Although Toyota Motor Corp. (NYSE: TM) has bypassed the now-out-of-bankruptcy General Motors as the largest automaker in the world, many of its cars in the U.S. market are, well, boring. It's true that fuel efficiency is now top-of-mind on the U.S. auto buyer's agenda, but the love for fast sports cars has never gone away. It's just been suppressed.

The new Camaro from GM is proof -- it's affordable, sexy, and a true sports car in its modern glory. It is amazing what having a desirable car can do for an automaker's image, even though one car does not make a company (far from it).

Toyota Motor Corporation (NYSE: TM) indicated today that it will create two separate marketing companies to ensure the world knows even more about the cars and trucks it produces. One of the companies will focus on the U.S. market, while the other will look at the global arena outside the U.S. Both companies will light up operations at the first of next year, but possibly by the end of this year.

Toyota (NYSE: TM) is the world's most successful car company, even after a bad year in which the global recession hammered it business. By most calculations, it is the world's largest auto company. It has a market cap of $100 billion even with its stock down 40% from its 52-week high. GM's (NYSE: GM) has been below $3 billion recently.

All three of the U.S. car companies have the same CEO that it did a year ago. After turning in remarkably poor results based, to some extent, on poor product plans, none of the chief executives has paid for it.

Toyota is about to replace its CEO. According to The Wall Street Journal (subscription required), "Toyota Motor Corp.'s senior board members have selected Akio Toyoda, grandson of the company's founder, to head the company as its next president." Toyota's current presided, Katsuaki Watanabe, will stay with the company, but has been kicked upstairs.

Toyota has been the world's leading car company in innovation and efficient manufacturing, and it has been widely imitated. Perhaps its attitude toward management should be imitated as well. Poor results cause management change. The message has not made it from Tokyo to Detroit.
