    Has anybody got the file at the https://avt.inl.gov/sites/default/fi...vroletvolt.pdf. The calculations sound useful but the file has been removed. Can someone post the pdf or exact the calculations and post them?

    Over a long-distance on gasoline, the Volt is less efficient than the Prius. Gen I Volt will get approximately 41 MPG. The Prius will be able to get about 48 MPG. However, if the long-distance trip is blended with short-term plug-in commuting, then I would anticipate around 80 MPG with the Volt. Sweat equity is greater with the Volt.

    True, but it takes a LOT of driving to make up for that 40 electric miles at the beginning. Any trip less than about 200 miles puts a Volt in the "used less gas" column than any Prius except a Prime.

    Over the Memorial Day weekend, we took a 2-hour one-way trip that was about 86 miles on the Interstate. We achieved 46 MPG over 66 miles, going about 70 mph. Climate control was turned off. Elevation had some gentle hills (I-66 to I-81 south in VA). External temp was in the 60s.

    Keeping your speed below 60 mph will place your 2016-17 Volt pretty close to 50 mpg on gas. My recent round trip with our 2016 Volt for 135 miles, 70 miles on electric, and 52.5 mpg on gas. This was a fishing trip to Tillamook Oregon via Highway 101, speeds 60 mph max and 45-25 mph through towns, dry roads and 60 degrees. The gas mpg on the Volt was about 3-5 mpg less than I would have obtained with our 2010 Prius under the same conditions and climate etc.

    I drove my 2017 Volt from Denver to New Hampshire and back. Gas MPG was 38-39 MPG over the 4,000 miles. I tend to stay within 2 or 3 MPH of the posted speed limit on cross country drives. Colorado, Kansas, and Nebraska all have 75 MPH speed limits and the rest of the states were 70 MPH on the interstates. Primary, non-interstates ran the gauntlet from 25 to 65 MPH.

    I make a 180-mile trip twice per week. At 70 mph my round trip average sits at about 35 mpg. At 65 it is close to 40 mpg. At 75 mph it drops to 32 mpg. This is with 90-100 degree temps, AC on ECO 72 deg.
