Well. There are some things you have to consider, about Jeeps. Gear ratio.
Control, at speed.
I don’t know a lot about the latest Jeeps. But. Older ones, were designed for off road capabilities. They are not designed for high speed.
Gear ratio.
For example. In a sports car, the ratio, is designed for acceleration. The power of the engine is distributed to the axle, that turns the wheels that spin, by the size of the gears. In an off road vehicle, the ratio is the opposite of a sports car.
If you are driving through mud, or over rocks, you want there to be slower rotation of the wheels with the engine power pushing harder. And, you’ll be moving pretty slow. The faster the wheels spin, in mud, sand, or on rock, the less traction…
An off road vehicle on a highway, is like a sports car off road. It’s contrary to the design/purpose, of the vehicle.
Control at speed.
There are many variables here.
Ground clearance.
The lower a vehicle is to the ground, the better it can handle speed, and corners. But. The undercarriage of the vehicle(being low,) reduces it’s ability to clear objects on the ground. So. Off road vehicles, are generally higher off the ground, than others. But. That makes them highly unstable, at greater speed. If you turn too fast, you can flip the vehicle.
Then, there is tire size vs rim size.
A sports car, will have a larger rim, and lower profile tires. When you make turns, the rubber tires compress. So. At higher speeds, you want as little compression as possible. Otherwise, you are shifting the weight of the vehicle too much.
Off road vehicles, need traction control at low speed. So. They often have a smaller rim, and a larger tire. So. When the rubber flattens out (often people let some psi out of their tires, before going off road,) it gives the tires a bigger “footprint.” Which increases grip.
The off road vehicles, often have longer shock travel. And, softer shocks. Making them further undesirable, for higher speeds…
So.
Such vehicles, are simply not designed for speed…
As a side note.
I am fairly well traveled. And, IMO, people who drive Volvos are by far the worst drivers…
