The man ignorant of mathematics will be increasingly limited in his grasp of the main forces of civilization- John Kemeny
Math was never one of my favorite subjects in school, but one I thing I knew was you needed to have the right numbers to have any chance of getting the correct answer.
One favorite activity of Volt owners and critics alike is to break down the cost of driving the Volt by taking into account the cost to charge, the EV range of the car, the length of a round-trip daily commute and other factors. Recently, there have been some number circulating online about the cost to drive the Volt that are flat wrong – either the person doesn’t understand how the Volt works or they are paying roughly ten times the national average for electricity (in which case, they have other issues). But don’t worry – we're here to help set the record straight.
We’ll get into the math in a second, but first know that our owners have driven more than 25 million miles, with nearly 2/3 of those miles using no gas at all, and most customers traveling over 900 miles between fillups. We’ve seen stories from owners who, one year after taking delivery, are still using the same tank of gas that came with the car and others who have driven the Volt across the country. But the question remains – how much does it cost to drive the Volt? Get your calculators ready and I’ll share with you some numbers.
First, the Volt gets an EPA-estimated 35 miles of EV range, and we estimate you can get between 25 – 50 miles of range depending on the three T’s: the outside Temperature, the road Terrain (flat vs. hilly) and your driving Technique. If, on a cold day, you blast the heater and slam on the gas pedal (like some are known to do), your range will be a little less. This video gives you some tips to maximize your range.
Next, you need to charge that battery. Yes, the Volt has a 16 kWh battery, but what you might not know is only 12.9 kWh is used for charging and driving – this is done to extend battery life. 9.6 kWh is used to propel the car and accessories and 3.3kWh is used in the charging process The average cost of electricity in the U.S. is $.12/kWh, so, take $.12 x 12.9 to get a cost to charge of $1.55, a far cry from the $18.56 to charge that I’ve seen some say online. Think about it – if it cost that much to charge, I really doubt we would have 93% of our owners say they are very satisfied with the car.
When that charge is depleted, whether you’re in the Lincoln Tunnel or on a highway, the vehicle switches over to extended-range mode, using a gas-powered motor/generator to keep you going another 344 miles by EPA estimates. When you are in extended-range mode, the EPA estimates you will get 35 city/ 40 highway mpg or 37 combined mpg. With a full tank and full charge, your total driving range is 379 miles.
Some might say “But Rob! You didn’t mention that you have to wait around for it to finish charging before you can take a trip!” Well, no, actually you don’t. If you forget to plug it in, you can still drive the car in extended-range mode until you either refuel (like people have been doing for years and years when they take road trips) or find a spot where you can recharge. You can drive across the country in the Volt in no more time than it takes to use a conventional car.
The other point to factor in is how far your commute will be and that will be different for everybody. What we know is that after 25 million customer miles, their average EV range is slightly more than the EPA estimate of 35 and this computes to an average cost per mile of $.03 - $.06. By comparison, a gas-powered vehicle that achieves a combined 30 mpg costs about $.13 per mile (based on gas prices averaging $3.90 per gallon).
Here’s one example. Let’s say your round-trip commute is 50 miles. In the Volt, you would spend $1.50 for 35 miles of EV range and then $.11143 per mile for the other 15 miles (assuming city driving and the $3.90 gas price mentioned above). $.11143 x 15 is $1.67. Add that to the $1.50 to charge and the cost for that 50-mile trip is $3.17.
Now, if you have a conventional car that gets 30 mpg, the cost for each mile is $.13. The cost for this 50-mile trip would be $6.50 ($.13 x 50). If your car gets 35 mpg, the cost per mile would be $.11143 and the cost for the trip would be $5.57.
So to summarize:
-Average cost to charge the Volt for 35 miles of EV driving: $1.50
-MPG of the Volt in extended-range mode: 35 city / 40 highway or 37 combined
-Average cost per mile so far from Volt drivers: $.03 - .06
-Cost per mile of a conventional vehicle that gets 30 mpg with gas at $3.90 per gallon: $.13
Math is hard, but when used for good, it can also be electrifying.
Note: This blog has been updated with information about the cost of charging the Volt.

