The return of the Ford F-100

DETROIT (AP) -- General Motors Corp. is indefinitely halting a major overhaul of its full-size pickup trucks and sport utility vehicles as it deals with a drastic drop in sales of those products.

GM spokesman Tom Wilkinson said Thursday the automaker instead will work on more modest updates and enhancements as it shifts resources toward higher-mileage vehicles.

Ford's next big pickup development doesn't come for a couple years, when it hopes to launch a smaller, lighter and more fuel-efficient pickup dubbed the F-100.
