The new injection set up is accompanied by new light weight pistons and rings, a higher compression ratio of 12.0:1 and other modifications that improve power and economy.

These figures virtually match the petrol version for power and torque when running on 95 octane fuel.

[7] The Falcon will be the first rear drive application using the Ecoboost engine, however, not capable of matching 380 N⋅m (280 lb⋅ft) of torque available at as low as 1500 rpm on the 4.0L petrol version thanks to the 4.0L petrol version's Ti-VCT or Twin Independent Variable Cam Timing, a new intake manifold, cam profiles and combustion chamber changes over the Barra182.

[9] From 1 September 2008, all XT models were specified with alloy wheels as standard equipment, previously an extra-cost option.

[10] The base model in the XR range, which features the same 4.0L I6 engine found in the XT, G6, and G6E, coming with a different ECU with a unique sport-tune.

It comes with a 5 or 6-Speed automatic transmission, or a 6-speed manual transmission, 17 x 8-inch 5-spoke alloy wheels; optional 18" and 19"-inch wheels are available, Sports Control Blade Independent Rear Suspension (IRS), Sports body kit with side skirts and rear bumper, rear spoiler, front fog lamps, leather-wrapped steering wheel with mounted audio controls, Bluetooth as an extra, alloy pedal covers and cloth sports seats.

The Turbo model of the XR6 comes with all of the features of the standard XR6 plus 18 x 8-inch five-spoke alloy wheels, limited slip differential, and upgraded front brakes (322mm rotors instead of the standard 298mm) without an option for 328mm x 26mm ventilated rear discs as found on BF Mk1 XR6T and XR8 models, losing on the braking capacity overall with 303mmx16mm solid rear discs, the same hardware found on the original BA XT from 2002.

The I6 engine also has the ability to provide the driver with an "over-boost" feature which engages temporarily when the throttle is fully depressed at speed & correct atmospheric measures are met.

Once correct conditions have been met, the engine will provide an increase in boost pressure of up to 12psi from a standard maximum of 10psi; which allows for power around the 330 kW (443 hp) mark.

Both the XR6 and XR6 Turbo can be optioned with the "XR Luxury Pack", which adds sports leather seats and black carbon look trim inserts, dual zone climate control, 19x8 inch alloy wheels, and premium sound.

The "Tech pack" is also available and adds Bluetooth and iPod integration; both option packs add almost all the features from the G6E (minus reversing camera, curtain and side thorax airbags, an 8-way power adjustable driver's seat and memory mirrors, overhead sunglasses holder and mirror indicators) The XR8 had the same features that are found in the XR6 Turbo.

The Falcon XR8 was discontinued in June 2010 as a result of its 5.4-litre engine not complying with the Euro IV emissions standard adopted by Australia at that time.

Although initially expected to be reintroduced with the 5.0-litre "Coyote" engine used in the Ford Mustang GT during 2011,[11] the model was re-introduced in 2014 with the FG-X series Falcon, featuring the 5.0 litre supercharged Miami motor.

It includes all of the features of the G6, plus a ZF six-speed automatic transmission, dual zone automatic climate control, a premium audio system, leather seats, Bluetooth mobile phone integration, reversing camera, curtain and side thorax airbags, an 8-way power adjustable driver's seat, 17 x 8-inch 10-spoke alloy wheels, front scuff plates and an overhead sunglass console.

It was also announced that the LPG E-Gas models, like the petrol-powered versions of the FG sedan range, had been awarded the full five-stars in the ANCAP crash safety test.

ESC was also made standard on the E-Gas BF III Falcon wagons still in production (previously unavailable).

ESC fitment was extended to the utility body styles from May 2009, excluding the base XL and R6 Ute, where it was optional.

The MkII has a revised front fascia similar to that of the SZ Ford Territory, this includes a smaller upper grille and a larger octagonal lower grille, along with revised headlight and fog light assemblies, G6E and G6E turbo models come standard with LED running lights.

All new specification levels (except XT and XL) get the new ICC (Interior Command Centre), the unit is an 8" touch screen with 2D and 3D maps, SUNA traffic updates overspeed and speed camera warnings, street house number display and is fully integrated.

Its distinguishing exterior features included unique "GS" decals and dark argent wheels.

In October 2010, FPV introduced a supercharged all-alloy DOHC 4 valves per cylinder Coyote "Miami" 5.0 L; 302.1 cu in (4,951 cc) V8 engine to replace the older 5.4 L Boss unit.
