I had read on some forum that Indian customers didn't like Kappa series engines because of poor mileage. I am not Hyundai lover , honestly, but I wrote this post to invite technical arguments and real experiences of kappa users. Maruti Swift had been rated higher than Grand i10 in many forums wining more points on mileage, steering performance and fun to drive, I've used both the cars and can't differentiate on performance, in-fact observed grand i10 a bit better on very lower torque, in very few words one has to learn driving grand i10 and it's not as user friendly as Maruti Swift. The only remaining specification was mileage and I've always been in opinion that it completely depends on your driving style. I've many friends on this forum who complains about swift's mileage as they are observing 12-15 in city conditions. As far as my knowledge goes cars <1.5 ltr engines have a 10K KMs break-in period, so I believe it's yet to get more free and smooth in next 5K KMs for my Grand i10 thus may expect some more miles/ltr in coming days.
PLS NOTE: I am not comparing swift vs Grand i10 ,and the intention is to correct misunderstanding regarding Kappa engines.
