What ever happened to that Benz Boxfish prototype?

if you look at the e class coupe and be boxfish here's more than just a few panel folds that look similar to me, so it's not because the boxfish itself isn't put in production some of the (less obvious) aero lessons learned from it aren't put on pruduction models.

...I kinda like the little "fin" on the trunk deck lid (rear looking camera or brake light?)!

I think he's referring to Chevrolet's Citation-IV concept which was out at the same time as the Ford Probe-IV.But I think he's giving the Chevy the Ford Cd.
The Chevy was 0.15or .16 and Ford 0.14.Then Ford went on to do the Probe-V which came in at Cd 0.137.
I think the Chevy is in my photo archive on front page of CAR and DRIVER,who road tested both cars.I intended to do a "case-study" on both cars,haven't got around to it.
Where do the days go?

They go into fixing Microsoft's blunders.

I wondered if he was referring to this car as well (GM's Citation IV with generous teardrop taper. Cd0.15 - according to your gallery) - though it's also got seams, which the Daimler guy said it didn't.

Hi Darin,

Did you say that Aerohead has a gallery? Can someone post a link to it, please?

I mis-spoke with respect to the Citation.It has Cd 0.18 not 0.16.

I found my article about a Cd 0.18 Mercedes that achieved 100 mpg a decade or so ago.I'll photograph it and have Al transfer it onto the net Saturday.
