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. |

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.

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

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. |

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 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.

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. http://www.dailysportscar.com/2017/0...-comeback.html |
