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:

The Mercedes-Maybach Pullman Guard is a limo with a bulletproof vest

As fabulously plush as the Mercedes-Maybach Pullman is, there is a certain class of individual for which luxury is only part of the equation. Oligarchs, dictators, kingpins of questionable businesses, and probably some legitimate world leaders all love luxury, but they sometimes face some hairy commutes that demand a bit more protection. For them, the answer to their luxury car needs is the armored Pullman Guard. The Mercedes-Maybach Pullman Guard tops the line of S-Class Guard models that also includes the Mercedes-Benz S600 Guard and the Mercedes-Maybach S600 Guard. Like the non-armored Pullman it packs loads of leather, seats with practically infinite adjustability, and redundant gauges for rear passengers. It is also by far the longest S-Class vehicle available, stretching more than 40 inches longer than the next-longest Mercedes-Maybach. This tremendous length allows the Pullman Guard to have four-passenger seating in the rear, with two seats facing two others. It's the perfect place to sign treaties or entertain diplomats. Or, if foreign affairs aren't your speed, it would also be a convenient place to carve up territory, issue ultimatums to enemies, and intimidate dissidents. The Pullman Guard was developed alongside the standard Pullman, and because of that, the added armor does not sacrifice interior space. The armor does affect weight, though. The Pullman Guard weighs over 11,000 pounds. But, in return, the steel plates on the sides and floor, non-Kevlar-brand high-strength fabrics, and polycarbonate-backed windows protect occupants from bullets and explosives. Plus, the Pullman Guard features a twin-turbo V12 that produces 530 horsepower and 612 lb-ft of torque to haul the added ballast around. If a recognized authority is ordering a Pullman Guard, Mercedes also offers sirens, flashing lights, two-way radios, an emergency starter battery, and a loudspeaker system. These items are sure to be useful when trying to navigate seas of protestors in the streets. All of this extra protection will cost you though, and if you have to ask, you definitely can't afford it. But we'll tell you the price anyway. A standard Pullman will run around $500,000 at current exchange rates. For the Guard model, be prepared to shell out about $1.56 million. It's a steep price for sure, but for those whose pampered lives are in danger, it's probably worth it.

Mercedes-AMG could use electric turbos

Mercedes-Benz is joining Audi in analyzing electric turbochargers for its production cars. But while Ingolstadt will roll out its first e-turbo in its A8 luxury sedan, Stuttgart is studying the technology for use in small performance cars, like the A45, CLA45, and GLA45 AMG models. Auto Express spoke to Mercedes-AMG compact car boss Steffen Jastrow about the cutting-edge tech, which reduces turbo lag, improves fuel economy, and occupies less space under the hood than a standard turbo. "Of course we need more power for the next-generation of cars, but electrification does not mean we have to use an electric drivetrain." Jastrow said. "They have to be faster and e-turbos are an option. We use them in motorsport, but the technology has to be payable for the customer." As AE tells it, bringing the price of e-turbos down from the A8's luxury car level to the relatively affordable sums demanded by compact AMG models will still take some time. So don't count on seeing a Mercedes with an electric turbocharger until the new A-Class arrives in 2017, at the earliest. Related Video:
