Mad Max-type Sci-fi movie from the mid-80's with fat blob men

Question

For many years I've been trying to ID a mid-80's cult sci-film that I saw as a kid on TV in the UK. It must have been aired around the late 80's.

My recollection is sketchy but it had a Mad-Max setting, (dusty/rocky landscape) and featured a man with a armoured car. His pal, a black guy, had a larger rig that he drove around in. They both wore light body armour.

The scene I remember was when he tried to escape from a horde of pale, bloated, obese men/creatures who jumped through large tubes and ended up in a small underground bunker.
Yep, sounds weird and it is.

Answer 1

This is Spacehunter: Adventures in the Forbidden Zone

It's very Mad Maxy, with post-apocalypse-standard vehicles etc. All the other points you mention match.

Did the babies look like this?
