Welcome to the new Formula1 season and welcome to the first Grand Prix on the Bahrain Sakhir Circuit. Like every year there are a few new regulations the drivers and teams have to get to grips with. The most important is definitely that no refuelling is allowed anymore during the entire length of the race. Another obvious change is that the front tyres are about 2,5 cm narrower which will affect the cars set up an awful lot. Also the minimal weight of a Formula1 car is now 620 kilogram, 15kilo more than last year AT&T Williams driver Nico Hülkenberg and F1 expert Christian Danner explain the new regulations.
