The folks in Detroit may be pleased to see Toyota Motor Corp. (NYSE: TM) cutting its sales forecasts, but the pleasure is sure to be short lived. Despite its more modest outlook, Toyota leads General Motors (NYSE: GM) in global vehicle sales -- and its lead is only getting bigger.

According to a report on Reuters, GM sold 4.54 million vehicles worldwide in the first two quarters of 2008. This represents a 3% drop from the same period last year. Although sales in Europe, Latin America and Asia actually rose, the General couldn't overcome a whopping 15% decline in North America.

Toyota, on the other hand, saw a 2.2% increase in global sales, to 4.8 million units. This gives Toyota a lead in the range of a quarter million vehicles or more. And with its global sales growing, the lead is likely to widen, especially as Toyota switches over to producing more efficient cars in North America and fewer of the wasteful trucks that Americans loved so much until just a few weeks ago.

As Autoblog points out, the sales crown is important to both companies, although neither will admit it publicly. GM was the global sales king for 77 years, and the loss of that title will certainly hurt. Last year, the sales race ended essentially in a tie. But with these results, it looks like Toyota will be the champ in 2008 and, in all likelihood, beyond.
