McLaren continued to lead the way in testing in Portugal after Pedro de la Rosa set the fastest time on day two of running at the new Portimao circuit on the Algarve.
Spaniard Pedro de la Rosa took over at the wheel from fellow test driver Gary Paffett and spent the entire day running in the MP4-23K KERS car.
Although he struggled to find grip early in the day, de la Rosa was soon on the pace and posted the quickest time of 1min 30,080secs as he also complete aero testing alongside his KERS programme.
Ferrari meanwhile had two drivers out on track for the second day of the test, with Luca Badoer and Marc Gene both on track.
Badoer was the quicker of the pair with a lap of 1min 31.320secs while Gene was almost two seconds further back in third.
