I'm looking for a book I remember from when I was a kid (20-25 years ago in Australia), I think it was about a dieselpunk society of animals. At least I think it was dieselpunk, as I remember that most had souped up bikes or cars, or maybe even were implanted/merged with the tech.
I remember a dark and gritty city, possibly with different gangs on the streets.
I think that the physical size of the book was a large format, like the size of Asterix or Tin Tin. It was also in color, and I think it was in English since I did borrow it and I didn't tend to borrow books in a language that I wasn't able to read.
Unfortunately I'm not able to remember any plot points or characters from so long ago, but I do remember that some of the animals were large ones like rhinos and elephants.
