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 blends Jeep and McLaren F1 in playful concept

Auto shows aren't the only place where Toyota showcases its concepts. It also cooks up something new every year for the Tokyo Toy Show. This year it's the Camatte Hajime, and it's the sixth iteration in a line of youthful concepts following the Camatte Sora, Daichi, 57s, and 57s Sports we've seen in recent years. It blends the best elements from a Jeep Wrangler and a McLaren F1. Okay, so it's more like a Jeep, but it does have the McLaren's signature central driving position and two passenger seats offset just behind. It's also a fair bit smaller than anything Jeep makes, and packs an electric motor of unspecified capacity. Fortunately it'll be switched off while on display at the Tokyo Big Sight during the toy show, so kids can get in and stomp on the pedals all they want. (Stomp in a polite and respectable Japanese fashion, anyway.) Families can have their picture taken inside the open cockpit, then customize the vehicle on tablets to create their own unique memento, while checking out other versions including an ambulance, police car, fire truck and hod dog truck. Childhood Vehicle Playsets Meet the Information Age at the Tokyo Toy Show Tokyo, Japan, June 17, 2015-Ever wonder how you would look racing to rescue a cat from a tree in a purple fire truck? Or cruising around town in a hot pink hot-dog truck? Now you can see for yourself through Camatte Vision, an all-new interactive experience from Toyota for families, debuting at this year's International Tokyo Toy Show. Camatte Vision is the latest way to experience Toyota's Camatte line of exploratory concepts seeking to break the traditional boundaries of the way children play and tinker with vehicles. The aim is to let kids and their parents share the child-like wonder and excitement of cars and trucks. Blazing fast hot rods, life-saving ambulances, hearty construction crane trucks, and many more are available in a rainbow of colors. Through an innovative augmented reality tablet app, see how you and your family would look in a virtually limitless combination of vehicle types and colors. Of course, the fun doesn't end in the virtual world: the latest physical manifestation of the Camatte family, the Hajime, will be on display for families to explore hands-on.

Economy-car buyers increasingly get the best deal on technology

One of the great things about technology is – with the exception of Apple products – consumers get more for their money every year. For example, the first 1GB USB drive I bought in 2005 cost me $30. Today you can get 10 for that price, delivered to your door thanks to Amazon. The same goes for car tech. Features such as navigation and Bluetooth started out on high-end vehicles before trickling down to entry-level cars. Same with driver assist features ranging from rearview cameras to forward collision warning with automatic emergency braking — so now it's not only rich people who are protected in car crashes. I've found that this democratization of tech has reached a point where amenities on low-cost cars can be as good — and sometimes even better — than those on vehicles costing tens of thousands of dollars more. While attending a media event for the launch of the all-new 2019 Toyota Corolla Hatchback, I was impressed by the car's cool styling and go-kart performance. Equally noteworthy is the amount of standard tech on the low-cost hot hatch. (Pricing will be announced later this month, but expect it to come in a bit higher that the current Corolla iM's roughly $19,000 base.) Even the base SE CVT trim of the 2019 Corolla Hatchback comes with an 8-inch touchscreen and Toyota's Entune 3.0 infotainment system. Among other features, Entune 3.0 provides Wi-Fi capability, Amazon Alexa connectivity, the Entune App Suite for integration of smartphone apps such as Pandora and Yelp and, for the first time in a Toyota, Apple CarPlay (but no Android Auto). The 2019 Corolla Hatchback is also the first North American vehicle to get the second-generation Toyota Safety Sense (TSS) suite of driver assists that's also standard on the base model. TSS 2.0 includes Toyota's Pre-Collision System (forward collision warning with automatic emergency braking) with new daytime and low-light pedestrian detection and daytime cyclist detection features, lane keeping and lane departure alert with steering assist, auto high beams, adaptive cruise control, and road sign detection. While the 2019 Corolla Hatchback sets a new benchmark in standard tech on a budget-mobile, competing cars aren't far behind. The 2018 Honda Fit LX, for example, includes forward collision warning with automatic emergency braking, lane departure warning and assist and adaptive cruise, while the automaker's Lane Departure Mitigation and Lane Watch camera system is added the two top trims.
