https://en.wikipedia.org/wiki/Diesel_exhaust edit:so as not to be hyprocritical we actually traded our 120D yesterday for an Audi Q3 TFSI Quattro-1.4l turbo petrol with virtually identical mileage figures but markedly less emissions.
it`s faster but low on torque so will miss the grunt of the 2.0 TDI.
(pretty sure it was used in one of the first hybrids to win Le Mans and is still being widely distributed.
my 96 diesel hilux will cost me $4k to convert to gas-it`s a farm vehicle worth $10k and is only used for fuel and wood runs so that is also a moral dilemma for me.
but where do you start-reducing your carbon footprint is easy but inconvenient.
I am typing on a solar powered laptop,grow much of my food,am totally off the electricity grid,gather all water and dispose or recycle all my sewerage and rubbish,but believe me,it`s a lifestyle choice and i honestly envy my peers with their aircon and unlimited power and water...........
life is a dilemma
