Skip to comments.A Chevy Impala That Goes 500 Miles On A Tank? With Natural Gas, It's Possible
Posted on 10/17/2013 6:06:17 AM PDT by thackney
Capitalizing on Americas abundant supply of clean-burning, low-cost natural gas, General Motors said Wednesday it will build a Chevrolet Impala sedan that can operate on either gasoline or compressed natural gas and travel up to 500 miles between fill-ups.
The bi-fuel Impala, which goes on sale summer as a 2015 model, could be the start of something big. Honda Motor has been selling a natural gas-powered Civic since 2011 and while still modest, sales have been steadily rising. The Japanese carmaker is on track to sell about 2,500 CNG Civics this year, up from 1,900 in 2012 and 1,200 the year before. In July, Ford Motor said its most popular vehicle, the F-150 pickup, will be offered with a compressed natural gas engine starting in the 2014 model year.
Natural gas will grow increasingly attractive as an alternative fuel source, as weve seen each year with natural gas Honda Civic sales, particularly in areas like California where HOV lane access is available, said Alec Gutierrez, senior analyst for Kelley Blue Book. The lack of infrastructure remains a hurdle, but if more automakers begin to offer CNG-powered vehicles, we could see a greater push for access to CNG in the years to come.
The Impalas bi-fuel powertrain is engineered to switch seamlessly from CNG to gasoline, which should reassure consumers worried about finding a place to refuel. For business fleet customers, whose drivers return to a central location, CNG refueling shouldnt be a problem. GM did not announce the new cars price, which is likely to be higher than the standard gas model, but savings at the pump could offset that extra payout quickly.

And in an accident it will break into 500 pieces and go 500 feet in every direction.
Already well underway. I know a company that is doing quite well converting commercial fleets to run on LNG. Between the lower cost and the cleaner burn, resulting in less engine wear, the ROI is pretty dramatic.
Not the first time this has been done, of course. My BF has two bi-fuel Chevys, both Cavaliers, from the early 2000s. They were commonly used as fleet cars for government agencies, but I guess they proved impractical at the time and were auctioned off.
The computers regulating the natural gas switchover in his cars went bad long ago, so now he just runs them on regular gasoline.
Yeah....really believable - from the people that brought you the destruction of free-enterprise, legal interest in financial assets, pandering to Unions and their medical plan, et al....
They lied, LIED about Volt’s efficacy, its financing, its value, its performance - everything....Just because you slap the name “Impala” on it ain’t gonna cut it this time, GM. Choke on your cars and trucks.
This is easy to do, they just make the fuel tank larger.
I could build one that could go a thousand miles, but wouldn’t have a back seat, and the springs would have to be stronger.
We have been using compressed natural gas for decades in highway vehicles. The crash test data, and actual crashes, proves your made up claim false.
Carbon fiber tanks designed to withstand 4,000 psi or more are quite strong and don't shatter.
And in an accident it will break into 500 pieces and go 500 feet in every direction.
These pieces will go in excess of 500 MPH. I had a 79 Vega that got 35MPG at interstate speed limit. I often stopped to get gas just to stretch my legs and get something to drink. 500 miles in one setting is cruel and usual punishment.
Is CNG safe?
The answer to this is, unequivocally, yes CNG is a safe form of energy. However, there are many myths out there regarding the dangers of CNG and we would like to discuss those here. For a visual demonstration of just how safe CNG is, please check out these three videos: (at link above)
Gun Test on Natural Gas Tank
Dynamite Test on Natural Gas Tank
Severe Abuse Test on Natural Gas Tank
VW made a splash with the Passat turbodiesel, able to do 700 miles on one tank of fuel. Perhaps jealous, Mercedes has recently introduced the E250 diesel, a sedan that can travel a bladder-busting 800 miles on a single tank.
A 1997 to 2001 Camry 4 cylinder will go 600 miles on a tank. 41 MPG at 75 MPH. I have done it many times. The newer ones are too heavy and have too much frontal area to do that good.
Back in the early 70s, when the oil embargo hit, GM began working on a 40 gallon gas tank for the full size cars but the govt put the kibosh on it.
That is part of the CNG price as it is sold. Just like we don't need to discuss the cost of refining crude into gasoline, the cost is built into the price of the fuel.
Ok, the green liars lied about the volt.
Being conservative does not mean hating green if it makes free market sense.
Note: Honda has been making, selling, and profiting from a CNG Civic for a couple years now without any subsidies.
No one mentions it because it is of course included in the price you pay.
The other advantage to CNG that no one every mentions is the storage of it. Typically around here when a gas station needs to replace their gasoline storage tanks the company goes out of business. Replacement of the tanks is very expensive. IF a gasoline storage tank ever leaks, it becomes an EPA superfund site. The owners of the station almost always end up declaring bankruptcy. If a CNG tank ever leaks it then just vents into the atmosphere.
I agree CNG is a good option. However, the last company in existence that could do it justice is GM. They should starve and go out of business.