As of 1/10/13 we have driven 7175 miles on battery power for a cost of $148 and used 2112 kwh used @ .0699 average kwh cost, and 2096 miles on the gas generator using 56.5 gallons of gas at a cost of $221.85, using premium fuel and getting an average of 37.1 miles per gallon. That breaks down to energy costs of 2 cents per electric mile driven, 10.6 cents per gas mile, and 3.96 cents/mile overall. The car is very economical to operate as a cummuter car and has served us very well. When we go on longer cross country trips the car used is our Camry Hybrid, which averaged 38.5 mpg on a recent trip to Florida and back, at highway speeds which often were at 80 to 85 mph (just keeping up with traffic).

my income is 40K, I bought my volt last January. I have now 6363 mile on my volt for a lift time mpg of 134.
the last 2198 mile i drove, the car used 5.5 gallons of gas. I put $10 of gas in the volt 2 week ago, I have used 1/2 gallon! Before that, I had not bought gas since last july! It cost me 47 cents to charge my volt from my solar panel system. During that first winter I got 35 to 40 mile per charge, this spring, summer and fall I got no less than 49 miles per charge. Now that winter is here I am back to 38 miles per charge. I live in northern Utah, a COLD climate in the winter and a HOT climate in the summer.

My daughter Hillary is on a Volt Demo campaign. Tweet her @HillarysVolt if you would like. While on her way to Dallas she has stopped by to see us. ( Mom and Dad).
So I took a drive. I really like the car and am in the position to get a new vehicle. So I am doing some research into this new technology. One thing I noticed on the instrument panel was "oil life" remaining. It was at 85% remaining. The vehicle has about 3,000 miles on the odometer if I remember correctly. I haven't seen anyone figure in oil changes to their cost analysis.
So now how does that item change the "cost to operate"?
All being fair that should be figured into the cost.
I have two cars and oil and filters aren't cheap! Lets throw in air cleaners while we're at it.
Now I'm going to find out about recommended oil changes on the Volt and see where that leads.
P.S. Hillary just handed me the 2013 Volt owners manual. " The engine oil and filter must be changed at least every two years..".

I dont buy a car cuz I need one, I buy a car cuz I want to. And to compare a japanese crackerbox to a Volt would be like comparing a firecracker to a rocket booster. The Volt is comfortable, quiet, has everything as standard equipment, unlike the imports where the advertised price doesnt include the features found on the Volt. I will be waving to you as I pass up the gas stations. bye bye

Using EPA numbers the Volt on electric mode gets 38mpg equ. To figure energy equ. There are about 115K btu in a gallon of gas, and a kwh is exactly 3.412 btu so you get 33.7kwh = 1 gallon of gasoline. So per the EPA it should take 33.7kwh from you plug to get the Volt moving 38 miles.
I know rates are different all over the country, but where I live in California, it is 16 cents per kwh .16 @33.7 = $5.39 to go 38 miles on the Volt. My car gets 28 miles to the gallon on average so it would take 1.357 gallons to go the same distance. @$4 per gallon I pay $5.43 to go the same 38 miles.
It comes out to a wash - and you need gas prices at their peek to do that.
From an eco point of view though, since you typically charge the Volt at night when power utilities are dumping unused power* - there is actually no additional pollution costs to run the Volt.
*Utilities can't shut down their base-load generators, they always must run at a constant rate so they can provide for the high use daytime period.

2) technically, it seems that many or all ice vehicles have an engine far larger than is required for the average power required. This seems necessary for safe passing, normal safe traffic acceleration and just plain desirable driving feel. Surely the key to the hybrid technology is to allow the lower average output of a a very small, cheap and ultra-efficient ice, to be supported at times of power need or want, by the electric motor and battery accumulated energy? Future refinements will make more use of this fact, perhaps when all the crazy emotional arguments and vested interests calm down.

Do you really think it’s going to be worth $27,000 in 7 years ...................condition and you think a Volt, with its battery almost out of warranty is going to be $11,000 over that. And you think a Cruze is only going to be worth $2,500.....
Your number a off.
You are forgotting that a Chev Volt has 2 power sources. When its 10 years old and been run mostly on electricy you still have an almost brand new ICE with very littte milage on it. Even if battery is worn out it will still run just fine on the ICE thats almost new and with just the almost new ICE it will get better milage in city than your 10 yr old Cruze, (25 city EPA Cruze vs 35 EPA Volt), which will need a new engine by now.
Sorry but the VOLT will be woth lots more than a Cruze that need a new engine.

