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.

2018 Technology of the Year Award | We chat with Lexus about the LC 500h's hybrid system

Every year, Autoblog editors test dozens and dozens of the newest vehicles available, sometimes even before they're available. From those vehicles, we select the ones we think provide the most innovative technology in the industry. Then we pare the list down to the very best, test them again, and vote on our winner for Technology of the Year. This year, Lexus's multi-stage hybrid system — as tested in the LC 500h — came out ahead of the rest of the finalists. We chose the 2018 Detroit Auto Show to hand over the award to Lexus Group Vice President and General Manager Jeff Bracken. He was kind enough to sit down with Autoblog Senior Editor Alex Kierstein and Green Editor John Snyder at the Lexus stand to talk about the hybrid system, what it does, and what it means for the future of Lexus and Toyota. Check out the video above, and follow along for all our coverage from the 2018 North American International Auto Show in Detroit, where we are taking a look at all of the new cars and technology that we'll see in the near future. Perhaps the next winner of Autoblog's Technology of the Year award is sitting somewhere on the Detroit show floor.

Incrementally better than ever | 2017 Toyota 86 First Drive

We'd love to tell you that the incremental upgrades bestowed upon Toyota's rear-wheel-drive coupe as it made its transition from Scion FR-S to Toyota 86 have transformed it into a perfect sportscar. If only a few more horsepower, shorter rear-end gearing, and tiny aero updates were enough to quell all the complaints that enthusiasts have leveled at the machine since the platform first hit the road in 2012, this review would have been so much more satisfying to write. Sadly, that's not the case. Don't get us wrong. The 86 is still extremely fun to toss around a twisty road. The chassis is impressively balanced, the steering is direct, and the shifter is sweet. Sorry to impart upon you this well-worn trope, but the old adage that it's more fun to drive a slow car fast than it is to drive a fast car slow is, in this case, completely accurate. The 2017 Toyota 86 is nothing if not entertaining. But it's not completely new. It hasn't been transformed. It is, in the end, the same as it ever was. It will take about three minutes of your time to watch the videos below, in which we cover pretty much everything that's new for the 2017 Toyota 86. Toyota 86s equipped with manual transmissions get a five-pony boost to 205 horsepower and 156 pound-feet of torque. Automatic models soldier forth with a carryover 2.0-liter four-cylinder that puts out 200 hp and 151 lb-ft. Apparently, more than half of Scion FR-S buyers chose the automatic. That's unfortunate, as it drains a good deal of the fun out of the 86 experience. Choose the manual and you'll be rewarded with an easy clutch and a rewarding short-throw shifter. And, as we said, five more ponies, courtesy of intake and exhaust tweaks and the polishing of some internal engine components. The only upside to the automatic is improved fuel economy of 24 miles per gallon in the city and 32 on the highway. Manual 86s are EPA-rated at 21/28. Along with the small bump in power, the 2017 86 gets a 4.3:1 rear-end gear ratio in lieu of the old 4.1:1 unit. That ought to translate into a small improvement in acceleration that really only matters on paper. In the real world, on actual roads, the difference is negligible. To eke the most out of the 86, you have to constantly work the shifter and keep the engine north of 5,000 rpm. It's still not particularly quick, but it's definitely fun. There's plenty of noise inside the 86, from the wind, the road, and the engine.
