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.

GM delaying additional Silverado EV and Sierra EV production to Q4 2025

This looks like more "Gotcha!" news about storms in the EV sector, but the word "additional" is key here. The Detroit News reported today that GM is pushing delaying production of the Chevrolet Silverado EV and GMC Sierra EV pickups at the Orion Assembly Plant to late 2025, about a year behind expectations. The Silverado EV Work Truck is already in production at GM's Factory Zero in Detroit, which won't change. Retail versions of the Silverado EV are still planned for production at Factory Zero before the end of this year, and the Sierra EV is expected to enter production at Factory Zero early next year. This new plan simply means GM won't add more production of those electric trucks at Orion.  GM builds the Chevrolet Bolt at Orion right now, assembly of that groundbreaking car to end this year. GM's original idea was to spend $4 billion to convert Orion to EV pickup production in time to get its two giant profit makers rolling down lines in early 2025. The move to late 2025 could mean the plant is out of commission for about two years. The facility's 1,261 employees are being offered spots in other plants, including Factory Zero.  The automaker gave several reasons for the move, a spokesperson telling The Detroit News the company wants "to better manage capital investment while aligning with evolving EV demand," and telling the Detroit Free Press, "We're looking at EV demand and the trendline for EVs is stabilizing. ... It is not rising as fast as originally forecasted." On top of that, engineers "have identified engineering improvements that we will implement to increase the profitability of our products." The spokesperson also made it clear that the delay has nothing to do with the UAW strike, now in its 32nd day.  Factory Zero's working up to a near-term production capacity of about 600,000 units annually, GM saying it wanted to get capacity to 1 million EVs annually by the end of 2025. At the moment, the site builds the Silverado EV Work Truck, the GMC Hummer EV pickup and SUV, and the Cruise Origin shuttles — not the Bolt taxis, the autonomous pods. The Detroit News reported GM sold 18 Silverado EV Work Trucks in Q3 this year, GM Authority says GMC Hummer EV production has ramped up to about 3,000 units per month, and Cruise Origin is still waiting on approval from the National Highway Safety Traffic Administration to mass-produce the autonomous shuttles because the shuttles need an exemption for not having steering wheels.

GM says its electric pickup truck is 'in development'

GM President Mark Reuss just reiterated the company's support for an electric pickup project. He also claimed that GM is going to be selling its future electric cars at "very average transaction prices" during the same conference with Wall Street analysts. Previously, Mary Barra informed the world of GM's electric pickup truck aspirations, but didn't tell us anything else. Reuss says the truck is already in development, though, according to a Wards Auto report. "We will have a complete electric lineup, including a pickup truck that's in development," Reuss said. This comment marks the second time GM has gone on the record about its intentions to bring an electric pickup to market. Additionally, Reuss said GM's third-generation global EV platform will be used to help develop the electric pickup. This platform was recently announced to underpin at least 20 new EVs from GM in the future — the platform itself is slated to be unveiled in 2021. Of course, this platform will be flexible and modular to allow various body styles to be used with it, a truck being one of those. Reuss still hasn't said what GM brand the pickup will be sold under, or what class of truck it will be. GM thinks this new platform is also going to be what helps it drive down the cost of building EVs. "We'll reach parity a lot sooner than people think," Reuss said comparing EVs to traditional gas-powered engines. "We're driving down the cost of batteries and the whole EV in general." As for electric pickups, Ford is also deep in development of its own electric F-150. However, neither of these truck projects have official timelines on them, so we can't say when they'll hit the market. For now, the cross-town rivals are both in development with their respective electric pickups. Even further across town is Rivian (in which Ford just invested half a billion dollars), a company that says its electric R1T pickup is right around the corner, with the official due date being end of 2020 for the time being.
