A new type of steel is being used in light gauge vehicles and some models of light-gauge vehicles are now lighter than they used on previous models.
The new steel alloy, which is used to make the aluminium alloy that makes up the new aluminium alloy used in the new cars, is said to offer improved energy efficiency, reducing the need for an internal combustion engine and increasing the number of miles on a single charge.
A study by researchers from the US National Highway Traffic Safety Administration (NHTSA) has found the new alloy is as light and efficient as previously expected, but there is still a significant amount of work to be done to develop a production product that will be competitive with the existing aluminium alloy.
The NHTSA said that it has already conducted some research on the new steel, and is currently assessing the impact it has on vehicle weight and energy efficiency.
In its study, published in the journal Energy & Environmental Science, the researchers found that the new material offers improved energy density compared with existing aluminium aluminium alloy, and that the steel alloy also provides more efficient heating and cooling.
“It’s not like it’s like there’s not any improvements, but it’s a very good improvement,” said Peter Smith, a professor at NHTSD and the study’s lead author.
“It means there’s less energy wasted as heat is dissipated by the steel rather than by the aluminium.”
Smith added that the study did not identify any other material that was equally or more efficient.
NHTSD said it has yet to test the new materials for its vehicle energy density, but that it had conducted its own tests and found the aluminium steel to be an energy dense material, which means that it could be produced at a comparable rate to aluminium.
Ford says it has used aluminium as a fuel source since the 1950s, but with the advent of hybrid and electric vehicles, Ford now relies on aluminium as its main source of energy.
But Smith said the new composite aluminium, unlike previous models, has a significant advantage over the aluminium used in conventional aluminium alloy cars.
“I think this is a really important finding that could have a very big impact on the future of lightweight vehicle manufacturing,” Smith said.
“The aluminium industry has been in a position of having a lot of material that’s been used for a long time but they’re only using that for a very short period of time.”
We think this new material is a very different way to produce this material.
“Ford is the only manufacturer to have used aluminium alloy in a Ford F-Series and Fiesta car since the late 1960s.
The NHPSA said it will begin to assess the new fibre composites in the light gauge sector, and could take up to two years to produce an equivalent product that is lighter than the current aluminium alloy models.
Smith said Ford would take steps to increase the energy density of its aluminium-based products, but said that they would need to take longer than the time it took to make an aluminium alloy car.”
That would be a huge challenge,” Smith told the ABC.”
There’s a lot more to do in terms of energy efficiency in the next few years.
