Ford has big plans for its next-generation F-150 pickup; it's set to be a game-changer in terms of utilizing lightweight materials in a full-size pickup truck. Just a year or so after GM revealed its all-new Chevy Silverado and GMC Sierra, the new Ford F-150 could likely turn out to be the formers' worst nightmare. Ford has already announced the new F-150's frame and body will be composed of new aluminum alloy that will significantly cut the truck's weight.

However, sources have recently told The Truth About Cars that Ford has run into a hurdle in the pre-production process. The issue is with the aluminum body panels in that the material "did not meet internal forming requirements for the 'tooling tryout' phase of pre-production." Translation: the panels don't properly return to their normal shape after being hit with a dye. The F-150's launch will now be delayed by up to ten weeks, and the Memorial Day debut is now called off. Once the suppliers get the aluminum issue sorted, this new F-150 could very well be the truck GM should have built if it wants any chance of overtaking Ford in this hot-selling segment.
