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.

1972 Dodge Challenger on an M1009 CUCV military frame is YES

The subject of this post is cause for celebration, not reason to ask "But why?" We don't know why this random Craigslist seller chose to marry the body of a 1972 Dodge Challenger with the frame and axles from a 1987 Chevrolet M1009 military vehicle. We're here to appreciate it, thanks to The Drive, and maybe spend some time after dinner considering whether to buy it. Now that we're on the same page, an owner in Tucson wants to rid his garage — or his Bullet Farm — of what appears to be an exceptionally well built conversion. Starting from the bottom, the M1009 CUCV, for Commercial Utility Cargo Vehicle or "Cuckvee," emerged from a program turning K5 Blazers into supply rigs that were meant to support hardcore hardware like the AM General Humvee. The M1009 got GM's 6.2-liter Detroit Diesel V8, a TH400 transmission, an NP-208 chain-driven transfer case, a 10-bolt rear axle and 3.08 gears. Produced from 1983 to 1987, they returned "less than desirable" results in the field and the military unloaded them. Not much of that remains for this build. The diesel got dropped, replaced by a 5.7-liter GM gasser with a four-barrel carb and long-tube headers, shifting though a 4L80E automatic transmission attached to a U.S. Shift Quick 1 transmission controller in the cabin. The seller doesn't mention output, but if it's a more recent Chevy 350 then it'll certainly provide a healthy bump over the maximum 160 horsepower from the diesel, especially running through a custom Flowmaster dual exhaust. An NP-205 two-speed transfer case switches between 2H, 4L, and 4H. The Dana 44 front and Dana 60 rear axles feature lockers and 3.52 gearing in back. Skyjacker Black Max provides the suspension to keep the 37-inch BFG KM2 on the pavement or the dirt. About 11,000 miles ago the owner rebuilt and upgraded the drivetrain, installing new accessories like a high-rise intake, four-core radiator, new alternator and Holley fuel pump. Losing the K5 body for an E-body Challenger cap means losing M1009 features like the rifle rack and gas can mounts. But you gain style, something real hard to find on a vehicle stout enough to back you up when you tell the crew, "I've been to hell and I'm going back." As part of that rebuild a few miles back, the minimalist interior got all new panels, dash and custom gauges, headliner, seats, and a Sony audio system with Alpine amps, a sub, and Kenwood speakers.

2017 Chevrolet Trax brings its fresher face to Chicago

The 2017 Chevrolet Trax's facelift does wonders for the compact crossover's looks. There's nothing overly offensive about the model's current design, but it's rather drab, especially at the front. As you can see from these live photos from the Chicago Auto Show, the revised Trax simply looks more modern than the current model. It now wears narrower wraparound headlights that integrate nicely with the upper level of the grille. The lower portion of the front end gets a more angular shape, and there are big crevices for the foglights. The rear also has small revisions, including new taillights and tiny changes to the bumper. With this refresh, Chevy has brought its little CUV's looks closer in style to the brand's stalwart sedans, the Cruze, Malibu and Impala. Inside, the Trax now features analog instruments for the speedometer and tachometer, but there's still a big screen on the right side to display vehicle information. The CUV also gets Chevy's seven-inch MyLink infotainment system that buyers can option with Apple CarPlay, Android Auto, and 4G LTE support. Active safety tech like side blind zone alert, rear cross traffic alert, forward collision alert, and lane departure warning are available on the 2017 model, too. While the 2017 Trax looks a lot better, it's the same vehicle mechanically. It won't arrive at dealers until this fall, but you can check one out now in our gallery above.
