Actually, there has been virtually zero improvement in gas mileage over the decades. My '65 Chrysler Newport 383 V-8 got 16 at 70 on I-80 when new. My wife's Expedition with a 5.4 gets 16 -17 similar driving. True, lower emissions. But if you want 25, 35 MPGs, it's simple - get a tiny car with a tiny engine. That's really high tech!
