Circuit de Catalunya, Barcelona 4.655 kms
Best time: 1:22.158
Scuderia Toro Rosso's new car, the STR4, has completed its first day of testing, producing a positive result, having completed twenty laps more than a Grand Prix distance at the Spanish circuit.
"It's much too early to talk about performance," said Bourdais at the end of the day. "However, the car seems to work well and we've already learned a lot today. If we can carry on like this for the next few days, it will be a good starting point for the season."
Bourdais continues to drive tomorrow, before handing over to Sebastien Buemi for the final two days of the session.
