Just because it's a diesel, doesn't mean it pollutes excessively. I looked up the COČ emissions (I like this keyboard
) for the Touareg and the X5. Here's the data:
VW Touareg V6 TDI: 262g/km
VW Touareg V10 TDI: 333g/km
VW Touareg W12 petrol:
375g/km
X5 3.0sd: 216g/km
X5 3.0si: 244g/km
X5 4.8i: 286g/km
