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.

2018 Buick Regal TourX vs. wagon competitors: How it compares on paper

To the great joy of auto enthusiasts nationwide, wagons are back! Well, at least there's a few more of them. The latest is the 2018 Buick Regal TourX, which we just had our first drive of and found to actually be quite good with pleasant handling, solid power and plenty of space. But, how does the TourX compare to other cladded wagons? Well, let's dive into the specs and fire up the ol' spreadsheet maker for Buick Regal TourX vs Subaru Outback vs Audi A4 Allroad vs VW Alltrack vs Volvo V60 Cross Country. True, some are from mainstream brands and others are from luxury marques, but Buick straddles both realms, so it's appropriate to look at them all. Of course, there's more to these cars than just the numbers, but they're still important, and in the case of this class of crossover-aping wagons, can vary more than you'd expect. So check out the specs in the chart below, which are followed by more analysis and photos of each. Discover and compare other wagons and crossovers with our Car Finder and Compare tools. Engines and Transmissions When comparing powertrains, the Buick is far-and-away the winner as far as torque is concerned, and is in a nearly three-way tie for horsepower. Its 295 pound-feet of torque is 22 lb-ft more twist than the next-most-grunty Audi A4 Allroad. And in regards to power, the Buick's 250-horsepower engine is only down 6 hp to the most-powerful Subaru and its optional naturally aspirated flat-six, and just 2 hp less than the Audi. At the bottom of the pack is the Subaru Outback with the standard naturally aspirated flat-four, which only makes 174 hp and 174 lb-ft of torque. That may not seem too bad compared with the VW Golf Alltrack, which only makes 170 hp and 199 lb-ft of torque, but the VW is much lighter by between 200 and 300 pounds. Transmission-wise, there's quite a bit of variation in the group. The Regal TourX and the Volvo V60 Cross Country rely on eight-speed automatics, all Outbacks use CVTs, and the Alltrack and Allroad have dual-clutch automated manual transmissions with six and seven gears, respectively. But for people that want to shift for themselves, the only option is the Volkswagen, which offers a traditional six-speed manual transmission on the Golf Alltrack. Cargo and Interior Space One of the main reasons to buy a wagon is for the body style's large cargo capacity. And for the most space for things and stuff, you'll want to check out the Subaru and the Buick.

Audi A7 getting nip and tuck

It's been less than two years since the Audi A7 first went on sale in the US, but European buyers have been able to enjoy the sleek and stylish hatchback for twice as long. As such, Audi is preparing to give its A7 a mild refresh with tweaked exterior styling, but we're also expecting some of the features found in the all-new 2015 Audi A8 to possibly trickle down to the A7.
From what we can tell in these spy shots, the A7 is getting a minor facelift that includes a restyled front fascia and new headlights, which will likely boast Audi's new Matrix LED system. At the rear of the car, similar changes have been made with a fascia that now gets integrated outlets and different taillights that have a Lamborghini-like display.
Not apparent in these images - but still a good bet for production - we'd expect to see the new A7 get some of Audi's updated engines or new driver assist technologies. No definite word as to when we'll be seeing the refreshed A7 in person, but considering how close to production ready as this car seems to be, our bet is on the upcoming Geneva Motor Show.
