Blog Volt Maximizing MPG

Maximizing MPG

Note: For more from Alexandra, visit the "Ask Alexandra" tab on the Chevrolet Volt Facebook page.

The EPA has rated the Volt at 93 mpg electric and a combined 37 miles highway and city gasoline efficiency. However, Volt drivers will each use its battery and gas capabilities differently, getting different total “miles per gallon”  (a term not sufficient for a plug in hybrid, but I expect more explanatory lingo to come out of the EV community soon enough).

For example, I am getting a lifetime (read: 3 months) average of 135 miles per gallon. My friend Jeff U’Ren (seen in the video) is getting 235 miles per gallon. Ed Kjaer (also seen in video) drives about 100 miles per day, but because he has chargers both at home and at work his Volt’s gasoline engine rarely turns on.

Then there is the issue of how far each driver can get on the batteries. From my interviews this varies widely: Bill Nye routinely got only about 30 miles of range per charge, while Chelsea Sexton drove a Volt 57.8 miles on batteries alone. Most Los Angeles drivers seem to average about 43 miles of electric range, which is about what Ian and I get, even though we have a 3 mile hill to climb every time we drive home.

I wince when GM issues that tiny disclaimer on marketing material listing the Volt traveling an estimated 25-50 miles on batteries. Because gas cars don’t vary much in efficiency, I can see skeptics rolling their eyes at how wide a range the company says the Volt gets. They probably think most drivers will get the lower end of the estimated range, but the truth is exactly the opposite.

Not only do we need some new extended range electric vehicle terminology to replace outdated ones like “miles per gallon,” we also need to be more comfortable with the unique driving numbers each Volt owner will have, depending upon their lifestyle.

Greetings Amazing Chevrolet Volt EREV Fans,

Thank You Alexandra Paul for all you do...................

Some Facts to answer the above posts.....Glad to do this any time : )

>>>>Charles Browder, July 25, 2011
Mr . Browder, If Gm./Us Bank holds the same leasing arangement for 2012 yr as 2011 then the net cost to drive The Amasing Chevrolet Volt EREV will be aprox. $8800.00 for the 36 month lease for the base model !!!
>$350.00 per month with $2500.00 down plus up fronts becomes $400.00 mo. with just up fronts down.
> $400.00 a month x 36 months =$16000.00.
>At 30-40 miles driven daily electric utility charges $1.20 per day =$36.00 monthly>round up to $50.00 month
>Now not spending $250.00 month on Gas
>minus $50.00. . .
>$200.00 month not spent x 36 months=$7200.00 not spent over 36 month lease on gasoline !!

*****$16000.00 lease payments minus $7200.00 not spent on gas =$8800.00 net cost to drive The Amazing Chevrolet Volt EVRE*****

Mr. Ack, I understand your grid fears however let me put it this way :

"A conservative estimate is that we have an amount of electricity unused at night that’s equal to the output of 65 to 70 nuclear power plants between 6 p.m. and 6 a.m.," Senator Lamar Alexander (R-Tenn) stated before the Senate Energy and National Resources Committee. “I suspect that’s probably our greatest unused resource in the United States. If we were to use that to plug in cars and trucks at night, we could electrify 43 percent of our cars and trucks without building one new power plant.”

Quote-Senator Lemar Alexander (R-Tenn)

Mr. Browder, One of the biggest failures in business is to get the product in the hands of the consumer with the proper support channels for product question and complaints. An owner with a persistant unanswered need is the a recipe for failure.

Doug Wernert from the Volt team. Hope I can help clarify:
Our Detroit-Hamtramck plant builit 3,975 2011 Chevrolet Volts since start of production in November 2010. To date, nearly 3,200 have been sold to customers through Chevrolet dealerships, roughly 550 were delivered to dealers as demo units and about 150 held for internal purposes (marketing and engineering). The remaining 69 units are still available for sale. The 2,745 number you may have read are for the 2011 calendar year, not the model year.
One note: the Volt's delivered to utilities throughout the United States are refurbished pre-production units and total sales to fleets were fewer than 200.

Installation of a rapid charging system to replace a daily charge of 16 kw in 4 hours would require approximately 240v/17a or 220v/18a power requirement and an 80% rated circuit breaket of 240 volt/30 amps would be adequate for a maximum charge. A daily charging rate of 15kw @10 cents per kw is a $1.50 per day or approximately $45 per month if a maximum charge were used everyday.

