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.

Are more diesel scandals about to erupt?

More automakers may soon be embroiled, like Volkswagen, in diesel emissions scandals. According to the Daily Kanban, either the International Council on Clean Transportation (ICCT) or the Deutsche Umwelthilfe (DUH) will soon announce from 10 to 15 more cases of automakers cheating national diesel emissions rules. The outlet says three of the incidents are attributed to Opel. Studies conducted by the DUH, the University of Applied Sciences in Bern, Switzerland, and the UK's Leeds University found that Opel's diesel Zafira, Corsa, and Vectra models emit more NOx than European regulations allow when tested in ways that go beyond the European testing protocol, such as when done on a four-wheel rolling road instead of a two-wheel rolling road. Opel said the accusations had no merit. Specifically on the Zafira, the DUH asked Opel about the emissions findings, and Opel said that no General Motors software contains any measures to enable cheating. Opel then tested a Zafira of its own "both on a two- and a four-wheel roller dynamometer," finding that "The emission behavior determined in each case does not differ from one another." That makes this a case of he-said-she-said for the moment. The Daily Kanban's sources say the cheating methods "range from the crude to the highly sophisticated," with those at the latter end complex enough to render Volkswagen's methods "pedestrian." As for any automakers who might be named, the matter of real-world emissions exceeding a legal limit doesn't mean a carmaker has designed systems that cheat, it might mean the company designed the car to pass a test.

Take a listen to the Volkswagen ID 3 and Koenigsegg Jesko

What could better demonstrate our diametric vehicular future than sound clips of the Volkswagen ID 3 and the Koenigsegg Jesko? Battery-electric vehicles don't make enough noise on their own, so VW partnered with composer Leslie Mandoki for the legally-mandated Acoustic Vehicle Alerting System (AVAS) that warns pedestrians and cyclists of the EV's presence. Mandoki — a German-Hungarian who once played drums in a Euro disco band called Dschinghis Khan — was asked to come up with a sound for the ID 3 that VW said "defines its identity," "radiates safety and the promise of effortless mobility," and that "must also impress with its unique character." The definition of the ID 3's single-motor, 201-horsepower character is this: Occupants and people around the hatch can hear the sound as the car accelerates to 18.6 mph, and when reversing. At higher speeds, the sound of wind resistance and tire noise takes over. As our library of AVAS tones grows, it's clear that EVs will provide a soundscape as varied as that of internal combustion engines. Here, for instance, is the industrial thrum used as the Karma Revero GT's pedestrian warning: And here is the sci-fi soaring from the BMW Vision M Next, as composed by Hans Zimmer: At the other end of the aural chamber, we have the Koenigsegg Jesko. In this case, the composer is a 5.0-liter twin-turbo V8 running on a bio-ethanol E85 blend that's almost suitable for IndyCar, powering the engine up to 1,600 horsepower. Output on pump gas will be 'only' 1,281 hp. The Swedish automaker released a clip of the exhaust note of a car in progress inside the Angelhom factory.

To paraphrase Sesame Street, though, one of these sounds is definitely not like the other.
