As with this year's American football season, weekly surprises in the car industry are now standard fare. VW recently overtook Ford for the number three spot in global sales, and now the home of the Beetle and the Veyron has overtaken Toyota as the industry's most valuable company based on dollar-converted market capitalization. Just as eyebrow raising is the reason for it: Toyota's stock has dropped 5% to its lowest point in four years due to the usual suspects, while VW's stock has climbed a stratospheric 87% due to the fact that Porsche is busy gobbling up the company.
