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.

The U-2 spy plane needs high-performance cars to help land

Typically, aircraft deploy their landing gear from three main points. Most military aircraft, for example, deploy two gears at the back and one forward, like a tricycle. Some civilian aircraft flip the layout, with two in front and one in back - tail-draggers. The U-2 Dragon Lady is wildly different than any of these. With a 103-foot wingspan but a body that's just 63-feet long, the layout of the U-2 makes a traditional landing setup infeasible. Instead, the U-2 utilizes a pair of wheels, one up front and one in back. With such a bizarre layout, landings are so tough that since the U-2's earliest flights at Area 51, the US Air Force has used high-performance chase cars to guide the pilot down safely. The landing process isn't over there, though. As this video from Sploid shows, balancing out the aircraft to fit the detachable "pogos" – think training wheels for spy planes – is a comical procedure requiring a number of airman using their full body weight to even out the U-2. This video also recaps some of the great vehicles that have served as chase vehicles for this legendary spy plane. They include Chevrolet El Caminos, and the Fox-body Ford Mustangs so favored by the California Highway Patrol. For the last several years, the USAF has utilized products from General Motors, using fourth-generation Chevy Camaros, before switching over to the Pontiac GTO and most recently, the awesome Pontiac G8. It's fair to say that if you're a gearhead in the Air Force, this is the job you want. Check out the video, embedded up top.

Drivers buy new $300K McLaren 720S, 2019 Chevy Corvette, and wreck 'em

Two high-powered, high-priced sports cars, wrecked in their infancies. No doubt they were fun while they lasted. In Great Falls, Va., a tony suburb of Washington, D.C., that hugs the Potomac River, someone was out enjoying driving the McLaren 720S they had purchased only the day before on a leafy, two-lane road. Then, horror: In an instant, the car hit a tree, mangled and destroyed "because of speed," according to the Fairfax County Police Department. Purchased Friday. Totaled Saturday. This McLaren 720S, costing around $300,000, was destroyed today in Great Falls because of speed. The driver was taken to the hospital with thankfully only non-life threatening injuries. A reminder to slow down, or it could cost you. pic.twitter.com/XhC3LKRY1t — Fairfax County Police (@FairfaxCountyPD) July 14, 2018 Then on salvage auction site Copart, a brand-new orange 2019 Chevrolet Corvette Grand Sport lies in a warehouse in Lincoln, Neb., its front left corner crushed, wheel askew. It had just 15 miles on the odometer. We know nothing of the backstory, except for the obvious front-end damage and secondary damage to the undercarriage. The rear end and 6.2-liter V8 engine, which makes 460 horsepower and 465 pound-feet of torque, look OK. The most current bid as this was published was just north of $9,000. It's tempting in both cases to assign the blame to over-eager drivers who weren't quite yet able to corral all that power. In the case of the McLaren, the supercar makes 710 horsepower and 568 pound-feet of torque from its quad-cam, twin-turbo 4.0-liter V8. It goes from 0-62 miles per hour in 2.9 seconds and boasts a top speed of 212 mph. We're not saying the unidentified driver was a newbie, but this car is definitely not for newbies. Police write that the incident is "A reminder to slow down, or it could cost you." As in, $300,000. Or at least the depreciation for driving it off the lot. Related Video:
