Industry has a huge variety of subsectors that differ markedly in energy consumption and intensity (energy used per $ of shipment).
This chart depicts the 2010 primary energy intensities of U.S. industry by subsector versus shipments.
Losses due to rolling resistance are higher for heavier vehicles than for autos. In a Class 8 tractor trailer at 65 mph, 13% of fuel is lost to rolling resistance. Wide base single tires save about half of that today, more with next-generation tires.
The Hypercar (shown) achieved 53% curb-mass reduction without compromising safety. Its 14-part structure was much simpler than its typical 100–200 part counterparts made of steel and aluminum. A paper by Oak Ridge National Laboratory drafted a concept of a composite intensive body-in-white with 18 parts. Its concept had over a 60% mass reduction, also with uncompromised safety.
Composites have dramatically improved energy absorption over both steel and aluminum. Composite-based crush cones and similar structures built into autobodies can absorb 120, even up to 240, kJ/kg, vs. about 20 for steel. Crush properties can also be optimized by mixing costlier carbon fiber with cheaper materials like fiberglass.
Some autos currently on the market display specific aspects of Revolutionary design, and are progressing on the path towards truly Revolutionary autos.
