"While Ford and Chevrolet continue their perennial fight for dominance in the U.S. car and truck market, Toyota has slipped in under the radar to claim the top spot as the best-selling automotive brand in America. The Japanese automaker is just too modest to mention it. Through May, Toyota Motor Corp. led all brands with U.S. unit sales of 954,000 vehicles, a razor-thin 5,200 units ahead of General Motors Corp.'s Chevy brand and 40,000 better than the Ford Motor Co.'s Ford brand," The Detroit News reports.
