No, we won't be getting 50 mpg with a Suburban sized vehicle with internal combustion at all at any time in the forseeable future. (If gallons of "fuel" are even applicable).

Nothing better than cruising down the highway with a Prius in front of me with both of us running 80. I bet my mpg is better than theirs at that point.
Or we could switch to algae diesel and grow all we want and run them into the ground at 18mpg all day long.
And by 2000, we'll have flying cars....
Trust me, I know all about these new CAFE standard regulations. Passed by politicians who know absolutely nothing about engineering. It's really quite ridiculous.
You really think in just 2 redesigns, that the Suburban can go from like 13 MPG to 50 MPG? And remember that automakers usually run engines for 2-3 car generations because of the massive cost in developing new engines. So typically, the engine in today's Suburban could still be used 10 years from now.
For such an efficiency hike, it would have to be a hybrid with a battery the size of a freaking Corolla under the floor.
Think about it, Toyota does everything they can to squeeze 50 MPG out of a Prius. And Toyota has stated that the next Prius' goal is 55 MPG and that they are having a really hard time beating their own record. So we'll likely see a PRIUS at 55 MPG through 2019. A Prius! How the hell are entire fleets filled with trucks and SUV's supposed to average about that a few short years after that???????????
NOT going to happen. Just wait and see. Bureaucrats just can't create arbitrary numbers and dictate that engineers have to miraculously meet them.
Volkswagon diesels get tremendous gas mileage
Hybrid technology has boosted MPG with comparable vehicles at an initial economic cost, but MPG ratings have turned out to be inflated. Regenerative braking is a great way to recover energy that would otherwise be wasted. Check current F1 tech with the Kinetic Energy Recovery System. Aerodynamics is another area where F1 is at the cutting edge. No improvements in combustion tech, though.
Keep in mind I'm just making realistic arguments.
I'm a huge fan of fuel efficiency. One of my favorite cars is the widely hated Prius. And I drive a Yaris mostly for it's fuel efficiency (and reliability).
I bought the Yaris in 2008 when it was the most fuel efficient vehicle aside from the Prius available in the US. That's why I bought it.
Purplesky, what do you drive.![]()
I am also just making arguments and you are correct that a 50mph Surburban will be tough to make in 10 years but I really think the technology is already here and will be used in 10 to 15 years.
I drive a 305hp Turbo Subaru. Its quick and great in the snow and rain but my MPGs suck. I live very close to work so my gas costs are low.
If I had a real work commute I would buy a really fuel efficient car as a daily driver.

Also in the aerodynamic discussion is that flashy is often anything but aerodynamic. The superbikes of the late fifties and early sixties were far nor aerodynamic than the crotch rockets commonly desired by the Joe rocket types.Hybrid technology has boosted MPG with comparable vehicles at an initial economic cost, but MPG ratings have turned out to be inflated.

I enjoy the numbers in my investment accounts that give me a relatively stress free existence (in regards to financial concerns).It doesn't have to be new but it is nice to have something you enjoy.
