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-Benz cut fleetwide emissions by 4.3 percent last year

Mercedes-Benz says it reduced its fleetwide vehicle emissions by 4.3 percent last year. Of course, the German automaker has another 29 percent to go to meet the European Commission's 2020 mandate. But who's counting? Mercedes' luxury and sports car bent has made it a relative laggard when it comes to increasing fleetwide fuel-efficiency, but the company did reduce emissions from 140 grams of CO2 per kilometer to 134 last year. The company's fleetwide fuel efficiency (calculated using the lenient European standard) was 5.4 liters per 100 kilometers, which equals about 44 miles per gallon and represents a 25-percent jump since 2007. Benz has come a long way from its gas-swilling V8 tanks of the 1970s. In fact, the company said its top performer, in the fuel-efficiency sense, was the diesel-powered B180 CDI BlueEfficiency Edition, which consumes 3.8 liters per 100 kilometers. That equals about 62 mpg (again, on the lenient scale). The company got some additional good press by revealing that Winfried Kretschmann, Minister-President of the German State of Baden-Wurttemberg, drives a Mercedes-Benz S300 BlueTEC Hybrid. Not exactly a Nissan Leaf, mind you, but it's a start, as is the company's efforts to bring its fleetwide emissions ever closer to the 95g CO2/km level that the EC is mandating by 2020. Take a look at Mercedes-Benz's press release below. Minister-President of the German State of Baden-Wurttemberg, Winfried Kretschmann (left), with Prof. Dr. Thomas Weber (right) and a Mercedes-Benz S-Class S 300 BlueTEC HYBRID Fleet fuel consumption for Mercedes-Benz Cars falls to 134 g CO2/km: Top efficiency figures in all vehicle classes Stuttgart, Apr 08, 2014 Benefit for the environment and customers: In almost all vehicle classes, Mercedes-Benz offers the most efficient vehicle in the competitive lineup. Moreover, in 2013 the company was able to reduce the fuel consumption and CO2 emissions[1] of the Mercedes-Benz Cars EU new vehicle fleet by a further six grams, to 134 g CO2/km. This means that in 2013, the average fleet consumption was 5.4 litres/100 km – a reduction by 24.7 percent since 2007. At present the company offers more than 50 models emitting less than 120 g CO2/km and 71 models emitting less than 130 g CO2/km. Customers can find vehicles in the Mercedes-Benz model range that consume considerably less fuel than competing models. "With our model initiative we want to be the leading premium manufacturer by 2020 again, says Prof.
