Why does my Audi 80 produce a burning smell while driving?

I've noticed a burning smell coming from the engine of my Audi 80 while driving. It seems to get stronger when I'm accelerating. What could be causing this and how can I fix it?

It's likely that your car's clutch is overheating, causing the burning smell. This can be caused by driving aggressively or towing heavy loads. I suggest checking the condition of your clutch and getting it replaced if necessary.
