Honda Motor Co. may bolster its production capacity for sport utility vehicles in North America in anticipation of growing demand, a senior Honda executive said Wednesday.

Honda Vice President Koichi Amemiya told a group of stock analysts in New York that Honda is weighing its options and may come up with a decision in six months.

Amemiya said the options include expanding the existing production facilities or building a new plant.

Honda currently has four car assembly plants in North America, able to roll out 1.22 million units a year.

Honda saw an 11.2 percent jump in sales of sport utility vehicles and minivans in the U.S. last year, with sales soaring 27.1 percent in the first four months of this year.

Overall, the sales of Honda cars in the U.S. market rose 4.2 percent last year to 1.28 million units.

NSX-R price tag soars

Honda Motor Co. said Thursday it will add a new model to its NSX series of sports cars at a price of 11.95 million yen, making it the most expensive car made in Japan.

The two-seat NSX-R will go on sale Friday, Honda said, adding it hopes to achieve an annual sales target of 60 units.

The NSX-R, a new version of the NSX-R sold between 1992 and 1994, comes with a 3.2-liter engine and a six-speed manual transmission.

Honda launched the NSX in 1990 and has sold 7,100 units.
