Here's why and what you can do about it. "Winter is coming." We all know the mantra, but aside from the Game of Thrones implications, there are real-world declines in fuel economy associated with cold temperatures. Here is a quick list of the main reasons why many drivers see a drop in miles per gallon as the temperature does. Your Tires Are Underinflated Your car's tires will see a decline in pressure as the temperature drops. In the real world, you will see a decline of about 1 psi per 10 degrees F of temperature drop. The air isn't leaking out, it is simply following the laws of physics. PV=nRT is the formula any engineering student learns. And no, using nitrogen instead of air (which is about 80% nitrogen anyway) won't do a darn thing about it for two reasons. First of all, everything you read about nitrogen for tires is baloney and a scientist named Boyle figured out that all gases expand (or contract) at the same rate [ https://www.grc.nasa.gov/www/k-12/airplane/boyle.html ] back before the internet. Add pressure to your tires when they are at their coldest. The proper inflation pressure is on the door jam on the driver's side. By the way, this increased rolling resistance and reduction in efficiency strikes electric vehicles just as hard as internal combustion engine (ICE) powered cars. [ot] The Fuel You Use Changes Your gasoline is not the same fluid in winter as it is in winter. If you live where the temperature drops seasonally, your fuel suppliers will change the composition of the fuel they supply. They do this for drivability and also emissions reasons. There's not much you can do about this one. The EPA says that winter grades have less energy per unit volume than summer blends [ http://newsroom.aaa.com/2013/06/what-is-the-difference-between-summer-and-winter-blend-gasoline/ ]. Your Charging System Is Working Harder In Winter Batteries are not fond of cold weather. They require more energy to stay charged and that means your alternator is going to work harder and use more fuel. Hybrids and electric vehicles also see the effects of temperature on batteries. Cold Air Has More Resistance Highway driving is impacted by colder temperatures. Colder air is denser and offers more aerodynamic resistance. This affects electric vehicles as much as ICE vehicles. Your Heating System Uses Energy This reason for a decline in fuel economy is only relative to mild temperatures. Using the heating fan, defrosters, and heated seats make your car work a bit harder consuming more fuel. Not as much as running the AC does, but more so than in spring and fall temperatures. Electric vehicles are impacted more than ICE cars in this regard. Bundle up to save energy ...
