Mileage:
Filled up tank again to get 2nd mileage reading - 234KMs/27.56L =
8.5Kmpl.
A/C always ON - 80% City driving (bumper to bumper) around 20% of non-stop-and-go driving. 70% driven by wife (relatively more sedate driver than me), 30% by me. I'm satisfied with it.
(For reference: My earlier/first mileage reading had read 76KMs/9.86L = 7.7Kmpl).
City Drive (as compared to Santro AT):
It is definitely bigger in size - hood is longer, car is longer and wider. So I feel I have to compromise on the maneuverability in the city. I also made an error in judgement and got my first 3" scratch.

At crawling speed, while trying to pass thru two pillars erected to keep large vehicles away from a residential area, I turned left too soon, even before the rear of my car had cleared the pillars. The bottom of the rear door scratched that pillar and left a 3" dagger thru my heart. Gosh, it hurts!
There is a marked difference in how the Santro AT changes gears and how this one does. I still haven't got the hang of when this AT changes gears - I don't drive this car often, my wife takes it to work. I drive the Reva.
Highway drive:
Even though we did not make the planned trip to Mysore, we still managed to break free of the city bumper-to-bumper traffic briefly and take advantage of i20's power. In short it was a breeze.
There was plenty of power even without going beyond the 3K RPM to
overtake buses and taxis. Not only there was power, it was delivered when needed i.e. whenever I pushed the pedal harder, the AT shifted gear downwards, sped up in lower gear, and shifted back upwards automatically when I let my feet off the pedal.
Since I'm new to the car and it's also a little bigger to my comfort, I planned each overtaking. Question is, how would it behave in unplanned overtaking - I don't have an answer to that yet. I need to put more KMs behind me to get to that comfort level.
High-speed
handling is not an issue. I did overtaking at 70+ speeds by changing lanes from left to right, then back from right to left, didn't feel out of control ever. I'm still on stock 185/65 R14 Apollo Acelere and find no reason to change.
Steering is something I always have to be conscious of in this car. Like I said earlier, I don't have problems turning the car, but I do have problems while straightening the steering wheel after completing a sharp turn - I always have the fear in the back of my mind that after completing a sharp right turn, while straightening, I/it will oversteer to the left lane. Again, I'll blame it on my wife. I don't get to drive the car enough to familiarize myself with it.
I felt the
headlights, especially the high-beam range, was inadequate while driving on ORR/Sarjapur Ring Road in the night. No, I'm not a habitual high-beam driver. Whenever I felt a need for it, it was not sufficient when I switched it on.
Next report after a really long drive.
