French probe alleges 2 million PSA cars had engine cheats

PARIS — A French investigation into alleged emissions cheating by PSA Group found that suspect software had been used on almost 2 million vehicles sold by the maker of Peugeot and Citroen cars, Le Monde reported on Friday. Paris-based PSA denies any use of fraudulent engine software, a spokesman said in response to the newspaper report, which sent PSA shares sharply lower. The stock was down 4.4 percent at 17.78 euros as of 1019 GMT. So-called "defeat devices" restrict exhaust output of toxic nitrogen oxides (NOx) under regulatory test conditions while letting emissions far exceed legal limits in real-world driving. In February, PSA became the fourth carmaker to be referred to French prosecutors by the country's DGCCRF watchdog over suspected emissions test-cheating, after Volkswagen, Renault and Fiat Chrysler. PSA's engineering chief acknowledged at the time that emissions treatment in the group's diesels was deliberately reduced at higher temperatures to improve fuel efficiency and carbon dioxide (CO2) emissions in out-of-town driving, where NOx output is considered less critical. According to Le Monde, an internal PSA document obtained by DGCCRF investigators includes discussion of the need to "make the 'defeat device' aspect less obvious and visible." However PSA insists there is nothing fraudulent or illegal about its engine calibrations. "PSA denies any fraud and firmly reaffirms the pertinence of its technology decisions," the company said on Friday.

Citroen C4 Cactus Airflow 2L brings the fuel-sipping funk [w/video]

Full disclosure: I love the Citroën C4 Cactus. Really, I just love French automakers. Kudos to them for flexing their design muscles, creating products that compete in the mass market while not looking like anything else on the road. This C4 Cactus, for example - it's a small hatchback that's about the same size as a Ford Focus, designed to take on small crossovers like the (also weird) Nissan Juke and Renault Captur. But it looks radical, what with its funky Airbump door trim (think of it as aerodynamic, protective Braille), extensive and imaginative color palette, and decidedly weird styling. It's just plain cool.
This specific C4 Cactus, however, takes things a step further with a massive focus on emissions and fuel economy. Much like the Peugeot 208 with which it shares a powertrain, the Cactus 2L Airflow uses PSA Peugeot Citroën's Hybrid Air powertrain, comprised of a three-cylinder PureTech gasoline engine and a compressed air storage unit. There are three different operating modes for the Hybrid Air system, including "air power," where the compressed air motor runs things, "petrol power," which is pretty self-explanatory, and "combined power," where the combustion engine works with the compressed air system to move things along.
The end result? A five-door hatch that weighs just 2,100 pounds (you know, lighter than a Mazda Miata) and is capable of getting 141 miles per gallon on the European cycle, or two liters per 100 kilometers (that's why it's got "2L" in its name). And it's all wrapped in colorful, textured, uniquely French package. Sign me up.

Touch but don't look at Citro"en's new Cactus concept [w/video]

Citroën isn't telling us much about its concept for Frankfurt this year. All we know is that it's called the Cactus, and its nose in profile looks like the image above. That, and it's got some kind of special bumpers on it that are apparently filled with air to absorb shocks. Whether those are there to protect the doors from dings, the body panels from shopping carts or the structure from crashes, we don't know, but something tells us it's not the latter.
The French automaker plans on revealing more on September 5, just a few days before the show opens, so we'll have to wait until then. But in the meantime you can watch the brief, quirky and typically French clip below.
