With just under two weeks before the season opening Australian GP, only one team – Renault – has confirmed that it will run its Kenetic Energy Recovery System (KERS). This will give Alonso and Piquet about 80 extra horsepower for a few seconds each lap, but comes with a weight and balance penalty.
So far the teams view of KERS in Australia is:

McLaren – undecided, possibly yes
Ferrari – undecided, probably no
BMW – undecided, possibly yes
Renault – Yes
Toyota – No
Williams – No
Red Bull – No
Toro Rosso – No
Force India – No
Brawn – No
