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.

Volkswagen unveils sportier Passat Performance Concept ahead of Detroit debut

Ahead of its official unveiling at next week's Detroit Auto Show, Volkswagen has released some preliminary details and images of its Passat Performance Concept - a car that, as its name suggests, adds a little more spice to the automaker's midsize sedan formula. VW makes no mention of any production intent for this road-ready-looking sedan, simply stating that the Performance Concept is a way to "explore this practical four-door's sportier side."
It certainly doesn't look too sporty, the only visual upgrades being larger 19-inch wheels, dual exhaust, bi-xenon headlamps with VW's Advanced Front Lighting system, LED taillmaps and carbon-look mirror caps. Inside, there are carbon interior accents and two-tone leather upholstery. But no matter, the real upgrades for this mightier Passat are found below the sheetmetal.
Powering the Performance Concept is a 1.8-liter turbocharged four-cylinder engine, churning out 250 horsepower and sending its grunt to the ground via a six-speed automatic transmission. For reference, that's 80 more horsepower than the Passat's base 2.5-liter inline-five, but 20 horsepower less than the potent 3.6-liter VR6. As for other performance upgrades, Volkswagen has fitted the car with a lowered sport suspension and revamped electronic steering, which should indeed add a bit more dynamic feedback to the already nice-driving sedan.
