[Generation IV]

Well its obvious with the VE's first major update the 4-speed will be ditched and probably the base V6 as well. I would predict that the Omega and Berlina will ditch the base 180 V6 and old 4-speed and get the High Output 195 V6 maybe an upgraded version (possibly 200kW and 345-350Nm).

Holden could do well here and invest handsomely into its V6 to get the best out of it, they have 2 good options. There is 2 versions of it right now (the base 180 and the high-end 195) but I reckon Holden should do one of these.

1. Give the Omega and Berlina the 195 V6 (maybe 200 V6 if its modified for the model refresh), and produce 2 versions of the DI 225 V6. One for the Calais, Calais-V, Statesman and Caprice which is more focused on smoothness, quiet running and fuel consumption but still maintaining enough power to lug them around. And another more tuned version (after some typical Holden fettling) to produce around 230-235kW and 380-385Nm for the SV6 and the rumoured SV6-V (luxury V6 to be added next year). The Omega and Berlina to be standard with the 5-speed auto and the DI models to be mated with the 6L50 6-speed auto.

OR

2. Give every V6 model a DI 225 V6 but give the SV6, Calais, Calais-V, and Statesman/Caprice a slightly more powerful version. So the base models wouldn't be lagging behind terribly and the high-end models will be differentiated.
