Truck maker Isuzu Motor Ltd. said Tuesday it set all-time highs in group pretax and operating profit in fiscal 2005, thanks to robust sales in the United States and Southeast Asia.

The results mark three consecutive years of record profits for the truck maker.

Isuzu reported an operating profit of 90.66 billion yen, up 4 percent from the previous year, and a pretax profit of 93.84 billion yen, up 2.5 percent, on sales of 1.58 trillion yen.
