Although i think you will find 'Group N' in this case has nothing to do with rally - it's just a product name
has nothing to do???please if it is only a product name explain us from where the characterization "Group N" was been birth?.....
refering to this-give us your explanation-:
From Wikipedia, the free encyclopedia
"In relation to
motorsport governed by the
FIA,
Group N refers to a set of regulations providing 'standard' production vehicles for competition, often referred to as the "Showroom Class".
This contrasts with the
Group A all-out competition production-derived vehicles. Group N cars are limited in terms of modifications made from standard specification. Group N was introduced by the FIA in
1982 to replace the outgoing
Group 1 as "
standard touring cars".
The range of modifications allowed is quite narrow - few mechanical engine modifications are allowed (save for lightening within set limits and baffled sumps) although the choice of
ECU is free, and this can liberate some extra power itself, and most of the modifications allowed are to promote longevity rather than increased performance, although the boundaries of these two areas are blurring. Furthermore, cars with
forced induction engines are fitted with a restrictor in front of the charger to limit power.

Originally, Group N meant that all the interior trim had to be present (including the rear seat), whereas this has now changed to allow removal of the trim aside from the dashboard and replacement of the door trim. The springs and dampers are free, as are the internals of the gearbox, providing that the homologated gear ratios and gearchange pattern are respected. This allows the use of 'dog' engagement gearboxes, providing quicker gearchanges and longer gearbox life. There is provision for strengthening of the suspension components and bodyshell, providing this doesn't alter the operating principle.
The FIA and many national motorsport associations are moving towards making rallying championships based in Group N, in an attempt to reduce costs, reinforce the link between motorsport and the car that the member of the public drives, and to reduce the environmental impact of motorsport."
