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 recalling over 40,000 Chevy, Pontiac and Saturn models over fuel pump woes

The National Highway Traffic Safety Administration has issued a recall for a number of General Motors cars and crossovers bought or currently registered in the hot-climate states of Arkansas, Arizona, California, Nevada, Oklahoma and Texas. As many as 40,859 units consisting of the 2007 Chevrolet Equinox, Pontiac Torrent and Saturn Ion and the 2007-2009 Chevrolet Cobalt (shown) and its Pontiac G5 twin are being recalled for potential fuel leaks.
This recall is being issued due to potentially faulty fuel pump components that can crack and cause gasoline to leak from the return or supply ports and possibly cause a fire. NHTSA has not indicated how many fuel leaks or vehicle fires have been reported. As a fix, GM will replace the fuel pump modules on all affected vehicles free of charge. Since Pontiac and Saturn have been shuttered, owners will be able to go to another GM-brand dealership to have their vehicles repaired.
While the list of affected cars and crossovers varies by state and model year, if you own any of these models and live in Arizona, California, Florida, Nevada, Oklahoma or Texas, be sure to check the official notice below for more details.

2022 Chevy Suburban, Tahoe, GMC Yukon, Cadillac Escalade up another $1,600

The 2022 Chevrolet Tahoe and Suburban, the 2022 GMC Yukon and the 2022 Cadillac Escalade have all gone up by $1,600. The GM profit and loss department added $1,500 to the MSRP for each of the full-sized SUVs and $100 to their destination charges, that destination fee now $1,795 for each vehicle. It's not an inconsequential bump; however, considering where the trucks were priced at launch, and everything that's happened since, the latest retail prices don't seem that bad. Take the Suburban — in February 2020, Chevrolet practically carried over pricing for the truck with a revamped interior and independent rear suspension, starting it at $50,295 after destination. After this latest increase, the 2022 Tahoe LS in two-wheel drive costs $55,590, after destination.  The delta between the 2021 Suburban at launch in March 2020 and the current model is a little grander compared to the Tahoe, like the SUV itself. Back then, it started at $52,295, the same price as the outgoing model. After this third price increase in the past year, the 2022 Suburban LS in 2WD starts at $61,290 after destination. GM Authority says the 2023 Tahoe and Suburban are reportedly headed down production lines in the middle of July. The biggest addition to both models will be the availability of Super Cruise, which is already available on the sister SUV, the Cadillac Escalade. The hands-free driving assistance feature can only be optioned on the Premier and High Country trims. It costs $2,500 to put Super Cruise on the Escalade. GM hasn't divulged the feature's price yet for the Chevy twins; that's likely to come when the automaker announces 2023 Tahoe and Suburban MSRPs, so beware of more potential price increases. After that, there's a heavy refresh planned for the 2024 model year, including a new instrument panel design that looks like it replaces the current gauge cluster with a large, freestanding screen.  The Yukon's entry-level price goes up to $57,590 for the SLE trim turning the rear axle.   The Cadillac Escalade's second MSRP bump takes it to $81,235 for the Luxury 600 trim in 2WD, and $84,235 for the extended ESV model in the same trim. The price creep hasn't stopped Escalades from pulling off dealer lots almost as soon as they're delivered, sales for the first quarter of the year totaling 10,505 units, trouncing domestic and foreign competition.
