Toyota Motor Corp. surpassed General Motors Corp. in quarterly sales for the first time, making it the world's biggest automaker. Toyota sold 2.348 million vehicles world-wide in the January to March period, topping the 2.26 million vehicles that GM sold in the same period. While these figures represent only quarterly results, analysts say it's only a matter of time before the Japanese automaker surpasses GM in its annual figures. GM has been the world's No. 1 automaker for more than 70 years.
