Prius, if you're after an ugly car.
Civic hybrid, if you're after something that looks decent.
I have been using a Civic hybrid since 4 years now and it gives me 16-17 kml. The car has a 190k kms on the odometer. The people who tell you that it has a bad fuel average are people who may have been scammed into buying a salvage auction car which come from the UK/Japan (probably a CAT C or D write off). Most Jap imports have reversed odometers.
