Tucson revgt vs sportage revgt

Dear all,

I am choosing between the two (both diesel variant)

I have been to the hyundai casa and they gave a good deal on the tucson. Will be going tomorrow for the sportage to inquire.

Test drove the tucson diesel already and was quite surprised on the "hatak" and the "speed". I thought it was a gas engine at first!

Will be used by my mother for city driving most of the time

Questions are:

1. Which is more fuel efficient? Could you post figures? For city driving.
* they are the same engine im sure, but the tucson has 4wd. Will that affect fuel consumption??

2. Does the sportage have same gear ratios as the tucson? I loved how the tucson drives.

3. How is the ride of the sportage compared to tucson?

4. I noticed that the sportage has lesser space at the back seat? Am i right?

5. Do they have the same maintenance parts?

Reason why im asking is it is hard to get a test drive on the sportage diesel. For me. Exterior and interior. Id go,with sportage. I am just almost sold on the tucson because of the name and reliability.

Thanks for answering!
