What does the 'eco mode' feature do on a Ford Focus?

I just bought a new Ford Focus and noticed there is an 'eco mode' setting. What does this feature do and should I be using it for all my driving?

The 'eco mode' is a setting that optimizes your Ford Focus' performance for fuel efficiency. It adjusts the engine and transmission settings to help save gas. It's a great feature to use for everyday driving, especially if you have a long commute or want to save a little extra money on gas.

I've found that the 'eco mode' can make the car feel a bit sluggish, so I only use it for highway driving. The fuel savings may not be as noticeable in the city, and you might prefer the smoother acceleration of the normal driving mode.

I wouldn't recommend using the 'eco mode' for driving in hilly or mountainous terrain. The car may struggle to maintain speed on inclines, and you could end up using more gas than necessary. It's best to switch back to regular mode in these situations.
