Meet Ford's 2015 Mustang

It's no longer enough for a car to be merely fast, or to look great, or to use as little fuel as possible. Modern cars have to do all of those things and more, which is why Ford's 2015 Mustang isn't just its most technologically-advanced ever, but its most efficient too. Much attention has been paid to its new four-cylinder engine, lining up alongside the V-6 and V-8 units for the first time in decades. But Ford Motor Company [NYSE:F] has worked hard on the car's aerodynamics too--not a traditional strong point of pony cars.
