Major changes call for interesting races this season

Three major changes have taken place this season that are changing the game for all the drivers. This year Pirelli is the tire provider for the teams. They're different from the tires previously provided by Bridgestone. The new tires wear a lot faster than the previous so drivers need to make more pit stops and create effective pit and tire strategies. The second change is the KERS system that pretty much gives you a boost. The last change is the DRS which is an adjustable rear wing that helps when passing another driver. If all of this sounds foreign to you, Michael Schumacher explains each with a little more detail in the video above.
