Which teams are using KERS this year?

both mclaren drivers ( Heikki Kovalinen and Lewis Hamilton) both ferrari drivers (Felipe Massa and Kimi Raikonnen) both renault drivers (Fernando Alonso and Nelson Piquet) and just one of BMWs drivers (Nick Heidfeild) because KERS weights alot and Kubica is already alot heavier than his team mate so the amount of weight will slow him down too much that the KERS won't be effective.

I've done a little search on Google and at the moment all I can come up with is that Renault will be using KERS ~ Renault are the first team to use it ~

Enjoy the race on Sunday ~ Fingers crossed for Jenson also I hope Lewis does better :-)

Both the Ferrari's, both the McLaren's, both the Renault's and Heidfelds BMW Just 7 cars right now

I expect some teams will change depending on the track - it's more useful on some than others.

Currently ferrari, mclaren, one bmw driver and renault

Not sure i would think you would need to look on each of the teams websites to know. but i would think latest by the end of the season all the teams will have it.

renault,mclaren,bmw,toyota,red bull(not sure)williams(not sure),...
