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.

Mitsubishi Shogun Sport SVP Concept is the offroad Mitsu we want

The Mitsubishi Shogun Sport SVP Concept just debuted at the Commercial Vehicle Show in the U.K. For those unaware of the Shogun Sport's origins, it's a Mitsubishi Triton-based SUV with truck-like off-road capability. This concept raises the bar for what's possible with this big SUV when the terrain gets rough. Mitsubishi and some aftermarket suppliers have given the truck some impressive modifications. For one, it has a 40 mm wider track and new offroad suspension. Walkinshaw Performance Limited and Koni both helped with new components and the suspension tuning. BF Goodrich all-terrain tires wrap new Predator 18-inch off-road wheels with a red outer rim design. Then to give the sides of the Shogun Sport more clearance while rock crawling, Mitsubishi fitted raised side steps finished in black. Other trail-ready add-ons include the big LED light bar and rally-style PIAA driving lamps on the grille. Mitsubishi has changed up the design a bit by adding a new colored grille, massive decal package and a big hatch lid badge. The interior gets a few new bits like heavier bolstered seats, red LED mood lighting and special patterns used throughout. Of course, we don't get the Shogun Sport in the United States. This concept happens to use Mitsubishi's 2.4-liter turbo-diesel four-cylinder, which makes 181 horsepower and 317 pound-feet of torque. Mitsubishi has recently talked about a return to trucks in America, but nothing certain is in the pipeline for now. Meanwhile, we just got our first look at Mitsubishi's smallest new crossover yesterday, the 2020 Outlander Sport.

Japan plans real-world diesel emissions test after companies fail

Japan's transport ministry plans to start real-world diesel emissions tests after an experiment found four models from Toyota, Nissan, and Mitsubishi that produced more nitrogen oxide (NOx) emissions than the nation's rules allow, according to The Japan Times. Regulators there usually only perform emissions checks in the lab. The VW diesel scandal has everyone double-checking their figures. Diesel versions of the Toyota Hiace van, Land Cruiser Prado, and Nissan X-Trail produced up to 10 times more NOx than allowed. The Mitsubishi Delica D:5 was up to five times over the limit, The Wall Street Journal reports. There was no evidence of defeat devices in the vehicles. Mazda performed well in the experiment, though. The CX-5 passed with nearly the same results on the road and in the lab. The Demio, better known as the Mazda2, did nearly as well with only slighter higher figures in the real world than in the controlled setting. The experimenters theorized the reason for the excessive emissions was that cold weather caused the engines' software to shut off the exhaust gas recirculation to prevent damage, according to the WSJ. However, this behavior also increased NOx production. Toyota, Nissan, and Mitsubishi don't have to worry about punishment from the transport ministry because this check was just an experiment. Their models already passed the mandated lab tests, which was the only requirement, according to The Japan Times. As governments begin greater real-world emissions tests, the results suggests diesels aren't very clean. A recent check in France found models from Ford, Renault, and Mercedes-Benz that didn't perform up to the standards. Regulators in India conducted similar evaluations and ordered VW to recall over 300,000 vehicles. Related Video:
