During last summer when gas prices went out of sight, I engaged the ECO
(economy) setting on my 2013 Elantra GLS. It certainly did save me some
gas, and I was happy with the performance.
Well, since then, gas prices have dropped somewhat and I can afford to turn
the ECO off. Having done so, the Elantra is driving like it has a super 6
cylinder motor in it, whereas with the ECO system engaged, it felt more like
a 4 cylinder engine.
I drive mostly in the city on short hauls and although I'm finding the gas
economy is not as good, the smoothness and power from the engine more than
makes up for the cost difference.
On saying that, if the cost of gas goes up to $1.36/litre (I live in
Toronto), I will once again, use the ECO and live with the performance
difference. Money = Power. What else is new?
