This morning’s commute was very rewarding from a fuel economy standpoint.  I understand that cooler air produces more power, but cold air also increases all kinds of friction and resistances.  First there is air resistance, rolling resistance, internal friction in all the car’s systems, the battery performs less effectively and more.

With the warmer temperatures the battery comes to life and there is less dense air to push the car through and the rolling resistance of the tires decreases too.

I achieved 61.2 miles per gallon according to the car’s averaging fuel consumption display.  Not a terrible start to the weekend.  Bring on spring temperatures!

Don’t be shy, post a comment.
