Not in France: in fact, one of the explanations given in 2000 was, besides the European normalization, the fact that most automobiles makes unveil the changes during all the year, the July change being nothing more than an administrative marker for years...
This said, French magazines give lots of "what's new in 2020 automotive lines" articles, from December to February, and so do web sites (see here or here).
And among the French makes, if PSA seems to sprinkle new models and changes all along the year, Renault apparently prefer to stick to January (or close), even for trucks.
