My 2006 Sonata V-6 was advertised at 30 MPG highway. I can get 35 sometimes. And it cranks! GM’s V-6s were claiming 30 MPG highway until the last couple of years. Don't know why their down to 26 MPG now.
Don't know why their down to 26 MPG now. The EPA changed the calculation to better reflect "real world" conditions, which had the effect of substantially lowering estimated mileage.
I've always gotten more than the EPA estimate, but that's just me...
