There are Powertrack experts and there is Mark! Mark has kindly provided this photo of this Spiderman Race & Chase set from his own collection.

The key differences here are not just the provision of the red Spidercar but the fact that this is a traditional PT-6000 layout complete with tip-up bridge.
Owing to the large amount of French on the box I suggest this set was produced for Canada.

There is also a possibility it was sold in the US in 1980. It could have been an exclusive for a high street chain store or catalogue shop?
