Can’t help you at 75. A w123 turbo will drive at that speed comfortably, a w126 with 603 even better. But not efficiently.

Even a modern streamlined car will lose MPGs much above 55.

My Honda Accord Hybrid has an interesting operational zone where it’s more efficient running at 70-80 MPG than at 55 in continuous highway driving. It’s much more streamlined, and once you can’t be on the battery, I guess the engine is optimized for better SFC at higher load.