My electricity rate is only 9.6 cents (.096) per kWh and it will drop to 9.2 cents next month when my new contract kicks in, so I am very satisfied with the cost involved while charging the battery. I also do not have my 240 station in service yet at my home. It is due to be installed in the next couple of weeks. My roundtrip to work and back is 33 miles and is well within the range of the Volt.
When I rolled off the dealer lot on March 3, 2012, it had a full tank. I have used 1.3 gallons since that time and my odometer is showing almost 868 miles traveled. I'll take that kind of mileage ANY DAY OF THE YEAR.
All of these comparisons to other fuel efficient cars is missing the mark it seems to me. From my perspective, it is much more relative to compare to a car that you would consider purchasing. I would have never considered purchasing a Chevy Cruze. It does not have all of the things that I WANT in a car. Therefore, I compared my Volt to an Acura TL 2012 model. Price-wise, I came out ahead and very much ahead on fuel economy.
Now I did pass along some ideas for upgrades: 1) upgrade the cruise control to like the adaptive cruise control in the new Acura's and 2) use the sensors embedded in the bumpers to alert you when there is another car in the lane next to you: blind spot notification. These two items and you would be on-par with the Acura. Everything else is there already.

Mr. Peterson's blog gave a national average for cost of a kWh:
"The average cost of electricity in the U.S. is $.12/kWh, so, take $.12 x 12.9 to get a cost to charge of $1.55."
Here's my data from LA DWP:
Energy Charge - per kWh during High season(June-September)
High Peak Period $0.16061
Low Peak Period $0.08144
Base Period $0.04655
Electric Vehicle Discount - per kWh ($0.02500)
According to LA DWP: The "Base" hours are 8:00 p.m. – 10:00 a.m. weekdays, and all day Saturday and Sunday. In other words, nighttime electricity use costs $.04655/kWh. Subtract the EV discount of $.02500 from the base period and you get $.02155/kWh. Multiply that by 12.9kWh to charge the Volt and you get .277995, or approx. 28 pennies to charge the Volt overnight in LA during the peak season.
Let's say you get 35 miles to a charge. The cost of 1 mile in this scenario is $.00794, or 8/10ths of a penny.
During off season the base period is actually a little more money, but to charge the Volt overnight is still approx. 33 pennies. A mile in this scenario is still under a penny.
If you drive using only electric, you're going to spend about $10/month to power your vehicle in LA and virtually nothing on gas. I average 20 miles of driving a day, well under the Volt's range. This car is certainly a good deal in terms of cost of fuel, particularly when gas prices are so high.
My advice to prospective buyers is to take a close look at how you use your current vehicle. How far do you drive every day? How often do you take long trips? The Volt dramatically loses its value if you use the gas component for more than half of your driving. Take a look at http://www.voltstats.net for actual unadulterated numbers downloaded from the Volt owner's Onstar systems.
Are you in the market for a car in that price range? There are plenty of cheaper options that offer great mileage, so the Volt may not make financial sense for you to purchase at this time(3/25/12). It may, however, make sense to look into their lease program, which is reasonably priced.
Good luck, and I hope this helps!

I can always recharge to go more than 35 miles in a day.
A lot of businesses are installing 240V charge stations for their employees to use at work. 240V charging takes about 4 hours, so if I need to go 35 miles to work I can then charge 4 hours, drive 35 miles going to lunch, charge another 4 hours and drive 35 miles home. 105 miles in a day gas free.
The current record on VoltStats.net is 254.45 Miles in one 24 hour period, all on electricity, no gas. That was a stunt of course, to prove it can be done. "
You are the exception not the rule. Most business don't have a 240 recharging station.
254.45 miles in ONE day. Let's see I did over 250 miles in less then 4 hours went to a Dr. appointment ate lunch and drove back back all in less then 9 hours. I have to do this every threes months so it's not a stunt. I can do that every day, day in day out. And my recharge time was less than 10 minuets.
I have also noticed most of the comparisons are to cars that are much bigger than the Volt.
"written by feerbmeh,
Assume used price on Volt in 7 years, $27,000.”
Do you really think it’s going to be worth $27,000 in 7 years heck a 2005 Cadillac STS had a sticker price from $40,000 to 47,000 and a used car price today of $16,000 in excellent condition and you think a Volt, with its battery almost out of warranty is going to be $11,000 over that. And you think a Cruze is only going to be worth $2,500 when a 2005 Toyota Corolla CE Sedan 4D Mileage: 75,000 is over $10,000?

