The Toyota GR010 has been slowed down by a double performance hit just before the race at Portimao on June 13.

The minimum weight that Toyota will need to respect has been increased by 26kg, going from 1040kg to 1066kg.

Compared to the first race in Spa, the new Toyota challenger will have 7bhp less, and the power across the rev range will be decreased as well. Plus, it will not have 964 megajoules of energy in total like in Spa, but only 962.

These changes to slow the Japanese team down under the BoP have been made ahead of the weekend during which the Glickenhaus team will participate as well.

The car developed by Glickenhaus will have 697bhp, the maximum power allowed. The minimum weight for them will be 1030kg since Glickenhaus has a two-wheel-drive LMH car.

The team will also be able to use more megajoule compared to Toyota, 965 in total.

Not only Toyota but some changes have been made also to the Alpine-Gibson A480. The ORECA P1’s minimum weight has been increased from 930kg to 952kg. Its engine will have 5 bhp, and 2 megajoules less at Portimao.

These changes made to slow the cars down have been made after a debate started by Toyota at Spa. The Japanese manufacturer stated that the gap between LMP1 and LMP2 was too small.

Toyota complained that the modifications made to the LMP2 class after last season were not enough and that the performance between the two categories is too similar.

Pascal Vasselon said that the two categories need to be in “different ballparks”. Moreover, Vasselon added that the entry of the Glickenhaus team will increase the problem even more since the performance of the Hypercars will need to be decreased.

However, the ACO said that the performance of the P2 cars will not be slowed down even more.

I am an Italian guy. I love Motorsport because of the emotions that it gives me and I grew up watching races. That's what I love!
