ONE thing that has not changed with the BA Falcon is its use of the traditional large Aussie sedan layout. Like Commodore, Falcon remains a rear-wheel drive four-door with a longitudinally mounted six-cylinder engine residing up front.

In Falcon's case it's a cast iron block/alloy head inline six with 4.0-litre capacity that features twin overhead camshafts and four valves per cylinder - versus Commodore's cast iron, two-valve pushrod V6. All BA Falcon sedans now employ a two-piece driveshaft.
