NEW YORK (Kyodo) Toyota Motor Corp.'s new car sales in the United States posted a single-digit percentage increase in the first half of 2010 following a series of recalls, a U.S. research firm said Thursday.

Overall new car sales in the U.S. market for the same period rose 16.7 percent year-on-year, with other major carmakers enjoying double-digit growth, according to Autodata Corp.

Sales by all automakers operating in the United States totaled 5.614 million units in the January-June period, showing a steady upturn from the global auto recession last year against the backdrop of the U.S. economic recovery.

In the six-month period, sales by Toyota grew 9.9 percent from a year earlier to 846,542 units, marking the only single-digit growth among major U.S., Japanese and South Korean carmakers.
