In terms of the power-unit the Mercedes and Ferrari powered teams seem to have the advantage now. The Renault powered cars had many problems. Because of that for example Red Bull did manage only 21 laps in the four days of testing in Jerez, while Ferrari and Mercedes did 80-100 laps per day.
But I have no idea, which aerodynamic package will do the best job. I really think that Lotus' nose could be a brilliant piece of designing. They are the only team, who had this idea to cope with the new regulations and I think it may work. What worries me is that they revealed it, although they knew they did not go to the testing at Jerez. Why would they show their solution and blow their whistle so early and unnecessarily? Maybe to bind some work-force of the other teams, which maybe would try out, if this solution works...? But I hope this is not just a bluff and gives them an advantage. But I also hope that the Mercedes powered Force India team has a good car and my favourite driver Nico Hülkenberg can score well in the 2014 season.
We will see...
