4.增長：增值車型

????寶馬X1等派生車型給寶馬的增長帶來了不小的推動力,。X1是在寶馬1系（上圖）的基礎上衍生出的一款跨界車,。梅塞德斯的增長則主要來自它的核心車型——C級、E級和S級,。這一點令人印象深刻,，不過伯恩斯坦研究公司（Bernstein Research）的分析師們認為，如此依賴核心車型,，表明了奔馳存在缺乏想象力的毛病,。這也迫使奔馳不得不花更大的力氣推動銷量，出臺各種激勵手段,，而且開始依賴出租車公司等批量客戶,。

4. Growth: Incremental Models

????BMW's growth has been driven by spinoff models like the X1 -- a crossover derivative of the popular 1-series (above). Mercedes gets its growth from its core models -- C-class, E-class, S-class. That's impressive, but analysts at Bernstein Research believe that focus shows a lack of imagination and has forced Mercedes to push sales harder with incentives and deliveries to fleets like taxi companies.
