    Automakers are throwing a fair number of alternative fuels in a effort to improve mileage and emissions to see what sticks. General Motors announced this week that they are introducing Bi-Fuel Impala that will be available to fleets and consumers starting next summer. The company points out that the Impala is the only manufacturer-produced, full-size bi-fuel sedan in North America.

    The Bi-Fuel Impala can run on compressed natural gas (CNG) and gasoline. The vehicle features two tanks for the fuels and has a total range of 500 miles. The driver can change from CNG to gas and vice versa thanks to a button on the dash.

    We'll have more details on the 2015 Bi-Fuel Impala when we get closer to summer sale date.

    Akerson Announces Bi-Fuel Chevrolet Impala Sedan

    2013-10-16

    -GM to offer only manufacturer-produced full-size bi-fuel sedan in North America

    -Designed to capitalize on plentiful clean, domestic natural gas

    -Will be sold to retail and fleet buyers as a 2015 model

    -CEO repeats call for consumer-driven national energy policy

    WASHINGTON, D.C. – General Motors will build a Chevrolet Impala sedan for retail and fleet customers that operates on either gasoline or compressed natural gas (CNG), GM Chairman and CEO Dan Akerson announced today.

    It is the only manufacturer-produced full-size bi-fuel sedan and expected to go on sale next summer as a 2015 model. Akerson announced the car during remarks at an energy summit marking the 40th anniversary of the OPEC Oil Embargo.

    "OPEC Oil Embargo + 40: A National Summit on Energy Security," was sponsored by the nonpartisan group Securing America's Future Energy, or SAFE. Prominent political, business and military leaders assessed the current state of America's oil dependence since the 1973 oil embargo

    Akerson said the bi-fuel Impala is an example of using affordable technology to reduce oil consumption and save consumers money at the pump.

    "We know that U.S. energy security won't come from a one-off moonshot," Akerson said. "It will flow from our systematic investment in technology and innovation... our drive to get more from existing energy sources and renewables... our commitment to conservation... and it will be assured by fully and safely exploiting our shale gas reserves."

    Natural gas is a cleaner-burning transportation fuel compared to petroleum products, and costs significantly less than gasoline at current prices. CNG vehicles typically have 20 percent fewer greenhouse gas emissions than gasoline-powered cars, according to the California Air Resources Board.

    The Chevrolet Impala bi-fuel sedan addresses the range anxiety issue associated with vehicles that run only on natural gas, Akerson said. It features a factory-engineered and fully warranted powertrain that switches seamlessly from CNG to gasoline. Total range is expected to be up to 500 miles.

    Akerson said that in addition to advanced technologies and alternative fuels, achieving energy security will require productive partnerships between energy companies, utilities, environmental groups, labor unions, universities and manufacturers.

    GM, he said, is working closely with 14 of the country's largest unions and environmental groups through the Blue-Green Alliance, and has relationships with regulators that are "more constructive than ever."

    Akerson also reiterated a call he made earlier this year for the Administration and Congress to create a new, consumer-driven national energy policy from a position of strength and abundance.

    For its part, GM is committed to saving 12 billion gallons of gasoline in its 2011 to 2017 model year vehicles – offsetting nearly a year of crude imports from the Persian Gulf – with technologies that include lighter materials to reduce vehicle mass, alternative fuels, clean diesel and electrification.

    In addition to the Chevrolet Volt, Chevrolet Spark EV and the upcoming Cadillac ELR, GM is introducing start-stop technology standard on the 2014 Chevrolet Malibu helping the midsize sedan achieve 25 mpg city/36 mpg highway, and using electrification to boost fuel economy in the Buick Regal and LaCrosse sedans, which both get EPA-estimated 36 mpg hwy.

    "Akerson also reiterated a call he made earlier this year for the Administration and Congress to create a new, consumer-driven national energy policy from a position of strength and abundance."

    Sounds like one of the smartest things I've heard him say. It doesn't work when it comes from the top down, it must come from the bottom... up. CAFE sucks!

    At the Seattle auto show, they made this announcement which drove considerable interest and questions. One thing that was different than what is stated here is that the system would be auto switching between the two fuels. So I am wondering which is correct the manual change over or the auto change over?

    Computers today allow the CNG Conversion kits to seamlessly move back and forth between the two fuels. I do not see why GM would go with a manual system. I have to think this is a mistake as the folks at the Seattle Auto Show said it was a auto system that would go back and forth between the two fuels. Seamless driving up to 500 miles.

    As someone who knows absolutely nothing about CNG autos, why would it switch between the two? Why wouldn't it burn the CNG and then if you do not fill up, at that time, switch to gas?

    I may be totally missing something, as I said I have no knowledge at all about CNG as a fuel source for cars.

    May be auto-switching with manual override?

    The benefit of having an auto switch system which you have with Versus conversion kits or others out there is that you run on the fuel you are currently burning and when your tank is empty it seamlessly switches over to the other gas and continues to run. No stopping, dying of the motor with a manual change over switch. This way you just drive the auto and it can move back and forth between CNG / Petrol depending on which tank is currently full for use.

