The Holden VT Commodore represented one of the most significant updates to Australia’s best-selling large sedan when it launched in 1997. The VT series introduced a completely redesigned platform compared with the outgoing VS Commodore, bringing major improvements in chassis design, safety systems, electronics, and drivetrain options. Designed to modernise the Commodore for the next generation of buyers, the VT offered improved ride comfort, better structural rigidity, and expanded equipment levels across the Executive, Berlina, and Calais model range. With the later introduction of VT Series II, the model also gained the new Gen III 5.7-litre V8 engine, replacing the long-running Holden 5.0-litre V8 and marking a major technological shift for Holden performance vehicles.
Engine Options
The VT Commodore was available with several engine configurations designed to suit both everyday drivers and performance-focused buyers. The standard engine across most models was the 3.8-litre Ecotec V6, delivering strong reliability and good fuel economy for a large rear-wheel-drive sedan. Higher-spec models were available with the supercharged version of the same engine, producing significantly increased torque and stronger acceleration. VT Series II introduced the all-new Gen III 5.7-litre V8 engine, an aluminium-block design that delivered substantially improved performance and efficiency compared with the previous Holden V8.
• 3.8L Ecotec V6 — 147 kW and 304 Nm
• 3.8L Supercharged V6 — 171 kW and 375 Nm
• 5.7L Gen III V8 — 220 kW and 446 Nm
Transmission Options
The VT Commodore was offered with several transmission choices depending on engine type and model specification. The majority of vehicles were fitted with a four-speed automatic transmission, while V6 models could also be ordered with a five-speed manual gearbox. With the introduction of the Gen III V8 engine in VT Series II, Holden also offered a six-speed Borg-Warner (Tremec) T56 manual transmission, providing improved performance and lower engine speeds during highway driving.
• 4-speed automatic transmission
• 5-speed manual transmission (V6 models)
• 6-speed T56 manual transmission (Gen III V8 models)
Electronic Systems and Vehicle Features
The VT Commodore introduced several upgraded electronic systems designed to improve driver convenience and vehicle reliability. An upgraded Body Control Module (BCM) provided additional functions including remote deadlocking, battery-saving lighting control, and courtesy lighting activation when the ignition is switched off. Electrical system efficiency was also improved by significantly reducing standby current draw, helping to preserve battery life when the vehicle is parked for extended periods. Other updates included revised instrument cluster diagnostics, updated exterior lighting designs, and expanded interior trim and equipment options across the model range.
Vehicle Identification Information
Like all Holden vehicles, the VT Commodore uses multiple identification plates and coded markings to record vehicle specification details. The Vehicle Identification Number (VIN) is visible through the windscreen and is also stamped on the vehicle structure. Additional identification plates record details including engine type, transmission specification, suspension configuration, paint colour, and trim combination. These codes are essential when identifying the exact vehicle configuration for servicing, replacement parts, or restoration work.
