Q. Which is better, petrol or diesel and automatoic or manual - Swift?

All over swift disel is best if your use is daily and long routes, in priceing you will have to pay more compare to petrol,in return you gets power with outstanding performance, and nowadays automatic cars have been successfully running, in bumper to bumper traffic automatic cars are best. I would suggest you Mr. Vidya sagar go for swift Disel automatic variant, its best in class.

All are good,depends on individual choice and running... If you have a daily run of 100+kms then go for diesel or else go for petrol. Automatic or manual depends on traffic condition and your personal choice of driving.

Diesel is better in terms of less fuel consumption. It's best to take for long rides and long journies.
