>What ICE car exceeds that?

When it was new (3 - 5 years old) my Dodge 2500 turbo diesel with a 120 liter fuel tank (31.7 US gallons) went 1,000km (620 miles) per tank. That's highway miles of course but 1,000km per tank is not exactly mind blowing it works out to 23.5 Imperial mpg or 18 US mpg.

An old cow-orker of mine said his old VW Rabbit diesel manual trans did 80 Imperial mpg (66 US mpg) on the highway. I have no way to verify that could be 10% BS. I've seen 50 US mpg stated (60 Imperial mpg). But who know synthetic oil, slim tires, highway miles, slow speeds all that may get it to the 70s mpg.
