This thread is only for posting F1 Team member quotes so we can draw conclusions regarding the advantages/disadvantages of the KERS system.
Recent F1 Leading Team Member quotes:
Ferrari - Domenicali
"Something we must consider is the weight distribution of the car and how it affects the tyres, particularly with KERS onboard - we need to discovery how to solve this problem, but still be able to use KERS."
BMW - Theissen
"Even though we managed to build a reasonably light KERS device we are still not able to get the perfect balance in Robert's car; he won't use it Melbourne although we hope we are able to fit it to his car later this season."
Renault - Alonso
"... the device is quite heavy. The ballast we had last year, you were able to move it to set up the car."
Toyota - Pascal Vasselon
“At the moment our estimation is that KERS will be detrimental on almost all circuits, because of the weight and the difficulty to manage braking.”
