Weekly Recap: Toyota wants cars to be your 'close friends' around 2020

Toyota confirmed plans this week to launch autonomous technology in its production cars around 2020. The automaker's version is called Highway Teammate, and it's one element of a broader mobility strategy that includes vehicles communicating with each other and the grid. "Toyota believes that interactions between drivers and cars should mirror those between close friends who share a common purpose, sometimes watching over each other and sometimes helping each other out," the company said in a statement. That sounds utopian, and perhaps a bit cheesy, but it's an acknowledgment that autonomous driving requires more than technology developed in a vacuum. Toyota is looking at its research in a broader context, and dubs its overall strategy the Mobility Teammate Concept. Highway Teammate is the first step. Its test vehicle is a modified Lexus GS, which uses road-mapping data and external sensors to merge or exit highways, change lanes, and maintain safe distances during driving. It's operated on the Shuto Expressway in Tokyo. Toyota has been working on autonomous tech since the 1990s, with the goal of providing mobility for older people and the disabled, as well as lowering the frequency of traffic accidents. Toyota's push comes as an early adopter, Nissan, is hedging on its own deadline to implement the autonomous tech by 2020 due to a lack of firm laws governing self-driving cars around the world. Conversely, Volvo took the landmark step of being the first automaker to accept liability for when its cars will operate in autonomous mode, and urged the US government to set federal guidelines to regulate the technology. OTHER NEWS & NOTES 2016 BMW M4 GTS: Your water-injected, turbo-boosted demon BMW is unleashing its most powerful M4 ever, a 493-horsepower special edition that's road legal yet bred for the track. The company is making 700 copies for sale around the world, and 300 of them will come to the United States. The twin-turbocharged 3.0-liter six-cylinder revs to 7,600 rpm and uses a water-injection technology to cool the intake air and lower the compression temperature. BMW says this allows it to wring more power out of the inline six. The car also uses carbon-fiber reinforced plastic for the roof, hood, engine compartment strut brace, drive shaft, and rear spoiler to reduce weight. The M4 features BMW's organic light-emitting diode taillights, which are said to be an industry first.

Recharge Wrap-up: LA Auto Show may feature updated Cadillac ELR, Uber expands Chicago HQ

A Kentucky man has converted his 1939 Dodge pickup to an electric vehicle. Al Gajda of Lexington built the electric truck, which he now uses as his daily driver. "I take advantage of any excuse to drive it; just banging around town, errands, short runs on the interstate, delivering my granddaughter to school in the morning," he says. It is powered by a lithium-ion phosphate battery, which is mounted in a wooden box on the truck bed, and gets about 100 miles per charge. Read more at the Lexington Herald-Leader. Elon Musk will speak at the Automotive News World Congress in January. The Tesla CEO is a featured speaker for the program, "Setting the Pace in a Thriving Market." The event takes place in Detroit, which could lead to an interesting mix of people in the audience, and Musk will speak on January 13. Read more at Automotive News. Production of the Toyota Rav4 EV has ended. The shipment of the final Toyota EVs concludes Toyota's deal to source batteries from Tesla. Of the 2,600 Rav4 EVs to be produced, there are probably just a few hundred left to be sold, most of which are likely to be gone by the end of October. Read more at Inside EVs. Cadillac will likely show an improved version of the ELR at the Los Angeles Auto Show in November. The 2016 ELR will include unspecified "engineering enhancements," according to Cadillac spokesman David Caldwell. There will be no 2015 model, as the 2014 model will be sold until the 2016 ELR goes on sale in the first half 2015. Read more at Edmunds. Uber executives, along with Illinois Governor Pat Quinn, have announced a major expansion of the ride-hailing company's Chicago headquarters. Uber also plans to add 420 jobs by the end of 2016. "Uber's new expanded headquarters will allow the company to continue its rapid growth and serve its riders and drivers throughout Illinois," says Governor Quinn. Last month, Quinn vetoed legislation that would have put restrictions on companies like Uber in the state. Read more in the press release below.

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.
