<p style="margin-top: 0px; margin-bottom: 0px; padding: 0px; max-width: 100%; clear: both; min-height: 1em; white-space: pre-wrap; color: rgb(62, 62, 62); font-family: &#39;Helvetica Neue&#39;, Helvetica, &#39;Hiragino Sans GB&#39;, &#39;Microsoft YaHei&#39;, Arial, sans-serif; line-height: normal; 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%; line-height: 25.6px; font-size: 16px; font-family: 微软雅黑, &#39;Microsoft YaHei&#39;; box-sizing: border-box !important; word-wrap: break-word !important;">常见汽车工业焊接工艺主要是电阻焊和激光焊接。前者是将被焊工件在阴阳两极之间压紧，通电后电流经过工件接触面和临近区域，通过电阻热效应，将该区域加热融化或至塑性状态，从而使得金属结合。而激光焊接则用聚焦的激光束轰击焊件接缝，将光能转化为热能，实现融化-焊接的目的。</span></p>

		<title>时髦or实用，买车一定要选新技术吗？丨聚论</title>

				<description><![CDATA[<p style="text-align: left; line-height: 1.75em;"><span style="font-family: 微软雅黑, &#39;Microsoft YaHei&#39;;">【引言】衣不如新人不如旧，那么汽车技术是要追新，还是要从旧？</span></p>
<p style="text-align: left; line-height: 1.75em;"><span style="font-family: 微软雅黑, &#39;Microsoft YaHei&#39;;">过去和当下，我们都活在噱头里。“噱头”这个词，在厂商们的营销活动中，常被解读为“看点”和“卖点”。作为消费者的我们，并不太喜欢这个词汇，因为这个词的背后往往隐藏着“虚假”。</span></p>
<p style="text-align: left; line-height: 1.75em;"><span style="font-family: 微软雅黑, &#39;Microsoft YaHei&#39;;">“噱头”之所以会流行，有它的道理，只是这种道理更多体现在表象上罢了。这种“噱头”有可能是我们已经深入思维的“误区”，这种误区不仅普通消费者有，国家政策制定者也会有。</span></p>
<p style="text-align: left; line-height: 1.75em;"><span style="font-family: 微软雅黑, &#39;Microsoft YaHei&#39;;">我们在此前的四篇文章中，详细聊到了除涡轮增压外的其他节能减排技术。与涡轮增压不同的是，HCCI这种技术是在努力提高排量，而提高排量却往往得不到政策的垂青，比如最新一波的购置税减半。即便采用HCCI技术的发动机比采用涡轮增压发动机的排放更低，也无济于事。</span></p>
<p style="text-align: left; line-height: 1.75em;"><span style="font-family: 微软雅黑, &#39;Microsoft YaHei&#39;;">另外还有很多例子，比如我们采用欧洲的循环工况测试规则等，这些“误区政策”，我们将放在此技术系列的最后一篇（也就是下一篇）中具体阐述。今天，我们的重点是了解汽车的那些“误区技术”，并说一说大部分先进的技术对于普通消费者来说并无指导意义。</span></p>
<p style="text-align: left; line-height: 1.75em;"><strong><span style="font-family: 微软雅黑, &#39;Microsoft YaHei&#39;;">一、作为消费者，应该关注什么？</span></strong></p>
<p style="text-align: left; line-height: 1.75em;"><span style="font-family: 微软雅黑, &#39;Microsoft YaHei&#39;;">我们需要撇开以往所有的汽车知识，才能更容易理解这个问题。其实，我也是一个小白，对汽车只是略知皮毛，但这并不妨碍我评价一部车的具体表现。在我看来，那些包装过的汽车技术对于消费者而言并无太大的指导意义，反而可能会增加使用成本，我只关心这款车的性能、可靠性、使用成本和满意度。</span></p>
<p style="text-align: left; line-height: 1.75em;"><span style="font-family: 微软雅黑, &#39;Microsoft YaHei&#39;;"></span></p>
<p><img src="http://www.autoju.com/wp-content/uploads/2015/12/74461449712812.jpg" style="float:none;" title="e1.jpg"/></p>
<p style="text-align: left; line-height: 1.75em;"><span style="font-family: 微软雅黑, &#39;Microsoft YaHei&#39;;">媒体作为意见领袖，却传递给消费者很多错误的消费观念，比如追求更大的空间、追求更新的技术等。然而，这些其实已经超出很多普通消费者的认知范围。并非每个消费者都是汽车爱好者，大部分消费者在购车前只是登陆下网站，了解下价格，对技术一窍不通，所以媒体真正要传递的是这款车具体的表现。不需要拆发动机，也不需要解读变速箱。</span></p>
