在众多车辆评测选题中,类似“10-15万家用车怎么选?“一直都是最火热的话题之一。这个区间价位更接地气,更贴近老百姓的生活。那么,一台家用车应该具备哪些条件才算物有所值呢?笔者多年来咨询不下百位实际车主,95%以上的家庭更加注重”坐着舒服、“能装东西”、”省钱“、”别老坏“。反而对键盘车手所关心的”操控“、”强劲动力“没有过多需求,因为日常驾驶或许没有多少机会油门到底,也更没机会绕桩等极限驾驶情况。
本次我们挑选轩逸和雷凌作为对比也是基于大空间、不爱坏、省油等特点,真切回归到实际用车环境。在上一篇内容中(点击回看轩逸/雷凌静态对比)我们对比了两台车的空间、储物、外观等方面,轩逸座椅除了舒适以外,后排空间也更适合腿脚不便的老人,车内储物空间也更大更丰富。雷凌屏幕尺寸很大,科技感比较优秀。本篇,我们就实际生活用车场景,分享两台车在加速平顺性、噪音、乘坐感受等方面的感受。
刨根问底两车“基因强大”
轩逸→日产CMF平台 此平台非彼平台
雷凌→丰田TNGA平台 “去日近美
看车先探底,轩逸来自日产CMF平台,雷凌来自丰田TNGA平台。二位师出名门,基因都很强大。CMF是“此平台非彼平台”,它的平台模块十分丰富,根据不同车型配备不同”菜单“,同平台下,轿车和掀背车为相同配菜,而SUV和MPV车型又使用不同的配菜。另外,在同配菜下根据车身大小,又分出不同菜单。所以CMF是一套很复杂的平台系统。前期开发成本比较高。或许有些人高调喊出,认为CMF平台使用了很长时间并没有改变,但如果您站在产品战略和开发角度看,这说明CMF平台在很早以前就拥有长远策略,如今依然能够满足全球化安全碰撞标准以及耐久考验。
TNGA是丰田目前主打的平台架构,也是“去日近美”的一套架构。(词语解释:去日近美=车身结构、防护去掉原有的日系设计风格,而更加贴近美系车型,而且在部分结构铝合金轻量化使用方面也是如此。笔者在车展进行高端采访时,也咨询过丰田日方高端这个话题,丰田认为全球化设计是目前和未来的发展方向,设计不断迭代更新,对不同车系车型取长补短,相互借鉴。所以我们也可以把TNGA架构看做目前丰田全球化架构。
加速舒适性一:“芯”不同 “驾”不同
轩逸→线性输出是王道
雷凌→追寻一时之爽快
对于家用车来说,车辆设计初衷以及实际用车环境角度,应该以加速平顺和省油为主要目标。两车“芯”不同所以驾驶性格必然不同。轩逸搭载1.6升自然吸气发动机,雷凌为1.2T涡轮增压发动机。省油是它们的共同点,而不同点就是输出线性。从技术层面简单理解,自然吸气发动机动力输出比涡轮更加平顺。虽然现在小排量涡轮都使用上了“小惯量”、“轻量化叶轮”设计,尽量降低涡轮介入转速,使其增压更早,加速更平顺。但依然与自然吸气发动机有一定差距,油门踩得越深,加速越急,涡轮所介入的加速顿挫感也就更明显。而这种突如其来的加速感对乘坐感受并不友好。
平顺舒适性二:“箱” 同 “脾气” 不同
轩逸→温柔、激烈加速均可平顺输出
雷凌→温柔加速平顺、急加速顿挫
CVT变速箱应该是在所有变速箱种类当中最温柔,最平顺的。虽然轩逸和雷凌都搭载CVT变速箱,但它们的性格秉性并不相同。笔者特意在缓慢加速和油门到底急加速两种方式测试。轩逸在ECO模式、缓慢加速模式以及急加速模式下,加速平顺性优秀,全程没有感觉任何换挡顿挫。
雷凌在缓慢加速和急加速时表现出两种不同的脾气。缓慢加速平顺优雅,但在急加速时略显急促,80公里/小时以及100公里/小时两个速度下,变速箱会感觉明显顿挫。笔者分别坐在前排、后排以乘员角度感受,其加速平顺性均不太理想。由于CVT变速箱内部没有齿轮结构,所以顿挫感是由软件调整所带来的。在紧加速驾驶环境下的换挡逻辑和衔接还有一定优化空间。
乘坐舒适性三:“软”与“硬”“过滤”与“直接”
轩逸→温柔、激烈加速均可平顺输出
雷凌→温柔加速平顺、急加速顿挫
车是给人坐的,所以坐着舒服是舒适性的一项重要指标。车辆在复杂路面中行驶,保持舒适的坐姿并不容易,与其相关的车身、悬挂调校方式、座椅舒适性(人体工程学)、轮胎的选用等多方面因素有关。在相同路面条件下体验两台车,却给我们完全不同的乘坐体验。
整体偏软的悬挂加上柔软的全贴合座椅,造就轩逸有着优秀的乘坐舒适感。车辆行驶在柏油路、铺装路面时候轮胎和悬挂过滤掉大幅震动,最后再由座椅过滤其余细微震动。真正传入臀部、腰部的抖动微乎其微。如果将轮胎、悬挂以及座椅按照舒适性贡献划分,那么他们的比例大概为10%:50%;40%。
相比轩逸,雷凌悬挂调校偏向运动,座椅侧向支撑性也优于轩逸,但坐垫和靠背海绵偏硬,长时间乘坐容易出现疲劳现象。如果将雷凌的悬挂弹簧硬度降低并且在不改变侧向支撑,提升坐垫软度。或许乘坐舒适性能够得到明显提升。
静音舒适性四:“安静”与“吵闹”轩逸→隔音/轮胎双重贡献
雷凌→噪音明显 轮胎选择是重点
影响车辆行驶噪音,由发动机噪声、全车隔音、胎噪、风噪所决定。简单的说,就是坐在车内耳朵所听到的声音大小。为了直观展示,我们用测量数据方式对轩逸和雷凌在怠速(发动机运转,挂入P档,门窗、空调关闭、安静的环境下测试)、40公里/小时、60公里/小时、80公里/小时和100公里/小时速度下,以居中测量方式收集噪声数据。数据越小,说明车内声音越小,越安静。从下列表格中不难看出,轩逸和雷凌在怠速状态下,雷凌稍好,两车相差0.1分贝,听觉上几乎可以忽略。其余行驶速度下,轩逸表现都很优秀。直观听觉也是轩逸更为安静。
怠速数据相同,行驶噪音表现差,基本可以认定是轮胎的因素较大。如果,雷凌选用静音性更好、橡胶更软的轮胎或许静音性还可以进一步提升。单纯从两台量产车静音表现来看,轩逸车内噪音低,更适合家用车选择。
总结:
本次测试主要围绕95%以上用户的使用环境和需求,放弃常规的加速、绕桩测试等项目。着重介绍乘坐舒适性、加速平顺性以及隔音密闭性方面表现。虽然轩逸和雷凌都是主打家庭用车,但是它们性格迥异,在同等环境下体验,轩逸加速更平顺(雷凌涡轮和CVT都有顿挫点)、行驶噪音更小(雷凌胎噪相对较大)、座椅更柔软更舒适(雷凌座椅侧向支撑性好但不够柔软)。综合家用乘坐特点,笔者认为轩逸更适合“上有老、下有小”的家庭用车,相比年轻人,他们更需要一台加速平顺、乘坐舒适且安静的车。
