Mazda3 Skyactiv-Hybrid and CNG Concept shown in Japan

Mazda has received a tremendous amount of public and industry praise in the last few years, following up the successful introduction of its Skyactiv technology (powertrain and otherwise), with strong products like CX-5, Mazda6 and most recently, the Mazda3. At the Tokyo Motor Show, Mazda has taken yet another step forward with Skyactiv and the 3, showing the compact (called "Axela" in Japan) with an all-new compressed natural gas engine in the Skyactiv-CNG Concept.
The end result of the Skyactiv-Hybrid is fuel consumption estimated at something like 74 miles per gallon.
Mazda thinks that CNG-powered vehicles are due for an uptick in demand, and the company believes this new powertrain will add valuable breadth to the Mazda3 range. The CNG Concept is actually a duel-fuel vehicle, capable of running on either natural gas or gasoline. In fact, we're told that the high compression ratio (14:1) inherent in Skyactiv-technology gasoline engines makes conversion to CNG particularly simple.

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.

Alfa Romeo takes Spider in-house, Mazda-Fiat roadster partnership not dead

It's officially off. Following a report in March of this year that the marriage of Mazda and Alfa Romeo to produce a MX-5-based Spider was in trouble, the Italians have confirmed that it will take development in-house. "As far as the Spider goes, the final version is of course no longer the two-seater FCA co-developed with Mazda but a derivative of Project Giorgio," Maserati and Alfa Romeo brand boss Harald Wester told Car. For those not in the know, Project Giorgio is Alfa's codename for the rear-drive platform that will underpin the next-generation Spider, not to mention the replacement for the 159 sedan and a few other products. All is not lost for the Japanese-Italian partnership, though. "The Far East import will probably find a new home with Fiat-Abarth," Wester told Car. Yes, you read that correctly, Mazda is still working with FCA, and the result will eventually end up with Abarth's scorpion badge. If anything, we're more excited over this news than the idea of an Alfa MX-5. But we want to know what you think – would you rather Alfa build a new Spider on the Miata's bones, or does an MX-5 Abarth sound like more fun? Have your say in Comments.
