it's partially about how and where you drive, i had a little 1.8L 4 cyl MPFI car, we'll call it a subahashi. on one particular drive the ambient temp was 105F it was running about 5500 rpm wound out in 3rd gear making about 105 mph. doing this for 1 hour resulted in a fuel usage of 10 MPG! it had very bad aerodynamics and not really much of an IC.

I nearly didn't make it to the fuel stop, had to drop down to 55mph and draft people till fuel was located.

point?

aerodynamics can help make or break your MPG at speeds above 55, and our datsuns aren't from the age where people drive 80+ mph daily / i do an mine can still get 30+ on the highway.

if you want to learn to drive more economically, get a vacuum gauge and learn to watch it and only give the car the minimum fuel it needs to maintain speed. that can gain a decent bit and you get a useful diagnostic tool.


strangely about 2 years later the same company released the most aerodynamic car of it's MY - the Alcyclone. hehe who has driven the flat 6 3.0l awd one? the 1.8t fwd one was pretty fun.
