Worst mileage car in India

The truth about Kia Carens 1.5 Petrol after 2500Kms driven. Cons: 1- Worst mileage of 7.5 Km/l in city and 12 Km/l in highways which no other cars in India gives (tested personally full tank to empty.) Do not believe what KIA says. 2- Useless headlights than any other cars I've seen. 3- Worst engine performance , you do not get instant pickup when you need it, you feel like get down and push the car at times for initial pickup. Pros: Other than what I mentioned above.
