Having qualified last, Yamaha rider Quartararo could do no better than 21st in the 10-lap sprint on Saturday at Silverstone.
For much of the contest, all of the six riders on Japanese bikes occupied the bottom six places in the field, with only Franco Morbidelli marginally sparing blushes by taking the chequered flag in 15th.
It continued the dearth in results the Japanese manufacturers have experienced for much of 2023.
Asked by Autosport if he felt the riders at Yamaha and Honda are being embarrassed by the Japanese manufacturers right now, Quartararo replied: “Well, of course.
“I mean, if you check, now it’s more the European bikes than the Japanese bikes, but there is not one [Japanese manufacturer rider] on top and the others bottom.
“All of us are down, so for sure we are doing something wrong.
“But especially from my side starting that far down, we will have to do something totally different tomorrow.
“We have nothing to lose and my priority now is to try to improve, to be more in front and make a step forward in the coming races, where normally in the second half of the season is where we drop down.”
