Car Badge Challenge: Urine Edition

Since I thought it was so engaging last week talking about car badges and giant snakes eating/mouth-birthing people, I decided to dive into the arcane world of car badging a bit more. This time, though, to make it more fun, let's have a little riddle/contest thing. You ready?

Here's the question:

I can think of only one automotive badge that was strongly influenced by the presence of urine. What car company used this badge?

I really have no idea if this is commonly known or not, but I guess we'll find out! I'll check the comments to see who got it right. I'm sure you'll think more badges need to be urine-inspired.
