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.

Audi's Project Artemis woes could delay range of VW Group EVs

Two years ago, Audi's then new CEO Markus Duesmann announced his first big initiative called Project Artemis. The plan's marquee component is "to implement a new lighthouse project for Audi in record time," being "a highly efficient electric car scheduled to be on the road as early as 2024" on a brand new platform that would be shared with Porsche and Bentley. An ex-VW and -Porsche man named Alex Hitzinger, who'd also spent time at Apple working on the tech company's electric car, was brought on board to lead Project Artemis and come up with new ideas. Parent Volkswagen Group said it wanted to become "as agile as in a racing team," removing the bureaucratic molasses and bottlenecks interfering with getting the best product on the road in the best time. However, in any grand venture, failure comes before success. Automobilwoche reports that Artemis is struggling through issues large enough to push the product plans back by years. The issue, as it was with the ID.3 lineup on the eve of that car's launch, is software. Well, that's the latest, largest problem; Artemis has already been through copious struggles before getting to the software bit. Two months after Hitzinger came on, in December 2020, VW raised its EV volume target from 50% to 70% by 2030. That necessitated a rethink of the VW Group's entire platform strategy considering the far greater production scale. Hitzinger only lasted six months in the job, ousted in May 2021, supposedly because Audi believed his ideas were "not suitable for profitable series production" among other reasons. By that time, the pace of software development was already said to be six months behind schedule, with the Car.Software division working on VW.OS 2.0 "not yet running at the speed hoped for." Internal frictions were noteworthy and costly as well. VW's commercial division plant in Hanover was meant to build Artemis vehicles for Audi, Porsche and Bentley, but Automobilwoche reported in January of this year that Porsche paid a ""small three-digit million amount" — like $100 million or so — to get out of the deal mandating its vehicles come from the Hanover facility.    So Audi effectively brought Artemis in-house to lead vehicle development, and Car.Software turned into Cariad to get VW.OS and VW.AC, which stands for Automotive Cloud, to market.  The first Audi vehicle under Project Artemis was planned to arrive by the end of 2024, a production version of the Grandsphere concept.

How VW's hyper-efficient XL1 will influence the next Golf

In 2007, the European Union mandated fleet average CO2 emissions of 158.7 g/km. For 2015, that figure will drop to 130 g/km, and the target for 2020 is an ambitions 95 g/km. Thanks to some German politicking, that target will be phased in from 2020 to 2024, but it will still apply to 80 percent of passenger cars in that first year. In US miles per gallon, that's the equivalent of going from about 35 mpg to 42 mpg to 57 mpg. The current Volkswagen Golf is rated from 85 g/km of CO2 to 190 g/km depending on model - and zero for the e-Golf, so for the next-generation MkVIII hatch due in 2019, to meet the goal, Volkswagen engineers will need to introduce a bunch of new tricks. According to a report in Autocar, VW be mining its hyper-efficient XL1 for some of them.
Predictions for the next Golf include a variable-compression engine, an electric flywheel and an electric turbo, along with taking greater advantage of coasting. Volkswagen could be getting help from Audi with the electric turbo and variable-compression engine and electric turbo, with Audi already having shown off the former and brand technical boss Ulrich Hackenberg confirming the VW Group is working on the latter. It's possible the flywheel system could also have the mark of The Four Rings: Autocar mentions a British system that Volvo is testing, but the R18 e-tron Quattro racer has been using one for years.
The need for such features is because the company won't be able to net enough future gains from just aerodynamic improvements and advanced materials. As price will be a factor (the regulations are expected to "add hundreds of euros to the cost of building a car"), adding much more aluminum or carbon fiber is an unlikely option. We're told the next generation won't be longer or wider than the current car, and being Europe's most popular model, VW doesn't want to make a big bet on futuristic aero, but the report says the MkVIII will "likely" have "the most aerodynamic treatment yet seen on a production vehicle," the area where lessons learned from the XL1 will truly be seen.
