Has anyone else experienced this, or is it just me (in which case I'll contact my dealer)?
My i30's a couple of months old - done about 2000 miles. I notice that it really doesn't like being driven with the revs below 1500, becoming slightly jerky and requiring a lower gear.
While it is a bit disconcerting the first couple of times it happens you soon learn to stay in 4th if you are going to drive at much less than 70kph for any length of time...I personally wouldn't sacrifice any top end performance to reduce this judder...
This business of being pushed along at low revs - mine doesn't do it. Maybe it's not allowed in the UK?
My 1.6 i30 crdi auto has done about 2000 klms. I find that when travelling at 70kph at 1500 revs and attempt to accelerate slowly ( to keep up with traffic) it does not change down but tends to 'labour'. with further accelaration it changes but this is not always possible in close traffic. i can select 3rd however this defeats the purpose of auto. Has anyone else had this problem? I am concerned about damage to either the engine or gearbox.
this is probably what Sweetbix ment about petrol and diesel, she said the diesel was less responcive than the petrol when she test drove both, but she did not say if they were manuel or diesel, but i enjoy driving a high torque motor in auto more than a low torque motor that kicks back a gear to keep the revs up, i don't like auto's kicking back a gear all the time. but just me. if your motor feels like it is labouring just manualy shift it out of overdrive, easier on the trans too.
Thanks for the advice, perhaps I'm 'babying' it a little. I' ll try a more aggressive approach and let you know.
The peak power is at about 2750 rpm so there would seem to be no point in letting the revs go above this.
the older she gets the better she gets.

Torque is measurable... Power is derived... like this..... Power (kW) = (Torque (Nm) x RPM) / 9549 or Power (hp) = (Torque (lb/ft) x RPM) / 5252Which is why Petrol engines usually have more Power than the diesels... the torque arrives at a MUCH higher RPM in the petrols and therefore, in the above formula's, makes a MUCH higher numerator in the fractions on the right side of the equations.It's been said that: They sell Power; You drive Torque.
are you a rotary man?
