As you know, the current deal Lotus and Vauxhall have is that Lotus cannot bring out a turbo'd elise as that would be direct competition to the VXT and as such would harm sales. It was a similar deal like they had with Rover whereby they could not bring out an Elise with more bhp than the mgf.
However, with the vx finishing production next year, Lotus have "allegedly" secured a deal which will let them use the new 250bhp engine which is due next year in the S3 Exige and a few Elise variants. Given that the Exige weighs less and Lotus are very good with turbo'd engines this could be a real giant killer of a car. (much like the VXR is quoted in Autocar
)
There is still talk/rumours of vauxhall using this engine in a final "VXR" to finish the end of production. It may even use the new 6 speed box which is being put in the new Astra. But I must stresss these are only rumours and as I have said before Stu Harris says they are bo**ocks. I have quoted whits from a few other posts which sort of say what i'm trying to say regarding the rumours of a final VX.
In a couple of weeks production will be slowing down but there is still a contract between Lotus and Vauxhall so there is still just under a years work left. As for there being a special edition to finish with, I think you may be right but no confirmation as yet. The big rumour is that Vauxhall can't sell the cars at the current rate of production which is why we're slowing down
I've already said the same thing in another topic so I'll keep this short:- There's another yers production left, probably will be a special edition to finish, 250bhp engine is only a rumour, at the moment
