With the introduction of a new generation of high-tech cars like the Chevrolet Bolt EV and Tesla Model 3, automakers are turning to aluminum roofing to save money.
But while many people are still buying aluminum roof coatings in droves, prices have increased by about $100,000 for a typical sheet.
And while some of those extra costs may be offset by savings on fuel and other expenses, there’s also the possibility that the additional costs could hurt an already struggling car manufacturer.
“If aluminum is cheaper, there are less cost-saving opportunities, and that’s why you’re seeing so much demand for this,” said Paul Novembre, a materials scientist at the University of Texas, Austin.
“There’s always a tradeoff.”
In its bid to cut costs, GM said it will be lowering its price tag on the $19 million aluminum roof covering it’s used on the Chevrolet Volt.
It also is lowering its prices on a $12 million version of the same product.
That reduces the total cost of the aluminum roof by about 25%.
But the $20 million version, which GM says it will also offer on some other models, will add about $3,000 to the price tag.
The Chevy Volt was originally expected to cost $31,500 for a single roof, but GM said that will drop to $24,000.
For the $30,000 version, the savings are $1,500.
GM also is offering the aluminum-coated Chevy Bolt EV for about $24 the same time, but it also is selling a $15,000 vehicle.
The Chevrolet Bolt is still a solid-state battery, so GM is lowering the price of the battery to $12,000, which will be $2,500 less than it cost the Bolt EV.
But the Volt’s new version of its aluminum roof has another major drawback: It will not be available until the end of 2018.
The price will also drop to just under $24 for the full $20,000 roof package, or about $9,000 less than what you’d pay for a similar sheet of aluminum.
The savings on the new sheet are more than offset by the cost of making the new aluminum.
GM said making the aluminum panels will save about $50,000 in materials and labor.
The cost of building the sheet of sheet metal is about $8,000 more than the cost for the aluminum that the car is already equipped with.
To make the aluminum, GM has cut down on the amount of work that it would have to do on a standard sheet of plastic sheeting, which is made of a thin sheet of polyethylene, a plastic that is also used in some solar panels.
The GM sheet of paper was made from polyethylenes, which are easier to work with.
But there are still risks associated with making the sheets.
The sheeting can fail under high temperatures, making it susceptible to cracking and cracking and crackage, which can cause a leak.
And the aluminum itself can rust, which may lead to a fire.
To save money, GM decided to go with a sheet made of an extruded aluminum, which means that the metal is only extruded once.
GM has not said whether it will use the same extruded sheet material for the new GM aluminum roof, which was manufactured by a company called Advanced Materials, Inc.
The aluminum sheeting that is being used on GM’s new Chevy Bolt EVs was manufactured using the same sheeting as the Chevrolet Tahoe.
But that was also manufactured by Advanced Materials.
The new sheeting was produced by Advanced Technologies and is a special material that can withstand temperatures as high as 4,000 degrees Fahrenheit, which makes it much stronger than the sheeting GM is using.
In an emailed statement, Advanced Materials said that the cost savings are significant because it is more cost-effective to make the new materials.
“These materials are made of highly durable, flexible, flexible-like polymers, which enable us to produce a sheet that is much stronger and less prone to cracking than the existing sheet material,” the company said.
“It is a more cost effective alternative to making the original sheet material and is also a much lighter material, and thus, lighter, and therefore cheaper than the traditional sheeting.”
