Audi Q3 concept (Cross Coupe quattro)

[Jas11n]

Just been reading up on this, bumph says it uses a 2.0 TDi lump pushing 204bhp.
A part of the stuff I was reading caught my eye though;

The engine is fitted with a diesel particulate filter and the VW Group's Bluetec system, which injects urea into the exhaust to cut emissions of harmful nitrogen oxides. The Bluetec system enables the engine to meet Euro VI and US emissions standards, and Audi claims the car will manage nearly 48mpg on average.

Yes, it injects "urea" into the exhaust
My empty head seems to remember my biology O-level lessons at school telling me urea is the main component of "p*ss" (yes I do remember it being the first organic compound to be artificially produced from inorganic base compounds )

Great bragging rights down the pub that one eh?

[Knobby] "My cars got direct petrol injection, or FSI for short"
[Norbert] "My car is a TDi, so gets better mpg"
[Knobby] "My cars got more power than yours"
[Norbert] "Mine pumps piss into the exhaust, so there"

[Knobby] "Fancy a pint?"

You can just imagine that. "My car pisses all over your car. No. Really. It does!"

Urea can be related to "piss" as you suggested. It is also a component of fertilizer and those nasty fertilizer and diesel fuel bombs <opens up a whole new line of jokes>.

VW/Audi will be licensing the BlueTec technology from Mercedes-Benz who developed it. Mercedes-Benz says its BlueTec technology cuts nitrogen oxide (NOx) emissions by adding a urea-based solution into the exhaust stream.
