02:54 The significantly cooler conditions today might be enough to cause the teams a headache, with the change in temperature potentially altering the conclusions on tyre performance captured during yesterday's sessions.
Pirelli's data points to significantly reduced degradation over the extremes of Malaysia, with a greater difference in durability between the two available compounds opening up strategy options for the teams.
This final hour will allow for further data to be collected before the final decisions are made on strategy for qualifying and the race.
Pirelli: One-stop Chinese GP possible
02:52 In a complete change to yesterday's muggy and somewhat smoggy conditions, it is much cooler today, but still it remains rather cloudy with a north-easterly breeze bringing temperatures down.
The nearest rain is south of the city and some 50 to 60 miles away, as the low we spoke about drives showers to the south-east and away from the circuit.
The north-easterly airflow will keep temperatures down today, with a maximum of just 16 or 17 degrees Celsius expected during qualifying.
02:50 Good morning everyone and welcome to AUTOSPORT Live for continuing coverage of the third round in the 2011 FIA Formula 1 world championship - the Chinese Grand Prix from the Shanghai International Circuit.
Red Bull got down to business yesterday with solid pace in both qualifying and race trim, yet despite the obvious speed from the RB7, question marks still hang in the air over the team's KERS and its reliability. However, the same could be said for McLaren: Jenson Button crackled over the radio during practice also with KERS concerns, while Lewis Hamilton had tyre degradation on his mind.
The chasing pack is led by Ferrari, but rather than looking forward to battling with the top two teams, Alonso and Massa will likely have to fend off strong attack this weekend from Renault and Mercedes - that is, providing Nick Heidfeld can keep his R31 on the island.
We're set up for a good day's action and it begins with final practice in around 10 minutes'
A pobjedit može ko hoće.. Može i Schumi hehe 
, tolko od mene o toj temi
Renault... svaku utrku dosad šalju u zadnji čas, valjda da uštede na gumama. Sad im se obilo o glavu. A Kinezi preležerno miču bolid. Dok čekaju da dođe traktor, pa dok to prikopče, pa malo gledaju bolid 
. Da je bio takav ritam uklanjanja u utrci, imali bismo safety car desetak krugova.
