The Caterham F1 team has released their second unique video that allows the fans to see beyond the normal on-track videos. This one was after the first preseason test days in Jerez. They are now preparing for the second test days in Barcelona, Spain. While they still show their sense of humor, they are far more serious on the development they are undergoing in their preparation for the first Grand Prix of the new season.

"It's obviously far too early to make any judgements on the performance levels we can expect from the 2013 package," said Giedo van der Garde after his first time in the new CT03 in Jerez.

After the final day at Jerez, Charles Pic said, "One key part of this test was to work on getting the most out of KERS and we've definitely made good progress on that."

Included in this "unchained" video is a review of the first test at Jerez and a factory visit from some major partners.
