Economist: 'Lightweighting' Automobiles. WHY? Saving Fuel Consumption:
Introducing at the Detroit Auto Show

| Economist |
To Know -- Lightweight Diet--Materials:
- Aluminum
- Carbon Fibre
- Magnesium
Economist: "But carmakers are increasingly focusing on what is know as “lightweighting”. And,,,new manufacturing techniques. Every gram counts."

| Corvette Z06: MotorTrend |
To Know -- Auto:
- Ford: Having a Aluminum-intensive design which is lighter
- Mazda: Reducing mass lug nuts on wheels
- Cadillac: Cutting edges of sheet metal panels
- Toyota: Prius made from carbon fiber reinforced plastic frame (CFRP); Same space, weighs 3x lighter
- Range Rover Sport--all aluminum body (less 800 pounds)
- Jaguar F-type Coupe--will be made all metal
- Chevrolet Corvette Z06--adding more CFRP parts, (roof, bonnet, etc.)
- BMW i3 battery-car: Carbon-fibre body
How?:
- 100 pounds = ~ 1 mile per gallon (mpg)--
- Lose weight = Less Fuel Consumption = Save $$ (it's almost like Humans...)
Economist: The carmaker has been tight-lipped about details, but the new F-150 version of the truck will feature an “aluminium-intensive” design between 500 and 700 pounds lighter than an equivalent one made of steel. Ford will likely sell more than 700,000 of the new trucks annually.
The is good news. The car industry will soon have to meet tough new emissions and fuel-economy standards. In America, for instance, regulators now require cars and light-trucks to reach 54.5 mpg by 2025. Designers and engineers are desperately searching for solutions that are not too expensive.
wow I like it good and better usefull post .thanks for share this posting.
