was the highest non-performance specification model in the range and sedan only. It had additional features that included unique wheels and even more wood grain-look dash inserts. Fairmont & Fairmont Ghia models were not badged as Falcons. In terms of safety equipment, the Futura, XR and Fairmont models all had ABS brakes in addition to a driver's airbag, which was the only main safety feature on the Falcon S and Forté. The brakes featured 287x24 mm vented front discs and 287x10.5 mm solid rear discs. External model differentiation was achieved via the use of different grilles and bonnets (low bonnet and vertical "salad slicer" grille on Forté, horizontal single bar on Futura, integrated quad-lamp bumper bar and grille on the XR sports range; high bonnet and large grille on Fairmont range) and more basic fittings such as different alloy wheel design, rear light clusters (clear turn signals on Fairmont), body colour-coordination and chrome fittings. The wagons featured a new rear-end relative to the previous generation Falcons. Inside, the Fairmont and XR model featured full instrumentation (oil and battery meters) and the Fairmont twins also adopted a different dashboard. As opposed to the standard Falcon featuring a large oval pod incorporating air conditioning and stereo, the luxury twin featured a 2-level shared with the long-wheelbase AU Fairlane/LTD, with a separate upper level featuring a woodgrain-like trim across to the passenger side that incorporated an analogue clock, trip computer and climate control. Only the Falcon XR6 VCT and Fairmont Ghia featured "Intech" engines produced by Tickford Vehicle Engineering with variable valve timing. The VCT was developed by Tickford in conjunction with Unisia Jecs who also supplied Jaguar for its V8 engines. IRS was fitted as standard on the Falcon XR6 VCT, XR8 and Fairmont Ghia, and optional on most other sedan models; the XR models being the only ones that could also be fitted with a limited slip differential. Despite competitive pricing and high standard equipment relative to its rivals, especially for the new entry Forté, sales of the AU did not match those of the previous model, the EL Falcon. This was partly due to a lack of enthusiasm by customers for the "New Edge" styling, alteration of fleet sale pricing as well as the long-term decline in the market for large cars. In May 1999, the AU range received a minor update, introducing a bigger brake booster, front power windows
