DiGiovanni said GM remains hopeful the federal economic stimulus package will help sales in the second half of the year.
A 24 percent jump in sales for Ford's popular Edge crossover couldn't make up for falling sales of pickups and large SUVs. Ford's truck and SUV sales dropped 16 percent versus March 2007. Sales of the Ford Expedition SUV fell 34 percent, while sales of the perennially popular F-Series pickup -- which will be replaced with a new version this fall -- were down 24 percent.
Ford's car sales were down 10 percent, dragged by declining demand for the Ford Mustang and Crown Victoria sedan. Ford's overall sales for the first quarter were down 9 percent.
Toyota Motor, which beat Ford to become the No. 2 automaker by U.S. sales last year, held onto its lead in the first quarter, outselling Ford by more than 43,000 vehicles. But Toyota took a beating in March, reporting truck and SUV sales down 14 percent and car sales down 7 percent. The Tundra pickup saw a surprising 17 percent sales increase, but totals were dragged down by SUV sales, which fell 20 percent. Toyota's sales were down 6 percent for the quarter.
Honda Motor, which had bucked the downward sales trend in February, saw its 3 percent increase in car sales eroded by a 12 percent decline in truck and SUV sales. That drop was led by the Honda Pilot SUV, which saw sales fall 24 percent. Honda's sales were flat for the first quarter.
Truck sales have been hurt by the slowdown in housing construction. Small cars fared best as consumers focused on fuel efficiency. The Ford Focus saw sales jump 24 percent for the month, while Toyota's subcompact Yaris saw sales rise 83 percent and Honda's subcompact Fit saw a 74 percent jump.
GM shares were up 66 cents, or 3.5 percent, to $19.71 in afternoon trading. Ford shares rose 12 cents to $5.84, Toyota's U.S. shares rose $2.22 to $103.11 and Honda's U.S. hares were up $1 to $29.81. Auto shares rallied along with the market amid optimism that the worst of the credit crisis has passed and that the economy is faring better than expected.
The Associated Press reports unadjusted figures, calculating the percentage change in the total number of vehicles sold in one month compared with the same month a year earlier. Some automakers report percentages adjusted for sales days. There were 26 sales days last month and 28 in March 2007.
