Which car is efficient

Car a and Car b have same engines of same power but car a has smaller wheel as compared to that of b which one is efficent ???????

Re: Which car is efficient

Well that depends upon how you define "efficient".

Re: Which car is efficient

The one which has bigger tire is faster, and the one with smaller tire is more powerfull. By the way do you want to buy a car or this is a joke??

Always get the one with bigger tires!!

The spinning wheels store eenergy which will be dissapated upon breaking, so the smaller wheeled car would be more efficient in this regard.

Re: Which car is efficient

Your question can be read in two ways.

1. The same car has a choice of wheels.

2. There are different cars with different wheels.

Petroleum fuel engines have a RPM and torque load that produces peak efficiency. The wheel size and gearing ratio are selected to produce this operating point at standard road speeds.

Then there is the efficiency of the gear box and other items in the path from the engine to the wheels.

For maximum efficiency stay home or walk or use a bicycle.

THE CAR WITH SMALLER WHEEL WILL BE MORE EFFICIENT BECAUSE FRICTION WITH ROAD WILL BE MINIMUM

Which car is efficient

The smaller wheel will have to spin more-the engine will have to run at a higher RPM for the same vehicular speed. The engine will wear more..

The smaller wheel will have more leverage and the engine will won't have to supply as much horse power to start the car moving up to speed...

hhmmm... At highway speeds, get the larger wheel, for stop and go driving get the smaller wheel. You can just change wheels when you get to the on ramp.

Don't mind my perplexion, I'll be okay.
