    Tolls are 85mpg and yeah my 2011 Jetta Sportwagon gets 40s regularly. But the point about the Jetta getting 36mpg at the same speeds where the Taco gets 13mpg is where it really hurts. And this is all regular driving within speed limits within 30 miles of the factory.

    I'd like to add that this is the primary problem with full electric vehicles. ICE can handle the drag at high speeds, electric motors are much more efficient at low speeds.

    Yes. Also, how hard you accelerate affects it too.

    33K mi. on my '16 DC OR AT - stock height, suspension and tires at 34psi. Still avg 19mpg around town (lots of rolling hills here) and a solid 21-23mpg on a flat fwy @ 70mph. If I drop to just 65mph on a flat fwy it climbs to 25mpg. (best I've recorded on a trip). Raise it to 75-80mph, mileage drops to 18-21. Best thing to do to raise mileage in city driving is to manually shift in sport mode. I've been doing it for 2 yrs now. Raises my mpg, stops all the gear hunting up and down, keeps it in the torque band, and is a much more fun and sporty drive. (I hold it between 2000-2500) 4th most of the time in city driving.

    Where I live, the limit is 65 but its almost regular for people to go 75-90+ of course after 80 youll be scouted for a ticket.

    Got a TRD Pro here and get 20-22 mpg in the city and 16-18 mpg on the interstate, all rolling hills and mostly between Montgomery to Atlanta. On the way back to Atlanta I get 16-17ish mpg and back to Montgomery I get 18ish mpg. I usually keep it around 78-80mph. Good to hear other people are having roughly the same experiences. I've put about almost 20k miles on mine and even with my light foot I still can't manage to get any higher on the interstate and I try to coast it down the good old Piedmont hills. Looking at my Fuelly app I'm getting 19.6 avg mpg.

    Fake news. Electric motors are more efficient at high loads, but the higher load caused by increased drag at higher speeds still has negative impact on range. Similar to ICEs.

    Completely normal I’ve tried multiple tests and the instant I go above 70 mph my mpg takes about a 5+ mpg hit. If I do 55-60 mph I easily average 23-24 mpg. Over 70mph I average 17-18 mpg. I do a ton of mixed driveing and found this to be the case.

    Except that our gas is so much cheaper. That's why so many drive gas guzzlers. I can get unleaded for less than $2/gallon while in CA it's over $3.20 for the same gas...

    When we burn California gas rainbows exhaust out tailpipe.

    But seriously, I've rented sedans twice in Texas, both times got upgraded to big SUVs. It's like they want you to burn more gas to make up for the cheap prices.
