The big success of these four is the VW group, whose world market share has gone up each of these years, going from 8.3% to 10.3%. GM has slipped from 14.5% to 10.9%
The next four are as follows:
For these, the Hyundai Group has moved four places and now rivals Ford for fourth spot. Its share has improved from 4.6% to 7.7%. Honda slumped badly in '09 and the trend continues for '10.
2010 will see improvement for the majority of brands featured here. The most impressive companies for the 2005-10 period are VW & Hyundai and they will continue to do well.
GM is the big loser, but the worst is over for the General. Toyota grew so quickly (too much so) until '07 and then fell away suddenly, a mistake it now acknowledges. Expect Honda to slip in '10, as it seems to be steadfastly refusing to prop up sales with sharp pricing.
The bottom line: 2010 will be better, but overall things aren't that good.
