GM puts 3 million miles on hydrogen fuel cell test fleet

Have General Motors' hydrogen fuel-cell vehicles emitted enough water vapor over the past six-plus years to equal the steam coming out of Old Faithful? Not exactly, but GM has released a few figures related to the Project Driveway initiative it began in 2007. The numbers are impressive, if not quite of the geyser-spouting variety. In all, the General converted 119 Chevrolet Equinox SUVs to run on hydrogen, and those vehicles have just collectively surpassed the 3 million mile mark. And if you were waiting for us to tell you that the distance equals a half-dozen round trips between the earth and the moon, well, there you go. The better news is that the SUVs have combined to save almost 158,000 gallons worth of gas, and some of the vehicles have more than 120,000 miles on them. More than 5,000 drivers have participated in the project. GM reached that landmark about 10 months after it announced that it was working with Honda to accelerate the development of hydrogen fuel-cell powertrain technology. The two companies estimated last summer that it may have something to sell to the public as soon as 2020. For now, you can check out General Motors' press release below. GM Fuel Cell Fleet Tops 3 Million Miles Chevrolet Equinox fuel cell vehicles driven in real world reach milestone DETROIT – General Motors' fleet of fuel cell vehicles recently passed 3 million miles of hydrogen-powered, real-world driving. Some individual vehicles have accumulated more than 120,000 miles. By GM's estimate, using hydrogen to power these vehicles, the fleet has avoided 157,894 gallons of gasoline consumption. This specially equipped fleet of Chevrolet Equinox Fuel Cell vehicles are part of GM's 119-vehicle Project Driveway program, which launched in 2007. Since then, more than 5,000 drivers have provided feedback on the functionality and drivability of fuel cell technology. "Hydrogen fuel cell technology is an important part of GM's advanced propulsion portfolio and we continue to make substantial progress in furthering this technology," said Charlie Freese, executive director of GM's global fuel cell engineering activities. "These vehicles have operated through seven full winters and a wide range of environmental conditions, proving that fuel cells can meet the demands of real-world drivers." Last year, GM announced two fuel cell-related collaborations.

This map reveals the cleanest vehicles based on location

Naysayers love to point out how dirty the electricity grid mix is when it comes to charging electric vehicles. Curmudgeons are eager to jump into any conversation about EVs to enlighten the lucky listeners about how plug-in cars contribute to pollution, sometimes even throwing in a dash of climate-change denial for good measure. (Thanks, buddy. Pray, tell me more about the plight of oppressed SUV owners.) Unless someone buys an EV just because they think they're cool (which, yeah, they often are), they probably have at least a passable understanding of their environmental pros and cons. As many EV owners are already aware, location has a lot to do with any particular plug-in car's carbon footprint. Still, there's always more to know, and knowledge is not a bad thing, especially if one uses it to do the right thing. That's why this handy-dandy map from Carnegie Mellon University is so interesting. CMU researchers have compiled information about the lifecycle greenhouse gas emissions of various EVs based on where they're charged, as compared to gasoline-powered vehicles. The researchers looked at the Nissan Leaf, Chevrolet Volt, and Prius Plug-In Hybrid versus the gasoline-dependent Toyota Prius hybrid and the stop-start-equipped Mazda3 with i-ELOOP and compared grams of CO2 emitted per mile. CMU takes into account the grid mix, ambient temperature, and driving patterns. CMU takes into account the grid mix based on county, as well as ambient temperature and driving patterns in terms of miles traveled on the highway or in the city. For instance, if you drive a Nissan Leaf in urban areas of California, Texas, or Florida, your carbon footprint is lower than it would be if you were driving a standard Toyota Prius. However, if you charge your Leaf in the Midwest or the South, for the most part, you've got a larger carbon footprint than the Prius. If you live in the rural Midwest, you'd probably even be better off driving a Mazda3. Throughout the country, the Chevrolet Volt has a larger carbon footprint than the Toyota Prius, but a smaller one than the Mazda3 in a lot of urban counties in the US. The Prius and Prius Plug-In are relatively equal across the US. Having trouble keeping it straight? That's not surprising. The comparisons between plug-in and gasoline vehicles are much more nuanced than the loudest voices usually let on.

Cheapest SUVs of 2024

There is no doubt that cost is the number one decision maker when it comes to purchasing a vehicle. As prices continue to climb, affordable choices are getting harder to find, so we dug through what's available to find the least expensive SUVs in the most popular classes.  These prices are current as of January 2024, using available manufacturer suggested retail prices for 2024 models wherever possible. The prices include destination fees, but not dealer markups or incentives. Cheapest small SUV: 2024 Hyundai Venue Not surprisingly, the most affordable SUVs are the smallest. There's a whole host of subcompact SUVs out there, with some of the first introduced being the Nissan Juke, Mini Countryman and Kia Soul. In the beginning, these micro utes were marketed to empty nesters and first-time buyers, but nowadays they represent an alternative to the conventional sedan and have been increasing market share ever since. Profit margins in this class are narrow and popularity is high, which means the entrants are competitively priced. The top choices in the class are only a couple thousand dollars more than the most affordable alternatives below, so it may make sense to consider our favorites that include the Mazda CX-30, Volkswagen Taos and Chevrolet Trax. 2024 Hyundai Venue: $21,135 The Hyundai Venue debuted in 2020 and earned praise for its overall value. You get a ton of features for the money as well as a very generous warranty. Holding it back is its rather weak engine and very tiny proportions. Honorable mentions: 2024 Chevrolet Trax: $21,495 2024 Kia Soul: $21,565 Cheapest midsize SUV: 2024 Chevrolet Equinox Compact SUVs have the broadest appeal thanks to a very diverse group. It seems as though there's a great pick for nearly every taste, whether you're seeking something sporty, rugged or luxurious. They're a great pick for small families with one child and/or a dog. The class is led by vehicles that include the Honda CR-V, Kia Sportage and Mazda CX-50, which are still within reach of most shoppers' budgets. 2024 Chevrolet Equinox: $27,995 The Equinox debuted back in 2005 and this current third-generation was last redesigned in 2018, though a new one is right around the corner for the 2025 model year. While the current 2024 model may be showing its age, it still deserves your consideration for its comfortable ride quality, confident cornering and roomy passenger space.
