I have a manual 1.4 S. I drive it with the Sport button on, I know it's mainly illusion, but the steering does tighten up and it feels a little sharper. Wondering if the Sport button affects fuel economy at all?
 
The steering only changes below ~40km/h. The 1.4 doesn't change engine mapping like a TA.

The EPAS motor is rated at 1.5hp, when it's working hard in normal mode that can cost you fuel. In the city, I'd wager Sport mode is the more economical.

haha interesting to know that but i really dont like sport mode as the throttle is way too sensitive. above 100 kmh the steering is the same regardless anyway.
 
I notice that sport in manual (dual logic here) mode can very efficient and certainly enjoy driving it this way. I don't like it in auto because it doesn't change up quick enough when I am trying to drive it gently so I use manual when in sport.
 
So reading the Fiat manual, there are actually three different modes in the 500!

I assumed that in a car with a City/Eco button, normal mode would be the same as Sport on a car with the Sport button. Not so. I only wish it told me how to get Sport on my Eco button car. Looking at the wiring diagrams it seems like the software is there, just need a different input. It also looks like you can disable EPAS altogether without disabling ESC. A project for another day :D

I have 1.4s manual. I'm sure it feels more lively in sport mode. Sure the steering gets a little heavier at slow to zero but it definitely is a livelier drive. Throttle is more sensitive and you can get a jerky ride as you come off the accelerator but I do prefer with sport engaged.
I ran it for a week without sport and I think economy was improved but not a huge difference. I drive it pretty hard at the best of times!!
I might be wrong but I leave it on all the time now.
Cheers

I'm not sure about engine mapping etc, but if I want a livelier drive the Sport button, I agree, does make a difference. If I'm in peak hour bumper to bumper traffic I switch it off, the performance does seem a little duller with the Sport button off.

Are you sure engine mapping doesn't change, the car does perform differently- it's livelier and sharper with the Sport button engaged.

It doesn't change engine mapping, but it does alter the pedal's sensitivity. Some hypermilers have tested the effects of a less sensitive throttle and found a 3% economy gain. Personally I prefer instantaneous and linear response. If you have an OBD scanner you can hook it up and watch the TPS value in different modes.
