Ford and Mercedes join Renault in French emissions investigation

The French government is investigating certain models from Ford, Mercedes-Benz, and Renault because they allegedly produce more nitrogen oxide than the country's pollution rules allow, according to Automotive News, citing a French newspaper. After VW's emissions scandal, French regulators began checking more vehicles for evidence of defeat devices and excessive real-world pollution. According to Automotive News, the Mercedes S350 allegedly showed inconsistent results across these tests, and a Ford C-Max had NOx levels five times over the limit. The Renault Captur crossover, Espace, and an unnamed utility vehicle also had results that were too high. The French testing for this investigation includes an on-road emissions check that's not part of the EU's normal evaluations, which some automakers claim is unfair. "Unofficial on-road testing has varying conditions and can produce significantly different results," a Ford of Europe spokesman told Automotive News. Renault representatives met with French officials on January 18 to explain the situation. The company later submitted a plan to recall 15,800 examples of the diesel Captur, and said it would offer a voluntary software upgrade for about 700,000 other vehicles, according to Automotive News. Representatives from Ford and Mercedes will meet with the government soon, too. Renault's stock price plunged last week after investors heard that French regulators searched three of the automaker's sites as part of the emissions investigation. The stockholders feared an environmental scandal like the one currently embroiling Volkswagen. There's one major difference – as of now, there's no evidence Renault equipped any of the polluting models with defeat devices. Related Video:

2017 Mercedes-Maybach S650 Cabriolet includes guaranteed exclusivity

For certain buyers, the only thing better than a super-luxurious cabriolet that requires enormous sums of money to buy is a a super-luxurious cabriolet that money can't buy. That's what Daimler promises with the 2017 Mercedes-Maybach S650 Cabriolet to be unveiled at the LA Auto Show. Limited to 300 units worldwide and just 75 in the US, having just three available color combinations magnifies the exclusivity. Turning the Mercedes-Benz S-Class cabrio into a droptop worthy of the Maybach family means slight revisions outside and in, and a whole lot of Maybach badges. Instead of the three lower intakes familiar from Mercedes' corporate language, there's black mesh highlighted by a shiny design element. It's not the most graceful face from dead-on, looking sort of like a chrome-lined grimace picked up from Wallace and Gromit. A Maybach emblem adorns the fenders and gleaming kickplates, the 20-inch wheels add an edge to the brand's traditional dinner-plate design. The 6.0-liter, twin-turbo V12 carries over from the donor convertible, with the same 621 horsepower and 738 pound-feet of torque hooked up to a seven-speed automatic transmission. The only three color treatments available in the US will be Zircon Red with a porcelain and black interior and a black top, Cote d'Azur Blue with a porcelain and saddle interior and a beige top, and Designo Diamond White with a porcelain and Yacht Blue interior with a dark blue top. The cabin works nautical themes lifted in part from the Mercedes-Benz Style Arrow 460-Granturismo yacht. Perforations in the leather seats evoke waterfalls. The "Flowing Lines" trim ornamenting the seats comes two different colors depending on the exterior hue; either "Piano lacquer" black with the Zircon Red or Magnolia Nut Brown with the other two options. Buyers will find profuse badging in embroidered, embossed, and inlaid varieties, as well as chrome-plated "1 of 300" lettering in several places like the cup holder and steering wheel. The few lucky customers who buy an S650 will also find a four-piece set of Maybach-badged luggage in the truck, two travel bags and two weekenders tooled up in the same leather as the interior. The key fob gets finished in Porcelain leather. A car cover comes standard, in the same color as the convertible top. A certificate signed by the mustachioed one, Daimler Chairman Dr. Dieter Zetsche, provides the corporate-badged icing on the cake.

These are the 'Greenest' and 'Meanest' cars in 2015

As has become tradition, the American Council for an Energy-Efficient Economy (ACEEE) has come up with a ranking of what it refers to as the "greenest" cars of 2015, and, by way of contrast, a list of the so-called "meanest" cars, so those who value eco-friendliness over all else can choose which vehicles they should or should not consider buying. As you may expect, electric cars make up the majority of the greenest cars on the list, but, perhaps surprisingly to many, the Tesla Model S didn't make the cut. It's worth noting, too, that where the electricity an owner uses to charge their electric vehicle has a big impact on its overall environmental impact. "A car that is charged using electricity generated from natural gas or renewables is going to have significantly less impact on the environment than one charged on a coal-heavy grid," says ACEEE lead vehicle analyst Shruti Vaidyanathan. The ACEEE's list for 2015 looks very different than it did in 2014. It's an interesting collection, though – and we're sure this goes without saying, really – we'd recommend doing a bit more research into each vehicle and how it might fit into your daily life before making any purchase decisions.
