confused.... I m interested to buy a Corolla x 5 or 6 model..... But some people says that auto cars like Corolla x r not gud on cng they give trouble.... Plzzz recommend me... If any one have used it.. Thanks.
Auto transmission cars are not good on gas, but they ain't terrible, just okay. And 4WD, as per my knowledge is not OPTIONAL, but "Full Time 4WD". You'll feel the difference when you take it to hill station in snowfall!
No idea about millage, but 4WD consumes little more fuel than a FWD (2WD).
Sir wasay aadha pakistan CNG laga k ghoom raha hai X corolla mai. If you install Lemda kit then its good, you will feel like you are driving on petrol, you will only feel 10 or 20% different in power. But get it installed from some expert CNG shop, because those who are looser will say that " G yeh to fail hai, falana hai, is ki tuning mushkil hai". But the tuning is computerised, it wont get disturbed that easily.
It gives very good average on CNG.
The troubles you might face will be the:
burning of air filter (slightly) due to backfire on CNG
somewhat lower fuel average on petrol (i guess due to ECU readjustment)
a different power band of both fuel, different response of throttle and specially its behaviour with AC but you will get used to it
check engine light (in case of no connection interception of oxygen sensor)
hard brake pedal (happens in 1000 cc)
