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.

A Chevy Camaro hybrid? That's what EcoCAR3 could bring

Figuring out a way for a hybrid powertrain to co-exist with the performance expectations of a classic American muscle car is a challenge that could vex that most experienced of automotive engineers. It's a challenge, in fact, being handed to a bunch of college students. Over the next four years, students from 16 North American colleges and universities will attempt to wring fuel efficiency from a 2016 Chevy Camaro as part of EcoCAR3, an advanced-vehicle technology competition sponsored by the Department of Energy, General Motors and others. They'll be attempting to use hybrid or plug-in hybrid technology while not sacrificing the performance of the Camaro, which was selected in part because the current model achieves just 17 miles per gallon in city driving and 28 MPGs on the highway, per EPA numbers. Students will get the latest version of the vehicle to work on, one that is expected to be unveiled next month on Belle Isle in Detroit. "If we still want to produce V8 Camaros, we're going to have to look at alternative methods of propulsion," said Al Oppenheiser, the chief engineer on the Camaro. "So the ideas that these college teams come up with could very easily be adapted to a car like the Camaro." Unlike similar competitions that reward fuel efficiency in vehicles, EcoCAR seeks those gains while emphasizing cost and consumer acceptance of these vehicles. The cars shouldn't look like experiments; they should look like everyday vehicles on the road. Previous competitions have allowed the teams to use whatever powertrain they desired. This time, EcoCAR officials designed the competition to concentrate on hybrid, hybrid-electric and diesel options. Competitors won't have the option of using hydrogen fuel cells as they have in the past. Last year, a team from Colorado State built a vehicle that contained both hydrogen and electric power sources. This year's limit is a curious choice, as some automakers such as Toyota have placed heavy bets on fuel cells in recent years. General Motors also runs a fuel-cell program. With the focus on cost and practicality, however, the program officials wanted to narrow the framework of the contest. "We always have some good decisions on what to make within the scope or out of scope," said Jim Kolhoff, global director of software engineering for General Motors.

Danica Patrick hands over keys to first 2016 Chevy Camaro

Alican "Turk" Boyacioglu got more than he expected this weekend when he picked up his new 2016 Chevy Camaro, the very first sixth-gen Camaro to be delivered to a private customer. That's because racer Danica Patrick was on hand for the delivery. The handing over of the keys took place at Texas Motor Speedway – a stop along the brand's Find New Roads trip. The journey is being conducted to introduce America to five new Chevy models: the Camaro and also the new Malibu, Cruze, Volt, and Spark. The road trip kicked off on October 19 and will conclude next week on November 14. Boyacioglu ordered up a red Camaro SS from Huffines Chevrolet in Lewisville, TX, north of Dallas. When he headed from Kansas to northern Texas to take delivery, he was pleasantly surprised to see Danica climb out of the car to hand him the keys. Though she may have raced under Honda power during her IndyCar days, Danica's NASCAR stock cars have always been powered by Chevrolet. She even drove a Camaro in the Nationwide Series. The smile on Turk's face ought to last him the nearly five-hour drive home to Wichita. For everyone else, deliveries are set to commence in earnest in the middle of this month. The first models to be delivered will be V6 coupes. Convertibles and turbo-four models will start shipping early in the new year. Customers will be able to choose between six powertrain combinations, made up of the 2.0-liter turbo four, the 3.6-liter V6, and the 6.2-liter V8, each available with a six-speed manual or eight-speed automatic. Pricing starts at $26,695 for the base 1LT trim and extends up to $37,295 for the 1SS. DANICA PATRICK SURPRISES CUSTOMER WITH 2016 CAMARO Huffines Chevrolet delivers first 2016 Camaro to Alican 'Turk' Boyacioglu DALLAS – Racecar driver Danica Patrick helped the team at Huffines Chevrolet deliver the first sixth-generation Camaro to a customer from Wichita, Kan., at the Texas Motor Speedway stop of Chevrolet's Find New Roads Trip today. Alican "Turk" Boyacioglu had been eagerly tracking the build of his 2016 Camaro SS and could not contain his excitement when Patrick emerged from the car and handed him the keys. "This whole experience was surreal," Boyacioglu said.
