Technical problem for Vettel
The final test session of 2007 got underway today at the Jerez de la Frontera circuit. Unlike most of the year's tests, this one is due to last for four days. As in Barcelona last month, German Seb was driving the car with 2008 electronics, while French Seb had the 2007 package with the relevant driver aids switched off.
Vettel's programme therefore focussed on development of gearbox and engine control systems, but his day was cut short due to a technical problem. However, prior to that, he did manage to complete a brake system evaluation.
Bourdais had a trouble free day, completing the second highest number of laps. He worked on a front flap comparison while also carrying out an evaluation of front suspension solutions.
Both drivers continue testing tomorrow.
