The big news with the VT Series II is the introduction of the Chevrolet Generation III LS1 5.7L V8, producing 220kW and 446Nm. This replaces the Holden 5.0L V8. A six-speed manual gearbox replaces the five-speed with the V8. The VT II Calais has a new instrument panel, and now features the Supercharged V6 engine as standard. All models now offer the added security of remote central deadlocking (formerly required the key to be turned in the door lock) now easily activated by pressing the Priority Key twice. Turn signal indicators illuminate for 3 seconds to indicate that the car is in a deadlocked state. An electric boot release disable function is now standard, when the Priority Key is used to lock or deadlock, the in-car boot release button is automatically disabled. A battery saver function is a further upgrade to the Series II Commodore's body control module, when the ignition is off, any interior lights left on, including the boot light, will automatically shut down after 60 minutes of inactivity to prevent battery drain. Traction control can now be specified with the V8 as well as the V6 auto powertrain combinations. Cruise control is now available as an option on all models equipped with manual transmission. Exterior styling cues that differentiate the Series II Commodore and identify particular models include revised grille treatments in matt silver and chrome; all-new wheel covers and alloy wheels; clear side and rear indicator lenses; chrome window surrounds; bodyside mouldings and Series II badging. The Calais is further identified by a slim chrome bar on the rear decor panel.
