The next incarnation of Ford's (F) F-150 will be as tough as ... aluminum? By 2014 the company will be building most of the body of its signature truck out of that lightweight metal in a bid to boost its fuel economy, in what the Wall Street Journal calls "one of the biggest gambles in its 108-year history."
The aluminum body will weigh about 700 pounds less. That alone will improve efficiency, and it could pave the way for smaller, more efficient engines.
