130km/h is just ludicrous. The consumption compared to 100km/h is about 50% extra and the time saved is wiped out with just one bathroom break.
Honestly I feel that driving faster is safer for me, since I tend to zone out if I don't have to pay attention to overtaking trucks.
If you don't drive while being sleepy this is just a matter of getting used to it. I used to drive to family visits 160-170km/h, but switched to 110 km/h (or train+bike depending on the circumstances). It feels slow at first, but you get used to it. The same when you do it the way around.
My SUV gets better mileage at high speed cruising due to the gearing. As long as you’re not constantly accelerating/decelerating and going with the flow.
what model would that be?

this can save even more fuel, if your SUV still uses fossil fuels and you accelerate at the optimal engine load and then glide. It's called pulse and glide.
Once you start working the pedal, mileage drops ~20%.
That's a big safety and pollution problem in itself.
