Prices will start at £14,645 for the 1.8LS rising to £20,980 for the top of the range GSi.
The model line-up has been simplified to include three 'luxury' trim levels – LS, Elegance and Elite – and the three 'sport' models, SXi, SRi and GSi.
From launch there will be three petrol and two diesel engines on offer, the 1.8 16v, 2.2 16v and 3.2 V6 petrol units and a 2.0DTi or 2.2DTi turbo diesel.
There will be restrictions to the engine choice. All GSi models will get the new 3.2 V6, while the SRi will be powered by either the 1.8 or 2.2 16v petrol, or 2.2DTi. The Elite is available with all engines.
In comparison to the existing line up, prices vary. For example, the new 1.8 LS is up £365 on the old one. There are also price reductions. 'Like for like' examples include the new Elegance 1.8 at £16,145, compared to £16,430 for the outgoing CD 1.8, and £16,645 for the 2.2 16v Elegance, against £16,695 for the CD 2.2.
Understandably, the new Vectra is priced competitively against its main rival, the Ford Mondeo which ranges from £14,595 for the LX 1.8 five door to £20,445 2.5 V6 five door.
