There's one. Go to a Car and Driver article about cars with extreme ranges, namely those over 650 miles, and they will start listing out particular years' models over a 10 year period in order to get to even ~10 models, and most of them are EcoBoost or variants or poor selling hybrid versions of other cars.
Assuming a 1000km range is a very strange thing to do, as it's a fringe feature that almost no one needs or wants! Recall that "almost no one" means that there's still some, an existence of a handful of people on HN is quite consistent with "almost none."
my 2010 F-150 with the notoriously terrible 5.4L gas engine seems to manage 1000km range. there's absolutely nothing efficient about it, it's just got a big gas tank.
Of course I didn't pick it for range, I looked at price and miles of what the local carmax had and then separately looked up how tall the top of the windshield was.
Which I would expect to typically find something that's, um, fairly typical on characteristics I wasn't selecting on.
