But is this list any use to you, the low Co2 output indicates good mpg figures?
Best in class: Honda Civic hybrid, 109g/km Best of the rest:
Ford Focus 1.6 TDCI 90 Econetic, 114g/km
Ford Focus 1.6 TDCI 110 Econetic, 115g/km
Renault Megane 1.5 DCi 80, 117g/km
Ford Focus 1.6 TDCI, 118g/km
Not much use really, because none of the Focus models are sold in Ireland (1.8 (band b) and 2.0 (band c) tdci only on sale here at the moment, according to the Ford website).
I listened to the piece on the Last Word alright. First one was Fiat Panda 1.3L Diesel. Followed by the Yaris and I think it was a Golf (all diesel from what i can remember). With the Panda at number one, you get the general idea that this was a classless list based purely on the most fuel efficient set of four wheels on the road.
Someone else may be able to fill you in as regards the rest.
