A growing number of people are hacking their hybrid cars to increase their gas mileage from the stock 45 mpg to about 80 mpg. An electrical engineer in San Francisco hacked his Toyota Prius with $3,000 worth of parts to allow him to plug it into his AC wall outlet at home. This allows him to drive about 20 to 40 miles on the charge using a 50-50 mix of electrical power and gas. The best part of this is that the cost of this nightly battery charge is only about a quarter.

If you think that’s good, a company called Energy CS has converted two Priuses to get up to 230 mpg by using powerful lithium ion batteries. It is forming a new company, EDrive Systems, that will convert hybrids to plug-ins for about $12,000 starting next year. Damn, I seriously may consider getting a Prius and hacking it to get 200 mpg. Kick ass!

  1. Just be careful. You’ll lose mileage once you put an Xbox and hydraulics on the car…

  2. I can’t believe it, my co-worker just bought a car for $25186. Isn’t that crazy!

  3. OK, let’s do the math with the EDrive.

    Assuming 20,000 miles per year, 50 mpg, gas at $2.50 per gallon.

    20,000 \ 50 = 400 gallons per year. That’s 1,000 per year spent on gas. Let’s say the Prius lasts 10 years. That’s $10,000 you’ll spend on gas in the life of the car. If you get 100 mpg (which this article says is realistic), you will save $5,000 in gas. Not bad. However, it costs $12,000 to install the Edrive. Charging the EDrive costs approximately $1 a day. Add another $3,650 to the cost. Your net loss is $10,650

    The only variable is the price of gas. Only if the average price of gas in the next 10 years hovers around $5/gallon, and that is the average, will you begin to save money.

    My conclusion is that it’s too early for the EDrive. When gasoline reaches a consistent 4 bucks a gallon, that’s the time to think about it.
