Former Formula 1 driver Brundle echoed the Mercedes team's feelings, labelling the race in Sao Paulo as nothing short of disastrous.
"It wasn't a classic race by any means," Brundle said during his Sky Sports analysis. "Both Mercedes' of Hamilton and Russell continuing their poor race pace of Saturday, but for three times as long and it was painful to watch.
"They eventually retired Russell, and Hamilton grabbed a few points in eighth place."
Following the race the entire Mercedes team shared a similar perspective, expressing their collective disbelief at the weekend's performance.
Russell attempted to explain his early race retirement but ultimately described the car as just "slow".
"But the pace just hasn’t been there," Russell said. "We thought yesterday may have been a one off but clearly it wasn't. The car was just slow this weekend. The tyres were just sliding around, and I think that what we were doing was the maximum.
"Something doesn't quite add up, we don't just suddenly lose a second's worth of performance and go from a podium fighting car, to just fighting for points."
Hamilton had a more direct response to the weekend's performance, expressing his desire to never drive this Mercedes again after the final two races this year.
"We're pretty slow through the straights and pretty slow through the corners," Hamilton said. "One to forget, but hopefully there are lots of learnings from today.
"One thing the car is really unpredictable in the sense of one weekend it feels good, one session it feels good. I'm sure we'll go and look at things and find out we should have done these differently.
"But with the one session, it's difficult. Two more races with this thing and hopefully no more driving it!"
