I saw most people on roads speed unnecessary even if they signal 200 metres ahead. I saw people keep their engines on long traffic signals also especially and mostly drivers. some people abruptly speed up raise accelarator at low gears. Poorly maintained vehicles, unnecessary speeding and frequent breaks bring down 40% efficiency down. The above car handling etiquettes should be a part of driving license issuance. I am not surprised with desire claims, if one needs efficiecny, green environment, maximum savings, moderate speed and safe driving - It comes from within and becomes habit as its win win for all.
The figure of mileage achievement on Dsire Petrol and Diesel model are highly impossible and no one will believe it. I challenge the same person to achieve a mileage of 30 kms per litre on any of the Maruti vehicles including Dsire in presence of an independent and non bias expert and let them announce the real result of the mileage achieved by them. This is nothing but a cheap gimmick to attract buyers of Maruti Dsire. No doubt Maruti Dsire is highest selling cars and very fuel efficient but atleast not to the extent it is reported here.
