although I hate diesel fumes, I'm looking with interest towards honda's small diesels(in order to buy used one in 5-6 years.. before tesla model S deprecates enough if it ever happen
)
can not ignore the fact of >20% more efficient combustion cycle, petrol could not get close to that
1.6dtec is aluminium as well now, so it should bring down warm up times and weight diff
re: DMF, is it just bad engineering? they somehow deal with torque on much more high powered cars including trucks. surely it's manageable on 1.6 diesel
re: reliability, that's interesting, how existing honda diesel engines compare to their petrol ones? 2l dtecs were around for quite a while to give some stats, although my last few searches did not bring much info
