Must say, from the testing footage it's a great looking field this year. Big fan of the PR1 livery personally too.
Totally agree, but perhaps ESM saw the writing on the wall for the Gibson engine, therefore ESM wanted a motor which is proven, lowly stressed and reliable from Nissan, who they seem to have forged good ties with over the past year, they certainly migrated well away from Honda, especially after MSR got the full blown NSX deal.

In testing the standard LMP2 route has worked a treat for Dragon-Speed and Rebellion.......but will they really go the distance for 24 hours?.....I really doubt it with the Gibson V8.....my money is on the Cadillacs for a win, and the ESM nissan should go the distance for a sneaky podium, on the basis that they are both low-stress engine options......being blisteringly fast in practice and qualifying means almost nothing for a 24 hour race.

If the Gibson can't last 24 hours then they really shouldn't have been given a contract to make engines for LE MANS prototypes! Surely that was point #1 in the specification for that engine and for the new cars?

(Sorry, those are fairly rhetorical points and it was historically an issue with P2s, I realise it's the first public outing for the engines and cars)

Yet the last few times it was run at LM, the 4.5 Gibson LMP1 engine didn't have major issues, and we have to remember the TMG 3.4 V8s that for sure revved higher than any of the Gibson purpose built LMP engines, though the TMG engine was developed from Toyota backing.

Though it should also be said that the Toyota V8 was a Formula Nippon engine that only ran sprint races until Toyota started running it in the Rebellion Lolas and the TS030.

I think you forget that it won the Suzuka 1,000km and the Super GT championship. It was jointly developed for Formula Nippon and GT500 so it was designed to do more than sprint races.

A 1,000km race is a sprint race compared to a 24 hour race.

If any of you guys are interested in video of the DPi's I did a small one from the weekend! https://www.youtube.com/watch?v=cUNGf3aeHGA Personally I'm loving the new Cadillacs, they sound awesome.

A 6 hour race is in no way a sprint event, compared to anything.

I think Nissan is a willing partner but not to the point of the others (obviously). So with the recent interview, I wonder if next year they step up support and the engine and it's components gets lighter or changed? And if it's ESM doing the bodywork, what is the chances that the lmp1-p rumor is true and they find a way to get the car over to the wec or LM?
They're sandbagging, Scott Sharp and Ed Brown went to the beach to work on their tan, and all the sand ended up in the cars.

50kg is a lot, and it affects performance everywhere. For BoP's sake IMSA could make it a rocket on the straights.

It's only 1/4 the distance of a 24 hour race. That's a sprint by comparison. NO, it's no small feat, but it's nowhere close to 24 hours.

On top of that, the Super GT engines do get repairs and rebuilds in between races.

This makes the Toyota engine's successful usage in a 24 hour race a genuine and very welcome surprise. The engines were NOT originally designed to run that long without maintenance. Proof that we shouldn't assume that an engine designed for purpose A isn't capable of purpose B, but at the same time enough of a difference to have concern about things until they actually DO the job.

As far as the Gibson, I expect teething issues at Daytona and Le Mans. But I feel they'll be ironed out for 2018.

That's good points but the engines are not fragile pieces. The new one's especially since they see multiple races with the same engine. It is not a huge task to make a reliable race engine from a fast one.

I wonder if the speed of the Mazda's was due more to it being cool, than them actually having a lot of power. If it's warmer like it will be in 2 weeks time they won't have the same pace.

I have been following the practices online and following the top speeds. I think the top speed of the Mazda was just one lap, it could be because it was driving behind another car, because average top speed was a lot lower as we can see on the analisys.

As a comparison, how reliable was the LMP2 VK45 Nissan engine when it was first used at Le Mans?

Top users finished 1-2 in class, 8th and 9th overall. One car retired with overheating, but that was driving slowly back to the pits after a crash which had also damaged the water radiator.

Doubt the stanchions for the nose will be green. They're gonna wanna make sure the GT-R shape is super noticeable.

I have to say, I see a lot of GT-R in ESM's effort. The GT-R is a big, hulking grand tourer, having its face attached to a tiny single-seater inspired Le Mans(/Daytona) prototype.

I don't think ESM's Nissan's are quite ready for the Daytona 24 I feel. I expect some reliability issues with them overnight. (as is the cases with other DPIs). Sebring they will be good though.

They've got a pretty great livery worked out to push the Nissan connection. Just wait. You'll be very happy.

Joest Looks To IMSA DPi For 2018 Comeback

The factories that are looking at prototype programmes are certainly looking here (in North America) and that’s what we are targeting. Audi is not on list of interested parties for 2018.
