The F6 engine is based on XR6T motor, a turbocharged intercooled DOHC 4.0L Inline Six with VCT, but includes: a modified FPV airbox (with Dual Ram Air intakes), higher strength conrods, larger air-to-air intercooler, high flow exhaust system, higher capacity fuel pump, and a Garrett GT3582r (same as the BA/BF XR6T) turbocharger with an internal waste gate (up from the GT3576r on the FG XR6T) running 0.64 bar of boost on the BA/BF models and 0.91 on the FG.

FPV also developed the Force 6 as a luxury orientated version of the F6, and a Territory based F6-X.

The car had a more low-key look than the V8-powered FPV's with a lower rear wing, no body stripes.

The F6 also scored a more aggressive bodykit to further differentiate it from other vehicles in the FPV range, as well as 19-inch (480 mm) "Dark Argent" Alloys.

This model was equipped with several upgrades including stiffer suspension and 19'x8" alloy wheels which sought to improve the car's handling.

Colours that the R Spec Typhoon was released in included winter white, lightning strike, vixen, neo, ego, bionic and silhouette.

The R spec model was also available as a special order in custom option colour choice, At least two are known to be in Fords "Conquer Blue Metallic" with the dark ardent inserts.

Key changes included new front suspension, a new steering rack, all-new exterior and interior design and a revised 6-speed manual transmission with launch control.

In 2005, the BAII F6 Typhoon was disqualified from Motor magazine's annual Performance Car of the Year competition due to a series of clutch failures.

[citation needed] The F6 Typhoon returned to win Motor magazine's Australian Performance Car of the Year award in 2006.
