Cars have been under EPA rules for many, many years. Even though they are under EPA rules they have been getting fatter and fatter and fatter over the years.
Lets pick one and see what it has done over the years.
1970 Challenger (a car I own)= almost 3,500 lbs. 2018 Challenger= almost 4,500 lbs!!!!!
Almost a 25% increase in weight!! Even the Dodge Demon (Dodges factory drag car) weights 4,500 LBS! Look at a Ford Thunderbolt (Fords factory drag car) weighed 1,300 lbs less!!
And yes I know "some" of this stuff is mandated by the government. Things like airbags and cats and things like that are mandated but still add a lot of weight to these cars. Things like 132 cameras and butt heated and cooled seats, 45" TV screens are not.
I say the manufactures will save a few 100 lbs and that's about it. Much like when Ford went with an aluminum body. A lot of GM trucks still weigh less or the same as the Ford trucks.
Trucks have been getting bigger and heaver for almost 100 years. I don't see the trend changing anytime soon.
