All of Toyota TS050 Hybrid magazine's report
*Engine (2016 spec) -TS050 engine (2.4l,V6) development began in January 2015. -The reason for switching to turbo engine is that it is easy to adjust to changes in weather conditions and that the friction is low due to the low rotational speed. -The reason for choosing V6 is that it is easy to make a stress mount. -2.4 liter displacement was determined from an efficiency standpoint. -6-cylinder was decided to distribute the load and to differentiate from Porsche. -Prototype production period is 8 months, first burning is October 2015. -Because the development period was short, the development knowledge of RI4A(SGT/SF engine) was used. *Engine (2017 spec) -2017 spec TS050 engine is completely different from 2016 spec. -In order to improve performance, the length of the engine has been extended. -Since the width of the bearing was expanded, the total length became longer. -Initially, the displacement was reduced from 2.4 liters to 2.1 liters. -This is due to the simulation results that reducing the displacement reduces the friction, allows the turbo to be used in the high-efficiency region, improves intake and exhaust losses, and increases the total output. -It was March 2016 that Toyota decided to reduce the displacement. -However, the knocking problem cannot be solved, and the displacement is returned to 2.4 liters in November.30.2016. -Instead, a new combustion concept (pre-chamber) was introduced. -In 2017 specs, alternator was abolished and switched to DC-DC converter (815V to 12V, Made by Magneti Marelli). -The DC-DC converter is half the weight of the alternator. |

*Front MGU (Aishin AW)
-TS050 has a front MGU inside the monocoque. -The gear ratio is fixed, but there are two types: high-speed LM/Spa spec and the other. -TS050 adopts SiC for power device. -Cooling is oil-cooled for both gears and motors. -2014 spec has an MGU below the differential, but the 2016 spec places more importance on aerodynamic performance than the center of gravity, and the differential is above the MGU. *Rear MGU (Denso) -2016 spec was fastened to the bell housing at 12 locations, but 2017 spec was tightened at 6 locations to reduce weight (Dozens of grams!). -Cooling is oil-cooled, and the feed pump is mounted on the gearbox. *Lithium ion battery -In 2017, the maximum voltage was increased from 750 V to 815 V, and the operating temperature was increased from 60 degrees to 85 degrees. -It has been operating at about 90 degrees since 2018. -By reviewing the electrolyte, it became a cell that deteriorated only a few percent even after running 10,000 kilometers. -Buemi says that capacitors use full boost or don't use them, but in batteries, there is a chance to use them 10 times per one Sarthe lap. *Engine bench testing -Higashi fuji labo conducts an evaluation test by simulating the rear MGU + engine bench and the front MGU bench in a separate room. -The standard for engine durability tests is 10,000 km. -In addition to the racing speed simulation test, the system was optimized by conducting 70 types of irregular situation simulations for 2018. |

Supplement
*Engine -2016 spec engine follows the technology of the V8 era gear train and the arrangement of auxiliary equipment. -2017 spec engine is larger than 2016 spec engine, but lighter. -The oil catch tank, which was installed behind the gearbox in the 2016 spec engine, is installed between the V-banks in the 2017 spec. *Monocoque -Total of twelve TS050 monocoques were produced in three years from 2016. -If it is used normally,it can be used more than 40,000 km. -The TS050 monocoque is only 5% lighter than the TS030 monocoque. This is because FIA safety standards must be met. -The monocoque of #7 that crashed in the LM24 qualifying in 2019 can be repaired and reused. |

*As for hybrid control, initially, during FCY, the engine was regenerated by the MGU and applied a load to the engine.
This is because the engine can run more smoothly when the engine is loaded at low speeds. However, since the battery charge state became full, there was a difficulty that could not be regenerated by braking at re-start. Therefore, finally, the control to pause one bank of the engine was adopted. |

Interesting, so under FCY the TS050 is essentially a straight four hybrid.
Would be a good advertising aspect, I would assume. |

Thanks for the translation and information Japanese Samurai. Good stuff in there revealed. The SiC being used (assuming the semi-conductor) is something that I was interested in because of their benefits and the fact Toyota was looking to use it for their road hybrids. That seems to be on the back foot now because of a supply shortage but great to know. |

Toyota team director Rob Leupen conceded that one of the weaknesses of the LMP1 handicap system in its current form is its tendency to create dramatic performance swings from race to race, rather than promoting close on-track competition. I'm not sure what he was expecting. This is the basic principle of modern bopping and success penalties. |

Super GT doesn't have massive swings, you need like 4-5 races worth of good finishes before you see cars really completely out of it. His issue is specifically increasing the handicaps by a third. That increase didn't put any of the privateers in contention at Fuji while making the gap between the two Toyotas insurmountable for the Silverstone winner so it was a complete parade, and meant that instead of perhaps a close battle between Rebellion and Toyota at Shanghai it was pretty much a slam dunk because it was 1.85s difference in handicap instead of 1.39s. (.56s x 125 laps would put them within 4s of each other instead of 67s apart as a dirty guesstimate)

Which makes it easier to get the success ballast right and avoid big swings.
The principle to get equal performance and close lap times/competition at a race is the same. If the cars start out with inherently more varied performance as in WEC compared to Super GT it is going to be harder. It’s not working well, as pointed out by Toyota. I’m not surprised that the changes are too dramatic. However having big variations race by race is not the aim. |

Brendon Hartley will drive for TMG into the LMP1 Hypercar era, as he was granted release by Porsche Motorsport to become a Toyota factory driver it appears.

Toyota Considering Another Record-Breaking Le Mans Run With TS050
3:10 lap possible as part of the TS050 HYBRID swansong? http://www.dailysportscar.com/2019/1...GSiwjckErjo0aw |

Wait I don't understand the message of the article. They mention breaking the Kobayashi pole record but at the same time there is talk of perhaps doing it whenever the track is open? "Unrestricted car" also refers to car being essentially illegal to whatever existing regulations are, as per what Porsche did with 919. And thus, very much meaningless PR.
Anyway even by doing nothing special they can easily beat the old Q record next year considering ACO's gonna erase all of the eot-succes-bop after Spa. Also the new Hyperbole-nonsense will mean less traffic on track = clear lap = speeeed |

If they're talking about a car like Porsche did, they haven't even decided on that yet, so I doubt that's what they are talking about during LM week(s) next year. The ACO won't let them do that with that car unless it's an unsanctioned event. Maybe they want to try both? Outright lap record and real lap record? |

I didn't mind it when Porsche did it. I liked that it showed the "what-if" and that the car wasn't too far away from the regular 919. What I didn't like was that they did that INSTEAD of racing the regular 919. Even just one car for European races and Le Mans in 2018 would have been nice. If Toyota do it, at least it won't be at the cost of the car racing because it'll be retired. Maybe they'll make their road hypercar do it? 'Ahem' (Valkyrie at the nurburgring)
