Lewis Hamilton says the lack of grip during Friday practice for the Mexican Grand Prix made it feel "like a go-kart track".
The Autodromo Hermanos Rodriguez is being used for a grand prix weekend for the first time since 1992 and grip levels were low on Friday. With the circuit at an altitude of 2219 metres, the air pressure means the cars are delivering less downforce from their aerodynamics, which is adding to the lack of grip.
Asked how he would sum up his day on Friday, Hamilton replied: "Interesting.
"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."
Hamilton has so far won 10 races this season with three remaining, meaning it is possible for him to match the record of 13 in a season currently jointly held by Sebastian Vettel and Michael Schumacher. However, the triple world champion says such a record is not his motivation.
"Not at all. [The motivation is] same as usual, I’ll just try to do the best I can. I don’t have any desire to [match] that, I don’t really have a care about what they’ve done because it’s not really the same."
