Hmmm, very interesting
The car base is Japanese, but didn't have this down as a Ford at all! Rather, I had it as a Mazda 323 Coupe proposal (pre-Mazda MX-3 coupe) although of course the 323 was used as a base for many Asian-market Ford-badged cars (Laser, etc.).
The car was noted as a Mazda 323 Coupe in the Swiss Automobile Revue in 1986, plus is captioned as such in the new French book about the design career of Patrick Le Quement, so you get a point for correctly identifying him as the stylist anyway.
As Le Quement worked directly for Ford of Europe, and indirectly for Mazda, I am happy to concede that this car may have been a Ford and a Mazda, so your point is safe. I don't have a copy of the new Le Quement book as yet, but if you get chance to look at one, this car is pictured and mentioned half-way through.
If anyone has any more information to add about this as either a Ford or Mazda, it will be interesting to see it. Thanks.
