mark and lewis both use a lot of fuel per lap then say button or alonso......its just their driving style does that.....schuey did ok in the tests and has done a lot of laps in a gp2 car...so he will be in good shape first race me thinks......this year will be a rather tight one.....drivers challenging for the championship would be: Button, Hamilton, Alonso, Massa, Webber, Vetel, Schuey
