5. 改名換姓

2006年，林肯推出了一款全新的名為“西風”（Zephyr）中型運動轎車，但2007年就把它的名字變成了MKZ。隨后除了林肯“領航員”（Navigator）外，林肯把所有車型都改成了以“MK”打頭的名字。

英菲尼迪現在采用的全新命名規則是，所有轎車和轎跑的前綴都是“Q”，所有酷越車和SUV的前綴都是“QX”。首款采用這個規則的車型將是即將上市的Q50，它將取代G系列的轎車。其他車型將在2014車型年采用新的命名規則，幾乎肯定會讓人犯迷糊。

優勢方：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???????
