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.

Mercedes says it's tops in luxury sales for 2012, not BMW

It turns out that Mercedes-Benz North America has legitimate claim to being the top selling luxury nameplate in the US in 2012.
While sources such as Autodata had put BMW in the top spot, registration data from R.L. Polk shows that Mercedes customers registering new vehicles topped the Bavarian automaker in the most recent calendar year. Polk says Benz posted 274,123 registrations, compared with BMW's 268,498.
In terms of sales posted, BMW had bested Benz 281,460 to 274,134. But sales are recorded somewhat inconsistently from automaker to automaker. Some book the sales as soon as they are shipped from factory to dealer. There is perennial gamesmanship between the two German rivals, and the sales numbers suggest that BMW pushed out some extra sheetmetal to dealers in the last four weeks of the year.

Mercedes-Benz A45 AMG is Affalterbach's first big leap into the little pond

The recent history of AMG is turning out amped-up versions of Mercedes-Benz offerings that would hardly ever be mistaken for their sedate counterparts. Sure, you'd need to pay attention to pick a G-Class from the G63 AMG, but dual side-pipes are a quick giveaway. The Mercedes-Benz A45 AMG is not only a new era in Affalterbach's attention on smaller cars, it is probably also the most subtle transformation we can think of in the line-up.
Low and chunky enough in standard guise to make a sporting impression, the aesthetic makeover is confined to black trim around the lower rim of the hatch, black wheels with red brake calipers and a single, rectangular exhaust tip on either side of the diffuser. It's easier to make a positive ID inside, where the flat-bottomed steering wheel, red seatbelts and red-rimmed details say, "You know what I am..."
If the car is running, though, it won't take but a second. The 2.0-liter turbo spitting 360 horsepower and 332 pound-feet will grumble through a sport exhaust at idle, and bellow through the same on it's way to a 0-60 time of less than 4.5 seconds. And if you need something that looks a little harder - and you want those quad pipes - then the A45 AMG Edition 1 is the treasure you seek. There's a press release below for all the info you'll need until the hot hatch goes on sale in Germany later this year, and photos for the rest of us while we wait to find out if we'll get a chance to buy it.