This is by far, much cheaper than gasoline if you consider the following: 35 miles per day multiplied by 30 days would be 1050 miles for $45 per month. Obviously, it is a bargain that is offset by the additional cost of the batteries which will have to be replaced at about 100,000 miles (estimates vary but warranty is this given figure). If the cost of the batteries are calculated in overall savings, 100,000 miles per $7000= 7 cents per mile figured into the cost and an additional $73 per month in battery life replacement depreciation@1050 miles per month. Total cost per month then for all electric operation would be $118 per month compared to gasoline which would be 35 gals per month @ $4 or $140.

Although the numbers are very close, the advantage is a much greener environment while all local driving would require no gasoline at all. These figures are based on absolute usage which most will never use and some will see their gas usage as higher due to overall distance travelled which is still an overall savings. Generally most rural homes with distances of 12 to 20 miles would fit the model for all electric usage in the Chevy Volt as all driving could be done without the use of gasoline at all.

My greatest attraction for the Chevy Volt is the elimination of gasoline for all local driving and it appeals to me greatly. I believe I can get 150,000 mile life out of the batteries even though the warranty is 2/3 that. I also would like to eliminate our dependence on war to appropriate more gasoline for America's cars and this can only be accomplished if quit using the damn stuff. Many of my friends were in war zones and energy is a big reason we were there. Peace and green instead of pollute and mean.

I live 3 miles from my office and look forward to getting a Volt and essentially using no gas at all even though my Malibu only gets filled every three weeks now. Try living closer to your work like the Europeans and maybe gas won't be such a big factor. Wait until the dollar collapses and you see $7 a gallon gas, you'll scramble for a Volt.

I love the idea of a plug in but I see real problems down the road if this thing really catches on because our grid is not ready for this and prices will go through the roof. Our esteemed chief potentate would like to ram cap and trade down our throats and personally get into the carbon credits trading scam and please recall these Volts need to plug into the very same grid that will be most subject to cap & trade because the electricity is largely generated by burning fossil fuels. We still need cheap and affordable ennergy whether is is for electric for the Votls or Gasoline for traditional vehicles. We have our own energy resources if abundance if only we could get this horrendous monkey off our backs that is forcing us to buy from unsavory sellers in this world. What have I got wrong here?

Why do car manufactures waste so much of their advertising dollars on a car that is not yet available everywhere? If people are being over charged (not a pun), then word of mouth is good enough.

If the Volt is charged at home every day, how much has that increased your electric bill per month or, since electric rates are different in every area, what is the increase in Kilowatt usage per month??

Would Chevy care to comment on the exposure to electric and magnetic fields within the Volt? Were exposures measured to the occupants? If so what were the results in camparison to the WHO research into these exposures?

I have been driving my Volt for 5 weeks.
In Connecticut a full charge gives me 30 miles on the electric motor. I am told the milage per charge will Increase in the warmer weather.
Since the battery has to maintain a certain tempeture to be effective, on days where the tempeture is 80 or 90 degrees, will the cooling of the battery cut into efficiency of the electric motor?

I also disagree that gas vehicles dont have efficiency swings. My 2005 suzuki forenza will get anywhere from 33 to 23 mpg. It all depends on how aggressively you drive and the type of conditions you drive in. A big factor in the decrease in electric range, from what Ive heard, is the temperature. Driving around when its 0F outside is going to put a lot of stress on the heater and the battery temp control system. That's really my biggest debate on buying one up here in New England.

The size of the vehicle definitely does affect the efficiency at high speeds. I also drive a Nissan Titan, and in pretty much any condition the big V8 will give you a solid 16 mpg, (respectable for its size). The only time i see it drop is when i start getting above 70mph, and it starts to drop pretty quick.

I know that when I drive up my 2.5 mile hill, going 35 vs 45 doesn't make much difference in efficiency.

written by Evil Attorney, March 22, 2011
I was surprised about the wide range in battery efficiency in the Volt. My commute is almost completely freeway driving. If I limit my freeway speed to 60mph or less, I get a little over 40 miles per charge. If I drive around 70 mph or higher, that drops to the low 30 miles per charge.

I'm not convinced gas vehicles don't have similar efficiency swings. I think the relatively small battery of the Volt (compared with a gas tank) allows you to see the efficiency differences better. I would think a large, blocky SUV would be more susceptible to the wind resistance/efficiency issues than the Volt is.
