, and an electrically retracting power antenna were now standard. The naturally aspirated 3.8-litre Ecotec V6 came standard on the Executive, with the option of the Supercharged Ecotec V6 or Gen III V8 engine. V6 engines were coupled to a five-speed manual transmission, and V8s came with a six-speed manual. A four-speed automatic transmission was available as an optional extra, regardless of the engine choice.

Commodore Acclaim

The second tier Acclaim was marketed as a family-oriented variation of the VX range, with a strong emphasis on safety. Building on the equipment levels of the Executive, the Acclaim also featured four airbags, cruise control

, traction control, four airbags, 17-inch alloy wheels and the Supercharged Ecotec V6 were offered as options.

Commodore SS

The SS continued on with the sporting trend of the Commodore S, but incorporated bumper-integrated foglamps, and more aggressively styled alloy wheels. Instead of the six-cylinder engine standard on the "S pack", a Gen III V8 engine and six-speed manual transmission came as standard. A more advanced suspension setup, traction control and a passenger's airbag were also standard, but side impact airbags and leather upholstery remained optional.

Berlina

This model and the top-of-the-range Calais attributed a notably re-styled exterior, when compared to other trim levels. Both featured a full-width rectangular grille