Eric Bolling with Fox News doesn’t understand electric cars, batteries, and electricity fundamentals. He also doesn’t know how to fact check his articles or apply basic math. One of the biggest challenges with electric vehicles is that most of us are still learning about them. Inaccurate information does not help anyone make an accurate judgement about any technology. I like FOX news and appreciate how they balance out other news channel reporting, but they hurt their own credibility when they do grossly inaccurate reporting.
Here’s a few corrections to the below article.
1) The Volt has a 16 kwh (thousand watt hours) battery NOT “16 Khz”. Here’s an example of what 16 kwh represents: 16 kilowatt hours would be equal to 160 each 100 watt bulbs burning for 1 hour (160 bulbs X 100 watts X 1 hr = 16,000 watt hours = 16 kwhs) or 80 each 100 watt bulbs burning for 2 hours (80 bulbs X 100 watt bulbs X 2 hours). The typical home’s electric usage averages 600-1000 kwhs per month. The battery pack stores 16 kWh of energy, but, says GM, not all 16 kWh are used. A full charge adds 9.6 kWh that can be used to move the Volt and another 3-4 kWh are used in charging on a 120-volt system, less with a more efficient 220-volt charger. So a full charge on 120V power consumes 13.4 kWh
2) Kansas City Power and Light charges (http://www.kcpl.com/About/ratesOverview_KS.html) $.09469/kwh during the summer and $.07312/kwh in the winter NOT “$1.16 per kHz”.
3) Using the KCP&L rates it costs $1.27 (13.4 kwhs * .09469) to fully charge the battery in the summer and a $0.97 in the winter NOT ”$18.56”. Conservatively you’ll be able to drive 30 miles on the charge, unless your FOX news. It would cost $4.50 in gas to drive the average mid size vehicle 30 miles (the average regular unleaded gas cost in KC today is $3.60/gal and a mid size gasoline engine will have a combined fuel mileage of 24 mpg).
4) Most drivers will get 25-40 miles with a fully charged battery dependent of driving patterns, driving habits, highway/city driving, or if you’re a news reporter that needs to sensationalize the results to get a listening audience NOT 25 miles.
5) The Volt plug-in hybrid electric design is more suited for folks who want to use it as a commuter vehicle NOT for folks who take frequent “14.5 hour” “road trips” or longer daily commutes over 60 miles. The average driver drives 13,500 miles/year or an average of 37 miles per day. The average daily roundtrip commute to work is 32 miles. Age 65+ average miles driven per year is 7700. What Chevy is doing is designing a vehicle whose battery will support the average driver. They are doing this because larger capacity batteries would not be worth the extra cost and an engine could extend the driving range.
6) An average North American mid-size gasoline only engine car travels 21 mpg (US) (11 L/100 km) city,
27 mpg NOT “35 mpg”.
7) Based on several impartial driver tests the Volt averaged 30-33 mpg on a depleted battery NOT 30 mpg including the fully charged battery. The engine is just there to allow drivers to occasionally take longer trips (see bullet 5).
8) The average Volt costs closer to $38,696 (google) (excluding the $7,500 federal incentive) NOT $47,000. A quick google search indicates the average mid size vehicle cost ranges from $20,466 - $28,615 NOT $15,000. Just like a Corvette or $40K SUV, the Volt currently does not make financial sense for most folks. These early adopters choose to pay more for a Volt because, just like the Corvette and $40K SUV driver, they have their own reasons and its their choice. The costs for electric vehicles will decline as markets develop (due to the early adopters and incentives) and battery technology and hybrid electric technology continue to improve. As demand increases there will continue to be supply system challenges that will occasionally put upward price pressures on electric vehicles. Just like the silicon shortage for solar panels, steel costs for wind turbines, and concerns about lithium availability for batteries, suppliers and technology developers will figure out how to respond to the demand with new or alternative supply sources. Similar to solar companies, solar technologies or any technology, some EV related companies and some EVs will fail while other will eventually excel.

A response on a GM blog was right on target when it started by quoting mathematician and ex-Dartmouth College president John Kemeny: “The man ignorant of mathematics will be increasingly limited in his grasp of the main forces of civilization.”

