I have a 2003 VW Jetta wagon TDI (diesel) recently turned 73,000 miles with a life time of 55.53 mpg. Sometimes I drive for mileage and get in the mid 60’s or drive “normal” and get mid 50’s or pull a 2 ton trailer and get mid 40’s. Usually I drive normal.
I recently bought an electric moped, technically a motorcycle since it can go about 40 mph max, I am working on that. I plan to charge it via solar and use it to go to and from work once we move closer to work.
Those are impressive (and real) numbers. My coworker has a Golf diesel and reports numbers in the mid 50's. I often wonder why hybrids get so much publicity in comparison to these. I'll take a diesel over a hybrid anyday.
