As much as it pains me to say, I have had to become a part time hypermiler. The commute is 70 miles each way. My family comes first. I leave at 5:45 AM and return home at 6:45 PM. To do that I have to go 73 MPH on I-95/I-40 for 50 miles each way. The remaining 20 miles I can use the hypermiling techniques. Still I manage 58 MPG average. I am content with that but I am not comfortable preaching to the VXers. I have guilt.
I miss the VX but the Prius is more comfortable and has AC. The AC is necessary during July and August when the temps were 95-110 F.
The commendation here lies in the fact that you were resourceful enough to get the vehicle that best suited your needs and still yields you great FE. I doubt that any non-FE minded person would have the foresight for that. They would just drive their Humvee at 80+ mph the whole way.
Good to see you back on the site. There's nothing wrong with 58 MPG! I can't quite manage that in my vx. i can manage over 60 on a few ideal trips, but overall am around 55. I think all of us vx drivers aim to get the mpg you got with yours but it is very hard to do. I am thinking maybe the LRR tires are crucial to this car. Also you did the complete belly pan, which probably makes a big difference.
The next two things i am going after on mine are the tires and the aero. I think I have the driving technique down fairly well, but not perfect since i dont have the super mid.
