"Over 6,000kg IC that is zero emission seems to be better."
Too bad it's not possible to have 'zero emission'
ALL vehicles gas, lpg, diesel, electric all contribute to CO or CO2 emissions in some form or another, always have and always will.
The only way to achieve a true 'zero' emission is to just not have any, go back to the horse and buggy days.
Then the environment fanatics can start picking on wood burning and cow farting!
:oD