10,000 miles per year /19 mpg (avg v6/V8 engine) = 526 gallons times $4.25 (assume for next 7 years, probably will
be much higher in reality) = $2,236 per year times 7 years = $15,765 SAVED on gas.
Volt price $42,000 - $15,765 gas = $26,235. $26,235 - 7,500 rebate= $18,735

Cruze price $22,000 + $11,900 gas = $33,900. $33,000 - 0,000 rebate= $33,900

One thing I've noticed is that I get about 35 mpg when I am on the generator on the freeway doing about 75 mph. I do better on surface streets getting almost 45 mpg on the generator in stop and go due to the regenerative braking, etc. However, I almost am never on generator. I am able to use the battery 90% of the time, and the other 10% is usually for extended business trips. We got it in November in Michigan, and got as much as 45 miles on a charge. Temps below 25 deg. F. brings it down to just under 30 miles.
I absolutely love how the car drives! My husband bought it for himself because he could go back and forth to work on battery. I work farther away, but my company got a charging station and with gas so high, I get to drive it now. He is not getting it back!!!

This is for 120V charging right? The one that takes around 10 hours to fill a battery from "empty"? Sure, that's what most people understand, and will most likely use.
I think it would be good to add that 240V charging only takes 4 hours and is more efficient since the losses occur for a shorter time.

1. Not one muscle car on the rode was purchased because the owner needed the extra power. Why not enjoy the “extra technology” in the Volt, to justify the difference in costs.
2. The performance is great.
3. Most drivers can literally get to work and back without ever having to buy gas. Even if you drive farther than the battery charge, the extra gas needed is very small. This is very empowering, in the effort to reduce our dependency on oil (and the countries we are forced to buy it from ).
4. No matter what the planet ends up going to in the future, wether it be hydrogen, solar, wind or even if we continue with hybrids, we will have to keep improving the batteries, electric motors and control systems. Buying the Volt encourages these technologies which will bring the price down for everyone.
5. In the end, the price of hybrids will be affordable to everyone. This is the future, and if the US doesn’t do this, other countries will. And don’t forget, the day gas prices sky rocket people will be fighting each to get their hands on a hybrid.

If you are a prospective buyer looking at volt here is a simple way to find out if Volt is your car financially. If you drive less than 30 miles a day 80% of the days then it is a good car for you. One caveats to this - if you live in a colder area you might get only 25 miles on some days. Lowest I have gotten is 28 EV miles to date but this year our winter day time temperature has not dropped below 0 either. Another thing that made a big difference for me is 240V charger. This pretty much reduced my gas consumption on the weekends to zero because I can now charge couple times in a day if I have to.
Hope you guys find this useful. Either way once you drive an electric car you will not go back to gasoline car. Feels very 20th century....

I can't think of any other cars that can get 35 mpg in city driving. Sure they get it in hightway driving, but not city.
Even if you never charged the battery this is excellent mpg. Can the Cruze get 35 in city driving??
written by Jay Hennigan, February 26, 2012
With the Volt, electric and gasoline fuel sources are a logical OR. You don't need to ever plug in the car and you can fill it at gas stations like a conventional car if you like. Similarly, if your travels are such that you drive less than 30 miles between charges, you can use just electricity and never buy gas. The battery management system is very intelligent. The Volt always maintains sufficient charge to spin up the gas engine even if the battery shows "empty". There's also a small 12-volt battery for the lights and electronics separate and apart from the battery used to move the car. If you have a dead 12-volt battery from leaving accessories on, you can jump-start the Volt like a regular car. It's actually a lot easier than a conventional car because you don't need to directly crank the gas engine, just boot up the car and then the motive battery will spin up the gas engine if needed.
Most of the public charging stations are free to use. A small percentage are located in paid parking garages where you pay the regular parking rates but nothing extra for the electricity. Often just the opposite, cars park for free while charging. Another advantage is that the EV charging stations are usually very close to the business, typically next to the handicapped spots so the parking is often more convenient. It's a win-win for the business and/or the business district. EV owners, especially those without the Volt's range extender, will stay a while and spend money at the business. A mall, restaurant or movie theater with an EV charger is likely to attract customers who will pay to shop, eat or see a movie while charging (for free).
There are a very few public charging stations that require payment for use, and it typically is per hour or per use as opposed to metered electricity. Most states require those selling electricity to be regulated utility companies so that's another reason so many of them are free.

