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.

To solve diesel problem, VW might need two fixes

Volkswagen says that a fix is on the way for its 11 million vehicles around the globe that are equipped with diesel engine software that can evade emissions tests. The problem might be far more complicated than simply creating a single solution for all of them, though. According to Automotive News citing Reuters, two remedies to cover different NOx-reducing systems could be necessary, and both potentially affect performance. Earlier examples of the EA 189 diesel engine used a lean NOx trap to reduce the harmful material coming from the tailpipe. According to experts in the Automotive News report, a software update might allow the engines to achieve compliance, but that could affect fuel economy. VW already tried this route once before the scandal came to light, but tests by the California Air Resources Board still showed the figures were too high. Later, some of the 2.0 TDI engines began using Selective Catalytic Reduction that reduced NOx by injecting a urea solution into the exhaust stream. According to Automotive News, a software update for this equipment might increase the amount of the substance used. Not only would that mean topping up the fluid more often, but there still could be some reduction in fuel economy. But, since the 2-liter, 4-cylinder TDI engine that sits inside the diesel vehicles first mentioned as being affected by the issue in the US don't have a urea treatment system, VW would need to install them into these cars. VW still hasn't officially outlined its solution (or solutions) to the emissions issue but is expected to soon. The automaker's long-term evasion of regulations with these diesel engines pumped vast quantities of additional NOx into the air. The substance is known to be linked with smog and acid rain. The US Department of Justice is already beginning an investigation into the company, and politicians are pushing for harsh punishments.

VW Beetle R is one mean bug

Volkswagen's R lineup currently consists of the Golf R in North America, and the too-cool-for-school Scirocco R in Europe. It hasn't exactly been a secret as to which VW would next get the R treatment; the German manufacturer reportedly confirmed that a hotter Beetle would be coming to the US. That announcement, in August 2011, was followed up by a production-ready Beetle R Concept at the 2011 Frankfurt Motor Show.
After some wait, we're finally seeing spy shots of the Beetle R in Germany. The mule shown in the images here is wearing the R-Line bodykit, which adds sportier front and rear fascias, side skirts, dual exhausts and a not-so-subtle spoiler. Topped off with Volkswagen's traditional, five-spoke R wheels, we'd be just fine with the Beetle R coming to market as is.
Our spy photographer, though, seems to think that the production R will get even sportier sheetmetal, which we take to mean the more assertive look shown on the Frankfurt show car. Larger intakes on the front fascia, a bigger rear spoiler and vertical vents on the rear bumper could all be upcoming. Whether a production model will include the concept's polished wheels (R cars haven't traditionally embraced that look), vented hood and the quad-tipped exhausts remains to be seen.
