I am using Hyundai Eon since last 6 months. Eon is an affordable hatchback car with decent interior and design. I believe Eon takes on small car like Maruti Alto and Tata Nano.
Eon drives power 800 cc, 3 cylinder petrol engine, 5 speed manual gear and small look is best for a city car. Per my experience it will give around 21 kmpl on highways.
Eon provides comfortable seating for 5 passengers. Car fitted with audio CD player with radio, USB connectivity and AUX in supports is made for complete entertainment.
Overall its small concept car for city ride.
