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.

Weekly Recap: Jaguar takes a leap with price cut, new strategy

Jaguar was one of the famous automotive props and plotlines in the now-iconic drama Mad Men. There's a scene where the show's protagonist, Don Draper, deftly undercuts an influential Jaguar dealer by indicating that get-me-in-the-door local radio spots would be an effective way to sell cars like the slinky E-Type. The British executives think this is folly – Draper knows they will – and his advertising strategy wins out over the dealer's approach to move the metal. Jaguar's not doing that, but half a century later in the real world the company is launching plans to make its cars more attainable to new and younger customers like Millenials. These aren't coupons, but this is a leap for Jaguar, which has long banked on sexy styling and its rich motorsports history to overshadow its past mechanical flaws. Put simply, Jaguar is addressing the reasons why people, especially the younger set, don't buy its cars. The 2017 XE will start at $35,895 when it launches next spring – which makes it an attractive buy for a successful, relatively young person. When it's time to move up, the redesigned XF will be more attainable, coming in at $52,895, which is $5,275 less than the 2015 model. The flagship XJ sedan and the enthusiast-oriented F-Type sports car will also get thousands of dollars worth of added standard features, and Jag is actively pitching them as a better value than their competitors. "The Jaguar brand is on the eve of a major transformation that will see it dramatically increase its presence in the United States luxury marketplace with an expanded lineup, pricing focused on the core of the luxury market, and an all-new ownership package with best-in-class coverage," Joe Eberhardt, CEO of Jaguar Land Rover North America, said in a statement. The brand's quality and reliability dings have also lurked in the back of buyers' minds for decades, though that's an outdated notion. Jaguar placed third in J.D. Power's Initial Quality Study in June and was the top-ranked luxury brand in J.D. Power's Customer Service Index in March. Not content, the company is rolling out an enhanced program called Jaguar EliteCare that launches on 2016 models. It offers a five-year, 60,000-mile limited warranty, the longest among its competitors, with free scheduled maintenance during that period. The plan also covers roadside assistance and connectivity features.

Mercedes Concept IAA shows its mighty morphing aero aids

Modern supercars are utilizing more active aerodynamic elements that constantly adjust, to make them some of the fastest things on the road. The Mercedes-Benz Concept Intelligent Aerodynamic Automobile is using them too, but the know-how is applied here for ultimate efficiency rather than turning better lap times. In the standard design mode, the four-door luxury coupe looks like a CLS from the near future with styling that's mixed with a little of the F 015 concept. However at the press of a button or upon hitting about 50 miles per hour, the IAA transforms into aero mode to have an insanely low drag coefficent of just 0.19. To achieve the ultra-efficient shape, the rear of the concept stretches over 15 inches to guide air down the tail. Flaps in the bumpers also extend outward, and the wheels adjust to improve the flow around the sides. To trim things out underneath, a portion inside the front bumper moves, as well. Inside, passengers sit in organically shaped leather seats, but occupants have to look at a vast array of purple and blue LED accent lights. The big panoramic roof is a nice touch, though. It would be interesting to watch water tumble over this slippery shape when driving in the rain. To maximize efficiency, Mercedes powers the IAA with a plug-in hybrid that's hooked up to a gasoline engine. The result is 275 horsepower and an electronically limited top speed of 155 miles per hour. On the European testing cycle, the company figures the concept could cover 41 miles solely on electric power in aero mode. Showing the gains of the swoopy transformation, that figure falls to 38.5 miles in design mode.
