Seems rather implausible given how that looks in the back.

So did you read the entire article ? The car was tested in a wind tunnel run by a guy that worked with GM on the EV-1

I know what you mean though. Everything about that car seems an aero mess.

It has a barn door flat front end, gaping wheel wells and apparently was originally tested without even a belly pan. Even the body trim around the windshield looks to be an aero mess

Did anyone discovered what includes the "ECO Technology" package? Pictures of them?

"These include lowering of the body, the sealing of joints at the rear window and the cladding of chassis components at the rear axle."

It seems that these little changes are not so much cosmetic in themselves as intended to accomplish some of what other more effective and easier mods might accomplish but also make the car "uglier" in the eyes of potential buyers. I'm thinking here about the comments about that .20 Cd camaro up above a few posts back in this thread. That car mainly used a thoughtfully designed but "garish" front airdam. Mercedes wouldn't want one of those on the new b-class!

Too bad the B class are never sold in the US. I work for Mercedes but they don't offer any car here that I would want to buy.

Very interesting belly pan, sort of wedge shaped, being lowest to the ground by the front wheels..

the new mazda 3 has a Cd of 0.26 - not bad! the point I wanted to make was that they show what the spoilers in front of the tires does - also on the b class.

Nice video. Thanks. The hole in those tire spats/spoilers seems novel. Is it to assist cooling brakes or maybe to minimize the enlarging of the effective frontal area by creating blasts of air to the sides? I was also struck by how they represented the installation of body panels under the car: they opted for spot panels instead of a full sized bellypan. The biggest panel covered the whole engine bay.

It streamlines the flow of air past the wheels.
BMW call it the Air Curtain - we've had a thread on that before.
