FIVE BIG QUESTIONS AHEAD OF THE SUPERCARS SEASON OPENER:
* Will Holden's new ZB Commodore change the game? The new generation Commodore will debut in Adelaide as the first hatchback to hit the Supercars grid. There are unknowns as to how the new body will behave and defending champion Jamie Whincup says Red Bull Racing will take two to three rounds to get on top of the car.
* Can Scott McLaughlin bounce back from his Newcastle horror show? The Ford ace claimed a record 16 pole positions last year but an error-riddled final round handed the championship to Jamie Whincup in dramatic circumstances.
