My car; i30- Diesel 1600 Auto. Comfort.

I have read that the auto. gear box is only 75% efficient.

Users 25% more fuel, than manual gear box.

Cannot future Hyundai's have a  more efficient auto. gearbox?

Cannot future Hyundai's have a  more efficient auto. gearbox?

Most of the newly developed Hyundai Models (e.g. IX35, I45 etc..) Have much more efficient 6 speed Auto boxes now

and as myself and other members have mentioned before,the 2012 i30 will most likely have some major mechanical upgrades.
well the front,rear and interior have major upgrades,i imagine the running gear wont be forgoten.    IMO.

Most auto boxes use a torque converter which causes the inefficiency - even when they have lock-up.

I have had two Audis fitted with the twin clutch DSG gearboxes - you can drive them as manual or fully auto. The gear changes in auto are hardly deciptible and I used to get better economy in auto than in manual - the gearbox was obviously a better driver than me.

Other manufacturers have followed suit and developed multi clutch boxes that are equally efficient.

So if you want an auto with manual economy - buy a car with a DSG gearbox or its multi clutch equivalent.

The new 6 speed i45 while not a DSG clone is more economical as an auto (7.9 LPH)than it is in manual form (8.0LPH I think)