<p style="text-align: left; line-height: 1.75em;"><span style="font-family: 微软雅黑, &#39;Microsoft YaHei&#39;;">性能方面的使用感受，其实已经可以很明确地表现这款车在外观造型及空间上的取舍。动力上的优劣得失，乘坐感如何、舒适感如何、静音性如何，这些我们只是需要一个简单的评级。针对竞品，我们也需要进行这个简单的评级，看看所考虑车型的表现到底居于哪个层次，哪些方面应该看重，而哪些方面又不适合。</span></p>
<p style="text-align: left; line-height: 1.75em;"><span style="font-family: 微软雅黑, &#39;Microsoft YaHei&#39;;">可靠性参考的其实是质量稳定性。再好、再先进的技术如果通不过市场检验，也是毫无用处。上个世纪，汽车企业们研发技术远比我们现在激进。如今我们开展的新技术，几乎都可以在上个世纪发现端倪，比如此前我们解读的NB哄哄的HCCI技术。只是，故障频出，严重影响使用感受，这些技术也就偃旗息鼓了。</span></p>
<p style="text-align: left; line-height: 1.75em;"><span style="font-family: 微软雅黑, &#39;Microsoft YaHei&#39;;"><img src="http://www.autoju.com/wp-content/uploads/2015/12/84051449712812.jpg" title="e2.jpg" style="white-space: normal; float: none;"/></span></p>
<p style="text-align: left; line-height: 1.75em;"><span style="font-family: 微软雅黑, &#39;Microsoft YaHei&#39;;">使用成本是指我从买这款车开始要为它投入多少钱，5年内总花费多少，相比竞品有什么优势，是最不值还是最性价比，通过使用成本以及五年内总花费可以得出大概。</span></p>
<p style="text-align: left; line-height: 1.75em;"><span style="font-family: 微软雅黑, &#39;Microsoft YaHei&#39;;">至于满意度，其实就是在这款车陪伴你走过五六年之后，你准备更换座驾，你还会不会选择它的一个判断。或者说，你对这五年里它的表现打一个分数，如果大部分消费者都满意，那么我们可以断定这是一款好车。</span></p>
<p style="text-align: left; line-height: 1.75em;"><span style="font-family: 微软雅黑, &#39;Microsoft YaHei&#39;;">作为一个普通消费者，我们更应该在意的是汽车作为工具，它使用层面的表现。就像是汽车安全测试一样，它根本不在意你用了什么超强钢材，实验室只知道按照一定的速度、一定的角度碰撞，成绩好便是好，差便是差。这也正应了那句俗语：“金杯银杯不如老百姓口碑”。</span></p>
<p style="text-align: left; line-height: 1.75em;"><strong><span style="font-family: 微软雅黑, &#39;Microsoft YaHei&#39;;">二、本田地球梦科技，真的先进？</span></strong></p>
<p style="text-align: left; line-height: 1.75em;"><span style="font-family: 微软雅黑, &#39;Microsoft YaHei&#39;;">一提起本田，很多车迷会情不自禁的说道“本田大法好”，车聚也有很多同事是本田的死忠粉，我们刊登的文章也鲜有抹黑本田的先例，但这并不妨碍我们更加客观地评价它。一个品牌，有好有差，才更真实。</span></p>
<p style="text-align: left; line-height: 1.75em;"><span style="font-family: 微软雅黑, &#39;Microsoft YaHei&#39;;">“Earth Dreams Technology（地球梦科技）”是本田发布的全新一代动力总成，其宣传语是本田把低油耗高动力和驾驶乐趣完美融合的看家本领。国内率先搭载的地球梦引擎的车型为9代雅阁。</span></p>
<p style="text-align: left; line-height: 1.75em;"><img src="http://www.autoju.com/wp-content/uploads/2015/12/78651449712812.jpg" title="e3.jpg" style="white-space: normal; float: none;"/></p>
<p style="text-align: center; line-height: 1.75em;"><span style="font-family: 微软雅黑, &#39;Microsoft YaHei&#39;;">▲ 美版第九代雅阁</span></p>
<p style="text-align: left; line-height: 1.75em;"><span style="font-family: 微软雅黑, &#39;Microsoft YaHei&#39;;">雅阁在国内最大的竞争对手一直是丰田的主力车型——凯美瑞。八代雅阁在国内创造了惊人的销量，同样六代凯美瑞也战绩辉煌，两车势均力敌。只是，本田从大众身上学到，技术包装在国内十分有必要，因此本田推出了地球梦科技。</span></p>
