Surprised?

ligier-nissan ESM at 99% won't be in grid next year, and unlikely any other team will buy their cars without a confirmed nismo support.
About mazda dpi's, is still unclear if they are open or not for privaters, but don't think there's a long line behind their door .
Acura seems to want focusing only on the semi backed penske program.

Cadillac dpi is just the only option if you want to step in the main class.

Lmp2 guess will be some kind of faster lmpc next seasons, few entries and just teams looking for paying drivers.

DPI/LMP2 split downfall consequences....

As usual, Dallara wins while everyone else loses.

Going to be hard for one of those furrin' brands to win Daytona either.

It's great to have another car, but this could become like WEC LMP2. Might as well call it LMORECA and DPCADDY. Hoping there's more variety soon.

Well, really different circumstances.

In WEC, ligier and dallara are available for teams that wish to get them, but oreca shown a so clear excellence that made the 07 the teams first choice.

In IMSA basically cadillac dpi is the only dpi available

IMSA could solve this making this simple rule:
a manufacturer can enter, via private teams or official team, as many cars as it wishes for the first season but must to guarantee at least 2 available cars for requesting private teams for the following seasons.

Oh totally different circumstances, I agree. Not saying it's the same problem - more the result is the same. We end up with a half spec series.

Kinda like how LMP3 was until Norma made something good. You could buy a Ligier, a Ligier, a Ligier, or you could shoot yourself in the foot and buy a Ginetta. So really, you only had Ligiers.

Not the same cause, just the same outcome. But the plus side is another car is nice. Although the reality is we may lose the ESM Nissans. They're selling cars too, but that's just the Ginetta option. Why bother?

I wonder how much more it'd be to run the Nismo lmp1 engine in the back of the ByKolles instead of the GTR's? I think that'd be a big boost but who knows if IMSA would allow it or if any team could even afford it, on top of the entry fee.

There is both a Ligier and a Dallara in WEC LMP2 though. Not the most competitive teams but still.

Nismo-Cosworth V6 lmp1 sure is quite more expensive than a slightly racing upgraded GT-R road engine.
Not the best option for a class that has to keep costs comparable to lmp2 usage.

Beyond that, guess nismo-cosworth engine has been projected and developed to better adapt to fuel flow than dictated turbo pressures range.


Anyway.... why doesn't simply IMSA admit that making the split was the sh**test decision ever made and simply retcon it as it has never happened? surely JDC who just brought 2 new cars won't be so glad about that....

Yes, and there is Mazda and Acura in DPi It's a kinda semi-spec, purely through circumstance.

Regarding the Nismo engine, is the GTR engine overweight? The new GT3 car hasn't exactly been great so far. We know the car is overweight, but is it the engine?

Scott Sharp last year revealed that their ligier is overweighted compared to bop min. weight.

Guess that GTR engine + cooling systems + chassis parts made to fit the engine make the car discreetly heavier than how it should be according bop.

I'd list ESM as LMP2 Maybes as well - I don't think they'll be going away, I think it's just a question of whether they'll be running Nissan DPis or Ligier P217s.

I was pretty sure they said they were overweight in terms of having to remove ballast and that gives them unfavorable weight distribution, not that the car is heavier than the 930kg it's supposed to run. But either way, removing ballast because the engine is heavy is not ideal because that ruing the balance of the car and could cause handling issues.

Well remembered!

Quote:
Dumas said weight distribution has also been a key difference between the two prototypes, with the production-based Nissan powerplant some 50kg heavier than the normally aspirated Gibson GK428 V8.

While the JS P217 carries ballast to meet the 930kg minimum weight, Dumas admitted the Nissan DPi is currently slightly overweight.

“It was a challenge but of course at the moment we have something to learn,” he said. “We have to work on our side and especially on NISMO’s side to get a competitive weight.

“When you talk about a 50-kilo difference, especially on the rear, and when you look at the engine, the weight is at the worst place. It’s very high. So, the weight distribution is so different.

“I’m expecting the LMP2-spec cars to be very fast,” Sharp told Sportscar365. “With the lack of the long straightaway, it’s really going to appeal to a car that’s 100 pounds lighter than everybody.

100 pounds = about 45kg

Anyway considering that nissan gtr engine is in the range of >620Nm for most of the low-mid rpm range; basically almost +100Nm than torque peak of gibson engine; guess is better to have a slightly heavier but balanced car IMHO.


BTW this season nismo tried to introduce lighter parts for the ligier-ESM engine but wasn't a great move.... they came back to heavier but more reliable old parts.

Anyway, about 2019 season, after running and winning in main P class for years, it's weird see them in lmp2 class just to be the best of the rest.

But ESM does have a few rich guy AMs in their PC series seats who seem to do well there, the step up may be too much in terms of talent and cash but who knows. That could help them field Ligier versions of the car and hang in LMP2. Unfortunately I think that leaves Pipo out BUT there are 3 new Caddies in the field and he's FAST.

I can immediately see Derani as a top choice for the Juncos Cadillac. If not that. Wonder if Corvette needs a shake up in their driver line up. He is certainly capable in GTLM too as we have seen him drive Ferrari and Fords before.

Yep. Can't understand why do teams like PR1/AFS decide to change cars in the middle of the season. OK the Oreca is a bit faster than the Ligier, but considering the very poor operational performance of the team (and drivers), shouldn't they work on their own issues before buying a new car ?

Like SoD last season, maybe they just rented the ligier.
Considering that when a team buys one lmp2, basically purchases 1 carbon monocoque + spare parts x2 cars, it's quite unlikely that a gtl-am oriented team like PR1 may be able to purchase 2 fresh cars a season.

My bad: PR1 had the ligier since early 2017. Anyway.... oreca won races, ligier not. Guess the reason of the car swap is simple.

Ligier may not have won any races this year, but it was still the first LMP2 to beat the DPis in IMSA. I honestly don't think the performance discrepancy between Oreca and the others is as big on US courses as it is on European courses.

Obviously PR1 either disagrees or there's some unknown financial incentive involved.

Daily Sportscar seems a little less prone to "Big Scoop! breaking News! Pure Speculation!" articles than some other publications.

This one had a fairly clear quote from the team owner:

"Team co-owner Richard Dean, whilst making it clear that the team were not in support of the class split, also made it clear that United are now actively pursuing a 2020 DPi programme:

'The class split does not work for us, we are not interested in contesting in a class that won’t be in contention for overall wins. If we could be in a DPI next year we would be, but only if the conditions are right and, at present we aren’t there, and it’s now too late to do that properly for next season, so our plans are looking at 2020.'"

Putting together an entirely new program using an entirely new car, all the spares and back-ups, learning how to make it work and such .... while still running in other series ... I could see where that would be a reach.

basically the team wants to run in the top class but right now the way forward isn't looking that clear, but the team is sure that given enough time a good package could be put together.

Pretty clear UA doesn't plan to run Petit .... but we will certainly see them if they are there.


"Considering" articles, to me, are the ones where some team principal says, "Well, that's not on our radar but of course, we will never entirely close the door ... who knows what might come down the road," only to have the headline "Team XX Considering Move to Class Y" slapped on top of a bunch of BS built around the quote.

In this case, the reporter reported exactly what the team principal said .... how is that not good reporting?

Would we all be happier if all the sportscar sites all said "Go to the first race of next season and see for yourself who is on the gird. Don't bother us just because we talk to the teams and know their plans."?
