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 promises 141 mpg, no door dings [w/video]

I'm the president of Autoblog's chapter of the Citroën C4 Cactus Appreciation Club. Full Disclosure: I'm also probably its only member. Why am I fan, you ask? Because the C4 and its ding-resistant Airbumps offer the versatility of a five-door Ford Focus, but it's 350 pounds lighter than today's Mazda MX-5 Miata, tipping the scales at just over 2,100 pounds. And when equipped with a diesel, it returns 91.1 miles per gallon (European), all while looking like the epitome of French quirkiness and style. I can't think of anything not to like about it, aside from the fact that I haven't actually driven it (Citroën, call me, we can change this).
For the 2014 Paris Motor Show, Citroen is bringing a new concept version of the Cactus. Unlike the Adventure Concept shown at the Geneva Motor Show earlier this year, the Airflow 2L Concept is focused on increasing the Cactus' already impressive fuel economy. Through a fanatical observance of aerodynamics and the shedding of a further 220 pounds of weight, the Airflow 2L Concept returns over 141 miles per gallon (in other words, it consumes just two liters of fuel per 100 kilometers, hence the "2L" in the name).
Aerodynamic drag has been reduced by 20 percent thanks to three adjustable intakes in the front fascia, which can open and close automatically based on driving conditions. Side deflectors divert air around the body while active shutters on the 19-inch wheels further cut down on drag even further. The old concept car trope of video cameras in place of traditional wing mirrors is present, ostensibly to further reduce drag, while Citroën has added an air curtain system on the front bumper to manipulate air around the wheels.

Citro?n C4 Cactus production model keeps it weird and bumpy [w/video]

This is the new Citroën C4 Cactus, and it's what you get when you combine the designs of a Land Rover Range Rover Evoque and a Jeep Cherokee with a hint of woodie wagon. This is a fascinating and thoughtful little package, even if you aren't attracted by its appearance.
The Airbump system (those funny bumps on the doors designed to protect the sheetmetal from dings), which was originally shown on the Cactus Concept, is back for the production model, and will be available in four different colors. Citroën is pushing the customization angle as well, offering ten paint options matched with three different interior treatments.
Citroën isn't yet offering any information on what engines will be available, besides stating that start-stop-equipped PureTech gas engines and BlueHDi diesel will be featured, but it does offer some interesting metrics. Fuel economy and emissions for the diesel model sits at 91.1 miles per gallon on the European cycle and 82 grams of CO2 per kilometer, making it both exceptionally clean and fuel efficient. The gas engine, meanwhile, promises under 100 grams of CO2 per klick. While there's no doubting that this is down to a thrifty powertrain, Citroën's focus on weight reduction plays a big role as well.
