Audi CEO's Dieselgate arrest threatens fragile truce among VW stakeholders

FRANKFURT — The arrest and detention of Audi's chief executive forces Volkswagen Group's competing stakeholders to renegotiate the delicate balance of power that has helped keep Audi CEO Rupert Stadler in office. Volkswagen's directors are discussing how to run Audi, its most profitable division, following the arrest of the brand's long-time boss on Monday as part of Germany's investigations into the carmaker's emissions cheating scandal. The supervisory board of Audi, meanwhile, has suspended Stadler and appointed Dutchman Bram Schot as an interim replacement, a source familiar with the matter said on Tuesday. Schot joined the Volkswagen Group in 2011 after having worked as president and CEO of Mercedes-Benz Italia. He has been Audi's board member for sales and marketing since last September. The discussions risk reigniting tensions among VW's controlling Piech and Porsche families, its powerful labor representatives and its home region of Lower Saxony. VW has insisted the development of illegal software, also known as "defeat devices," installed in millions of cars was the work of low-level employees, and that no management board members were involved. U.S. prosecutors have challenged this by indicting VW's former chief executive Martin Winterkorn. Stadler's arrest raises further questions. Audi and VW said on Monday that Stadler was presumed innocent unless proved otherwise. Munich prosecutors detained Stadler to prevent him from obstructing a probe into Audi's emissions cheating, they said on Monday. Stadler is being investigated for suspected fraud and false advertising. Here are the main factors deciding the fate of Audi. Background: Audi's role in Dieselgate Volkswagen Group was plunged into crisis in 2015 after U.S. regulators found Europe's biggest carmaker had equipped cars with software to cheat emissions tests on diesel engines. The technique of using software to detect a pollution test procedure, and to increase the effectiveness of emissions filters to mask pollution levels only during tests, was first developed at Audi. "In designing the defeat device, VW engineers borrowed the original concept of the dual-mode, emissions cycle-beating software from Audi," VW said in its plea agreement with U.S. authorities in January 2017, in which the company agreed to pay a $4.3 billion fine to reach a settlement with U.S. regulators.

2015 Volkswagen Touareg [w/video]

The second-generation Volkswagen Touareg has been in production since 2010, and is therefore staring down the last part of its model cycle. To keep buyers interested, the company has undertaken a refresh of its upscale midsize SUV. As is typical of these things, the changes include some exterior and interior rejuvenation, as well as increased content levels and a slight uptick in price. The basics of the styling changes are pretty straightforward. The 2015 Touareg can be pretty easily spotted versus the outgoing model by way of its four-bar chrome grille, a cleaner headlight design, bigger VW badge and a completely new lower front clip. (I got one photo of the old and new models side-by-side for my Twitter followers before we rolled out on the drive.) There's also a thin strip of chrome that runs around the bodywork, standard LED taillights and a selection of three new wheel styles and five new paint colors. Inside, I found it harder to spot the changes, old to new. The Touareg's switchgear has been updated and there's a new frame for the infotainment display, but there's no piece that stands out and says "new model year!" Powertrains and mechanical bits all carryover from the 2014 Touareg, too. But there were a few functional changes to the vehicle, primarily in the new Driver's Assistance Package, for me to take note of as I took a lap of my favorite Ann Arbor, MI driving route. Drive Notes Let me start with the newest news then, the Driver Assistance pack. Volkswagen will sell you this suite of safety gear on either the mid-level Lux or the top-end Executive trims, for $2,500. The package included adaptive cruse cruise control, "Front Assist" for emergency braking situations, lane-keep assist and blind spot monitoring. If the contents of that package don't strike you as revolutionary, you're not alone. Some or all of the technologies that are new to the Touareg have been around other showrooms – and other VW family products – for quite a while. Still, they're nice to have as options. All of the driver assistance features that I was able to test worked as advertised, too. The adaptive cruise uses cameras, radar and ultrasonic sensors, so it isn't likely to be impacted by inclement weather, which is nice. I also appreciate that the lane-keep assist (which offers the driver a haptic buzz to the steering wheel when straying out of the lane) can be turned off, or turned down in terms of intensity and reaction time.

VW joins Daimler's protest of new A/C refrigerant as EU deadline for compliance passes

The case of Dupont and Honeywell's refrigerant R-1234yf is doing the exact opposite of keeping things cool. The two chemical companies have spent years and hundreds of millions of dollars developing R-1234yf to replace R-134a, the new refrigerant shown to be 99.7-percent kinder to the environment than the one it is meant to succeed. Part of that development has been years of testing by governments, outside safety agencies and automakers to approve the chemical for use in cars. It passed the protocols necessary for the European Union to declare that new and significantly revised cars from 2013 onward needed to use R-1234yf, and mandated that every car as of 2017 must use it.
Enter Daimler AG. The automaker created a head-on collision test with a B-Class at their Sindelfingen test track that would lead to the pressurized refrigerant being sprayed on the engine. The result in 20 out of 20 test was that the refrigerant burst into flames as soon as it hit the hot engine, while Daimler says that R-134a does not catch fire in the same test. Another unexpected result of the R-1234yf test was the release of hydrogen flouride, a chemical far more deadly to humans than hydrogen cyanide, emitted in such amounts that it that turned the windshield white as it began to eat into the glass.
Said a Daimler engineer in a Reuters piece, "It was scarcely believable. The most complicated lab tests conducted using the most sensitive measuring instruments around found nothing and all we do is drive a car around a couple of times, open a tiny hole in the refrigerant line and the next thing you know the car is on fire." So Daimler said it wouldn't use the refrigerant, and it recalled the cars it had already shipped with R-1234yf.
