Honda, Mazda, Mitsubishi, Mercedes also under diesel emissions scrutiny

The controversy over Volkswagen's diesel emissions scandal isn't limited to the US. In Europe, where diesel engines are far more popular, the issue is shining a harsh light on the NEDC emissions test. As already known, the evaluation does a poor job of reflecting real-world production of NOx, and it appears a significant number of automakers are affected. The Guardian in the UK has been reporting on real-world test results from a company called Emissions Analytics. After the latest round of checks, vehicles from Mercedes-Benz, Honda, Mazda and Mitsubishi were found to generate far more NOx than they should. The newspaper also published similar results for Renault, Nissan, Hyundai, Fiat, Volvo, Jeep, Citroen, VW, and Audi. On average, the figures are about four times over the limit of producing the pollutant. Unlike VW and its defeat device, these automakers aren't actually breaking the rules. The vehicles perform up to the NEDC lab test for emissions, but those results simply aren't translated to the street. "The VW issue in the US was purely the trigger which threw light on a slightly different problem in the EU - widespread legal over-emissions," Nick Molden from Emissions Analytics said to The Guardian. A big fight to decide the future of this issue appears to be on the horizon. Automakers claim that they can't meet the next round of tightening emissions regulations and are asking for compromises. Although, spokespeople for Mercedes and Honda told The Guardian that the brands would be in favor of the stricter rules. Meanwhile, some European governments began backtracking their support of diesels well before this scandal came to light. The added scrutiny certain hasn't helped the future of the oil-burner.

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.

Ford Mustang Mach-E fails Sweden's moose test

The infamous moose test has claimed another casualty. This time it's the Ford Mustang Mach-E AWD Long Range, which was tested in an electric four-way alongside the Tesla Model Y, Hyundai Ioniq 5 and Skoda Enyaq iV (an electric utility vehicle closely related to the Volkswagen ID.4 that is sold in the United States). According to the Swedish testers at Teknikens Varld, Ford's electric car not only failed to hit the speed necessary for a passing grade, it didn't perform well at slower speeds, either. To pass the outlet's moose test, a car has to complete a rapid left-right-straight S-shaped pattern marked by cones at a speed of at least 72 km/h (44.7 miles per hour). The test is designed to mimic the type of avoidance maneuver a driver would have to take in order to avoid hitting something that wandered into the road, which in Sweden may be a moose but could just as easily be a deer or some other member of the animal kingdom elsewhere in the world, or possibly a child or car backing into the motorway. Not only is the maneuver very aggressive, it's also performed with weights belted into each seat and more weight added to the cargo area to hit the vehicle's maximum allowable carrying capacity. The Mustang Mach-E only managed to complete the moose test at 68 km/h (42.3 mph), well below the passing-grade threshold. Even at much lower speeds, Teknikens Varld says the Mach-E (which boasts the highest carrying capacity and was therefore loaded with more weight than the rest of the vehicles tested in this quartet) is "too soft in the chassis" and suffers from "too slow steering." Proving that it is indeed possible to pass the test, the Hyundai and Skoda completed the maneuver at the 44.7-mph figure required for a passing grade and the Tesla did it at 46.6 mph, albeit with less weight in the cargo area. It's not clear whether other versions of the Mustang Mach-E would pass the test. It's also unknown if Ford will make any changes to its chassis tuning or electronic stability control software, as some other automakers have done after a poor performance from Teknikens Varld, to improve its performance in the moose test.
