Good stuff. What is the net weight difference between your Saturn TDI and the VW that you pulled the drivetrain from?
(Sorry if I already asked)

I'm guessing about 100 lbs more for the TDI drivetrain. The car tips the scales at 2480 lbs with 10 gallons of fuel and a second battery in the trunk. I think a stock SL2 weighs a little less than 2400 lbs. It got 70.67 mpg when I filled it up today, pretty good considering all the road construction and traffic I've had to deal with this week.

That's awesome! Congratulations!
Are you using the stock tune or did you do a software upgrade?

It has a Stage 2 Rocketchip in it, good for 100 hp and 200 lbs of torque (up from 90 and 150, respectively). I was told that, driven sensibly, I would see an increase in fuel mileage with the Stage 2, so that's what I went with, and I'm not sorry I did it! I don't use the extra power very often, but it's nice to have when I need it.
Finally purchased the materials to make my smooth wheel covers, hoping to work on that tomorrow. And the car is still knocking down 70+ mpg (70.96 on my last tank), so I'm anxious to see what the wheel covers will do for it.

Saturn, 70 mpg ? How?
It is so spectacular, that is difficult to believe.
Is the Saturn an hybrid electric car?
What is the engine it uses?
Thank you much and congratulations!

Nope, no electric hybrid for this one! I engineered a diesel engine swap, using the drivetrain out of a '97 Jetta TDI, which is fairly fuel efficient to begin with. Some tuning, some aerodynamic mods, and a LOT of careful driving/hypermiling techniques helps push my mileage figure up there.

Saturn mileage
Dear Craig,
Outstanding mileage indeed. Saturn normal real world mileage (gasoline engine, petrol) is about 38 mpg.
I did an engine swap in my Mercedes 89, turning mileage from 26 to 35 mpg, using a Nissan non turbo engine. Car is heavier, though, but is still running on the hands of my son. The smoothest car ever build by Mercedes.
Here is my page of the swap:

It would be very nice if you can publish something similar.
Best,
OldBeaver

Wondered if you had given any though to constructing a "Hybrid" 205 Deg F thermostat to bump up your MPG's further. Info can be found here:
Mk2 thermostats will work in the ALH, so I'm thinking it's also reverse compatable

Haven't been here in awhile; I was getting low-60's over the winter, then got a new job in Rochester, NH, so now my commute is back roads of mostly 40-50 mph speed limits, plus a few 35 mph places where I go through downtown Berwick/Somersworth. My mileage has been improving between the warmer weather and becoming familiar with the roads; I was able to get 68.3 mpg out of it this week. Hopefully it will be a repeatable figure!
