There are a lot of reasons we use more fuel when it’s cold. It takes longer for cars to warm to their optimum temperature for fuel, for one. Plus, when we use heaters, seat warmers, and the defrost, it takes more energy, which uses up more fuel. Cold air also increases wind resistance, decreases tire pressure, and hurts your battery’s performance.
But there are plenty of easy things you can do to reverse some of these problems. Don’t warm up your car before you go somewhere—idling is the biggest waste of gas there is. If you have a garage, park inside it, so your car spends less time getting up to temperature. And check your tire pressure regularly! If they’re low, fill ‘em up.
We at Blackburn Nissan are proud to tell you that Nissan has dramatically improved its overall fuel efficiency for 2013. In fact, it has improved at a greater degree than any other US automaker. And, while it may not be on top, it’s getting very, very close. If it continues its healthy trend, that may happen soon.
The overall efficiency numbers are calculated by taking an average of a company’s entire product line. In 2012, Nissan’s average was 24.1 miles per gallon. After calculations had been completed and the smoke (or rather, emissions) had cleared, Nissan’s fuel efficiency numbers were 26.2 in 2013. That’s a whopping 2.1 increase!
Fuel efficiency can be improved a number of ways. Between 2012 and 2013, Nissan put its Altima line on a diet, cutting its weight by 80 lbs. That’s one way to help. Nashville Public Radio reported Pierre Loing, vice president of product planning at Nissan, as saying, “Achieving good fuel economy is not a miracle. You need to work on weight reduction, aerodynamics, frictions and powertrain.”
