Metal/Plastic Car Wheel Boosts MPG
2/8/2013

The eVOLVE Hybrid Wheel made of metal and plastic, designed for the 2012 MYFord Focus SE, has shown an increase of 1.1 MPG highway in third-party tests, compared to the car's standard production wheel.  (Source: Lacks Wheel Trim Systems)

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.

Artificially created metamaterials are already appearing in niche applications like electronics, communications, and defense, says a new report from Lux Research. How quickly they become mainstream depends on cost-effective manufacturing methods, which will include additive manufacturing.
SpaceX has 3D printed and successfully hot-fired a SuperDraco engine chamber made of Inconel, a high-performance superalloy, using direct metal laser sintering (DMLS). The company's first 3D-printed rocket engine part, a main oxidizer valve body for the Falcon 9 rocket, launched in January and is now qualified on all Falcon 9 flights.
A new thermoplastic composite for high-speed, high-volume injection molding has tensile strength that's close to, and sometimes better than, either lay-up composites or metals.
Lawrence Livermore National Laboratory and MIT have 3D-printed a new class of metamaterials that are both exceptionally light and have exceptional strength and stiffness. The new metamaterials maintain a nearly constant stiffness per unit of mass density, over three orders of magnitude.
Smart composites that let the material's structural health be monitored automatically and continuously are getting closer to reality. R&D partners in an EU-sponsored project have demonstrated what they say is the first complete, miniaturized, fiber-optic sensor system entirely embedded inside a fiber-reinforced composite.
