ROI of MPG

I’ve been car shopping lately and thinking about what mileage I need in the new vehicle. The cars that I like and are more fun to drive hover just under 30mpg while the 35+ models tend to be a bit mushy on the gas (or tiny)

Today I came across this: http://www.comcast.net/articles/finance/20090811/US.GM.Volt.Mileage/

GM is unveiling a car that get 230MPG in the city!  I thought that was awesome until I came across 3 facts

  1. That mileage is in City driving
  2. The car is not shipping yet (and all my projects are ‘bug free’ until they ship also)
  3. The car is $40k

I wrote up a quick app to let me calculate how many miles I have to drive in order to recoup the $40k price tag.  Even comparing it against a $20k hybrid that gets 50 MPG I still have to drive almost 320,000 miles to break even! (at $4/gal)

    nope – one line javascript equation

    var answer= ( ( $("#cost2").val() - $("#cost1").val()) * ($("#mpg2").val() * $("#mpg1").val())) / (($("#mpg2").val()-$("#mpg1").val()) * $("#gas").val()) ;

    followed by a copy-paste of googling for “CSS FORM JQUERY”….

    This is worth considering “‘If you look at it strictly from a short-term payback perspective, without the tax credits, hybrids make absolutely no sense for the average driver,’ says Kim Korth, the president of IRN, a consulting firm in Grand Rapids, Mich. ‘The tax credit at least made it neutral, if not positive.'” (http://articles.moneycentral.msn.com/SavingandDebt/SaveonaCar/incentives-to-buy-hybrids-dwindling.aspx)

    There’s also this (a year old, but current when gas was very expensive):

    Currently, three of 15 hybrids breaks even in less than five years; in March, Edmunds says four of the then-13 models had a five-year payback. Edmunds calculates the payback period by calculating the list price, less rebates and federal tax credits, of gasoline and hybrid cars (or equivalents, a Toyota Camry in the case of Prius), the cost of fuel ($4.02 a gallon here), and fuel economy over 15,000 miles a year of driving. Take all this with a grain of salt. Thorough as the Edmunds calculations are, they’re affected by current pricing and rebates and payback periods can rise or fall dramatically in just a few months. And some similar vehicles have vastly different payback periods, such as the Chevrolet Malibu and Saturn Aura, or Chevy Tahoe and GMC Yukon. Currently, you’ll need almost a century of driving to pay back the $18,858 premium on the big Lexus.

    Here are the payback periods for the current crop of hybrids, as calculated by Edmunds.com:

    Toyota Prius, 3.5 years to break even
    Nissan Altima, 3.8 years
    GMC Yukon, 4.9 years
    Toyota Camry, 5.4 years
    Mercury Mariner, 5.5 years
    Ford Escape, 5.9 years
    Honda Civic, 6.1 years
    Saturn Vue, 6.9 years
    Lexus RX400H, 6.9 years
    Chevrolet Malibu, 10.9 years
    Chevrolet Tahoe, 13.8 years
    Toyota Highlander, 17.9 years
    Saturn Aura, 31.0 years
    Lexus LS600H, 98.5 years

    Those calculations don’t include any battery life considerations.

    Canon Powershot G11 dead pixels? I’m not also positive if it is what you call dead pixels, but on the LCD display, you can find little black dots. I know it is not dust or dirt about the lens, because it seems in photos I’ve taken prior to I had this problem. You will find about 3 or four black dots around the LCD display screen, and they’re not as well near to each other. I bought my digital camera in September. Ought to I send it in to Canon to acquire it fixed?
