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(dòng)力。X1是在寶馬1系（上圖）的基礎(chǔ)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(jí)、E級(jí)和S級(jí)。這一點(diǎn)令人印象深刻，不過伯恩斯坦研究公司（Bernstein Research）的分析師們認(rèn)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(dòng)銷量，出臺(tái)各種激勵(lì)手段，而且開始依賴出租車公司等批量客戶。

優(yōu)勢方：寶馬

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.
