Science Friday Discussion of the Volt vs. LEAF

Aug 11, 2010

On NPR's Science Friday today Ira Flatow talked about the Chevrolet Volt and the Nissan LEAF, comparing and contrasting the two soon-to-be-released vehicles.  Phil Ross (editor at IEEE Spectrum) joined him in the studio as well as Nick Perry from Nissan and Tony Posawatz from the Chevrolet.

Ira Flatow asks, is the wait for EVs over?  Would you buy one?  Are they safe? How long do you have to wait to get one? What kind of plug-in do you want to see?

Nationally, for the demand for these vehicles as reported by Nick Perry & Tony Posawatz:

  • 18,000 Nissan LEAFS reserved
  • Chevrolet cannot comment yet on the specifics of how many Volts are in demand, but Tony says its "overwhelming"
  • Over 12,000 public charging stations in the ground this Fall, nationwide (19 states)
  • Chevrolet aims to be manufacturing the Volt in the US and exporting it to China by 2020
  • All car companies in the world are working on the electric drive, because governments are demanding it, not because customers are clamoring for it.

The show also responded to the concerns of many different callers on the expected topics: 

  • Price point and rebates
  • Charging and range questions
  • Safety of lithium ion batteries (they're safe). The batteries lose capacity gradually with age, after 5 years 80% capacity, after 10 years 70% capacity;...

Cool Cost Calculators

I've been thinking a lot about electric vehicles and have spent most of the summer talking to people about cars.  Over drinks at the brew-pup, at dinner parties, and cold calling folks in car related industries--- I've noodled a lot of opinions and perspective out of friends and strangers.  One thing that has come up consistently in these conversations is the cost of electric vehicles, followed by all the range and charging questions.  The cost issue is a nagging one in the back of my mind.  Yes, the cars cost money.  Yes, the cars cost quite a bit of money.  But wouldn't the sticker price be eventually smoothed out over the life of the vehicle? After all, you wouldn't be paying for much gasoline with most of the new EVs coming out, and in the case of the Leaf, you would only pay for electricity.  I've wondered about this all summer, so I finally started hunting through all my resources and I found a few car cost calculators online.  There are several out there.  Each make a different set of assumptions and none are perfect, but they do look at the life cycle costs of vehicle ownership, an essential thing to consider when making a decision about any type of car.   

The best one is the Project Get Ready Calculator by the Rocky Mountain Institute.  It allows you to select your state and inputs your current energy and gas prices.  It also allows you to choose from around 50...
