They are, unfortunately, and the airflow patterns from watching raindrops isn't very clean. I was also starting to think about putting some rails on the A-pillars to direct the airflow over the windsheild rather than around the pillar (provide a splitter for the lateral flow).

Another definite is to get some more aerodynamic mirrors. I'm looking into the F1-style universal mirrors that'll bolt onto the door so I can clean up the A-pillars more.

Yeah, it's an automatic, and it's winter. If you take a look at my fuel log you'll see that my lowest tank was around 20 MPG on a really stormy week. I was also trying to keep up with a friend (who was leading me to his place), so I had to drive faster than I normally would, through heavy winds and rain.
I've been including every tank since I started the log, and some of them weren't pretty, so that brings the average down.

Though I did get a 26 MPG tank with some warm weather, and I've done some major work recently, so it should slowly start creeping up again.

I've also been using a K&N air filter to get a bit more power. But with my recent work, using the more restrictive Fram paper doesn't have as much of a negative affect anymore, and doesn't nearly have as much of a power loss as before. Keep an eye open and you should see it come up soon.
