Swift performance is optimum.The petrol engine is a natural aspirated petrol engine so obviously it wont have that kick but its not disappointing .But for 4.6 lakhs price swift petrol is one of the best car.
My swift petrol give 17.8 in city.Maruti is best. I am one among the 10 lacs satisfied customer of maruti swift.The unique design offers great stability and handling.
after taking subjesct of reselling no one can beat swift & swift generates 87bhp.
So recommend you go with swift