<p style="text-align: left; line-height: 1.75em;"><span style="font-family: 微软雅黑, &#39;Microsoft YaHei&#39;;">现在的地球梦科技已经引起了很多消费者的注意，只要提到这个词，似乎就意味着“动力强劲、技术先进”，事实当真如此吗？从消费者的角度出发，搭载地球梦科技的本田雅阁的确称不上优势巨大。</span></p>
<p style="text-align: left; line-height: 1.75em;"><span style="font-family: 微软雅黑, &#39;Microsoft YaHei&#39;;">本田家族的当家明星是“i-VTEC”，地球梦科技里又引入了新的技术明星“缸内直喷”，这让人感觉这款发动机无论在动力还是经济性上一定表现十分优秀，但实际上K24发动机功率只有137kW，与使用“保守的”双VVT-i和多点电喷的丰田5AR-FE发动机动力几乎一样。</span></p>
<p style="text-align: left; line-height: 1.75em;"><span style="font-family: 微软雅黑, &#39;Microsoft YaHei&#39;;"><img src="http://www.autoju.com/wp-content/uploads/2015/12/69231449712812.jpg" title="e4.jpg" style="white-space: normal; float: none;"/></span></p>
<p style="text-align: left; line-height: 1.75em;"><span style="font-family: 微软雅黑, &#39;Microsoft YaHei&#39;;">虽然，根据美国《消费者报道》的数据，本田K24搭载CVT变速箱带来了巨大的经济性优势，百公里油耗比凯美瑞低1升左右，但其售后保养成本相比凯美瑞却毫无优势。5000公里/次的频率是凯美瑞10000公里/次的两倍，而且雅阁缸内直喷发动机需要频繁使用相应清洁剂，无形中增加了后期维护成本。</span></p>
<p style="text-align: left; line-height: 1.75em;"><span style="font-family: 微软雅黑, &#39;Microsoft YaHei&#39;;">另外一款备受好评的本田飞度同样如此。与丰田致炫竞争的飞度，不仅拥有动力上的绝对优势，L15B2发动机功率比致炫7NR-FE足足高出了17kw(24马力)，而且拥有变速箱上的优势，CVT变速箱比4AT看起来就高档许多。</span></p>
<p style="text-align: left; line-height: 1.75em;"><span style="font-family: 微软雅黑, &#39;Microsoft YaHei&#39;;">此处，我们暂且不谈档位是否代表性能的观点，单看动力，飞度已经超越了致炫。但随后同样的问题依然困扰着飞度的车主们（我也曾是飞度车主），相比老飞度，新飞度的保养周期为5000公里/次，每次需要添加喷油嘴清洗剂（140元），每次保养大致在492元左右，同样致炫的保养周期为10000公里/次，每次费用大致在376元左右。如果按照官方建议保养周期计算，6万公里飞度需花费7280元，而致炫仅需3219元。</span></p>
<p style="text-align: left; line-height: 1.75em;"><span style="font-family: 微软雅黑, &#39;Microsoft YaHei&#39;;">讲那么多，其实就是说，本田“地球梦科技”并非全是优点，它是本田的目前主打的技术，地球梦是本田的营销概念。相比竞品，地球梦科技并非可以“秒天秒地秒一切”，其实它跟很多竞品采用的技术在同一级别上。</span></p>
<p style="text-align: left; line-height: 1.75em;"><strong><span style="font-family: 微软雅黑, &#39;Microsoft YaHei&#39;;">&nbsp;三、涡轮增压和双离合，曾是技术噱头</span></strong></p>
<p style="text-align: left; line-height: 1.75em;"><span style="font-family: 微软雅黑, &#39;Microsoft YaHei&#39;;">随着越来越多的科普文章出来，以及双离合大规模爆出质量危机，人们已经开始对涡轮增压和双离合有了清醒的认知。越来越多的消费者意识到，原来涡轮增压只是一种应对排放法规或者企业走向的技术，与自然吸气相比，并非神一般的存在。</span></p>
<p style="text-align: left; line-height: 1.75em;"><span style="font-family: 微软雅黑, &#39;Microsoft YaHei&#39;;"><img src="http://www.autoju.com/wp-content/uploads/2015/12/28301449712813.jpg" title="e5.jpg" style="white-space: normal; float: none;"/></span></p>
<p style="text-align: left; line-height: 1.75em;"><span style="font-family: 微软雅黑, &#39;Microsoft YaHei&#39;;">真正让我们意识到涡轮增压和双离合并非先进的一个现象是，越来越多的数据表明，涡轮增压并不省油，双离合也存在这样那样的问题。揭破这些真相的恰恰是普通消费者的直接使用感受。</span></p>
