A diesl would be quicker round a track standard vs standard.
Dont forget a dci makes more power than claimed
65dci ~70hp
80dci~85hp
There not much in it in a stright line the 1.2 16V is slightly quicker but you have to realy get the revs up and hammer it on the motorway. Thats agianst my 65d ci a 80 is a bit quicker so should sliglty be quicker.
