Got my Santro XO erlX fully loaded from Trident Hyundai Bangalore this year Feb 2006 .I use to drive 50 KM daily and I must say here that I am really very much satified with the performance and mileage. I am getting 15.4 KMPL as on average , both in bangalore city traffic and highway drive with out AC on .
On Highway the car is really Zooooooming !!! with comfort & nice road grip at speed of 140 KMPH.
I was to compare among Wagon R and Santro Xing, and the only reason I didn’t go for Wagon R is Look , sitting comfort. I could not comment on Engine Technology as I am not mech Engg , but being as end user I noted Santro Xing Engine displacement is slightly higher with 1086 CC and PS 63@5500 rpm
