Formula1

QualifyingIn a very slight tweak to the familiar knockout qualifying format, the duration of Q1 has been increased from 15 to 20 minutes, while that of Q3 has been cut from 15 to 10. Q2 remains 15-minutes long. Furthermore, cars participating in Q3 will no longer get back the fuel used in that session - they must now start the race with whatever fuel was left in the car at the end of qualifying, thus eliminating the need for the infamous 'fuel-burning' phase at the start of Q3.Cockpit safetyOne of the slightly more visible differences to the cars this season will be an increase in the height of the cockpit padding - and hence the cockpit sides - on either side of the driver’s helmet, a change that has been implemented to further increase head protection in the event of an impact.BiofuelAs part of moves to make Formula One racing ever more environmentally friendly, the FIA has introduced a new rule governing fuel. From 2008, at least 5.75 percent of all fuel must contain biomatter and, as a result, all cars must be designed to be biofuel compliant.