    • It started with legacy OEMs trying to build and sell electric automobiles over the last 100 plus years. It took Tesla to actually grab the attention of the public and now with Rivian, GM, Ford, Kia, Hyundia, VW and so many others, we now see almost every day EVs driving all around the world. There is no doubt the future will be electric, yet the state of electric fast charging is for some a hinderance to buying an EV as vehicle purchases are one of the largest decisions households make other than buying a home. The federal government has started to release funds for installation of a nationwide network of Fast charging stations. We currently have Tesla's Supercharger network and Electrify America charging stations with more opening up monthly across the U.S. Both networks cover major national highways and state routes, yet the current state of access leaves the country in a nation of disconnected charging access in regard to road-trips. Let's start with first understanding the Bipartisan Infrastructure Law, enacted in November 2021 which approved $7.5 Billion dedicated to EV Charging. This is split into two funding pools:  $5 Billion for National Electric Vehicle Infrastructure (NEVI) program $2.5 Billion for a discretionary grant program to tackle rural charging and underserved and/or disadvantaged communities $5 Billion NEVI program Two prong approach is that these funds will be used in the deployment of approved state-proposed EV charging infrastructure and the formation of an interconnected network to facilitate data collection, access and reliability. The first part is split over five years, the first part being a $615 million disbursement for 2022 and an estimated $885 million for 2023. This program required each state to submit plans to the federal government, laying out where the EV charging stations would be, these are a minimum of four 150-kW DC fast-charging units, every 50 miles. Today, all states have submitted plans and are approved. In the past months leading up to approval by the federal government, states had to create a very detailed plan that included working with the federal government to fine-tune each state's plan that covered charging routes that are also designed Alternative Fuel Corridors. Those that would like to see the plan for their state can do so at this joint state/federal website. State Plans for Electric Vehicle Charging · Joint Office of Energy and Transportation (driveelectric.gov) In total, 75,820 miles of interstate/Federal highways have been designated Alternative Fuel Corridors as of July 2022. Thanksgiving is upon us, and the Energy Department's Alternative Fueling Station Locator map has been updated to now cover Ready and Pending EV Corridors. You can check the actual stations by clicking on the Station Location check box. FUEL CORRIDORS The Map allows you to zoom in and out to get better details of corridors near you. Alternative Fuels Data Center Map is as of November 2022. You can clearly see dark green for ready and lite green for pending corridors.  Most useful is the pending corridors so one can make choices about road-trip routes. Looking at specific state plans will give you an understanding of how soon each corridor will be built out. The bulk of the identified corridors will all be built out by mid-decade. It is understandable that significant gaps will still exist. These could be covered by private businesses and or will fall under the rural planning. The benefit is that this is a glance into the future for those needing fast-charging stations for road-trips. Tools The alternative Fuels Data Center has a large selection of helpful tools that cover calculators, interactive maps, data searches, fuel providers and more to assist with making a wide range of decisions. Alternative Fuels Data Center: Tools (energy.gov) Here are just a few of the tools afdc provides for us to include in the websites for ease of use. <iframe src="https://afdc.energy.gov/widget/calc/" style="height: 372px; width: 250px; padding: 0; margin: 0;" scrolling="no" frameborder="0"></iframe> <iframe src="https://afdc.energy.gov/widget/calc/Electric" style="height: 372px; width: 250px; padding: 0; margin: 0;" scrolling="no" frameborder="0"></iframe>   Alternative Fuels Data Center: Alternative Fueling Station Locator (energy.gov) NEVI - Environment - FHWA (dot.gov) Alternative Fuels Data Center: National Alternative Fuels Corridors (energy.gov) Alternative Fuels Data Center: Station Data for Alternative Fuel Corridors (energy.gov) View full article
    • So again...   You CANNOT sit here and praise the tire in one post and then go "well, just get another tire" when it is proven that said tire actually worthless for off roading and worthless towards your argument. FFS

    • If you don't like Pirelli Scorpion then buy something else, someone paying $350k for a car can get a different set if they go off road and a set for on road. Point still is, where is the off roader from Genesis, BMW, Audi, Cadillac, etc?  None of them are there, Audi is killing the R8 this year, none of them are making sports cars or super cars either.   And according to Car and Driver, none of these Genesis X concepts are seeing production.
    • Joke of a HYBRID Tire, per their own web site: The Pirelli SCORPION™ ATR is a versatile hybrid on / off road tire for use on a wide range of highway and off-road applications, designed to provide confident braking and handling. ... Download the brochure and learn more SCORPION™ ATR tire warranty. ... SCORPION™ STR SCORPION™ WEATHERACTIVE™ So lets look at a review that I found to be consistent across tire reviews and for which @ccap41 clearly pointed out. This tire is really just a street tire that they also are trying to say is off-road all terrain and it FAILS. Pirelli Scorpion ATR Tire Review | CarShtuff QUOTE:  How Does the Scorpion ATR Perform on Ice and Snow? When it comes to ice-covered or snow-covered roads, the Scorpion ATR doesn’t perform to the level you would expect. As much as it may deliver some usable traction in ice and snow, you will have to drive extremely slowly in these conditions. If you drive fast, the vehicle may swerve off the road, due to the tire’s poor traction. Simply put, it lacks the level of traction needed to deliver safe driving in snowy and icy conditions. So, if you live in an area that experiences heavy winters, then the Scorpion ATR is not the right choice for your vehicle. Instead, you should choose a dedicated winter or snow tire.   It’s important to note that the Scorpion ATR is not specifically engineered for serious off-road conditions. It lacks some key features and technologies that you would find on a dedicated off-road tire. So, if you consider yourself a rugged off-roader, then the Scorpion ATR may not be the best choice for your driving needs.
