2013 Malaysian Grand Prix Friday practice one

0 min: He is followed onto the track by Toro Rosso team-mate Jean-Eric Vergne.

0 min: Pic heads out in his Caterham to join the early runners.

0 min: Daniel Ricciardo is the first driver out onto the circuit.

Button is also ready for action as McLaren continues its efforts to understand the troublesome MP4-28.

Melbourne winner Raikkonen is all set for an early installation lap in his Lotus.

We can expect asphalt temperature to climb through the mid-forties and perhaps into the low-fifties later this afternoon, triple the numbers from Australia one week ago.

Track temperature is 33 degrees Celsius, with a few minutes to go until the start of the session.

Tyres

It was all about the tyres last weekend in Melbourne and there's every indication that rubber will be the big talking point here as well, with Pirelli supplying the white-marked medium and orange-ringed hard versions of its all-new range.

Super-soft rubber proved fragile at the first round, so teams will be hoping that the move to the hardest possible allocation will lead to greater durability in the heat of Malaysia.

As ever, the limited allocation of tyres for practice will see outfits largely running on a single set of the hard compound in this first session.

It's all-change on the weather front with the cool and showery conditions being replaced by Malaysia's fierce heat and humidity.

The afternoon storm will no doubt come later, but for now we are looking at a dry and hot first session in the morning sunshine, with air temperature climbing up towards today's maximum of 33 degrees Celsius.

Here's how the championship looks after the opening round in Australia: Drivers: Constructors: 1. Raikkonen 25 1. Ferrari 30 2. Alonso 18 2. Lotus-Renault 26 3. Vettel 15 3. Red Bull-Renault 23 4. Massa 12 4. Mercedes 10 5. Hamilton 10 5. Force India-Mercedes 10 6. Webber 8 6. McLaren-Mercedes 2 7. Sutil 6 8. Di Resta 4

Raikkonen

Good morning everyone and welcome to AUTOSPORT Live as the Formula 1 world championship rolls on to round two - the Malaysian Grand Prix weekend at the hot and sticky Sepang International Circuit.

Kimi Raikkonen told Lotus that the E21 was a good car, as it proved five days ago with a wonderful tyre-conserving victory in Melbourne to open his 2013 account with 25 points.

Ferrari will be buoyed by the initial pace of its new car, while there must be a certain amount of head-scratching going on at Red Bull, having started from the front row of the grid at Albert Park, but only leaving with a third and sixth place finish - not what the Milton Keynes-based outfit is used to.

The campaign trails steams into Sepang for the next installment and, as always, the opening practice session will be about making sure the cars run properly after being stripped down and rebuilt, before the drivers and race engineers can move into some baseline set-up work.
