Although General Motors and the EPA
have yet to disclose how exactly the 230 mpg figure is calculated, GM
did provide the following
nugget of information in today's press release regarding the
Volt's fuel economy:
Under the new
methodology being developed, EPA weights plug-in electric vehicles as
traveling more city miles than highway miles on only electricity. The
EPA methodology uses kilowatt hours per 100 miles traveled to define
the electrical efficiency of plug-ins. Applying EPA's methodology, GM
expects the Volt to consume as little as 25 kilowatt hours per 100
miles in city driving. At the U.S. average cost of electricity
(approximately 11 cents per kWh), a typical Volt driver would pay
about $2.75 for electricity to travel 100 miles, or less than 3 cents
Taking that methodology into
consideration, Nissan is now taking the opportunity to rain on the
Volt's parade with some lofty EPA numbers of its own for its new
LEAF EV. Nissan even went so far as to take a swipe at the Volt's
"Nissan Leaf = 367 mpg, no
tailpipe, and no gas required. Oh yeah, and it'll be affordable too,"
noted the company on its NissanEVs
Twitter page. Nissan went on to backup the previous statement
adding, “To clarify our previous tweet, the DOE formula estimates
367mpg for Nissan LEAF."
Nissan boasts of the higher mpg
rating because its LEAF features a 24 kWh lithium-ion battery, while
the Volt makes do with a 16 kWh lithium-ion battery. This gives the
LEAF a battery-only range of 100 miles compared to just 40 miles for
the Volt. However, the Volt has the advantage of being able to rely
on its generator to travel an additional 300 miles -- something that
Nissan cannot say about its LEAF EV.
The trash talking has begun, so it
should be an interesting battle in later 2010 when both the Chevrolet
Volt and the Nissan LEAF hit U.S. roads.
quote: "Nissan Leaf = 367 mpg, no tailpipe, and no gas required."
quote: so theoretically the Nissan is getting infinite MPG. Which means, anything between 0 and infinity is a reasonable claim.
quote: 2. If cruzing at 60mph in the Volt...would being on just the gas engine, or a gas+electric generator provide the best MPG? (remove the battery from this test..)
quote: Otherwise we are left guessing what the EPA thinks our driving habits will be, and how far we will drive in a single trip.
quote: Yes, I'm aware that this isn't exactly what GM is doing for their three-digit MPG number.
quote: With a Leaf, which is a silly name for a car, I'm not putting any gas in the car. Declaring any kind of value for MPG is pointlessly confusing.
quote: if I own a Volt, I can put x gallons of gas in it, then drive it until it stops. I can then measure the distance I've driven, divide that by x gallons, and get a value for MPG that's at least somewhat useful.
quote: How do you think that GM is getting 230 mpg?
quote: he Volt is achieving its 230 mpg rating primarily on its 16 kWh battery being able to used for 40 miles
quote: Check your facts :) It says right here in the article that you're replying to, that the Volt has a 24kWh battery. It's the Leaf that has a 16kWh battery.
quote: Nissan boasts of the higher mpg rating because its LEAF features a 24 kWh lithium-ion battery, while the Volt makes do with a 16 kWh lithium-ion battery
quote: Even if Nissan has significant savings over this figure, your still looking at a single component costing as much as most "C-Segement" cars.
quote: When charging stations pop up, like those being set up here in San Diego specifically for the Leaf, You wouldn't have to worry, too much, about running out of juice.
quote: You drive more than 100 miles per day?
quote: The Leaf's 100 mile range is project on the LA04 cycle.
quote: The trash talking has begun, so it should be an interesting battle in later 2010 when both the Chevrolet Volt and the Nissan LEAF hit U.S. roads.
quote: "The Leaf, on the other hand, costs about as much as a normal commuter car"
quote: You're still ignoring the cost. I figure it would take me ten years to recoup in fuel savings what I have to spend up front to buy the Volt.
quote: The LEAF $15k price noted here:
quote: The government (EPA) sure knows how to fudge a metric to the point of making it silly.
quote: 2) The internal combustion engine only N/A on the Leaf.
quote: I'm Rick James Bitch!!!
quote: "What did the 5 fingers say to the face.... SLAP!!"