In addition, the Volt is just plain an awesome car to drive.
As far as the math, one thing that people haven't mentioned is that maintenance costs on a Volt are far less than a conventional gasoline car. You'll likely not need a brake job for well over 100k miles due to regenerative braking. I've got 12K miles on my Volt after over a year and haven't needed an oil change, nor will I for quite a while. Display says 46% oil life remaining. The same applies for everything else associated with gasoline engines. Mufflers, water pump, valves, etc. just don't get used nearly as much and will last many more miles. In my case over 80% of my mileage is electric so the gas engine and all of its related parts will last about 5 times as long, probably more as the RPMs are held at the sweet spot, no idling, etc.
If your electric utility offers time-sensitive metering and you charge at night, you'll pay about five cents per kWh, so figure about 1.25 cents per mile.

Second.... there is much misinformation out there about electric rates. How much do they charge at these 450 charging stations around the country? Is this where someone is getting this figure of well over $1.00 per KWh? I assume it will be considerably more than the 10 to 12 cents I pay at home..... before all the delivery charges and such are added in.

Good point - we updated the post with some information. 12.9 kWh is used for charging and driving - 9.6 kWh is used to propel the car and accessories and 3.3kWh is used in the charging process. With $.12 per kWh, that would be about $1.55 to fully charge - I see your own rates are a little above that. Thanks!

Go to the Volt web site, check out the Volt FAQ and take a look at note #6 which states:
(6) Based on national average of 12 cents per kWh and 12.9 kwH for a full charge ($1.55).
Another error in your numbers (and the numbers in not 6) is the cost for electricity. While the electricity cost may say $0.12 per kilowatt hour (kWhr) there are delivery charges that are based on how many kWhrs are used. Example: Looking at my power bill it shows that I pay $0.109 for electricity, however my total bill (with delivery charges included) shows I pay $0.174. So it costs me 13 x 0.174 = $2.262 to fully charge my Volt.

1. High Tech Car
2. Very fun to drive
3. Better looking Car
4. The money I spend on the Car stay in the US and reduces demand of Gas/Oil for everybody
Thats my math.
It just make sense to get a volt if your looking for a new smaller sedan luxury or economic.

For those who talk about the cost of the vehicle, and how many miles it takes to justify the expense... again, look at the monthly cost for the lease.... and again, compare to a car you used to drive a few years back. I used to drive a Jeep Wrangler Sahara V6 that got 9mpg due to modifications to the vehicle... it was a $35,000 Jeep - 15 years ago! I drove 2000 miles a month - let's say I was still driving that car and gas was $3.599 a gallon - that's $799.78 a MONTH on gasoline, plus I still had a car payment of $485/mo to pay!!! Now I drive a Volt at $349/mo and pay nothing for gas. Well, okay, I have used 0.5 gallons over the past 900 miles of driving... I hate to admit that... so that's $2 compared to $800.
This should be the Volt commercials... two columns.... Ben and his cars... Jeep vs Volt - holy crap I spent so much money on driving back then!!!!

I don't deny that the Volt > Gas power cars on running costs. Where I struggle is the cost difference to purchasing the Volt over the gas power car. 41,000 is significantly higher than the 23-25k gas powered cars. Yes there's that 7,500 but it's a tax credit so you have to pay your taxes and fees off that 41k first then you get your 7,500 later. It helps, but doesn't help enough.
The only way I've gotten the volt to come ahead financially is to take a 10 life of both volt and a gas power car. Assume the batter doesn't need to be replace and doesn't reduce in capacity. Then if gas was 6.90 for the 10 year period - the Volt wins... barely.
Which is sad. I would love to buy a volt. I wan to drive a Volt. I just can't financially rationalize buying a volt.

I just read all of the comments and the one thing they have in common is all the naysayers DO NOT OWN A VOLT.
I DO OWN A VOLT.
I bought it because I wanted the latest technology and to play with it. Cars are fun and exciting to own. I didn't buy it to save gas, just as I didn't buy my Lexus 430 to save money. I bought it because it was the BEST. The VOLT is the best eCar.
I find the VOLT to be equal to the LS430, leather, electronics, performance and only slightly smaller.
The Lexus hardly ever moves and I can't keep my wife out of the VOLT. That's GOOD.
We save the miles on the 430 and save 1000 mi./ 20 mpg = 50 gallons x 3.69 = $184.50 per month
My eMPG is currently 125 mpg. Still on the first tank of gas after two months,
I AM STUNNED.
