Whether broken out by makes or by segment, market share has rollercoastered inside a narrow band from 10.5 to 11.5 percent since "at least" 2008. Closer investigation reveals the shifting boundaries in the aspirational pond, with brands like Mercedes-Benz and Audi gaining territory as Lexus and Lincoln lost it, and Saab and Hummer were buried, dead, under it. One neat note is that Tesla has gone from a share of zip to .12 percent.
The subcompact and compact crossover segments show growth, with those little high-riders jumping from .3 percent to 1.16 percent of overall industry sales. Their rise, though, is concomitant with the decline of four other segments: compact and midsize cars and fullsize cars and SUVs. We think the next few years that will tell if the small-car expansion can overcome the large-car retraction, with a phalanx of smaller offerings like the CLA only recently hitting the market and others like the GLA, Macan and Q1 doing so in the near future.
