Me too. I would never think that. In my opinion if weight is the problem, there are other items thay can make lighter, like frame, seats, booth hoods, etc....

I think this wheel is a small step in the right direction. What would make a bigger impact is using this technology to make automobile bodies and large internal components,aka seats. lighter. The wheel weight reduction is too small an increment of automobile weight.

I'm really surprised, I would have guessed it was all about the rotating mass.  I never would have thought that the drag from the wheel would make such a difference.

An improvement of 1.1 mpg is huge. Automotive engineers spend months and months just trying to find a few tenths of a mile-per-gallon. If these third party tests are right and if automakers find this to be economically feasible for production, then this is a gigantic step forward.

Ford F150 also

I also think the F150 was shown with an aerodynamic wheel that also incorporated shutters to close up the slots at high speeds and open for slow speeds (to provide adequete brake cooling).

I think it was also eVOLVE wheel design.

Many of the new adhesives we're featuring in this slideshow are for use in automotive and other transportation applications. The rest of these new products are for a wide variety of applications including aviation, aerospace, electrical motors, electronics, industrial, and semiconductors.
A Columbia University team working on molecular-scale nano-robots with moving parts has run into wear-and-tear issues. They've become the first team to observe in detail and quantify this process, and are devising coping strategies by observing how living cells prevent aging.
Many of the new materials on display at MD&M West were developed to be strong, tough replacements for metal parts in different kinds of medical equipment: IV poles, connectors for medical devices, medical device trays, and torque-applying instruments for orthopedic surgery. Others are made for close contact with patients.
New sensor technology integrates sensors, traces, and electronics into a smart fabric for wearables that measures more dimensions -- force, location, size, twist, bend, stretch, and motion -- and displays data in 3D maps.
As we saw on the show floor this week at the Pacific Design & Manufacturing and co-located events in Anaheim, Calif., 3D printing is contributing to distributed manufacturing and being reinvented by engineers for their own needs. Meanwhile, new fasteners are appearing for wearable consumer and medical devices and Baxter Robot has another software upgrade.
