Fiat Chrysler Automobiles has reportedly rebuffed PSA’s merger advances, but it appears the two companies could still be holding talks.

According to Bloomberg, the automakers are exploring a potential partnership to create a so-called “super platform.” Little is known about the proposed architecture, but it appears the platform would be designed with the European market in mind.

A lot of details remain unconfirmed, but it’s believed the joint effort would lower development costs. The new platform could also give FCA a chance to revive its struggling European lineup.

One person familiar with the talks told Bloomberg the discussions could be officially announced by the end of the first half of the year. If the talks are successful, insiders believe the scope of the partnership could expanded in the future. There’s no word on specifics, but people told the publication the tie-up would likely involve joint investments in new electric vehicles.

Last month, reports surfaced that PSA was exploring collaborations or mergers with several automakers. PSA CEO Carlos Tavares was said to be particularly interested in a partnership with either FCA or General Motors.

FCA CEO Mike Manley hinted he was open to the possibility of a partnership as he used to the Geneva Motor Show to say he would look at “any deal that would make Fiat stronger.” Despite this, reports surfaced last week that FCA ruled out the possibility of a merger as the automaker didn’t want to increase its expose in Europe – among other things.

Given this rumored reluctance, it seems odd that FCA would now be interested in a European focused joint platform. However, only time will tell if the rumors pan out.
