Massa fastest on day one at Jerez

So, the first day is complete at Jerez and  what have we learned?

Not much really, is the answer.

Massa's lap today and Ferrari's all round pace from last week's test in Valencia would seem to indicate they will be strong while in their respective McLaren and Red Bull cars, Lewis Hamilton and Mark Webber would appear to have untapped potential which could see them good come Bahrain next month.

Nick Heidfeld has now been given the clearest indication yet by Renault boss Eric Boullier that the drive is his to loose over the next few days as the team publicly admit they are seeking experience over youth.

Williams endured a torrid day as they encountered numerous problems with their adjustable rear wing system and Nico Rosberg looked frustrated as his Mercedes again failed to set any meaningful lap times in what was largely a frustrating day for the German marque.

Tomorrow brings with it Jenson Button in the McLaren and Michael Schumacher in the Mercedes in what look set to be the only driver alterations.

Roll on day two...
