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.

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! XII/XXII/MMXII! - The Day After......
