The correct model lineup for VE/WM is as follows:
Omega Base
Omega with Safety Pack (Active Head Restraints and Curtain Airbags)
SV6
Berlina
SS
SS V-Series
Calais
Calais V-Series
Statesman
Caprice
All models come standard with Dual-Stage Front Driver and Passenger Airbags, Side Airbags, ESP and ABS.
This has been confirmed and than cancelled many times but there is a possibility of a sports pack on the Omega.
Spec of Base SS similar to current SV8 and SS-V has spec of current SS (with upgrades introduced with SS-Z).
A price premium of a couple of thousand dollars over BF Falcon is planned.
Ute is internally confirmed for August 2007 and Wagon for early 2008. Ute mirrors Passenger car lineup with Base, SV6, SS and SS-V models. Looks very cool - tub sides slope downward from front of car to back. The wagon is much more of a 'Sports Wagon' than the current wagon, think Saab 9-3 SportCombi in terms of theme. VZ Crewman to continue until 2008 with no replacement planned.
Realistically the Omega will be more expensive than Falcon XT, but it will have features that are over and above what is offered in Falcon Futura. So in reality the value for money proposition in VE is probably much better than the current car and in retail you are selling value, not a price. In effect there will be no 'poverty-pack' in VE. I personally think this premium philosophy is at odds with the recent strategy encompassing TK Barina and JF Viva but that's what will happen.
As for engines, all I'll say is there will still be two V6 engine specifications neither of which will produce more than 200kw. The base V6 is to get a variable-length intake manifold but no VVT on exhast and new cam designs optimise performance and efficiency and new cam chain designs optimise NVH (To stop the wheezy noisy top-end nature of the current engine). Gear ratios have been selected very carefully to optimise fuel efficiency in base V6 equipped models and for response in premium V6 equipped models. The new SV6 is quicker to 100kh/h than the current car even with a weight penalty.
Contrary to what much of the media has been suggesting, the 4-Speed Auto Trasmission will continue in base model Omega. The updates included with EuroIII (sensor on output shaft etc.) have improved the transmission's responsiveness and smoothness markedly. Omega is the only car in the range with this transmission. The French made 5 Speed is just too expensive for the base car.
