2015 Ford Mustang Is Powerful, But Aero-Efficient Too: Video

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.

You'll already be familiar with the Mustang's shape. While different from its predecessors, the car still has a distinct look, and Ford was keen to improve its aero attributes "without resorting to a characterless teardrop shape"--a little dig at some other fuel-sipping vehicles on sale today. Careful attention has been paid to the way air flows across the Mustang's surface panels, ensuring airflow stays attached--air bouncing about on the surface or causing turbulence increases drag, slowing the car down, causing wind noise and reducing economy.

Other details have changed too. The 2015 car keeps the Mustang's distinctive shark-nose grille, albeit smaller here than previous models. This means less air gets forced under the hood, where it can act like a parachute. Each of the three Mustang variants has a slightly different grille design, only allowing as much air through as each engine needs to cool and to breathe. On the turbocharged Ecoboost model, active grille shutters can adjust this to an even greater degree--opening wide for cooling, or closing to improve aero. Further preventing the parachuting phenomenon are the car's hood vents, which allow excess pressure to exit through the hood and over the car.
