Sounds more like heavily developing the current model, in the way Audi have with the R18.

GasperG has a lot of promise if they can keep it on the circuit!
Fuel allocation for 8MJ class have changed, maybe there is a benefit even if you can only get 7 MJ to compete in 8 MJ class, that certanly wasn't the case last year.

Its sad, but Akio Toyoda is one of only a few within Toyota that likes racing.
Aren't the majority of the companies on the car technical partners? And then companies like Denso are part owned by tje Toyota Group anyway. I guess either way it's still benifical for Toyota in whatever way.

The last past in bang on - when I was in Japan, most of the stuff I was hearing/reading about Toyota was that Toyoda-san was largely opposed in the board room about the motorsport ventures of Toyota, both offical programmes and his personal racing inclinations. Sad really :/

In order for the 8 MJ option to be viable, Toyota will apparently need to invest quite a bit in making the car lighter to accommodate for the additional weight of the 8 MJ hybrid architecture. Besides, it is unclear if Toyota can stick with the current supercapacitor units. According to reports, they may need to look for alternate energy storage solutions, which may be risky reliability-wise.
There has to be ways of saving weight in the car and probably on the hybrid side. The switch to a battery unit would only be beneficial if it was a gain over the capacitor. Nothing so far says the capacitor cant do 8mj, only that itd compromise weight. Well thats probably the balance of the car being affected rather than overall weight.

If they do go 8mj, thats a 33% increase in electric power. The total petrol fuel flow decreases 89.5-88.5kg/h or a 1.1% decrease. Petrol energy drops from 62.6-62.0mj/l or a .95% decrease. But total energy goes from 68.6mj/l-70mj/l or an increase of 2%. Definitely worth it if you get a total increase of 2% total power per lap. If 6mj=480hp, is it 8mj=640hp?

Btw, heres a great read on what TMG is and what it features. An amazing place, very detailed.

It depends on many factors. First is the power density of the supercapacitors. If your 2 MGUS are ready to produce this amount of power, than your storage system has to do it too. Second important factor is traction. Are you able to get this incredible amount of power on the track without spinning your wheels ?

From a simulation point of view, it would absolutly make sense to increase the power output from your hybrid system, instead of goind for longer boosting times. Because the more energy and the more you can release it below average lap speed, the better your lap times will be.

If you go down to 8 MJ, your power outpot of the ice will only drop by ~ 6 hp, while you have to coast the same amount as you do with 6 MJ. But the most interesting thing would be, how much can they increase their thermal efficiency of their engine ? From what i understand, die bfsc is gone since Le Mans. That would mean, that you can increase the thermal efficiency of you engines. By doing that with 1,5% and going up to 8 MJ, this would be good for a decrease of 2,5 secs a lap around la Sarte. this years pole time was 3:21.7 and fastest lap was a 3.22.5 done by Andre Lotterer.

So it looks like that we maybe can get back the crazy sub 3:20 lap times around La Sarthe

I think that releasing the whole 8 MJ is at least of your problems, the problem is collecting all of it through kinetic energy, that means 480 HP (8MJ=640 HP) generating power. I don't think they release all the energy at full power all the time, efficiency of electric motor drops when you go over it's power rating and released energy (for MJ class) is measured before electric motor. They must use some kind of best balance between motor efficiency and best lap time. I may be wrong and efficiency doesn't drop that much and it's still better to use it all as fast as possible, who knows?

And I think it was mentioned in an interview that electric motors are not the bottleneck of power, the supercap (maybe even inverter) is.

They shouldnt have a problem with collecting the energy with both axels recharging from braking. Theres huge forces involved in stopping these cars. Im not sure the actual figure but Toyota was asking to use the hybrid freely before, seems they aren't concerned of its performance in output or storage. Remember they have two electric motors so they can split the power output between them. In 2012 they said 300hp on the rear axle. If they kept that the same then maybe its 180hp on the front axle. Would it be a problem to split 150hp more between them?

I would love to see the actual picture that was used by Antonio as a basis for this illustration.

In view of the recent "clarification" (well... sort of... it's not a clarification as a matter of fact ) issued by the Endurance Committee, it is apparent that these "extreme" aerodynamic solutions (as also adopted by e.g. Porsche and Audi) will reviewed during the next TWG, and I would not be surprised if these aerodynamic "brake scoops" will be prohibited starting from next year.

Looks like you are going to be right.... Too bad, that was some easy, good DF!

I dont think theyll be banned, actually. I think theyll be written into the rules to allow for a certain area of freedom. Vasselon even spoke of next year's car having "different underbody aero". This year's car didn't feature the brake scoop wings, and it was Toyota who asked for clarification! So either they're all for it or against it. And if these on the Toyota are 'new' then seeing even Rebellion has new vanes, Im guessing all lmp1 teams are for it. All that development wasted would be a shame.

Toyota's had them in some form since the start of the season. Refer to the WEC Prologue slow-mo video on Dailymotion. Toyota had them, though they weren't as aggressive as what Audi and especially Porsche have/had.

They've always had underbody aero devices like the vanes, but not the 'brake scoop wings'.

A real shame. I hope there is nothing too serious on the personal side that prevents him from taking part to the Fuji race.

What about Conway then ? Isn't he available to possibly replace Lapierre for the Fuji race ?
