It's still new in the automotive space, and Ford's taken a unique approach to its use.

You won't even be able to tell anything's different, unless you can somehow observe molecular structures with your naked eye.
Graphene is a single layer of carbon atoms, 
and its benefits could spread across many industries. While it's 
normally praised for its strength and conductivity, Ford plans on using it for a slightly different, but still beneficial purpose.
Ford
 announced this week that it intends to use graphene under the hood of 
future Ford vehicles. But its initial use won't be for its most obvious 
benefits, strength and conductivity. Instead, it'll be used in very 
small amounts in various covers to help reduce unwanted noise in the 
cabin. It's the result of research that has been ongoing since 2014.
Ford
 says it's found a way to utilize tiny amounts of the stuff in covers 
for the fuel rail, engine and various pumps. The automaker discovered 
that even half a percent's worth of graphene mixed with types of foam 
can reduce unwanted noises. Ford estimates that its new parts can reduce
 noise by 17 percent and improve heat endurance by 30 percent.
While
 adding covers usually adds weight -- penalizing fuel economy in the 
process -- graphene's lightweight nature means these components will 
actually lower overall part weight versus the pieces they replace. The 
parts were created in conjunction with two other companies, Eagle 
Industries and XG Sciences.
If you're wondering how long this 
magic material will take to end up in Ford vehicles, the answer is "not 
long." According to the automaker, graphene-integrated components will 
enter production by the end of the year, starting with the F-150 and Mustang, eventually making their way to other Ford vehicles. If your next F-150 feels just a bit quieter, it's not your imagination.
