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.

Toyota Supra, Rolls-Royces, dozens of BMWs recalled for backup camera issue

Weeks after Nissan and Infiniti recalled more than 1.2 million vehicles for a potentially dangerous programming oversight in the backup camera settings, BMW has issued a recall for similar problems. The recall, which covers 257,481 vehicles, includes numerous BMWs, as well as two Rolls-Royce models, and the 2020 Toyota Supra.  In total, the recall potentially affects 51 different products. This includes the 2018 BMW 540D, 2018–2019 BMW 640I, Rolls-Royce Phantom, 2018–2020 BMW 530e, 530i, 540i, M5, M550i, X3, 2019 Rolls-Royce Cullinan, 2019–2020 BMW 330I, 740Le, 740Li, 745Le, 750Li, 840i, M340i, M850i, X4, X5, X6, X7, Z4, and 2020 Toyota Supra. On certain BMW models, xDrive variants are also included. According to NHTSA campaign No. 19V684000, "The back-up camera and display settings can be adjusted such that the rearview image is no longer visible and the system will retain that setting the next time the vehicle is placed in reverse." If there is no display image when backing up, drivers can't properly see, and the car no longer meets modern safety regulations. Specifically, Federal Motor Vehicle Safety Standard (FMVSS) number 111, "Rearview Mirrors."  The recall was filed on September 27, 2019, and BMW plans to begin notifying affected owners in November. BMW, Toyota, and Rolls-Royce dealers will update the vehicles' software, which should fix the problem. 

Toyota, Ford decide to end hybrid collaboration before it starts

Not all so-called Memorandum of Understanding pacts end in actual collaborations. For instance, after a two-year "feasibility study," Toyota and Ford have just announced that they will not be developing hybrid systems for use in light trucks and SUVs as previously planned, and the two automakers will instead continue to develop their own hybrid technology independently.
The would-be collaboration was first announced in August of 2011, and would have seen a rear-wheel-drive hybrid platform that would "improve the efficiency of trucks and SUVs while still allowing them to be driven in the way customers expect," according to our initial post on the topic.
Keep in mind that this announcement isn't to say we shouldn't expect hybrid pickups and SUVs from the two automakers, but that they probably aren't coming very soon - Ford says it will have a system "before the end of this decade" and we haven't heard much from Toyota on the hybrid truck front since the 2008 A-BAT Concept (pictured above) - and that they will not share any components between them (and they never have, for what it's worth).
