Remaining P2 cars undeclared -

Core Autosport - Oreca 07
AFS/PR1 mathiasen Motorsports - Ligier JS P217
Perfomance Tech - Oreca 07

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 NISMOs 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. Its 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.

AFS/PR1 basically confirmed today the 2019 season in LMP2 using an Oreca.

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 ?

Here you go Mr Ligier you can have your car back now in a bag of bits, that was a fairly hefty whack at Road America

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.

United Autosport is sitting out 2019. But will be back in 2020 with a DPi based on a Ligier.

That's not confirmed though. It's another one of those 'considering' articles.
