Sorry, but I question this guys math.
660,000 miles/52 = 12,692 gallons
660,000 /25 = 26,400 gallons
26400 - 12692 = 13,708 gallons
$82,500 /13,708 = $6.01 per gallon...
Unless this person has been buying gas at more than DOUBLE (and at times TRIPLE) the average retail for the last 20 years, there is NO WAY he’s saved 82,500 with hi prius’.
Reality is he has saved money on his gas bill, probably somewhere in the $20-$30 range, or less, when you actually figure out the true cost of gas over his life of having hybrids... Then when you figure in additional cost to buy the vehicles, etc... his savings shrink even further...
Yes, he may have net saved some dollars, but its NOWHERE near where he is claiming.
The idea that using gasoline to run a generator to power an electric drive is more efficient than using it to run a motor to power the wheels directly seems to violate the laws of thermodynamics.
The math is about right. He saved ~25 miles/per gallon into 660,000 miles, gives you number of gallons saved. Multiply that by about about $3 per gallon and the numbers are pretty close to his estimate.
My opinion is that Hybrids make sense (for some users), while full electrics do not.
Full electrics still require the energy from the grid and the grid is less efficient at energy storage than petrol in a tank. So ‘someone’ is picking up the cost of electric, and while it should be the driver, that may not always be the case if public charging stations are used.
Hybrids make use of the energy storage of the petrol and get energy from the conventional gas engine, so the right person is paying for the energy and he gets the increased efficiency of the electric motor. No public services required and funds required for a new infrastructure and social engineering.
Good on ya!
Whenever I see “claims” and math involved together, I generally run the numbers.
This person is fool of poo. I came up with the same numbers.
