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.

Race recap: 2015 Singapore Grand Prix full of odd sideshows

What greeted the Formula One teams in Singapore? Confusion. The haze was so thick that observers wondered if the race would be held at all. Then practices began, and Mercedes-AMG Petronas driver Nico Rosberg took the first one, but the team fell away after that. Mercedes said it couldn't get the tires turned on, but no one believed the Silver Arrows was in genuine trouble. Then qualifying set the confusion in stone. Ferrari driver Sebastian Vettel laid down the best time in Q3, taking the team's first pole position since Germany in 2012. Daniel Ricciardo got his Infiniti Red Bull Racing into second, about one tenth behind Vettel. (That may make the team feel better after Ricciardo publicly asked for a better engine than the current Renault unit, and team advisor Helmut Marko said the outfit will quit F1 at the end of this year if it can't get a stronger powerplant for 2016.) Kimi Raikkonen put the second Ferrari in third, Daniil Kvyat put the second Red Bull in fourth. And only then came the Meredes'. Lewis Hamilton's best got him fifth, the Brit saying, "We don't really know what we have got wrong. For some reason the tires are not working on the car. We do the warm-up the same as everyone else and then you see someone one second up the road." For added emphasis on the reversal of fortune, his time was 1.6 seconds behind Vettel's. Teammate Rosberg is next to him in sixth, a further half a second back. Williams is still a hurting a bit on slow tracks, so Valtteri Bottas could only get into seventh ahead of Max Verstappen in the Toro Rosso and teammate Felipe Massa in ninth. When the red lights went out, the 2015 Singapore Grand Prix would get both less interesting and more interesting all the way to the final lap. The men up front got good getaways, and the order into Turn 1 was Vettel, Ricciardo, and Raikkonen. The race finished with those three in that order, never having conceded position. Vettel's Ferrari enjoyed the track so much that he laid a second per lap into Ricciardo for the first five, then relaxed. He'd let the gap come down later in the race a couple of times, but any time he wanted to see what his mirrors looked like without anyone in them he'd take off again. Rosberg took fourth position after holding down sixth for the first stint. It looked like he'd have an even worse day - for a Mercedes driver - when he had problems getting his car started and onto the grid before the race.

Race recap: 2015 British Grand Prix is a testament to timing

In front of his home crowd, Lewis Hamilton actually had to work for pole position at the British Formula One Grand Prix. The World Champion couldn't get on top of the setup for his Mercedes-AMG Petronas on Friday, lapping behind teammate Nico Rosberg and the two Ferraris. Come Saturday, after a few alterations and a whole lot of wing to clamp down on understeer, Hamilton returned to his regular program at the front, taking pole position by just over a tenth of a second from his teammate. Williams, thought to be headed for another stretch in the weeds a few races ago, showed its best strength all year. The Grove team got both cars on the second row and in front of the Ferraris, Felipe Massa qualifying ahead of teammate Valtteri Bottas, but they were eight and nine tenths behind the Mercedes'. Kimi Raikkonen out-qualified Ferrari teammate Sebastian Vettel for the second time this year, and only the first time in a straight-up battle with two healthy cars. But more than a second behind the two cars at the front, and with two nearly-impossible-to-pass Williams' in front, neither the Finn nor the German is happy with where they are. Daniil Kvyat claimed seventh, his side of the garage at Infiniti Red Bull Racing having got through the weekend to that point without a single complaint about their Renault power unit. Carlos Sainz, Jr. put a single Toro Rosso inside the top ten in eighth position, ahead of Nico Hulkenberg who did the same for Sahara Force India by slotting in ninth. The second Infiniti Red Bull driven by Daniel Ricciardo did have an unspecified engine complaint – his car kept "bleeding power" on the straights – but even so he managed to qualify tenth with his second-fastest lap. The stewards deleted his best lap because he ran three centimeters outside the track limits at Copse, an infraction that stung a few other drivers as well. Up in front, what would sting the Mercedes-AMG Petronas drivers the most was the start. That's when a dearth of grip struck both Hamilton and Rosberg, allowing Massa and Bottas to slide right up the middle between them and take the first two places. The leapfrogging was so surprising that it looked like the Mercedes drivers were giving the Williams drivers a head start. They diced through the first corners, Hamilton sliding past Bottas into second place halfway through the lap. And then the safety car reported for duty.
