Yep, it's that time of the week again: 2010 Ford Mustang teaser day. This time the Blue Oval boys have dribbled out a sheet metal crease apparently belonging to the hood bulge or "powerdome" in marketing parlance. All amusing since we've already seen the hood anyway. We'd really rather see what's underneath, particularly if it's an engine that says "EcoBoost" on the valve covers or something. We'll get to see the whole works at the LA Auto Show next month, so try to reserve some excitement for then.
