believe me or not
Alto on CNG maximum goes to 140km/hr-145km/hr
Coure is far better than Alto, It touches its maximum meter reading
Once I was going to Lahore from Islamabad, a Coure passed me very rashly, I started to chase him but failed to catch that car, then I converted the car on petrol, but still no speed gain:(
Coure is still a better car in all aspects when compared with alto
