New rules set to take rivalries of track

Ferrari's Felipe Massa said the switch from aerodynamic grip to tire grip will be the hardest of all the new rules for drivers to adjust to.

"The biggest change is the aerodynamic. It makes the car completely different in terms of driving," Massa said. "The KERS is something you need to understand, you just press the button and get some power, and slicks just give more grip.

"So for the driver, when you put grip on the car, it is always easier. But when you take it away, the grip is a little bit more difficult to learn and to get used to."
