5. 改名换姓

2006年，林肯推出了一款全新的名为“西风”（Zephyr）中型运动轿车，但2007年就把它的名字变成了MKZ。随后除了林肯“领航员”（Navigator）外，林肯把所有车型都改成了以“MK”打头的名字。

英菲尼迪现在采用的全新命名规则是，所有轿车和轿跑的前缀都是“Q”，所有酷越车和SUV的前缀都是“QX”。首款采用这个规则的车型将是即将上市的Q50，它将取代G系列的轿车。其他车型将在2014车型年采用新的命名规则，几乎肯定会让人犯迷糊。

优势方：林肯  

5. Name change

In 2006, Lincoln introduced an all-new mid-size sport-sedan reviving the Zephyr nameplate, only to change its name to MKZ in 2007. Then it renamed all its vehicles, except the Lincoln Navigator, with letter names that began with "MK."

Infiniti is now using a new product nomenclature scheme where all sedans and coupes will carry a "Q" prefix, while all crossovers and SUVs will carry a "QX" prefix. The first model to follow this scheme will be the upcoming Q50, which replaces the G sedan. The rest of the line will be transitioned to the new scheme by the 2014 model year, and confusion will likely ensue.

Advantage: Lincoln
