GM One Of The Worst Car Companies In The U.S. For Fuel Economy

GM is in the midst of a pivot to all-electric vehicles and sustainable energy practices, with plans to launch 30 new EV models globally by 2025, eliminate tailpipe emissions from its light-duty vehicle lineup by 2035, and reach carbon neutrality by 2040. However, in the meantime, a recent government study indicates that GM is one of the worst auto companies in the U.S. with regard to fuel economy.

According to the recent 2021 EPA Automotive Trends Report, GM’s average estimated real-world fuel economy increased from 22.2 mpg in 2015 to 23 mpg in 2020, placing it near the bottom of the list when compared to the rest of the automotive industry.

Ford tied with GM in terms of current real-world mpg estimates at 23 mpg in 2020, up from 22.8 mpg in 2015. Stellantis was at the very bottom of the list, with average fuel economy decreasing from 21.8 mpg to 21.3 mpg.

At the top of the list for internal combustion manufacturers was Honda, which raised its average fuel economy from 28.5 mpg to 29.1 mpg during the five-year interval. Subaru was second, going from 28.1 mpg to 28.5 mpg, while Hyundai was third, going from 27.5 mpg to 28.4 mpg.

The industry average increased from 24.6 mpg to 25.4 mpg. The report also listed the MPGe (miles per gallon equivalent) for electric-vehicle maker Tesla, which rose from 97.1 MPGe to 119.1 MPGe between 2015 and 2020.

What’s more, the report looked at CO2 emissions, indicating that GM decreased its average emissions from 399 grams per mile to 386 grams per mile. The industry average emissions decreased from 360 grams per mile to 349 grams per mile.

The EPA’s estimated figures are based on laboratory tests that aim to simulate a wide range of operating conditions, including both hot and cold weather, higher speeds, and fast acceleration, as may be encountered by the average driver.

  1. And pretty soon they will be the worst with MPGe with the likes of the Hummer and Silverado EV.

  2. Not much of a surprise here since GM, Ford, and Stellantis biggest sellers are large trucks.

    1. Yeah fake statistics. The right way is to show what percent they were over/under CAFE requirements, which already take into account size of the vehicle.

  3. Toyota really is the worst for fuel economy, with the new tundra failing to exceed the decade old 5.3 in fuel economy. The EPA needs to be abolished. GM has the most efficient trucks, SUV’s and commercial vehicles. They have some very efficient cars that are in the top of the fuel economy pack as well, it’s just that they don’t sellany small vehicles. Should we start adding Volvo trucks to volvos fuel economy fleet?

    3. Volvo trucks and Volvo cars are actually two different companies. Just like Rolls Royce cars are not affiliated with Rolls Royce Jet Engines.

  4. Way to go Stellantis!!!! You sell those hellcat motors!!!!

    1. Save the Hellcats, end the CAFE scam

  5. This is not surprising since GM have given up on all but one of their fuel efficient sedans. I totally understand that more and more people are purchasing trucks and SUVs, but it surprises me that Toyota, Subaru, KIA, Hyundai and Nissan, just to name a few, are still pumping out cars and sticking with it. Just look at their sedan line up compared to GM and Fords.

    I think GM have done a great disservice to themselves and to their customers by not offering more sedans than just the Malibu. I also wished that GM would have continued to produce the Volt or the Voltec program. That would have been a vehicle that would have improved the company’s CAFE figures but also allow customers to feel more comfortable in owning an EV and use it as their primary vehicle for both long and short trips.

    1. Bingo. GM had a 50+ mpg Sedan but the monkeys that run the company never bothered to market the car ever then cancelled it due to poor sales.
      Their behavior over the Cruze Diesel forever will haunt GM whenever they preach about green & cares about the environment.

      1. poor sales because of consumer reports and anti-american network news (NBC ABC< CBS<MSNBC< serving up false scare tactics on a a daily basis..i e .. fire hazerd, and most anything the libs could come up with

  7. Well, what do you expect when 9 out of 10 vehicles you sell (not an official number) are V8 trucks and SUV’s? Of the 1 out of 10 left, 9 out of 10 of those are still V6 trucks and SUV’s. If you did a car by car (truck/suv/cuv) comparison with even the best MPG brand, the results would look much different. I can personally attest to the Mazda 2.5L not being very good for MPG’s. And talk about dogs.

    GM better get as many EV’s on the road as soon as they can along with a few more cars in the mix.

    1. GM’s big mistake is not including hybrids in the mix.

      Reply
      1. Yes Walt W. In fact, quite possibly the biggest mistake by GM (IMO) is that they didn’t keep the Volt and utilize the “Volt-tech” in many more vehicles. Huge mistake. I don’t care if their “plan” is to go fully EV in the near future. The Volt-tech would and should be a huge part of the electrification for them. Not everyone will get on board with a full EV and those people would be perfect candidates for the EV with the gas backup.

