Future technologies and Jeep's performance

I would like to start a discussion thread on what potential technological advances could realistically be made in automobiles in the next 50 years or so and what these advancements would mean for the Jeep.

Some examples: What if the 2035 Jeep Wrangler (probably not what it will be called) had a motor that weighed 1/4 what the current one does while delivering 400 hp and 400 pft to the wheels? How about a body and frame that was 200% stronger while 25% lighter? What about a completely new four-wheel-drive system?

What would changes like these in the factors that make up a Jeep do for its performance? I would really like to get some of the tech and mod heavy-hitters in here on this discussion.

Focus could be on overcoming observed shortcomings of the Jeep, could be extrapolation of general knowledge of theoretical technologies, anything that contributes.

I will be watching this thread with great interest.

How about an electric motor at each wheel? That would be an interesting concept for a 4WD vehicle. Push-button, computerized control of power distribution; no transmission, no transfer case, no differentials, no conventional axles, unlimited amounts of lift and flex without disrupting drivetrain geometry.......

OR, what about 2 electric motors, each in place of existing differentials......

I'm not even sure electric motors are light/powerful/small enough for any of these concepts to fly, but it's an interesting thought experiment (for me anyway).

you stole my thought,,, but it would have to be servo motors, cpu controlled. as for the flex it would have to be air cylinders, because we all know you cant compress liquid, the motores would have to be mounted directly to the wheel. cool concept, but costly.

Good stuff. I also had a similar thought about the 4-wheel-drive system/powerplant. I'm not sure it would have to be expensive though, today sure, but costs drop over time when the pressure to develop is there (and it certainly is in the automobile industry). (Side thought- OPEC nations will not likely be exporting electic motors )

Yeah, but I bet China will.

I think the electric motors at each wheel would be more practical as the prices of lithium based battery technologies, regenerative braking and more efficient (possibly magnet coil) motors become cheaper. If you think about where electric car technology is right now compared to 10 years ago and given Moore's Law, it's likely that the electric car of 2025 will be exactly what we want it to be. Now consider a folding softtop that doubles as an ultra thin solar collector/solar cell.

Solar cell-soft top: nice. I like the idea of a Jeep that needs no jerry cans on the back and has a range of 1000 miles of trails and remote mountains between fills/charges.

Just read an article... imagine a material that is (and I am quoting here) 10 times lighter and 500 times stronger than steel. Now imagine a Jeep where all the steel components (frame, body, well a lot of the Jeep) are now 1/10th the weight and 500 times stronger. (costs are high of course, but we are talking -2050, cost could be lower than steel by then). Couple that with some of the improvements in powerplant and power transfer systems, and improvements in four-wheel-drive that have been discussed in this thread, and you start to get a picture of a Jeep that could almost scale a mountain.

as far as the servo motors go ,, all you would need is a very small engine hooked up to a gen to supply power to them,,tractor trailer trucks have apu's that burn less than 5 gallons in 10 hours.
