Toyota Given Weight Increase, Loses Stint Length Advantage

Toyota TS050 Hybrids face 26 kg weight increase, equalized stint length to non-hybrids…

The pair of Toyota TS050 Hybrids have been slowed and have lost its stint length advantage ahead of next weekend’s Six Hours of Fuji, in an unprecedented Equivalence of Technology adjustment handed down by the FIA.

Announced in the release of the Fuji EoT on Friday, the LMP1 hybrid will face a 26 kg weight increase, bringing the car up to a minimum weight of 904 kg for the Japanese round.

It compares to the non-hybrids that remain at 818 kg (normally aspirated) and 833 kg (turbocharged).

Additionally, the Toyotas lose its two-lap per stint advantage over the non-hybrids, with the two platforms now equalized for the first time this season.

It has resulted in an increase allocation of petrol energy and petrol per stint for the non-hybrids, with adjustments also made to the size of the refueling restrictors.

According to the FIA, the change was only made possible with “thanks to the agreement of the LMP1 H competitor” as the technical and sporting regulations prohibit any adjustments to the Toyota for the 2018-19 ‘Super Season’.

Additionally, the regs outlined that LMP1 hybrids would have a one-lap stint length advantage at Le Mans and two laps at all other WEC events.

The changes come amid dominant performances in the opening races of the season from Toyota, although the Japanese manufacturer lost its 1-2 finish in August’s Six Hours of Silverstone due to a technical infraction.

    A drop in the ocean. I still expect the Toyotas to dominate their home race.

    After all, THEY agreed to these changes…

      26kg is by no means a drop in the ocean. It will cost them 1.5 seconds per lap, increase tyre wear, and affect fuel mileage (however slight). Privateers can also change aero packages,. DrangonSpeed have recently been testing updates from Dallara/SMP.

      Toyota’s advantage has always been under race conditions. That won’t change but the privateers should be closer on a clear lap.

    I don’t like it, this is starting to become more like BoP than EoT. And yes, there is an actual difference between the two which now slowly seems to be eroding.

      It is effectively BoP. But these cars are very different configurations and extremely difficult to balance. We have a season and a half to make the best of it.

      It’s also the reason why the 20/21 GTP regs will dictate everyone uses the same hybrid configuration. No more balancing completely different technologies.

      It is more important to create equal outcomes with competitors having different rules in the LMP class than to have equal rules with unequal outcomes in the LMP class.

    Would it be way too cynical to suggest this is more than coincidence, happening for Fuji which is Toyota-owned?

    The fact that the FIA makes such a strong point about it happening only because Toyota agreed to the changes would seem to indicate they didn’t want to suffer the embarrassment of another runaway victory in their home race.

    I don’t buy the argument that it has taken this long to ‘balance’ the performance of the two LMP1 classes, given the level of monitoring carried out pre-delivery and subsequently, coupled with the stated intention of an overall performance gap between hybrid and non-hybrid cars.

    Rather, it just smacks of arrogance by the ACO/FIA that they wouldn’t face up to what was blatantly obvious; the LMP1H concept was unsustainable and in continuing to adhere to it they have crippled the whole LMP1 class by not addressing the performance gulf until now.

      BoP is far from simple.

      And the BoP have taken so incredibly much performance from the Toyotas its almost a disgrace to their engineers (or a accolade call it as you want). Its simply because the non-hybrids are still very new cars compared to the hybrids and arent´t up to 100%. Thats why they aren´t closer. I know these are the fastest P-cars without hybrid ever, but they keep breaking down and not running up to full potential.
      What now happened is more a success-based weight increase somewhat like in SuperGT.

    The ACO & Toyota are slowly killing the LMP1 class,which is what manufacturers always do if you give them any power.ITC/DTM is a good example.Say what you like about Stephane Ratel but he sets the rules & invites people to compete.
    Thanks to this stupidity we have a crap top class until 2021/22.

    Dump the expensive hybrid stuff,make it a simple LMP1/DPI style car & only let manufacturers compete if they also sell cars to privateers in the second year.It is ridiculous that we could easily have 20 privateers competing in the top class racing affordable LMP1s lapping at 3.20 around Le Mans.

      SRO racing is s***.

      We wouldn’t have 20 LMP1 cars without Toyota.

      We need manufacturers as much for activation and promotion as putting a couple of cars on the grid.

      Manufacturers want a marketing/technology angle like hybrid. Hence GTP will use hybrid. As will gen 2 DPI.

      well who doesn´t? But today it would lead to a definite k.o. in very short time. The costs would be extreme
