Opinion about progress in 4x4 industry

[NejcT]

Recently I'm doing some research about overland traveling with 4x4, so I'm thinking and reading a lot of this, and I got something now stuck in my mind.

We all know that the best off road vehicles are the good ol' Land cruisers, Land rovers, Patrols and other cars that have beam axles, high ground clearance and the most important, old engines without any electric stuff inside, so they are easy to fix them in the middle of nowhere.

So the question stands, what is your opinion about the progress, in which the companies trying to be more environmental, using EURO standard engines, which includes a lot of electronics, computers, catalytic systems,... Getting the ground clearance lower because of the fuel consumption, independent suspension because less usage on real off road...

Is the progress looked in this way, that on all the interesting parts of Sahara, for example, they will put tarmac on and no beam axle will be needed?

Is the progress looked in electric cars, that have fuel range around 200km, to prevent some damage in environment (dunes, plants...)?

My opinion stands, that progress should go in the way, that the parts of the world, where 4x4 is mandatory, they should build old style 4x4 with some experience of the other. (For example, the last Land cruiser should not be with independent suspension and electronic, but combination from the experience of the 60, 80, 75 series, with some emission electronic, that are not important for engine running)

I hope, I will get some response, cause I'm really interested in other opinion about the problem...

Thank you.
