李克强促多证合一：一季度日增市场主体4万户
百度 也许在发动机加速的平顺性和声音方面不及之前大家早年熟悉的i-VT和上一代的地球梦自吸发动机，但是在小排量涡轮发动机普及的今天，这台SPORTTURBO发动机的整体表现还是能令人满意，不会让你有那种动力不够，开着着急的不适感；怎么说，同系列的发动机在整备质量1764公斤的上也用了，况且它还是功率稍小的240TURBO版本了！新车全系用的都是CVT变速器，得益于CVT的特殊结构，正常驾驶时是完全体验不到换挡的感觉的，顿挫更是无从谈起，但是如果你将油门踏板全部踩下，那么CVT变速器还会模拟出自动变速器的升挡动作，这种模拟出的顿挫一定会还要多适应一下；CVT变速器省油、平顺优点是有了，但是要体验极限驾驶，体验更高驾驶感觉如何呢？答案是千万不要太较真了，因为这套动力系统会尽量使用较高的转速来营造敏捷的驾驶感受，虽然它确实这么做了，日常的行驶中稍微深踩油门，转速就会瞬间突破2500转，持续在一个较高转速很长时间，这除了会带来了扰人的发动机噪音外，不积极的降挡、没有手动拨片的辅助也是一个问题；但说回来了，新车的本质不是用来飚的，在城市里和高速以一个正常的方式去驾驶，已经能胜任了！说完了变化最大的动力系统，这回可以说说新车的操控到底和9代车型的区别了；首先是新车的转向系统，它用的是ESP双小齿轮式可变速比电动助力转向系统，说了那么长的名字可能一般人不知道什么意思，白话解释就是它可以提供更出色的转向感觉和更出色的动态性能；用句俗话说就是它的指向更精准，操控性更好，同时在转向的力度上，也会更适中，这与上代车型，设定价位轻柔的设定电子转向，不犀利和清晰为特点的操控大为不同；新车高速变向、过弯时的反馈很精准，没有一丝拖泥带水的感觉，让我有种驾驶着一款运动轿跑的错觉。
