I have never used any 1.6 ALTIS , but have driven AXIO 1.5 few times , and if i compare it with my ex-ride ALTIS 1.8 Cruisetronic S/R then ;
Acceleration -- 1.8 Altis was very fast
resale -- Both are equally bad
comfort wise -- Axio
Consumption -- 1.8 Altis has very bad consumption , but newer 1.6 Altis is very economical !
If ur main concern is acceleration then y are u considering two decent family sedans ?? if u compare 1.5 axio and 1.6 Altis , then Altis has good acceleration plus its economical too , u will get Cruise control and Sun Roof , a better looking car , tension free ride for 5yrs ( brandnew ) plus warranty !
comfort wise ,quality wise , road grip , driving pleasure , yes Axio 1.5 is better than Altis !
