<p style="text-align: center;"><img src="http://www.autoju.com/wp-content/uploads/2017/06/95011497943626.jpg" style="float:none;" title="F1.jpg"/></p>

<p style="margin-top: 0px; margin-bottom: 0px; padding: 0px; max-width: 100%; clear: both; min-height: 1em; color: rgb(62, 62, 62); font-family: &#39;Hiragino Sans GB&#39;, &#39;Microsoft YaHei&#39;, Arial, sans-serif; line-height: 25.6px; white-space: normal; text-align: center; box-sizing: border-box !important; word-wrap: break-word !important; background-color: rgb(255, 255, 255);"><span style="margin: 0px; padding: 0px; max-width: 100%; color: rgb(127, 127, 127); font-family: 微软雅黑; font-size: 14px; white-space: pre-wrap; -webkit-text-stroke-color: rgb(0, 0, 0); box-sizing: border-box !important; word-wrap: break-word !important;">▲同样的车型，会显示出不同的油耗</span></p>
<p style="margin-top: 0px; margin-bottom: 0px; padding: 0px; max-width: 100%; clear: both; min-height: 1em; color: rgb(62, 62, 62); font-family: &#39;Hiragino Sans GB&#39;, &#39;Microsoft YaHei&#39;, Arial, sans-serif; line-height: 25.6px; white-space: normal; box-sizing: border-box !important; word-wrap: break-word !important; text-align: left; background-color: rgb(255, 255, 255);">现在很多车的仪表盘上有油耗显示，于是经常有人会晒油耗，同一台车，百公里10升是它，百公里5升也是它——没错，在不同状态下，车子的油耗差别就是这么大。油耗的差别，跟很多因素有关，但最主要的是跟速度有关，每台车都有“经济时速”，按经济时速跑，就可以保持比较低的油耗。</p>
<p style="margin-top: 0px; margin-bottom: 0px; padding: 0px; max-width: 100%; clear: both; min-height: 1em; color: rgb(62, 62, 62); font-family: &#39;Hiragino Sans GB&#39;, &#39;Microsoft YaHei&#39;, Arial, sans-serif; line-height: 25.6px; white-space: normal; box-sizing: border-box !important; word-wrap: break-word !important; text-align: left; background-color: rgb(255, 255, 255);">什么速度最省油？这方面的研究成果挺多，加拿大自然资源部（Natural Resources Canada）官网上有一个说明简单明了，先引用一下。</p>
<p style="margin-top: 0px; margin-bottom: 0px; padding: 0px; max-width: 100%; clear: both; min-height: 1em; color: rgb(62, 62, 62); font-family: &#39;Hiragino Sans GB&#39;, &#39;Microsoft YaHei&#39;, Arial, sans-serif; line-height: 25.6px; white-space: normal; box-sizing: border-box !important; word-wrap: break-word !important; text-align: left; background-color: rgb(255, 255, 255);">这个网站在推荐开车节油的办法时，强调了一点，就是“避免高速行驶”。文中说，<span style="margin: 0px; padding: 0px; max-width: 100%; box-sizing: border-box !important; word-wrap: break-word !important; color: rgb(2, 30, 170);"><strong style="margin: 0px; padding: 0px; max-width: 100%; box-sizing: border-box !important; word-wrap: break-word !important;">对于大部分轿车、SUV、皮卡来说，最省油的速度区间是“时速50公里到80公里之间”。</strong></span>如果超过“经济速度”，汽车的油耗会明显上升，在时速120公里的时候，汽车的油耗会比时速100公里时，大约增加20%。</p>
<p style="text-align:center"><img src="http://www.autoju.com/wp-content/uploads/2017/06/20831497943627.jpg" title="F3.jpg" style="white-space: normal; float: none;"/></p>
<p style="margin-top: 0px; margin-bottom: 0px; padding: 0px; max-width: 100%; clear: both; min-height: 1em; color: rgb(62, 62, 62); font-family: &#39;Hiragino Sans GB&#39;, &#39;Microsoft YaHei&#39;, Arial, sans-serif; line-height: 25.6px; white-space: normal; text-align: center; box-sizing: border-box !important; word-wrap: break-word !important; background-color: rgb(255, 255, 255);"><span style="margin: 0px; padding: 0px; max-width: 100%; color: rgb(127, 127, 127); font-family: 微软雅黑; font-size: 14px; white-space: pre-wrap; -webkit-text-stroke-color: rgb(0, 0, 0); box-sizing: border-box !important; word-wrap: break-word !important;">▲时速50公里到80公里，是油耗的“sweet spot”（来源于加拿大自然资源部网站）</span></p>
<p style="margin-top: 0px; margin-bottom: 0px; padding: 0px; max-width: 100%; clear: both; min-height: 1em; color: rgb(62, 62, 62); font-family: &#39;Hiragino Sans GB&#39;, &#39;Microsoft YaHei&#39;, Arial, sans-serif; line-height: 25.6px; white-space: normal; box-sizing: border-box !important; word-wrap: break-word !important; text-align: left; background-color: rgb(255, 255, 255);">这个说法跟美国能源部的有共同之处。美国能源部网站上说，尽管各种车最省油的速度区间不太一样，但<span style="margin: 0px; padding: 0px; max-width: 100%; box-sizing: border-box !important; word-wrap: break-word !important; color: rgb(2, 30, 170);"><strong style="margin: 0px; padding: 0px; max-width: 100%; box-sizing: border-box !important; word-wrap: break-word !important;">通常时速到50英里（约80公里）以上时，油耗会迅速上升。</strong></span></p>
<p style="margin-top: 0px; margin-bottom: 0px; padding: 0px; max-width: 100%; clear: both; min-height: 1em; color: rgb(62, 62, 62); font-family: &#39;Hiragino Sans GB&#39;, &#39;Microsoft YaHei&#39;, Arial, sans-serif; line-height: 25.6px; white-space: normal; box-sizing: border-box !important; word-wrap: break-word !important; text-align: left; background-color: rgb(255, 255, 255);">在高速行驶时，汽车的耗油量为什么会显著增加？这主要是两方面的原因：</p>
<p style="margin-top: 0px; margin-bottom: 0px; padding: 0px; max-width: 100%; clear: both; min-height: 1em; color: rgb(62, 62, 62); font-family: &#39;Hiragino Sans GB&#39;, &#39;Microsoft YaHei&#39;, Arial, sans-serif; line-height: 25.6px; white-space: normal; box-sizing: border-box !important; word-wrap: break-word !important; text-align: left; background-color: rgb(255, 255, 255);">首先，是风阻的影响。车速越高，汽车行驶需要克服的空气阻力越大，汽车高速行驶时，输出动力中用于克服风阻的部分最多能到40%左右。而且，随着速度的提高，空气阻力的增加速度也在加快。</p>

<p style="margin-top: 0px; margin-bottom: 0px; padding: 0px; max-width: 100%; clear: both; min-height: 1em; color: rgb(62, 62, 62); font-family: &#39;Hiragino Sans GB&#39;, &#39;Microsoft YaHei&#39;, Arial, sans-serif; line-height: 25.6px; white-space: normal; box-sizing: border-box !important; word-wrap: break-word !important; text-align: left; background-color: rgb(255, 255, 255);">在各种驾驶行为中，合理控制车速对油耗的影响不是最大的，你肯定想不到，影响最大的是“攻击性驾驶（Aggressive driving&nbsp;）”。美国人所谓的“Aggressive driving&nbsp;”，指的就是超速、急加速、急刹车、乱变道之类的“不文明”驾驶行为，以我之见，有这种毛病的中国人比美国更多。</p>
