Aura's middle model (S CNG) in only 9.0 L including accessories is good. Driving experience (1.5 years) is very good. Looking like a sports car in silver color from the rear side & a superb LED tail light. Service cost is normal. Its horn is Mind-blowing. Highway Avg. is 26. ( Company claim 28). If traveling on highways daily basis & if drive 70-80kmph speed with AC ON then maybe you can get 28 to 30 milage. It Depends on driving.
