Gosh, there really is something uglier than the Pontiac Aztek.
-Yup, but you can't get a CdA @ 0,28 just for free - as it was the world's first aero-dynamically designed auto.
Its 2.6 L Siemens & Halske (sic!) engine of 36 hp pulled the 3000 lb car up to 70 mph a hundred years ago...
No early April joke here, check for yourselves:

Cheers
Johan (with a measured CdA of 0.34* on my time trial bicycle, and NEVER ever doing 70 mph)
*Bigger than my then car had: An Audi (Typ 44) 100 Avant with a CdA which achieved a record breaking 0.30 in 1982...
Yeah, but it took decades! In between could offer Edsel, Plymouth Valiant, late 50's Belvedere, 1966 Chevelle.Quote:

3000 pounds at 70 mph? I don't see adequate brakes, can't judge suspension; but the Autobahn wasn't known for bad paving.Quote:
