How "aero" is this 2014 Cadillac ELR?
|
I have never even heard of the ELR until right now, looks cool though.
A shot from the hip says 0.27. That roofline looks great, and Cadillac seems to have a way of keeping Cd down even with the giant grills and mirrors. |
Here's the overlay.

Keep in mind that while shape optimization is the "obvious" path to achieving low drag, the other important part is detail optimization. Two identically shaped vehicles can have drastically different Cd's based on differences in things like: cooling system capacities, wheels/tires, underbody design, trailing edge treatments, side mirror design, wiper location, etc.
All of which makes it hard to predict Cd based on a roof line/profile shot. That said.... realistically, this will probably be very close to the Volt. Because: with a range-extended EV, efficiency will be an important design goal, and it'll have similar drivetrain/cooling requirements as the Volt.) |

Well Mort, Either your wrong or Autoblog is wrong. You decide.

Looks like cab-forward. Thought manufacturers abandoned that. Glad they changed their minds. '98-'04 concorde had a cd of .288. And that was before gas was expensive and aero was more important.
|
Whatever the Cd is, it looks nice. :thumbup:
|
Looks great, wonder how much they could improve the wheels?

Looks similar to the Pontiac G6 coupes...
