VW internal investigation finds 'no evidence' against suspended engineers

Volkswagen is still working out the chain of events that led to emissions-evading software being installed in 11 million diesel vehicles worldwide and deciding who was responsible for the treachery. So far, the German automotive giant's internal investigation hasn't publicly named many suspects, and three suspended executive-level engineers have been found not to be culpable in the wrongdoing, according to an anonymous insider speaking to Reuters. VW knows that the software began being installed in the EA 189 engine in 2008. The internal investigation has found that the emissions-evading tech was created because the powerplant was found to fail US standards. Plus, the diesel mill wasn't meeting cost targets, according to Reuters. The automaker responded by suspending over 10 employees, but three top engineers among them might not have been involved. Those put on leave include Heinz-Jakob Neusser from VW, Ulrich Hackenberg from Audi, and Wolfgang Hatz who led Porsche's research and group-wide engine development. The internal detective work hasn't turned up any evidence against these three men. In addition to VW's own inquires, government investigators in both the US and Germany are taking a serious look into the company's actions, too. So far, the automaker is setting aside about $7.3 billion to pay to fix the vehicles with the evasive software. Depending on what authorities find, the costs could grow quickly. Beyond the financial implications, the scandal has led to a serious shakeup in VW's corporate structure. Related Video:

VW announces reworked 6.0 W12 TSI engine

Nobody makes more engines with a dozen cylinders than the Volkswagen Group. They're W12s, of course, owing to the novel shape of their cylinder banks. Now the German industrial giant has announced a comprehensively reworked version of that engine at the same Vienna Motor Symposium where it presented its new 2.0-liter turbo four. The new W12 retains the same arrangement and the same 6.0-liter displacement, but updates it all with the latest powertrain tech. In place of Audi's FSI direct injection and Bentley's TMPI multi-point injection, the engine has adopted a new TSI system. It's also got a pair of new twin-scroll turbochargers, APS-coated cylinders, a new cooling system, active engine mounts, cylinder deactivation, and a stop/start system. And – crucially for application in the upcoming Bentayga – it has an oil circuit designed for off-road use. The revised package now produces 600 horsepower and 664 pound-feet of torque. Considerably more than the 567 hp and 516 lb-ft offered in the Bentley Continental GT W12, but less than the GT Speed, which we suspect will get an even more powerful version of this new engine. It's also more powerful than even the top version of Audi and Bentley's 4.0-liter twin-turbo V8, to make the W12 a more compelling option. Of course that's just as far as the Continental GT is concerned. The W12 has also found use in the Continental GTC and Flying Spur, as well as the Volkswagen Phaeton and Audi A8, and could find further applications under the Flying B emblem and elsewhere in the future. VW says that in the right application (say, in the production version of the Bentley EXP 10 Speed 6 concept, for example), the new twelve-pot could deliver 0-62 times of under four seconds and a top speed in excess of 186 miles per hour. Volkswagen at the 36th International Vienna Motor Symposium Dr. Heinz-Jakob Neusser: "The car of the future will continue to fascinate people" - CO2 reduction, electromobility and digitalisation are the greatest challenges facing the automotive industry - The future of the internal combustion engine will be characterised by high rpm diesel and high-performance three-cylinder TSI engines - Laser roughening – innovative coating process in large-scale production - New 6.0 W12 TSI with 447 kW (608 PS) – performance and refinement - New generation of EU6 TDI engines for light-duty vehicles Dr.

Audi A8 could spawn Mercedes-Maybach S600 rival

Five years ago, there was no middle ground for big luxury sedans. You either bought a $100,000 Mercedes-Benz S-Class, Audi A8, or BMW 7 Series, or you spent $225K on a twelve-cylinder Bentley Continental Flying Spur. But today, the market is changing. Bentley sells a V8-powered Flying Spur for around $200,000 and Mercedes is successfully selling a longer, twelve-cylinder, ultra-lux S-Class for $190,000. The middle ground is growing, and Audi wants in on the action. Audi is looking closely at the Mercedes-Maybach S600, according to Dr. Stefan Knirsch, the company's new technical leader. The company recently introduced a one-off A8 limo, shown above, although we'd imagine an S600 rival would be a more manageable size. "We are thinking about it," Knirsch told AutoExpress at the launch of the new SQ7. "The success of the extra-long version of the S-Class has got us wondering about whether there could be a business case for that in the future." Knirsch's comments raise a number of questions about a potential ultra-lux A8. Would it be longer than the A8L? The extra backseat space is a key part of the Maybach S600's appeal. What about the badge? Audi doesn't have a nameplate to rival Maybach to distinguish such an exclusive A8 from its more affordable siblings. Will the Audi offer more or fewer shades of black/silver than the S600? But the biggest question is what a bigger, more luxurious A8 could mean for the rest of the A8 range. As AE explains, Mercedes has done a remarkable job of fleshing out the S-Class range, with the normal sedan, Maybach, Coupe, Cabriolet, and their accompanying AMG variants. The Maybach S600 started that process – could an extra-large competitor kickstart Audi's full-size luxury expansion? The A8 has long been subject to gossip that it'd spawn an A9 Coupe (2014's Prologue Concept only fed that particular rumor mill), after all. Beyond hinting at a more luxurious A8, Knirsch expounded on another piece of exciting news: the next A8 will get Level 3 automation. That would mean full driverless ability "with the expectation that the human driver will respond appropriately to a request to intervene," according to the SAE's official definition. While Audi confirmed last year that the A8 could drive itself at speeds up to 37 miles per hour, Knirsch's more specific comments make it sound like the system could be even more advanced than originally thought.
