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.

Ousted Renault CEO Bollore raised concerns over Ghosn investigation

PARIS — Renault's former chief executive Thierry Bollore, who was ousted in October, had sought to flag alleged conflicts of interest and governance problems at the company's Japanese alliance partner Nissan before his departure, Le Monde reported on Monday. Citing a letter from Oct. 7 addressed to Nissan's board, of which he was member, France's Le Monde newspaper said Bollore had raised questions over the firm's internal investigation surrounding former alliance boss Carlos Ghosn. Nissan and Renault were left reeling by Ghosn's arrest in Tokyo a year ago, on financial misconduct charges which he denies. They have since tried to reboot their strained partnership by revamping their management teams, including by purging them of Ghosn allies and removing people in top jobs at the time of the scandal. Bollore — who took a step up at the French carmaker when Ghosn left even though he was known for his close ties to the alliance founder — was eventually pushed out as Renault's CEO on Oct. 11, days after penning his letter. In comments sent to Reuters, Nissan spokeswoman Azusa Momose denied there were any irregularities in its internal investigation of Ghosn's affairs, and added that the company had reviewed its processes once again following Bollore's letter. "Nissan's independent directors confirmed that the investigation was properly conducted and could be relied on," Momose said. Nissan directors had discussed all the allegations raised by Bollore and the company "concluded that Bollore's concerns were not founded and were based for the most part on inaccurate information and speculation," she added. Bollore said in the letter that he was particularly concerned by the revelation that Nissan had a list of 80 managers implicated in financial dealings similar to the ones attributed to Ghosn. He also raised issues with the chain of command at Nissan, saying some key board members were sometimes kept in the dark on internal matters. Renault, which is still searching for a permanent replacement for Bollore as CEO, had no immediate comment. As well as changing its CEO, Nissan recently demoted senior vice president Hari Nada — a key whistleblower against Ghosn and whose role was also questioned in Bollore's letter — although its internal investigation had found no evidence against the executive.

Car theft skyrockets thanks to rising parts prices

Cars and trucks today have achieved a high level of average quality, with safety and technology features that keep occupants safer than ever and meet consumers' high expectations. But the National Insurance Crime Bureau finds that those components come with a rising price tag, leading to expensive repair bills — and rising vehicle thefts to support a thriving black market for parts. The nonprofit NICB said it looked at the cost of replacement parts for the top 10 stolen 2016 models, with average OEM part prices pulled from a database of more than 24 million vehicle damage appraisals generated for 2016 and 2017 insurance claims. The list did not include major components like engines or transmissions, only easily-stripped components like bumpers, doors, hoods and headlights. It found that: The 2016 Toyota Camry, which had a used market value of around $15,000, had 15 commonly replaced parts that added up to almost $11,000, not including labor, with quarter panels alone costing almost $1,600 a pair and a set of alloy wheels tallying more than $1,600. The Camry was also the top stolen vehicle in 2016 at 1,113 thefts. A 2016 Nissan Altima had 14 standard parts worth more than $14,000, including a single headlamp assembly that costs just over $1,000. The Altima was the second-top stolen vehicle in 2016 at 1,063 vehicles stolen. And the 2016 GMC Sierra pickup, which was No. 7 on the 2016 top-stolen list, rang up $21,000 from 20 standard components, including an $1,100 headlamp assembly and an $1,100 rear bumper. "For the professional theft ring, stealing and stripping vehicles for parts has always been a lucrative business," Jim Schweitzer, NICB's senior vice president and chief operating officer, said in a statement. "On today's cars and trucks, the parts are often worth more than the intact vehicle and may be easier to move and sell. That's why we see so many thefts of key items like wheels and tires and tailgates ... there's always a market for them." Check out the NICB infographic below. Vehicle thefts in the U.S. rose by more than 4 percent in 2017, based on preliminary FBI data, after rising 7.6 percent in 2016, though the overall trend has been down since vehicle thefts peaked in 1991, according to the NICB.
