The Holden VZ Commodore is the thirteenth model of the Holden Commodore lineup, a full-size car produced by the Australian automotive marque, Holden. Released in August 2004, the car debuted a new generation of 175 and 190 kilowatt 3.6 litre Alloytec V6 engines in place of the older 3.8 litre ECOTEC V6 engines. These new Alloytec DOHC engines have carried on through to the VE Commodore which was released in August 2006. A new 5L40-E 5-speed automatic transmission sourced from General Motors was introduced on the sports and luxury V6 variants. The VZ is notable for being the... only Commodore series of recent times to not officially introduce a Series II update to the range, however a number of mechanical changes were made in January 2006. Holden introduced the new L76 6.0 litre V8 to its range. The V8 has been slightly detuned, and both Displacement on Demand and variable valve timing have been removed.
