A KEY component of the BA Falcon upgrade is the new Control Blade independent rear suspension, which has been adopted across the range.

On paper, the move finally sees the Blue Oval's pride and joy on a level pegging with Commodore, which has had standard IRS since the introduction of VT in 1997.

Control Blade refers to the suspension system's dominant feature - a longitudinal trailing arm with a large plush bush at one end.

Its key function is to improve ride comfort and reduce road noise transmission, while allowing the lateral links to define toe and camber.

The arrangement effectively isolates the handling components of the suspension from the road noise and impact harshness components.

The Control Blade IRS is lighter than the previous double wishbone set-up featured in the XR6 VCT, XR8 and high-series variants, but heavier than the live axle system previously employed in the lower level cars - which explains the greater weight increase experienced by the XT, Futura and XR6 against the other variants.
