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.

Mazda returns to rotary with RX-Vision Concept, crowd goes wild

Rotary! Forget everything for a second. Ignore the sleek styling, formed-by-wind sheetmetal, outrageously rear-drive proportions, and general ridiculousness of the sideview mirrors. And please be so kind as to ignore the poorly lit photos here – Mazda has a thing for drama. Concentrate instead on one fantastic phrase from the concept car press release: "next-generation Skyactiv-R rotary engine." The crowd here in Tokyo was downright frothing to get a look at the new concept car – hoping to catch a glimpse of the first evolutionary stage for a RX-9 sports car. The critical factor in that effort is of course the rotary engine. Mazda says that, while production of the powerplant is "on hold," the company has "never stopped research and development towards the rotary engine." The fact that the company has named the new engine gives us great hope that it exists in reality, and will be available for sale at some future date. The devil is in the details though, and there are precious few available at the Mazda stand. Other than a brief history lesson about Mazda's racing heritage, and fuzzy-vision talk about the future, we only have expectations to feed on. Oh, there's also a tiny press release, below. Related Video: HIROSHIMA, Japan—Mazda Motor Corporation unveiled the rotary-powered Mazda RX-VISION sports car concept at the Tokyo Motor Show*1 today. The rotary engine is a symbol of the company's "never-stop-challenging" spirit. RX-VISION represents a vision of the future that Mazda hopes to one day make into reality; a front-engine, rear-wheel drive sports car with exquisite, KODO design-based proportions only Mazda could envision, and powered by the next-generation SKYACTIV-R rotary engine. Rotary engines feature a unique construction, generating power through the rotational motion of a triangular rotor. Overcoming numerous technical difficulties, Mazda succeeded in commercializing the rotary engine, fitting it in the Cosmo Sport (known as Mazda 110S overseas) in 1967. As the only automaker to mass-produce the rotary engine, Mazda continued efforts to improve power output, fuel economy and durability, and in 1991 took overall victory at 24 Hours of Le Mans with a rotary engine-powered race car. Over the years, the rotary engine has come to symbolize Mazda's creativity and tireless endeavor in the face of difficult challenges. While mass production is currently on hold, Mazda has never stopped research and development efforts towards the rotary engine.

Mazda Hazumi concept gets punchy, comes out of its corner early

The official images Mazda Hazumi concept, which previews the next-generation Mazda2, have leaked out from Chinese website Auto.sohu.com ahead of its debut at the 2014 Geneva Motor Show.
The subcompact, four-door hatchback shows off Mazda's Kodo design language in its smallest size yet. Hazumi means "bound" or "spring up" in Japanese, and it is meant to look like it is packed with energy. It is a very attractive little concept and hopefully points to a more stylish face for the next-generation Mazda2.
Mazda has not unveiled the full details about the concept yet, but in a previous release, it said for the car is using a 1.5-liter Skyactiv-D diesel engine. While Mazda has not officially said that the Hazumi shows the next Mazda2, it did say in its earlier release that it "points the way to the future" for the brand's small cars. Reading between the lines isn't too difficult, then.
