SIAC have nothing to do with ROVER pal, that name is owned by JAGUAR/LAND ROVER (TATA) so there could possibly be some in the future as there is no current 'super mini' or 'small hatch' in the Jag range, perhaps they could bring ROVER back in order to fill a gap in there model range, might be dreaming though.
Have to say, now more than ever, with JLR's profits going skyward (cosiderably more profitable than BMW given how many units BMW shift) this is the best time for JLR to widen their appeal by the use of the Rover brand without tarnishing the Jag or LR brands in the process.
There is definitely room for them to become more mainstream and clearly using Jag or LR is NOT the way to do it. I suspect, very strongly, that TATA will use Rover at some time in the future for a number of reasons:
1) Using the TATA brand will be difficult, it has no image and attempting to emphasise links with JLR will harm JLR more than it will do TATA good.
2) JLR has an increasingly strong image and could now bestow some of that positive image on Rover which rather than be seen to be a old hat dead brand, could instead be perceived to be a quality JLR family product. This would seriously breathe new life into Rover and I don't think, given the crest that JLR is riding, would harm them at all.
3) The small car market is clearly the way the world is going, look at the latest SMMT stats that back this up and predict even more growth. JLR and Jag will never have a "small" car, they do not fit the brands and would harm them. However, an exciting, well designed car for the segment with a Rover badge - linking it to LR indirectly (kinda the same way MINI has been to BMW) would be a logical way to fill that gap.
