Dodge to offer 41 MPG (hwy) "Aero" version of 2013 Dart - 0.285 drag coefficient
(Chrysler photo)
Dodge has been touting the "world class" aerodynamics of its upcoming Alfa Romeo Giulietta-based 2013 Dart compact for a few months at least. But until yesterday, none of the PR contained any numbers.
They're going to offer a 41 mpg (hwy) "Aero" version of the car to compete with Chevy's "Eco" Cruze version, and Ford's Fiesta "SFE".
Dart Aero specs:
Quote:
- 160-hp 1.4-liter turbocharged four-cylinder engine
- Six-speed manual transmission
- Lighter-weight forged aluminum suspension components (replacing steel parts)
- Electric grille shutters that close to smooth frontal air flow when engine cooling isn't needed
- wheel spats
- Low-rolling-resistance tires

Additional Chrysler info about the focus of aero development:
Quote:
- more than 600 hours in the wind tunnel during the Dart's development
- Underbody panels run stem to stern
- Mirror design
- notch angle at the top of the header of the backlight to the trailing edge of the decklid
- even the tail lamp applique shape and rear corners were all designed and engineered for optimal aero performance
- integrated decklid spoiler incorporates a trailing edge shape for cleaner airflow separation in the rear portion of the vehicle, which optimizes the air wake

The first hard numbers I've seen for the drag coefficient:

The exterior design is clean (aerodynamic to the tune of a 0.285 coefficient of drag, which is good)

Though it's not actually clear from that article if 0.285 is for the "base" dart or the Aero version.

Update: John Voelcker at Green Car Reports clarified this morning in the comments of his article that 0.285 is for the standard car, not the "Aero" version.
It'll be interesting to see how much they're able to pare off that number with the extra aeromods. |

There's plenty of fat to carve off that cd. Also, there would still be many mechanical mods that would help as well. Nice platform to start from though.

And it only took marketing 3 hours to ruin everything.

Wasn't that long ago when every 4 minutes Chrysler (and the rest) came on the tube telling us we needed 400 hp in a pickup or SUV. And Daimler/Chrysler (idiots) decided the smart move was to make the entire lineup look like an SUV. This is a good start!  |

Will a hatchback be offered ? That rear glass slope angle is just killing the drag back there.
