Nissan GTR LM Nismo Confirmed for GT Academy Final!!!

[coryclifford]

Not sure he was asking what it meant, but http://en.wikipedia.org/wiki/Joule#Megajoule

More Joules will be feeding those electric motors more juice to get them going faster.

Electric motors are better at torque than power. The engines are better at power than torque. Mix the two and you get a very fast car from 0 and when the engine takes over, they can only go so fast. Then there's the aero package limiting speeds also. Nissan did a lot of work to make their car slippery and thus fuel efficient and that was the basis on their front motor approach. Eliminate all the things in the back to allow a better under tray, among other things to be more slippery, hence the higher top speed.

Am I missing something or does more MJ equals less top speed?

In the theory, according to the equivalence sheet between the electric / thermic MJ equivalence, yes, more electric MJ means less top speed but more acceleration. So every team has to do a compromise. By the end the theoretical value from the equivalence sheet must give an advantage to the team which chose more MJ on a flying lap. But it's much more difficult to have a reliable car with a powerfull hybrid system.

Thanks for the clarification 👍

MGU-K: motor generator unit – kinetic

MGU-H: motor generator unit – heat

ERS: Energy Recovery System (referring to the unit as a whole)

MJ: Mega Joules, so 1 million joules.

Joule: unit of measurement of energy, knowing that 1000 joules = 1 kW

(so 1.34 hp over a second), 8 MJ = 10.738 horsepower over a second.

 

[theteacher1907]

Not sure how long each hybrid class is allowed to discharge/use ERS system per lap.

 

[Beau Albert]

Its bugging me that i can now drive it, its in my game files..... its finally here!!!
But i can't have it for another couple of hours

I can't wait to drive it either... I'm busy at work today so it wouldn't have mattered anyway but am free tomorrow until the night (on a night shift) so most of my day will be spent in the GTR

 

[Harley45]

I'm just hoping it will sound epic an not like a vaccum cleaner

 

[vticoupe]

I still don't know why People claim that there will be a new Track for round 4

I quote myself, for obivious reasons...

The joule is an unity which measure the energy you can store. The watt is an unity which measure the speed of the energy when you realease it. So 1W = 1J/s.

In LM, the rules limits the fuel flow which means it limits the power output of the thermical engine. But it also limit the maximal energy amounth you can recover on one lap (by every kind of ERS: MGU K and MGU H). But the rules do not limit the way you release this energy. So depending on your hybrid engine you can release the recovered energy with more or less speed so with more or less hp.

For exemple in LM, the fuel flow vary around 90 kilogram/hour depending on your energy recovery class which means around 550hp with the thermical engine. The rules also limit the fuel you can use on one lap so you can not use this thermical engine at full power every time.
For the hybrid system, the maximal power is not limited so you can reach up to 1 000 000hp of hybrid power if you want. But there are some issues such as the way you can release this energy, the way you pass it to the ground, the way you store it, the way you recover it, the weight of your system, and so on... The rules only limit the energy you can recover on one lap. The power you can get from it and the time you can use it depends on the comprimise you choose. A car that has 0,5MJ to release can develop 1kW (1.35hp) for 500s, or 100kW (135hp) for 5s or 500kW (680hp) for 1s.
Cars with a kinetic flying wheel (GTR LM Nismo, Audi R18 from '12 to '15) can not store any energy for a long time due to friction. It's the same for the car with cars who store the energy recovered with a super capacitor (not sure of the name in english) such as the TS030 and TS040. The Porsche 919 store its recovered energy in a battery pack which can store the energy for about one lap.
So when Audi, Toyota and Nissan must release the energy recovered at every accelaration the Porsche can store the energy during one lap to release it on the following. It's the reason why 919 beats all the other car on qualifying sessions. Indead the Audi is expect to have around hybrid 400hp, while the Toyota must have around 450 / 500, the Porsche about 700hp and the Nissan only 200 or 300hp while they plan to develop 1100 hybrid hp for next year.

For a comparison, F1 can recover 2MJ on one lap and can only develop 120kW (160hp) with their hybrid system, while they develop about 650hp with their thermical engine (fuel flow limited to 100kg/hour).

 

[BATHURST 1000]

Good sound:tup:

 

[DarthMosco]

the model is not up to date

mirrors are in wrong place, no stop lights on the spoiler, no side light near number

 

[NW48]

Wait. In @BATHURST 1000 's video the number is #23, in the above screenshot, it's #22.

Maybe we are getting all 3 or just the 2. Food for thought.

 

[Downhill Dino]

All those changes happened at most a few days ago. What were they supposed to do?

I highly doubt they could've done a remodel of the car in 24 hours.

 

[NW48]

There's also nothing to say that's the final model. PD could still make a few minor tweaks before then.

I don't see any reason for them to change it.

 

[NW48]

I don't see any reason for them to change it.

I agree. But I'm just putting out there for any hopefuls.

 

[Downhill Dino]

I wouldn't doubt them giving the car an update somewhere down the line. Wouldn't doubt it being another car entirely either, or at least it might have to as its present form doesn't hold the same 8MJ system anymore and the like.

Whats the in game car have?

long before a few days ago, they are changes required in order to race in the WEC series, but I can understand that PD had modeled the car months ago

The car hasn't run in any WEC event. The wing lights were added around a week ago, the mirrors were deemed illegal mid-afternoon yesterday.

Illegal yesterday? I would think they fixed that longer ago. Considering that they attended test day yesterday.

 

[Downhill Dino]

The 8MJ part-time AWD system I'd imagine. The real car currently of course is running full time front wheel drive with 2MJ also to the front if I recall correctly.

Really? God, I'm having a blonde day today. Looks to be an in-game shot on first glance though, if I'm honest.

They were initially passed by the scrutineers.

I thought it was in game too. mostly because of the way he said it, "the model is not up to date". But I am actually blonde so.... derp. lol

It's currently available in GT6 right? or is it held back for 1 day?
