Lewis Hamilton suffered two spins as he got to grips with a treacherous Autodromo Hermanos Rodriguez, the newly crowned 2015 F1 champion describing the revised circuit as 'crazy slippery'.

The Mercedes driver looks somewhat out of sorts as he found the limit of the revamped venue, which is returning to the schedule after an absence of 23 years, proving 11th quickest in FP1 and fourth in FP2, four tenths down on pace setting team-mate Nico Rosberg.

Bemused by the slipperiness of the Mexico City circuit, which hasn't seen any track action for several years and only had its tarmac laid in recent weeks, Hamilton compared it to a go-kart track.

"It was interesting," he said. "It was very slippery out there and it's crazy because we are so high in altitude that there is worse grip than we had in Monza, which is quite low. We are just sliding around and it's more like a go-kart track in the slow areas."
