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.

U.S. opens probe into whether VW vehicles infringe Jaguar Land Rover patents

WASHINGTON — The U.S. International Trade Commission (ITC) said on Monday it is opening in investigation into whether Volkswagen AG infringed on patents held by Jaguar Land Rover for a system used for off-road driving. In November, Jaguar Land Rover, a unit of Tata Motors, filed a complaint with the ITC seeking to prevent the import of some VW Porsche, Lamborghini and Audi models with "certain vehicle control systems" that allegedly infringe on it patents held for its Terrain Response system. The models include the Lamborghini Urus, Porsche Cayenne and AudiÂ’s Q8, Q7, Q5, A6 Allroad, and E-Tron vehicles and the VW Tiguan. The ITC said it has made no decision on the merits. VW said in a statement it was examining the action and determining its next steps. "We will of course cooperate with investigating authorities. While we cannot comment on any details of the proceedings, we strongly believe that the claims have no merit and will robustly defend our position," VW said. Many automakers offer a suite of off-road powertrain controls, but JLR claims Volkswagen's tech is more than just similar.  Jaguar Land Rover (JLR) said the vehicles "have used JLRÂ’s patented inventions without payment or permission" notably a patent for an "improved system for driving a vehicle on different driving surfaces, in particular off-road." JLR says its Terrain Response technology uses the patented technology to maximize performance on off-road driving surfaces, including grass, snow, mud, sand and rocks.

Volkswagen preparing Tiguan Coupe R

Volkswagen has might proliferation plans for the SUV side of the VW brand, Autocar listing a range that will comprise seven models and variants on sale by 2018. The next-generation Tiguan will play a large part in tripling VW's crossover lineup, a development discussed a year ago, with a standard model, the three-row long-wheelbase version to be built in Mexico, and a five-door "Coupe" variant that will get an R version worked up by the in-house R team. The Tiguan Coupe R is aimed at the performance end of the compact crossover field, giddyup coming from a 2.0-liter four-cylinder with something like 300 horsepower and 280 pound-feet of torque that works through a six-speed dual-clutch transmission. Underpinnings are expected to be cribbed from the Golf R; a hotter suspension tune with a lower ride height and four-mode damping. The sprint to 62 miles per hour would clock in around 5.1 seconds, and handling nous would be aided by all-wheel drive and electronic torque vectoring. It will need all of that in order to catch up to the competitive set listed by Autocar of the 375-hp Mercedes-AMG GLA45, 309-hp Audi RS Q3, and potential Range Rover Evoque SVR and BMW X2 M. The CrossBlue Coupe seen in Shanghai earlier this year will provide the styling cues, we're told, with rakish glass front and back, and thick C-pillars supporting a leaner greenhouse. We'll likely see the basic Tiguan at next month's Frankfurt Motor Show, then will come the long-wheelbase in 2016, the regular Coupe in 2017 along with the Touareg and US-built CrossBlue, then in 2018 the Tiguan Coupe R, CrossBlue Coupe, and Nissan Juke-fighting T-Roc.
