the fuel economy is significantly better nowadays on gasoline cars. My Tuscon SEL PLUS get 30.4 MPG at 78 mph..
That is on the interstate of course but not bad for a decent size SUV..
I don't know what a hybrid would get but I would not complain about excess of 30 MPG with an SUV..
Similarly, my Sonata Sport gets 38 MPG at 78 MPH when traveling on the interstates...
Not sure how much advantage there is with a hybrid vehicle..
