Button started race 20th on the grid following 70 place grid-penalties for changing engine unit, the Brit’s McLaren-Honda machine lacked too much strait-line speed to make progress during the race, with only the two Manor cars finishing behind the British driver.
“Painful, I think, is the word. Button said, when asked to sum up his Mexican Grand Prix.
“I was on the harder tyre at the start but still it was just waving goodbye to everyone in front really. The straight-line speed that [other cars] have is just phenomenal.
“We’re still doing 345 [km/h] on the straight but they’re 20 km/h quicker than us so when they have DRS and they have full deployment they’re pulling 45 km/h quicker than us.
“It’s a massive difference in speed and I couldn’t hold people behind me even if I was in front of them – not that I was very often, unless they were pitting or lapping me.”
“We’ve lost more power here than most with the altitude for some reason,” he said.
“I don’t know why; normally you’d think it would bring everyone closer together but it really hurt us here.”
