FGX Falcon

2015-2018 · 27/41 specifications catalogued

The Ford FGX Falcon (styled FG X) was the facelifted Falcon that carried Ford through the second half of the Car of the Future / Gen I era, raced from 2015 to 2018. It replaced the FG Falcon (COTF) and was Ford's last Falcon in the championship before the Mustang arrived for 2019.

A facelift on the control chassis

For 2015 Ford re-skinned the ageing FG race car with the road FG X facelift's nose and tail. Underneath, the car was unchanged in principle: the same Car of the Future control chassis introduced in 2013, with its rear-mounted transaxle (Albins, later XTrac sequential), control rear differential and common safety-cell components. The FGX was a bodywork update rather than a new car — the control chassis and driveline carried straight over from the FG (COTF).

Body & aero

The race car wore the four-door FG X silhouette. As with every Gen I car, the bodies were aero-matched to a common downforce and drag target; the front splitter, undertray and rear wing form a controlled package set by the technical rules and are not published here as per-car figures.

The FG X skin was more than cosmetic where it mattered. Its front bumper was reprofiled — the FG's smooth lower "cheeks" giving way to a stepped form — and the front undertray extended, the FG's 75 mm cut-out filled and a further 45 mm added. At the rear the wing was made wider, mounted further back off the boot and lower, its maximum angle raised to 18° and the gurney flap enlarged from 9.5 to 13 mm — all aimed at curing the FG's chronic rear-downforce deficit. The revisions came out of a Prodrive/Ford CFD study begun early in 2014 and were signed off under the category's straight-line VCAT aero test at East Sale in January 2015.

Engine & driveline

The FGX kept Ford's established 5.0-litre racing V8 — a naturally aspirated 90-degree unit with an SVO iron block and aluminium heads, the same purpose-built race-engine family Ford had run since the Blueprint era, rather than a production-derived engine. It ran on E85 control fuel through the rear transaxle and control differential, on the single-make Dunlop control tyre.

Teams & run-out

Prodrive Racing Australia (the former Ford Performance Racing) and DJR Team Penske led the Ford effort through the FGX years. It was the last Falcon to race in the category: Ford's factory programme returned with the Mustang for 2019, ending decades of Falcon touring cars.