        Personally, I drive a Volvo S60 T8 at the moment. Although I really want to get back into a GM product, I have to say that I absolutely love the 87 MPG that I am getting and the fact that I can mostly run all electric but could drive the car across the country without charging once if I need. Volvo is also going in hard with all EV, but the PHEV (T8 in Volvo’s case) is a big part of their electrification process. Come on GM. Are you listening????

  8. Speaking of EV’s. According to Automotive News the ship fire with 4,000 vehicles, (Porsche, VW, Bentley, Audi), was caused by EV lithium ion batteries catching on fire. Forget the EV’s.

  9. GM sells a lot of big trucks and they have no hybrids in North America. The push for EVs is meant to rectify it.

    1. When gasoline hits $5 a gallon, gm will be selling less V8s so problem solved. We’ve seen this several times over the decades. Hopefully we won’t have had lines and shortages, again. Remember odd/even days? Looks like the 1970s are back. Thanks ,Brandon.

      1. Agreed … for months I’ve written about the need for the Chevy Astro mid-sized vans to make a come back, just to be heavily foul mouthed on this forum. I am a child of the ’60s and vehicles like the Astro were a huge part of my life in the 1970’s an 1980’s. Owning a large Power Equipment shop the cargo version of the vans proved bullet proof. On the private side the LS & LT trim Astros proved to be the best family wagons ever, especially when equipped with the *Dutch Door option. And both vans averaged about 21 mpg in town and from 25 to 26 mpg on the interstate. And what’d GM do … discontinue a proven vehicle with a huge fan base … then not even bring about a replacement. GM … Astro owners aren’t SUV owners, and only buy a SUV because there’s nothing else out there …. except for a Mercedes, I’m about to pull the trigger and buy Mercedes Metris … and cost … a ’22 model is only going to be about $9K more than the last new ’05 Astro LT trim van costed then.

      2. no.. you should thank that idiot moron biden

  10. That’s reasonable since GM most desirable vehicles are full-size trucks and SUV’s mostly powered by V8 engines, the same goes for Stellantis, but they add some muscle cars to the mix too.

    1. Then around 2014 they killed the great almost trouble free Colorados for the current version that one leading publication has almost graded it to avoid. In 2005 they did the same thing to the Astro, another bullet proof vehicle. Both the Astro/Colorado would give you around 21 mpg in town, and 24 to 25 mpg on the interstate. As I write this the news is reporting that the Ukraine is being bombed. All those soccer moms who drive those 15 mpg on a good day SUVs would really like to own a Astro in about two weeks “cause gas is gonna go up”.

      1. Our ’14 Impala with a V-6 gets 30-32 mpg on the road at 70 mph. It just turned over 100,000 miles. I would really like to get a new one – too bad I can’t.

      2. i;m guessing that “leading punlication” is consumer reports? the commie radical anti-american clinmate change radical s who claim they buy everything they test and rate? how can a publication buy 10’s of millions of $$ worth of merch when they have only a few thousand subscribers who are mostly in their late 70’s? wake up America

      3. you can thank “hair plugs” biden, the moron, for gas prices and not GM

        Reply
        1. Not hair plugs … but “ly’inbiden” … and had “ly’inbiden” not cancelled the Keystone Project the North East and Mid East parts of the US would have been seeing oil from that right now, and by the end of this year hopefully finished and producing for the entire country’s needs. But forget that, and don’t forget what you’re paying for LP an Natural Gas for home heating, etc … up almost 50% in NC.

  11. If you’re buying a Suburban or Tahoe or any full-size SUV and worried about gas mileage then you outta be walking or at home watching the news all day. I’ve owned over 20 GM SUVs from 2020 back to 1948 all had V-8’s in them and I never gave a crap about MPG. It was more like SPG…Smiles Per Gallon.

    1. That’s fine and dandy until your wallet bleeds in agony from your buying decisions.

  12. All I know is that my first car, a used 1971 VW Super Beetle, with a 1.6L, flat 4, 60 HP engine, got 20-25 MPG on leaded gasoline. The car weighed 1,780 lbs. Top speed was 82 MPH if you were lucky. 0-60 MPH was 16.4 seconds; it and the Chevrolet Vega were the slowest of all cars made that year. It didn’t have air conditioning and had trouble maintaining speed going up a steep hill.

    A 2022 Chevrolet Corvette Stingray with a 6.2L, V8, 490 HP engine, on unleaded gasoline gets 25 MPG! The car weighs 3,535 lbs. Top speed is 194 MPH if you are foolish enough to try it. 0-60 MPH is 2.9 seconds, one of the fastest of all cars made this year. It has AC and no trouble maintaining speed anywhere.

    The improvement in automobile technology to deliver that performance has been incredible.

    1. Now compare the price.

    2. Wow. How did you get 60 hp out of the VW??

      1. The “Super Beetle” engine was a little larger than the standard bug.

  13. gm is the company that killed the EV1 car. They did not and do not have a clue what people want outside of trucks and a few SUVs.
    They have no clue how competitive the BEV business is going to be. Quality and reliability are going to be in the front row.
