First day of the Winter tests
Jerez saw the first hunt on Pirelli slicks this season. Usually the first days will not leave comparable results as every team and driver are testing the new cars, tires and components.

However, we can compare results from Day 1 2012 to Day 1 2013. Jenson Button was fastest today with 1:18.861 what used to be 1 sec. faster than the best time on Day 1 in 2012 (by Kimi Raikkönen).

Massa does the Jerez test this year as well as he did in 2012. In 2012 his best lap on Day 1 was 1:22.815. Today, he achieved 1:20.536, means he was 2.2 sec. faster. The gap between the fastest and Massa is much smaller this year: +1.675 compared to +3.145 sec. in 2012.

The record lap in Jerez is still held by Michael Schumacher on his F2004 with 1:15.614.