I guess you could say that Dynamite, Black Powder and Nitroglycerin are safe also. It is a relative statement. I don’t want to hunt down a place to get high pressure natural gas just to drive a car. It is a risk and hassle that I am not ready to take. Why not get gas prices back under $2.00 a gallon and leave the exotic fuels to the hobbyists. Rational fuel prices would expand the economy greatly and give freedom of travel back to the people.
My 2005 E320 CDI regularly goes 600 miles on a tank, plus or minus. In mixed driving, I average 30 mpg, but on one roundtrip from the Annapolis area to Ocean City, Maryland, I got 40 mpg, even with stop-and-go traffic in the Easton - Cambridge area, at speeds of 65 mph - 75 mph.
LNG is not going to be economic for consumers like you and I. It works great for fleet service or long-haul trucking. But the need to either keep the engine running or the tank temperature below -260°F after a few days of non-use is not going be an economic solution for a daily driver.
Wishing will not make it so. Pretending that the cost to produce oil in the shale fields is no different than older conventional fields won't make it true.
You should google all the suppliers from fuel lines, fuel injection and the tankage involved. All the certified retrofitters meet all the Govt alphabet soup certifications, but you should look into the tanks for CNG made out of spun and welded aluminum rapped in Carbon-Fiber/Graphite, that meet all crash requirements...
What? I don't think you've done much research into this, have you? There's no refrigeration on LNG tanks.
At 28 mpg, my Impala is getting 400 + to the tank now.
Stories like this with insufficient information (no, I have not bothered to read the full article about a GM vehicle) are like the friend why says,
"My car gets GREAT gas mileage!"
"Really, how much?"
"Well, I filled up last Friday and am still showing a quarter tank remaining!"
Insurance companies that evaluate cost and risk have figured out that CNG is safer than gasoline.
Data collected over time has demonstrated natural gas vehicles to be safe in actual operation. Based on a survey of 8,331 natural gas utility, school, municipal and business fleet vehicles (NGVs) that traveled 178.3 million miles:
The NGV fleet vehicle injury rate was 37% lower than the gasoline fleet vehicle rate.
There were no fatalities compared with 1.28 deaths per 100 million miles for gasoline fleet vehicles
the sad part being, of course, that by law Ugandan gas stations are 1,000 miles apart
You can probably get around that one.
Has anyne tried a car gas turbine yet?
As for as the tank exploding in a collision,I have to call Bull Crap. This ain't 1935. Some fear mongers
sound a lot like today's crop of civil rights activists who are stuck in the 1960s
There's no refrigeration on LNG tanks.
No. The insulated tanks must also be designed to withstand the increasing pressure for a typical span of 5 days. After that point, they start venting fuel if nothing else is done to reduce the temperature. This is not going to be acceptable in a residential environment.
No it could it not. I didn't realize CNG had that kind of costs savings on a doller per mile traveled basis.
A compressor must be used to put the gas into your car while parked in your garage. The compressor cost $10,000 and takes 8 to 16 hours to recharge the tank depending on tank size. No one ever mentions this little detail about CNG vehicles.
I just re-read some of your posts and you are right on in your support of LNG. However, you are confusing LNG with CNG when talking about low temp tanks. Sorry if my last post was snarky but I thought you were the one poo-pooing LNG.
Competing projects propose $500 home CNG fueler
They fill overnight. Also most people don’t drive 500 miles every day.
In good conditions, my GMC Duramax can go 500 miles on a tank. In perfect, 600 miles. On straight #2 Diesel. Diesels are easy to convert to CNG.. Add the tank, control system (regulated by boost pressure) and a nozzle in the intake to fumigate the intake with CNG. The kit is very affordable. I considered doing the conversion but the tall pole in the tent was a place to fill the CNG. I have natural gas in my house, but the pump cost $15K last I checked and had to be rebuilt every 40 hours of use. The only other places to fill the CNG around me were municipal filling stations.
That can be worked around, by doing the thing modular. Keep two tanks, one being always recharged. Load charged tank instead of charging the car.
How big a tank?
They lost me at “chevy”.
You left gasoline out of your dangerous materials list.
I saw sometimes 20 full propane tankers on the railroad going though the campus at Colorado State University. Each one was capable of wiping out a radius of one mile.
The Russians have a bomb that weighs about 30,000 pounds and uses fuel for its explosive. It is a “Fuel Air Explosive” device which is their largest non nuclear device.
You can buy a lot of diesel for $15k.
The original manufacture of the Phill home CNG unit went out of business, mostly due to their quality problems and poor reliability many years ago. The rights to the name and product were purchased by BRC, a commercial CNG refueling manufacture.
The housing may look similar, but it is a far better unit and should be closer to $5,000 installed unless you have other onsite issues.
Also, depending on where you live, more CNG commercial stations are opening up.
Natural Gas Fueling Station Locations
In some locations, lease option of the compressor is also available.
Well, crap. I’m the one confusing the two. Sorry.
