    It seems like all VW TDr’s that are for sale advertise “35 mpg”.

    Does anyone really (as in really) get 35 mpg?

    The best I could ever do was about 28. (And that was during the Carlisle Autocross where Ed beat me and Wobby said it looked like I “was out for a Sunday drive”.)

    25-26 with the old engine. I expect better from the Soob. One Speedster guy (with a carb on his!) claimed 38 or 39 running from Canada to Florida and back.

    But, no, it’s not possible with a type 1.

    35 MPG might be possible with a VW 40HP engine in a TDr, tuned for efficiency and driven to maximize MPG…

    There’s some weight reduction with the TDr, but the aerodynamics are awful — and get worse with speed. 

    I think you’d likely need to change the gear ratio (e.g. use a “freeway flyer”) to get much over 30 MPG out of a 1500 or 1600 engine.

    Ethanol-free has to help the gas mileage a little.

    I think I read that ethanol free gas gives you about a 5% increase in mileage. (After the carb is adjusted for the richer fuel.)

    Last I checked it was about 25 give or take on the highway. I put a new carb in recently though and hopefully that will increase efficiency a bit but I haven’t taken it out on a long enough trip to find out yet.

    I get just over 19 mpg around town on mostly two-lane roads with lots of curves and a few traffic lights, and rarely doing more than 45 mph. Even when I get out in the boonies, I stick to county roads and seldom exceed 30-35 mph.

    I guess we all agree, as I thought, the 35 mpg claims are a bunch of malarkey.
