5000 miles +

After 5000 miles on the road, the 2010 IMW Seven has used approximately 24.2 equivalent gallons of gas in total electricity consumption.

That’s just shy of a 2010 Cadillac Escalade’s gas tank capacity if you want to compare it to a more recent car. But I don’t. I can’t help but compare Seven to my first car, a 1974 Chevy Caprice Classic. It had a 25 gallon gas tank and by the time my dad, Nick, handed the keys to me, the “old Chevy” got a whopping 17.8 MPG on the highway.

Seven has been driven the equivalent of across the lower continental United States and 2/3 of the way back on what used to be one tank of gas in my “old Chevy.”

At today’s gas prices, I can’t imagine taking that trip.

For the sake of easy math, let’s say the “old Chevy” got the best case scenario of 17.8 MPG for the whole 5000 miles (I wish!): at $3.50/gallon of gas that would cost about $983

At our current 11.8 cents per KwH electric rate, that same trip in Seven (averaging 200 MPGe and using 33.7kwh as our electric to gas energy equivalency conversion): would only cost about $99.42

Using those same numbers over the life of a vehicle…lets estimate low at 100,000 miles as the life expectancy the lifetime Fuel costs to drive each would be:

“Old Chevy”: $19,600

Seven: $1,988
