I bought my new toyota etios diesel model car on march 2013. So far Ive done 5000 kms on this car. Really it is a nice car, where the handling and breaking of this car is awesome. Another important point on this car is the rear space and boot space. Really it can accommodate 3 ppl well in rear seat and boot space with 595 litre is more than enough to keep any number of luggage. It is a wonderful car for highway travel and very comfortable also due to its soft suspension. But it scraps very big speed breaker when it is fully loaded even it has 174 mm of ground clearance.
Mileage(Tank full to tank full method):
city: 16 kmpl
Highways: 18 kmpl(130 to 140 kmph) to (100 to 120 kmph)20 kmpl
I reached till 140 kmph but I didnt keep constantly on it but car was very stable in 120/130kmph. In this I felt figo is the winner because I reached 155kmph easily but mileage went down below 16 kmpl because of this speed.
Toyota always rock in the terms of quality and cheap maintenance. I heard qualis, innova is used to run more than 5L of kms without any trouble and even corolla also. Hope etios also have same engine life and reliability.
