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:

2014 Mercedes-Benz S-Class interior caught in spy shots

With the redesigned 2014 Mercedes-Benz S-Class getting closer to production, the camera-wielding crew over at Autospies somehow managed to get inside of the car to snap some detailed spy shots. As the prototypes continue to shed camouflage, it would appear that Mercedes-Benz is getting closer to unveiling the car, and with the Geneva and New York auto shows coming up, it could be sooner rather than later.
From what we can see of this car's interior, the overall look of the S-Class' cabin isn't a ground-breaking departure from the current car, but it has been completely redesigned with more advanced technology. The styling is now even more upscale with larger swaths of wood, more shapely door panels (without the built-in armrest cubbies) and the concept-like two-spoke steering wheel. The highlight of this car though is probably the two massive digital screens with one being used for driver information and the other used for navigation, audio and infotainment systems. One other detail we noticed about this car is that it was equipped with the new 360-degree camera that debuted on the new GL-Class and will also be used on the 2014 E-Class. We also know that the next-gen S-Class will be getting the new cloud-based MBrace2 infotainment system.
As for the exterior design, it looks like the next S-Class will carry a similar profile as the current car, but we can see through the camouflage that the new styling will fit in better with current Mercedes-Benz products. Up front, the grille is much larger is flanked by aggressive LED-trimmed headlights, while the rear view of the car shows us the LED brake light now at the top of the rear window, a more pointed trunk opening and a more squared-off rear fascia with exhaust outlets pushed to the corners.

Why it's difficult to accurately test the efficiency of a plug-in car

When it comes to electric vehicles and plug-ins in general, the Environmental Protection Agency-certified range is a hugely important number. While actual range anxiety is largely psychological, the magic number does provide a point of comparison of buyers considering one EV over another. The driving distance is also often touted by automakers when marketing their models. Unfortunately, as Green Car Reports finds in a recent deep dive, the way the EPA calculates the figure is a convoluted mess, and discovering the reasons why is definitely worth the read. The issue isn't about bad science but instead comes down to vague wording. The EPA's accepted range test is sourced from an evaluation called J-1634 from the Society of Automotive Engineers, and it seems to provide balanced results for vehicles that automatically reach a single state of charge when plugged in. However for models with multiple charge settings, the situation gets complicated very quickly. Of course, these modes are often created in the software, meaning that a car's certified driving distance can change with just a few taps of the keyboard without the real world results owners might experience actually changing. By showing the test's effects on the certified range for the Tesla Model S, Nissan Leaf and Mercedes-Benz B-Class Electric Drive over the last few years, Green Car Reports makes a compelling argument that it's the evaluation that needs to change. Thankfully, it appears that the solution is a very simple one. Get the details here.
