Carmakers Steering Away From Steel in Order to Meet Fuel Economy Standards

usnews.com -- Faced with increasingly stringent benchmarks—the government's new Corporate Average Fuel Economy (CAFE) standards require a passenger vehicle fleet that averages 54.5 miles per gallon by 2025—carmakers are taking another approach to achieving better fuel mileage: shaving weight off vehicles by experimenting with lighter materials.

Automobiles have long been made from steel—a very strong, but heavy material. Now manufacturers are experimenting with new materials—ranging from aluminum to carbon fiber composites to metal alloys—to help companies reach the ambitious fuel efficiency standards.

"They don't have to make these changes immediately, but there's much more a sense of urgency now," says Bruce Belzowski, research scientist at University of Michigan's Transportation Research Institute.

Carmakers Steering Away From Steel in Order to Meet Fuel Economy Standards. Vehicles can be made lighter for higher fuel efficiency AND be very strong too. Aluminium, exotic metals and alloys, titanium, carbon fiber, strong plastic composites are a few materials to make car bodies and parts from. Very strong driver and passenger cages and numerous air bags placed on all sides of the inside occupant areas, design vehicles to absorb front/rear/side impacts. Defensive driving and vehicle sensors, cameras, radars and gps connected to a computer to help get from one place to another. All changes and improvements to the vehicle will be at a higher cost than todays current vehicles.
There will be much higher repair costs when accidents occur too.
Whatever the size or shape of the vehicle, vehicle manufactures Produce and the population ‘Drives’ vehicles with high MPG, are very safe, reliable, have a ‘reasonable’ cost and a good ‘value’ for the money.
The price of fuel at the pump is too high!

All you environmentalists, you knew it would sooner or later come to this, and even worse. 54.4 mpg? Totally unrealistic.

Saturn was great, at first. Then GM ignored them for ten years, then turned them into just another GM division, no different from every other GM division.

I think it can be done before 2025. We have been experimenting with new materials for a long time. Saturn did it. Oh there no longer around.

Government mandate for higher mileage = less safe and desirable vehicles. And we won't have much choice about it.

Lower cost to build,(plastic).
Cost to the public? Not as safe and no cost savings on the tag price.
Perfect for the auto industry.
Not so good for the public.

Because of the idiotic CAFE standards automakers will once again trade safety for fuel economy. People will die because of these new fuel standards!

Safety must be given high priority, even if it costs that little bit more to do some extra R&D. I'm sure people will pay a little extra knowing they'll be safe in the event of an accident, and the decreased weight will mean better fuel economy so they'll be saving money on gas to offset the higher initial cost of the vehicle.

I always feel better in a car that's heavier & made of steel. Its safer is there's an accident.I know it is a sacrifice as far as gas mileage is concerned.

Many of the composites being used in car manufacturing are not only lighter but many are even stronger than steel.
