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.

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 :/ |

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. |

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. |

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'.

Lapierre missing Fuji. Hope to see him back for Shanghai.

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

Theyre not replacing him. At least not at Fuji. I think theres signs of a shakeup in their lineup for 2015. Imo, Nakajima Davidson and Buemi are the three fastest in the team. I dont know if theyll change lineup's, but they should be in the same car.

Lapierre and maybe Sarrazin will leave for next year. I really hope that if JEV doesn't get a F1 seat Toyota will sigh him. I feel that he may turn out to be better than Buemi even.

Personally I wonder whether we'll see Kamui Kobayashi get a drive with Toyota next year. I think after this year he's had enough of chasing F1, having been messed around a lot. He was part of the Toyota program for 6 years, they took him from Formula Renault to F1 and looked like they were going to give him a full season in 2010, before Toyota pulled the plug. Surely some kind of connection is still there?

Lots of his Japanese fans of his want him to join Toyota if he cant get an F1 drive. I hope he gets in at McLaren Honda, but if not, he should try to join Toyota or Nissan.

He needs to be at Toyota. Stick him in with Nakajima at Toms in Super Formula as well.

Unfortunately, Akio doesnt get to make that call on his own. Maybe a win @Fuji will change some minds!
