Honda assembled more vehicles in the United States than it did in Japan during the April-June quarter.
It is the first time in the company’s history that Honda's US production has exceeded Japan’s for an entire quarter.
US output for the quarter was 236,819 vehicles compared with 236,559 produced in Japan. In all of North America, Honda produced 322,260 vehicles. US production is still 11,000 vehicles behind Japan's total for the year to date, however.
The proportion of Honda vehicles sold in the US that are produced in North America reached 90 per cent in the first six months of 2010.
