Ultimately the structure of the seat and functioning components is where you want to cut, those have weight, not foam.
no its not, do you know how dense and heavy foam can be? Switching foam densities can easily net you several pounds per chair.

Which functioning seat components would you deem superfluous to the functioning of the seat

Pickups are exempt from CAFE actually...

Why surprised from the seats? They are some of the first things to go when people cut weight in racing vehicles

I seem to remember that pick-up trucks just perform poorly when it comes to CAFE regulations. I figured that they bring down the average for the company's line-up. Perhaps I am wrong, but even so, trucks aren't the best when it comes to MPG and companies must have an interest in getting those figures down.

Trucks themselves are just horrible in that department than anything else from the start, just due to the nature of its weight and size

They also all seem so boxy at the front. I'm sure they could come up with a more aerodynamic design, but perhaps that wouldn't be as good for capabilities. It seems like a truck that has great MPG numbers would sell well since it would stand out from all the rest.

Can you two do us a favor and READ about how CAFE actually works. There are different standards in place, the CAFE you're complaining about pickup trucks arent held to, they are judged by their own criteria, above half ton are exempt from CAFE

Corporate Average Fuel Economy - Wikipedia, the free encyclopedia
How CAFE Killed Compact Trucks And Station Wagons - The Truth About Cars
Bigger Pickups Are Result of Change in Fuel Standards - Bloomberg Business

Quote:
For the past few years, a quirk in federal policy has made it easy for Americans to keep supersizing their rides: Under CAFE rules that took effect in 2011, bigger cars have lower mileage requirements. For the first 30 or so years CAFE was on the books, the rules divided the market into cars and light trucks but held all vehicles in each class to the same fuel-efficiency standard. Automakers that sold only gas guzzlers, whether big cars or big trucks, had to pay penalties. That changed with a reconception of CAFE that began under President George W. Bush in 2008 and culminated in rules the Obama administration promulgated for 2011 and beyond.
Its hard to be persuasive if you don't know what you're talking about

I doubt there's much they'll change in design about those boxy fronts, it's a part of trucks, it's what makes a truck design a truck design, even more so as you go up the truck segment ladder.

Actually the boxier front ends aren't what does the most damage aero wise, its the drag behind that comes from the swirling air.

Some Examples

Quote:
For example, a new air dam below the 2014 Sierra’s front bumper successfully reduces drag because it directs air toward the ground and away from the truck’s rough underbody. And Sierra’s ducted flow path between the grille and radiator prevents air from swirling inside the truck’s front cavities.

Even the top of the Sierra’s tailgate and the center high-mounted stop light are optimized to guide air cleanly around the truck. And because Bloch’s team detected unwanted airflow between the cab and bed, new sealing has been added.

“We discovered that in the computational analysis we perform,” said Bloch. “The most harmful air between the cab and bed was coming over the cab and down through the gap, so we paid the most attention to that specific area.”
