丰田也有CVT, 1.5年前我试车时用过. 倒是发明者欧洲人造汽车不像日产, 丰田, Honda.......对cvt感兴趣

CVT的优点是省油, 排放低(欧洲有很高的标准, 阻挡了一些车进入欧洲市场), 平顺, 制造成本低, 但修理成本高, 1般是整个换, 听说$5,000usd以上. 也不宜‘吃苦耐劳’ 如: 载荷重/越野。

用户对2010.前出产CVT反馈差(新产品， 技术不成熟), 为挽回市场, 日产等公司除对产品作了些技术改进外, 还对CVT extended warranty.

Q2. 
What are the new terms of the extended warranty?
A.    
To provide customers with additional assurance regarding their overall cost of ownership we have doubled the warranty period for the transmission in all Model Year 2003 to 2010 Nissan models with a CVT. The existing powertrain warranty coverage of 5 years/60,000 miles will be extended at no cost, for CVT repairs, replacements or related towing, to 10 years/120,000 miles, whichever comes first.
