    Range depends on driving conditions and temperature.





    The much anticipated Leaf is nearing it’s U.S. debut, with pre-orders already maxed out for 2010, but now a new report is shedding light on what may be less than anticipated range expectancies for the electric car.

    Nissan has touted the Leaf as being the first mass-produced electric car to market, complete with a 100 mile range on battery power alone. But now a new report by Edmunds suggests that actual range will vary tremendously, by as much as 91 miles according to tests performed by Nissan.

    Officially, the Leaf is suggested to have a 100 mile range based on the EPA’s LA4 test cycle, yet five tests performed by Nissan simulating varying environmental and driving conditions suggest a range variance of 91 miles, ranging from a low of 47 miles to a high of 138 miles. Of the five tests performed, one was based on a Japanese test, and the following four were based on U.S. driving cycles, according to Edmunds:

    * 138 miles while cruising at 38 miles an hour with an outside temperature of 68 degrees Fahrenheit
    * 105 miles at a fairly steady 24 mph in city traffic with the air conditioner off and an ambient temperature of 77
    * 70 miles at a steady 55 mph on the highway on a hot 95-degree day with the air conditioning on
    * 62 miles in the winter – 14 degrees outdoors – with heater on and stop-and-go traffic reduced to an average 15 mph crawl

    The fifth example was, according to Nissan spokeswoman Katharine Zachary, based on “extreme driving conditions in a market outside of the U.S.” This extreme test resulted in a total range of only 47 miles, and occurred during heavy stop-and-go traffic conditions averaging just 6 miles per hour, while using the air conditioning on the maximum level to offset an 86 degree exterior temperature.

    These rather extreme fluctuations in range due to temperature extremes or traffic conditions are not new to electric vehicles, as Leftlane discussed in an article discussing the emerging push for electrification of vehicles in Israel.

    Range reduction due to weather is also not exclusive to electric vehicles, as gas-electric hybrids have also been reported to drop in range dramatically during extreme weather, particularly with extreme cold. This unavoidable fact may worsen the already prominent “range anxiety” that many would-be electric vehicle buyers suggest is the main reason for them sticking to tried and true petroleum-powered transportation.
     
  2. still a good step forward and such.

    none of what they say here is surprising or really provides insight. In stop and go traffic you get worse mileage than on the highway? NO WAI!
     
  3. So there is a possibility, that during the winter I may not be able to make it back home from work, sweet!
     
  4. This car is going to be a success...
     
  5. So basically it's like every other car on the road, but with a smaller overall range.
     
  6. and a cheaper fuel source.
     
  7. What is wrong with you people, this car is a POS and the range is not practical at all. Electric cars wont sell until they can get 500 miles from a charge and the batteries can be swapped out instantly with a nationwide charging station network.
     
  8. Moron.
     
  9. he's right.

    In other news Fiat Panda's are lame.
     
  10. Look, another Moron.
     
  11. The are tons of people that don't do 500 miles in two weeks. So I don't see why it can't succeed as a car to take to work.
     
  12. Well if you want to improve a product, you have to start somewhere. Technology will improve over time. I am all for electric cars for the masses, just so long as they keep the dinojuice for true performance cars.
     
  13. They won't replace every vehicle in their current iteration, but thinking there's no place for electric cars is silly. Probably 95% of peoples driving is within this cars range.
     
  14. To bad it looks like a POS.
     
  15. This is why the Volt, or something like it if it ends up sucking ass, will be the first really successful (more or less) fully electric car. Battery tech is advancing so quickly it shouldn't be long at all until full on electrics are GOOD ENOUGH without any backup power though.
