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.

FIA levels F1 playing field for Honda

Formula One may place a high emphasis on technical innovation, but it also demands an equal playing field. So after the FIA regulations handed Mercedes a technical advantage for next season, a loophole was opened up to allow Ferrari and Renault to update their engines throughout the year. That left engine-supplier-to-be Honda in the dust, but now the motorsport governing body has awarded the Japanese automaker the same courtesy. As is often the case, the issue revolves around the specific wording of the regulations. Ferrari and Renault successfully argued that, contrary to its spirit, the letter of the law (or regulations, in any event) didn't actually specify when existing engine suppliers had to complete their revisions for the upcoming championship. The thing is that the rules were more clear when it came to new suppliers, so Honda was told that it would have to complete its design before the start of the season – unlike Ferrari, Renault and Mercedes, which would be allowed to continue development (albeit on a limited basis) throughout the year. Recognizing the inherent injustice of the resulting regulations, the FIA has consented to Honda's request that it be afforded the same opportunities as its rivals. The Japanese manufacturer, which returns to the paddock this season with McLaren, will therefore be allowed to make adjustments to its engines as its first season back on the grid progresses, just like the other engine suppliers.

Red Bull F1 denied access to Honda engines

There are four engine manufacturers in Formula 1: Ferrari, Honda, Mercedes-Benz, and Renault. Infiniti Red Bull Racing ended its marriage to Renault, got to the altar with Mercedes and then Mercedes backed out, couldn't even agree on a pre-nup with Ferrari, and Honda flat-out said, "No." At the moment that has left the four-time World Champions without an engine for next year, owner Dieter Mateschitz threatening to take his two teams and four cars out of the sport, and F1 honcho Bernie Ecclestone threatening to sue Mateschitz if he does. The Japanese company had turned down the idea because after a first year with some poor performances and a few public sour notes, it wants to get McLaren's cars running properly before it expands its operation. Now it seems some behind-the-scenes action of late has opened up channels between Red Bull and Honda, and the two are at least talking. Honda, though, still says such a deal is highly unlikely at best, and Red Bull says it will have something to say when something is done. It appears that McLaren chief Ron Dennis, however, has vetoed the idea. Ecclestone says Honda made a deal with the FIA that would allow Honda to supply two teams in its second year, but Honda gave Dennis veto rights over who the second team would be. For the same reason that Mercedes backed out and Ferrari only wanted to sell Red Bull year-old engines, Ecclestone says Dennis might view Red Bull as a competitor and doesn't want to risk two more cars getting in front of his own. If that's the case and Red Bull is going to remain in the sport, it might need to hit the flower shop and book a trip to Renault headquarters. Soon. Related Video:
