The new 2014 Infiniti Q50 was first thrust upon us in at the beginning of the year at the Detroit Auto Show before it continued its publicity tour of the world motor show circuit. But as we know, publicity never really ends.

The luxury vehicle devision of Nissan has continued its PR by giving the model a new look with thanks to top fashion designers, Zac Posen and Thom Browne. Each designer created their own version, both of which will be sold for $75,000 each with proceeds benefiting St. Jude Children's Research Hospital.

The Thom Browne 2014 Infiniti Q50 benefits from additional chrome inserts on the exterior while the interior is upholstered with the designer's signature red, white and blue stripes and a sterling silver ring encircles the gear-shift handle.

Posen's creation meanwhile boasts a new exterior livery that evokes the back of a glamorous silk gown.

More details are available in the press release below.
