither healthy for IMSA nor as interesting for fans.

        They both enjoy an advantage just from strength in numbers alone. If a Caddy or Oreca falters during a race, there will be others to pick up the slack.

        This has nothing to do with DPi/P2 or BoP. IMSA is in no better position the FIA when GM will field at least half the class in 2019.

        People like to rip the FIA for being on Toyota’s leash but they’re foolish if they can’t see that IMSA is just as vulnerable.

      They’re doing way too good in GTE to care about a small time prototype side gig

        August 10, 2018 at 12:48 pm

        Mattie G., you’re right. Porsche really didn’t need that LMP1 side gig. LMP1 is dying anyway.

  14. JeffB

    August 9, 2018 at 10:32 pm

    I wish all IMSA teams frankly had their shit together like JDC/Miller Motorsports.

    They buy a P2 on the promise they could compete for overall wins. In 2017, they compete for overall wins.

    In 2018, they announce they want to expand to two cars. They not only expand to two cars, but add a genuine primary sponsor in Gainsco, and win a race overall.

    For 2019, rules changes are rumored and then announced that takes their cars ability to win overall away and *five days later in early August* they announce their plans for next year to move into the DPi class and name their lead driver at the same time.

    None of this showing up for some races to start the year and then skip a race here, and skip a race there and quietly fade away or suffer a crash that derails half their summer.

    Not JDC. Buy it. Own it. Run it. Fix it. Race it again. Win.

    I love this team.

      JeffB, you make it all sound so easy.

      Except, you forgot “sponsor/pay for it.”

      But I guess it is easy when we’re spending other peoples’ money.

      By the way, give Performance Tech a break. One of their team leaders passed away recently.

    Interesting, thought they would head the Nissan DPi route. Looks like no Ligiers left in the field next year with PR1 rumored to be switching cars for the rest of the season.

    • Steven

      August 10, 2018 at 7:42 pm

      Nissan is most likely finished.

      ESM is giving up the rights of the Nissan deal after Petit, and I don’t see any team picking up a manufacture that doesn’t really want to be there. Renault group is more interested in the F1 gig and smaller GT efforts for Nissan.

      The only way Nissan stays in is if United Autosport buys the cars. They have already said they are very upset about the class split and having to tell sponsors that they are no longer allowed to go for a win at Daytona/Sebring unless they are in a DPi for 2019.

    Whenever you go into Nascar’s playground, you’d better have Nascar equipment.

    Just as an aside…could the Caddy engine be put in an Oreca???
