Youtube usually recommends me this tractor pulling videos, most of the time when the engine blows. It is awesome but the thing I'm most impressed/"disgusted" is the huuuugggeee dark smoke column from the exhaust, I'm like wth! there goes another hole in the ozone layer. Is that because most of those engines are diesel?
A diesel engine will make more power relative to the amount of fuel it is fed.
Nothing about motorsports is green, including the electric cars.
