Lewis Hamilton made it two from two on Friday in Brazil as he again beat Sebastian Vettel, this time by 0.274s using the medium Pirelli tyres.
With the track temperature a sweltering 49'C, Practice Two got underway at the Interlagos circuit. In fact it was so hot out on track that after just 10 minutes of running Nico Hulkenberg reported that his rear tyres were "cooking."
Felipe Massa set the early pace as the drivers put in the laps on the harder option Pirelli tyres. The Brazilian was down to a 1:15.473, 0.121s up on Mark Webber and a further 0.005s quicker than Jenson Button.
But it was all-change as Fernando Alonso hit the front only to lose out to Sebastian Vettel who was right behind him on track. The German had the benchmark down to a 1:15.226. Button slotted in between the two title rivals, which was how the timesheets stood after the first 30 minutes.
After a brief break the Championship rivals returned to the action with Alonso up through the second sector before a mistake cost him. Alonso's second lap puts him top by 0.076s.
Romain Grosjean was the first driver to use the medium tyres and hit the front with a 1:14.994. He soon lost out to Nico Rosberg then Felipe Massa and then Lewis Hamilton. The McLaren driver lowered the benchmark to a 1:14.026 and was leading at the 60 minute mark.
Shortly after Vettel, who had dropped to 11th while in the pits, shot up the timesheets, putting in a fastst time in the first sector before losing ground in the second and third. He finished second, 0.274s down.
Meanwhile, Kamui Kobayashi, who this morning was dropped by Sauber for next season, had an airborne moment over the kerbs which he would have definitely felt. Charles Pic, in his last weekend as a Marussia driver, had an early shower as he parked his car with 20 minutes remaining.
Those final 20 minutes saw the drivers switch to heavier fuel loads, which meant they were lapping about 5.5s slower than their previous best times. Hamilton was doing some consistent 1:19.5s during the long runs while Alonso was about 1:19.9s and Vettel was jumping around by as much as a full second.
The session ended with Hamilton quickest ahead of Vettel and Webber.
