I had bought XZ+ S variant on Oct 2021. Car's performance is very good and I heard few complaints earlier where no better mileage and noises from engine. Till date I haven't faced any noise issue. And the vehicle's mileage depends on driving. I drive in economy mode and I accelerate only if needed and will drive between 90-100 kmph. I have got a max mileage of 30 km/l while driving from Bangalore to Salem. It's bit downwards and tats y such a high mileage may be. Otherwise, in city I get a min of 14 km/l and highway minimum of 19-20 km/l. I had calculated all these things before buying only and I am very happy that I get more mileage than the claimed numbers. I had driven Continuous driving from Bangalore to Chennai and immediately from Chennai to Bangalore and didn't face any issues. Close to 12 hrs. continuous travel with lunch and tea breaks. I love my vehicle and not facing any issue till now. Worth the money for sure. you will never regret !!
