Next-gen Chevy Volt will get 1.5-liter, four-cylinder engine

As General Motors gets ready to unveil the new Chevy Volt at the Detroit Auto Show in January, it's starting to reveal a few more details about the updated plug-in hybrid. Today should be fruitful on that front, thanks to an event GM is hosting today that focuses on the new Volt, and we've just had the first bit of new: a bigger engine is coming. Since the beginning, the Volt has used a 1.4-liter, four-cylinder engine as a range extender when the battery runs dry. The second-generation model will instead get a slightly larger 1.5-liter, four-cylinder engine that will be built in Flint, MI. That's a step up from the various engines that have been a part of the 2016 Volt's rumored mills, everything from a 1.0-liter or 1.2-liter three-cylinder to a 2.0-liter turbo. The confirmation about the new 1.5-liter powerplant was found in Automotive News, where we also heard again that GM is going to start building the new Volt's electric drive unit in Detroit, moving production up from Mexico. We will have more information on the 2016 Chevy Volt later today.

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.

Volvo and GM team with Amazon for in-car deliveries

Volvo and GM are the first automakers to pair their vehicles with a new service from Amazon that lets owners have their packages delivered inside their cars, without them having to be there. The service will initially be rolled out in 37 U.S. cities at no extra charge to Amazon Prime members with a Volvo On Call or OnStar account, and it works with same-day, two-day and standard shipping. It's intended as an alternative for people who don't want to risk having their package stolen from their front porch or receive deliveries at their workplace, and both automakers say it's an example of how they're embracing innovation as a way to make their customers' lives easier. Volvo released a video (above) showing how the service works. Users download the Amazon Key App (or " Ama-zin," as the narrator pronounces it) and link their Amazon Prime account with their Volvo On Call account — or OnStar, in the case of GM-branded vehicles. Once they register their delivery location in a publicly accessible location, users can select the "In-Car" option at checkout. They get a notification when the delivery is en route and once it's completed and the car is relocked. Volvo has been offering in-car delivery in certain European countries since 2015 through its Volvo On Call platform, which enables services like the ability to send calendar-based navigation destinations directly to the vehicle, find nearby gas stations and help locate the vehicle when you forget where you parked it. Volvo says the platform is now available in roughly 50 countries and covers more than 90 percent of its global sales. The service is compatible with 2015 or newer Volvo, Buick, Cadillac, Chevrolet and GMC vehicles. Volvo says it's available to the majority of Volvo owners, while GM says more than 7 million vehicle owners can qualify. The service is expected to roll out to more cities later.
