IT would be easier to list what hasn't changed on Falcon than what has, as the comprehensive midlife model BA facelift is more like an all-new model.

In short, the $500 million upgrade - double what Holden spent to develop the VY Commodore - has resulted in changes across the board, not just to the interior and front and rear-end styling.

Also new are the engines - including the Fairmont Ghia's optional new 5.4-litre overhead cam V8 - transmissions, suspension, brakes, steering, safety, seats, ventilation and audio systems.
