So the You Tube channel Car Wow did this test and though not purely scientific it shows a pretty good real enough world test to compare.
Now of course they have different battery sizes and shapes for the car/SUV but over all it seems to be as good a test as you could ask for if range is your main goal.

Thanks for posting that video, NEW2elec.  I found it interesting.  Apparently, range bragging doesn't always match up with reality and vehicle price.

In somewhat related news:  A half-page article in my newspaper today, published by The Detroit News and written by Henry Payne, is titled:  "Automakers tout electric future while building more diesels". That title should give you an idea of the subject matter.  In particular, GM was mentioned as introducing for the first time diesel versions of its Chevy Tahoe, Suburban SUV's and the Silverado pickup. The article states that: "But so efficient is diesel at moving heavy loads for long distances, that its resilience is creating doubts about the electric future touted by governments and manufacturers alike.

GM President Mark Reuss is quoted as saying that their customers "really don't care about the car diesel (scandal) that went on".

In the latest quarter for which data is available, sales of full-size diesel pickups in the United States were up 23% from the second quarter over the first quarter of 2019, more than double the sales of all cars and trucks. 

The article also states:  "Also complicating the electric-truck calculation is the stress of towing on battery range: Truck-testing authority TFLTruck.com, for example, has found that the Tesla Model X SUV only gets 30% of its range when towing 2,000 pounds."

The model X range loss from towing isn't the weight but the aerodynamic profile.  Transport Evolved has covered this a couple times and even has a big motorcycle touring trailer for their Bolt to demonstrate that it's not the weight, it's the aerodynamics.

Of course, that's not what the articles from the standard press lead with...

Thanks for the link!  The video was very good.

Yes, advanced AC drivetrains like Tesla's are less affected by weight, since downhills offset uphills with very little loss.  Aerodynamics are the lion's share of energy loss at highway speed, and rolling resistance (tires mostly, but also bearings) is second.  You'll find only a small difference in energy use between a fully loaded tesla and a nearly empty one on an equivalent trip.

Zero drivetrains are fairly similar, but a fully loaded motorcycle also may have things in the windstream that affect its energy loss, but I have had some of my best mileage runs with another adult human on the back.

Your welcome Richard, glad you liked it.  I found it to be a good infotainment mix myself.

The thumbnail picture caught my eye later on.  It shows they all have the same basic height.  Except the Tesla which is clearly the most aerodynamic.  The Jaguar the Benz and the Audi are all claimed SUVs while the Leaf and the Niro are hatchbacks.  To me the picture shows that the EV "type" is based mostly on marketing.

As we know the aerodynamic profile was the biggest factor to where they finished in the test.  Of course a bigger battery and less horsepower helps too.
