The Downsizing in Detroit.

WAYNE, Mich. -- Ten years ago, the Ford Motor plant here churned out giant Expedition and Navigator sport utility vehicles that got 12 miles to the gallon -- and it was one of the most profitable auto factories in the world. Today, after a $550 million renovation, the 140-acre plant is a symbol of a very different Detroit: a greener, leaner industry focused on smaller, energy-efficient cars. The factory will now build Ford's newest compact car, the Focus, in four different and progressively more fuel-efficient versions, including an all-electric one that will be unveiled on Friday and go on sale this year.
