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 forced to sell stake in Suzuki

The six-year-long failed marriage between Volkswagen and Suzuki has finally come to an end. Almost. An arbitration panel in London issued its final verdict which, according to a VW press release, cleared Suzuki in terminating the agreement, so VW now needs to get rid of its 19.9-percent share. However, the tribunal's decision said VW performed all of its obligations and Suzuki didn't – the Japanese carmaker should have given VW last-call rights for a delivery of diesel engines, but failed to. The breach opens Suzuki up to damage claim, but so far VW only says it reserves the right to sue. Now that Suzuki has an outside investor to provide funds it meant to get from VW, perhaps both can get back to their reasons for being. The press release is below. Ruling in arbitration proceedings: Cooperation between Volkswagen and Suzuki deemed terminated - Arbitral tribunal confirms Volkswagen met contractual obligations and finds that Suzuki has ordinary right to terminate agreement based on reasonable notice - Volkswagen to dispose of its 19.9 percent stake in Suzuki and expects positive effect on Company's earnings and liquidity from transaction - Arbitrators also find that Suzuki breached its contractual obligations to Volkswagen under the agreement and that Volkswagen has right to claim damages Wolfsburg, 30 August 2015 - An arbitral tribunal in London has announced its ruling in the dispute between Suzuki Motor Corporation and Volkswagen Aktiengesellschaft. As a result, cooperation between the two parties is deemed terminated. The arbitrators confirmed that Volkswagen met its contractual obligations under the cooperation agreement and found that Suzuki has terminated the agreement upon reasonable notice. Volkswagen will therefore now dispose of its 19.9 percent stake in Suzuki and expects a positive effect on the Company's earnings and liquidity from the transaction. The arbitral tribunal also confirmed that Suzuki breached its contractual obligations to Volkswagen under the agreement and that Volkswagen has the right to claim damages. "We welcome the clarity created by this ruling. The tribunal rejected Suzuki's claims of breach and found that Volkswagen met its contractual obligations under the cooperation agreement. Nevertheless, the arbitrators found that termination of the cooperation agreement by Suzuki on reasonable notice was valid, and that Volkswagen must dispose of the shares purchased.

Ex-Fiat exec: VW diesel scandal will hurt plug-in hybrids

It doesn't sound right at first blush, but former Fiat executive and noted diesel-powertrain expert Rinaldo Rinolfi thinks that plug-in hybrid sales may be more impacted by the VW diesel-emissions scandal than diesel sales. Rinolfi, who worked for Fiat for 40 years, told Automotive News Europe, said that the Euro 6 emissions rules that went into effect in 2015 have already increased diesel-engine production costs enough to raise prices and ultimately flatten demand. By the end of the decade, diesel-vehicle sales will settle in at a 40-percent market share of new European vehicles, and that was going to happen with or without the scandal. "Every carmaker has found ways to achieve fuel consumption and emissions results that have progressively diverged from the real driving conditions." - Rinaldo Rinolfi Makers of plug-in hybrids have more to lose, though, because every PHEV maker has figured out a way to keep emissions figures artificially low, Rinolfi said. Under New European Driving Cycle (NEDC) standards, PHEVs can be tested part of the time with the electric motor in action, meaning emissions get driven down to 30 percent to 40 percent less than real-world figures. With the VW scandal pushing regulators to use real-world figures, those PHEV emissions numbers are expected to rise substantially. To a lesser extent, hybrid emissions figures are also tested as artificially low. "Over the years, even without defeat devices, every carmaker has found ways to achieve fuel consumption and emissions results that have progressively diverged from the real driving conditions the customer experiences," Rinolfi said in the Automotive News Europe interview. Rinolfi is a little sunnier about compressed natural gas (CNG) vehicles, estimating that CNG emissions are as much as 25 percent lower compared to conventional vehicles. As for battery-electrics, he's not so optimistic, estimating that there needs to be at least a tenfold improvement in energy efficiency for EVs to be truly competitive with conventional vehicles. "I've been waiting for a true breakthrough for the past 25 years, but I've not seen it yet," Rinolfi said about EVs in the Automotive News Europe interview.
