Why production all-terrain vehicles are so boring?  

Or...
...like Peugeot Touareg?:

In the US...
ATVs are not like cars, but rather one-person vehicles like motorcycles. They tend to be ridden by "rednecks", hence the lack of interest in good design for the mainstream.

Defender for me 🙂
Defender for me 🙂 i'd love to own one

What you want
is the venerable VW dune buggy.

Polaris Razor is a clean design...
Recreational ATV's like the Polaris Ranger pictured below are very strange machines. They are not really all terrain vehicles at all. They are really good off road vehicles designed for deserts and dunes. They are designed for going fast and taking on air. They get used elsewhere, but the bulk of their markets is recreational usage in arid climates, or ocean dunes in coastal zones, at least that's what I have heard.
Work horse ATV's, the kind you see around horse stables, farms and ranches are basically good at going slowly over all kinds of stuff in any climate.
I think the person who said red necks drive the styling are absolutely right, though I might be more charitable and call them 18-40 year old males who are outdoor types, and who like motorcycles, jet skis and so on.
I've ridden the work type and the Razor and find the Razor a lot of fun, but wouldn't even consider it for work outdoor.
Razor's are a kind of super lightweight dune buggy. You run them in rear wheel drive only mode as much of the time as possible.
The work ATV's are like super lightweight WWII jeeps.
They are also all designed narrowly to slip between trees and narrow gates. You never use these things on steep slopes except to go straight up or straight down. Any angle off straight up or down, at least on the dunes where I ride them, is asking for a lateral roll.
If you notice, the Renault and the Peugeot are designed like old Meyers Manx (the ones based on an early 60s Beetle chassis). They are wide and they have wide tires. Good as they look, these things would be worthless off road where work atvs and recreational atvs are ridden. They are too wide. They would be vastly less prone to lateral rolling, but again, they would roll when the terrain got steep enough. And humans are extremely lousy at gauging horizontal slopes. The engineers that know what the hell they are doing, design them skinny for reasons: 1) to get through tight places, 2) to not compete remotely with big automaker's 4WD vehicles, and 3) to design out even the temptation to traverse horizontally on steep slopes.
Given the fact that less is more in any off road vehicle, I think the Polaris Razor, while certainly no work of art, is fairly clean and functional for the task.
