there's no driver changes on the top 4 teams from last year.
the biggest technical change is pirelli supplies tires instead of bridgestone and were asked to increase wear to force more pit stops. you won't see 1 or 2 pit strategies. it'll now be 3 or 4.
the double diffuser's from last year are banned. kers is back. the back wing can now be opened to reduce downforce on straights. some of the teams are venting exhaust to the front of the car which is supposed to help aerodynamics. watch the first 15 minutes of any race early in the season and you'll know as much as anyone.