<p style="text-align: left; line-height: 1.75em;"><span style="font-family: 微软雅黑, &#39;Microsoft YaHei&#39;;">最早享受技术红利的企业是大众汽车。北京奥运会之后，大众开始将涡轮增压技术TSI以及DSG双离合技术包装过后，以“黄金搭档”组合的方式投入了大量的人力物力宣传推广。</span></p>
<p style="text-align: left; line-height: 1.75em;"><span style="font-family: 微软雅黑, &#39;Microsoft YaHei&#39;;">大众通过小排量增加涡轮的方式（TSI），一方面宣传小排量的燃油经济性，同时加大了旗下主力技术缸内直喷的强调，另一方面宣传涡轮增压的动力更加强劲，而且在较低的转速区间即可保持最大扭矩输出，动力输出持续饱满。TSI发动机当时不仅被媒体，也被消费者认为是先进的代表，正引领着未来发动机小型化的趋势。随后，搭载1.4T发动机、1.8T发动机、2.0T发动机的大众车型销量持续高涨。</span></p>
<p style="text-align: left; line-height: 1.75em;"><span style="font-family: 微软雅黑, &#39;Microsoft YaHei&#39;;"><img src="http://www.autoju.com/wp-content/uploads/2015/12/34431449712813.jpg" title="e6.jpg" style="white-space: normal; float: none;"/></span></p>
<p style="text-align: left; line-height: 1.75em;"><span style="font-family: 微软雅黑, &#39;Microsoft YaHei&#39;;">在大众所强调的黄金动力组合上，DSG双离合变速箱也扮演着极为重要的角色。大众在对其的宣传主要集中在运动性上，将DSG与赛车运动联系起来，这样就可以传递给消费者DSG性能优越的印象。实际上DSG最起初的卖点是换挡极快，而且经济性出色。双离合相当于两组手动变速箱进行配合，配备此变速箱的车型，理论上动力传输不会中断，同时由于没有采用液力变矩器，传递效率更高。</span></p>
<p style="text-align: left; line-height: 1.75em;"><span style="font-family: 微软雅黑, &#39;Microsoft YaHei&#39;;">然而这些先进技术的背后，却隐藏着各种质量隐患。在大众推出“黄金搭档”没多久，中央电视台就找上了门，相继爆出大众TSI发动机熄火门、故障门等质量问题，同时DSG也相继爆出“死亡闪烁”，主要表现在换档有异响，换挡顿挫、转速突然升高，有时只能在奇数档使用，最严重的是所有档位灯不停闪烁，导致无法换挡、失去动力、熄火等问题。</span></p>
<p style="text-align: left; line-height: 1.75em;"><img src="http://www.autoju.com/wp-content/uploads/2015/12/26151449712814.jpg" title="e7.jpg" style="white-space: normal; float: none;"/></p>
<p style="text-align: left; line-height: 1.75em;"><span style="font-family: 微软雅黑, &#39;Microsoft YaHei&#39;;">当时，大众TSI+DSG爆出的质量问题几乎无解，即便更换新的DSG依然不能彻底解决问题。大众此时只得给出延保的解决方案，将2万6万公里延长到了4年15万公里，维持到此批次产品报废。</span></p>
<p style="text-align: left; line-height: 1.75em;"><span style="font-family: 微软雅黑, &#39;Microsoft YaHei&#39;;">然而，就是在这种情况下，人们依然对大众充满了信任。在中央电视台曝光大众出现大规模质量问题之后，人们的反应是“因为这个技术比较先进”。一语成谶，先进的大众，最终变的不“先进”了。</span></p>
<p style="text-align: left; line-height: 1.75em;"><span style="font-family: 微软雅黑, &#39;Microsoft YaHei&#39;;">其实，涡轮增压和双离合在可靠性以及使用成本，甚至消费者满意度上均没有表现出太大的优势。只是，当我们意识到这一点时，时间已经过去五六年之久，这些时间，正好是考验我们消费者汽车认识的一段时间。</span></p>
<p style="text-align: left; line-height: 1.75em;"><strong><span style="font-family: 微软雅黑, &#39;Microsoft YaHei&#39;;">车聚小结：</span></strong></p>
<p style="text-align: left; line-height: 1.75em;"><span style="font-family: 微软雅黑, &#39;Microsoft YaHei&#39;;">总而言之，技术并不应该成为左右消费者购车的一个根本因素。因为，我们很难分清，这项技术在不远的未来到底是好是坏，毕竟可靠性的数据报告都来自那些敢于吃螃蟹的人。作为消费者，我们注重这款车在日常使用中的整体表现即可，就像挨踢界说的那样“忘记参数”。</span></p>
<p style="text-align: left; line-height: 1.75em;"><span style="font-family: 微软雅黑, &#39;Microsoft YaHei&#39;;">可是，如果只是消费者被噱头误导也就算了，但如果政策制定者也被误导，那可能就是件麻烦事儿了，我们下篇文章见吧！</span></p>
