Alonso came in on second position today with a gap of +0.364 sec. Once again, F138 was driven close to 560 kms (120 laps). Both times, Rosberg on Mercedes and Alonso with his F138, achieved their best laptime in the morning on soft tires. There was no improvement on the super soft tires in the afternoon.
Comparing 2012 to 2013 it looks like the cars are about 2 sec. faster than 2012 and this is obviously refering to all teams of the top segment.
Below are the "pure figures" and there is a sheet of data to compare to be seen by visiting the "Picture Box".
