The recent announcement from the Williams F1 promoting Valtteri Bottas as one of the teams 2013 drivers has seen the team defend their decision that saw Valtteri take over from Bruno Senna during Friday practice sessions at many of the 2012 Grand Prix. But Bruno would claim that the loss of the track time was hindering his driving.

But in the light of the switch to Valtteri for the 2013 season it seems to vindicate their decision to give him track time in 2012. But if Bruno had more track time would have he performed better.

In discussions with Autosport.com Williams Chief Operations Engineer Mark Gillan put forward the view that having Valtteri run on the Friday's was certainly beneficial to the team.

As for whether Bruno's poor form during the season may have being contributed to by his loss of track time on Friday. Gillan replied: "It's a good question. It's one that we will look at in depth.

"It's a balancing act. It's something that we all knew at the beginning of the season and we did our best to mitigate Bruno missing FP1 and did our best to learn from Valtteri.

"Each driver has different feedback. Bruno is different to Pastor, Valtteri is very different to Bruno and Pastor, and we've learned from that a lot.

"Valtteri benefited tremendously from it. We have got a lot from the third driver as well."

"With Valtteri being in the simulator a lot, it's important that he's had track time so that our virtual simulation package can be pushed forward," Gillan added.

In further news regarding Valtteri he is backed by Antti Aarnio-Wihuri, whose company Wirhuri is a global industry and trade conglomerate.

Aarnio-Wihuri is quoted sa saying “I have a personal acquaintance with Frank Williams, which played a role.

“On next year’s car we will have big ads. We are talking about substantial sums, but not tens of millions, as has been mentioned for some of the other [F1] drivers.

“We hope to get back the money we have invested through the advertising.”
