[Auto Talk] Can regularly shifting to Neutral on an automatic gear damage it? - Page 3

If you keep your speed at a point just after the shift point for your automatic you will get the most fuel economy.

Can improve fuel consumption by tail gating

because this reduce drag but not advisable.

My car don't have gears cos is CVT

but I don't shift to N even at traffic light because my CVT box is expensive and might cos more wear and tear. Anyway, the box is design to disengaged even in D when idling for sometime.

The reason high-rev during down hill is that your car micro-processor detect going down hill so the auto gear would shift to lower gear so that engine braking can happen for safety reason, correct me if I have wrong understanding.

This is so true... I hadn't realized it for a while until I did a test on the same patch of highway. Drove it a various speeds, and the 90km-95km/hr mark seemed to be the sweet spot in terms of fuel economy/speed. After 100km/hr, my fuel mileage dropped and only got worse as I went faster.

My father actually tried driving on trunk roads at 80km/h and claimed to have improved mileage. I wouldn't do that just to save fuel even knowing the fact. I just "cruise" at 110km/h on highway.

I can confirm this too. driving at 80-90 on the highway definitely saves a LOT of fuel.

So if ya someone is tailgating you look for a WD sticker on the windshield before resorting to road rage ... it might just be Mike trying save some petrol

True on drag and draft though !!

test drived a Golf GTI with DSG. super smooth, hardly feel the gear change

but fuel compsumtion will be a lil higher

DSG is way more efficient than standard auto

2.0T FSI (same as those used in Audi A4)

but the pricetag is the main killer

VW Passat with 2.0T FSI is my favourite. 200bhp, perfect!

we all should just cycle, no petrol, no gearbox, save the earth!
