Free Practice 1
Under the searing Sao Paulo sun, the Red Bull pair of Sebastian Vettel and Mark Webber led the standings in the opening session of the weekend.
Indeed the young German setting a fastest time 0.482 of-a-second ahead of his Australian counterpart.

McLaren arrived at Interlagos with various aerodynamic pieces – Lewis Hamilton with a new front wing; while Jenson Button utilised an old front, but a new rear wing.
The British team also brought an updated floor to Interlagos – all these additions would help Hamilton and Button register the 3rd and 4th best times respectively.

Mercedes spent the morning testing a 2011-spec rear diffuser. The German team remained some distance behind Red Bull and McLaren in laps times, with Nico Rosberg (6th) 1.1 seconds slower than Vettel and Michael Schumacher 1.3 seconds adrift (8th).
Ferrari arrived in Brazil with a new blown diffuser, with both red cars using the session to work on race set-up. The opening 90 minute stint concluded with Fernando Alonso shutting off his engine just prior to its failure. Thankfully for the Spaniard, it was on its final session and due to be removed regardless.

With only a few minutes remaining, Renault’s Vitaly Petrov suffered a minor rear wing failure, pitching his yellow and black machine into the barriers at turn 7. The young Russian was 15th best time in the session, while Renault team leader, Robert Kubica achieved the 5th best time – a clear one second faster – only adding to the pressure on Petrov’s shoulders.
Moments later, Sauber’s Kamui Kobayashi suffered a left rear puncture at the same spot, sending him slightly further down the turn 7 run-off area.  Kobayashi finished the morning in 11th, a mere 0.004 of-a-second slower than team mate Nick Heidfeld.  Toro Rosso’s Jaime Alguersuari had more of a polite spin on the entry of turn 1. The Spaniard kept his Ferrari engine running and made his way back to his pit stall.

Lotus’ Jarno Trulli was the faster of the Lotus pair and indeed the fastest of the “new teams”, albeit 3.2 seconds off the leaders in 19th.  Jerome D’Ambrosio again sat in for Lucas di Grassi at Virgin for the first practice session. There are growing rumours that D’Ambrosio will be occupying di Grassi’s seat for 2011 and sessions such as this are vital mileage for the young Belgian.
Christian Klien has replaced Sakon Yamamoto at Hispania Racing for the weekend and possibly Abu Dhabi. The former Red Bull runner clocked the 23rd fastest time and was a clear half-a-second ahead of Hispania regular, Bruno Senna. This will be the Brazilian’s first time to ever race at his home circuit, but it is highly unlikely that he will be garnering points.

Free Practice 2
The afternoon practice session saw the Red Bull’s continue their timesheet domination, headed once again by Sebastian Vettel. Again Mark Webber was next up, with the Ferrari’s of Fernando Alonso and Felipe Massa 3rd and 5th fastest respectively. The red duo squeezed Lewis Hamilton’s McLaren come the chequered flag.

As tyres began to fall off during the session, there were slight offs from Heikki Kovalainen (Lotus), Robert Kubica and Kamui Kobayashi and Massa – thankfully none of them suffered any damage. The session would only get worse for Massa. On his first run on the soft tyre later in the session, the Brazilian clattered the turn 3 kerbs heavily enough to shut down his gearbox, leaving the Ferrari man to sit out the the second half of the afternoon.
At the tail end of the session, an impatient Michael Schumacher launched a risky pass around the outside of a recovering Jaime Alguersuari on the approach of turn 1. The Spaniard had spun in the previous corner and the pair clattered eachother slightly, as the veteran shut the door hard on the Toro Rosso driver.

Lucas di Grassi found himself back in the driving seat at Virgin for the afternoon. The Brazilian driver registered the 21st quickest lap ahead of the Hispania pair and team mate Timo Glock.
