Cold weather conditions could throw a spanner in the works for Formula One drivers in Shanghai this weekend.
With temperatures under 10 degrees centigrade, teams can expect major issues warming up their tyres.
Although forecasters reckon it will start warming up by the weekend it will make qualifying for the Chinese Grand Prix tricky.
Red bull racer Sebastian Vettel said: “In these conditions, similar to what we saw last year at the Nurburgring, you might struggle to warm up the tyres.
“Traditionally we don’t struggle with that as much as the others, but if it’s as cold as that, you might never get into the working window and you could just grain your tyres.
“On the other hand, this track is quite smooth, and usually that helps the warm-up.”
Sauber’s Pedro de la Rosa agreed that the low temperatures could cast a cloud over the practice and qualifying sessions and warned that it may take several laps to get tyres up to a competitive working temperature.
The practice and qualifying days are currently expected to be dry but cold, with a possibility of rain for the race – by which time it should at least have warmed up slightly.
