New info on how VW, Porsche, Audi V6 TDI engine cheat works

The German newspaper Bild am Sonntag is reporting that US investigators have found three pieces of software that work in concert to turn off the emissions control equipment in certain diesel models after a set period of time. The engine in question, the 3.0-liter TDI turbodiesel, was found in certain Volkswagen Touareg, Audi Q7, and Porsche Cayenne models – the sale of which was suspended in the US late last year. Since most emissions compliance testing takes around 20 minutes, the software in the three VW Group models shuts off the emissions control equipment after 22 minutes, a straightforward end run around the testing. Remember that the 3.0-liter TDI engines aren't included in the big buyback and recall program announced for the smaller 2.0-liter, four-cylinder TDI engines. The 3.0-liter engines will likely get their own program, but we don't know when to expect it or exactly what it will look like. Last month, California rejected a proposed fix for the larger TDI engines, and VW went back to the drawing board. Since the company is unlikely to create two fixes, one for California and one for the rest of the nation, the company can't really proceed until they figure out a solution California will accept. The EPA hasn't officially commented on the report, and we don't know how Bild am Sonntag came across the information, but we'll be closely watching what emerges after this report. Related Video:

Skoda launching two new CNG-powered vehicles in Europe in June

Skoda's second- and third-ever production compressed natural gas (CNG) vehicles aren't exactly speed burners, but they are efficient. The Czech automaker, which is owned by Volkswagen, will introduce its Octavia G-TEC and Octavia Combi G-TEC models to most of Europe next month. Skoda's first CNG model was the Citigo, which debuted in 2012. The Octavia models will have a turbocharged 1.4-liter engine that will deliver about 109 horsepower. Quickness isn't these cars' virtue, as their 0-60 mile per hour acceleration time will be almost 11 seconds. But they can go as far as 826 miles on their tanks of gas and CNG, enough to go from Prague to Rome in one shot, in case anyone was curious. Or nuts. The move by Skoda makes sense, as the CNG market in Europe has long been far further along than it is on this side of the pond, where CNG has primarily been used to move delivery trucks, but it's now available in pickups form Chrysler, Ford and General Motors as well as passenger cars from Chevy and Honda. The Skoda Citigo has moved almost 2,000 units since its debut, with 1,300 vehicles sold last year alone. That car can go as far as 385 miles on CNG and gasoline combined, which is impressive but not quite as bladder busting as the Octavia models. Check out Skoda's press release below. SKODA continues its CNG offensive with the new SKODA Octavia G-TEC Launch of the new SKODA Octavia G-TEC and new Octavia Combi G-TEC in June First SKODA Octavia with natural gas drive as standard; 97 g CO2/km High-performance technology: bivalent turbo engine 1.4 TSI/81 kW The ultimate in fuel economy: up to 1,330 km with natural gas and petrol SKODA Citigo G-TEC has enjoyed market success since 2012; only 79 g CO2/km Natural gas is the environmentally-friendly, cost-effective alternative Mlada Boleslav, 19 May 2014 – Expanding its environmentally-friendly model range, SKODA is renewing its emphasis on compressed natural gas vehicles. The new SKODA Octavia G-TEC and the new SKODA Octavia Combi G-TEC will be given their market premiere in June. This will increase the brand's CNG range to three models. Since the end of 2012, the little natural gas-drive Citigo has been successfully touring the European markets. "With the new Octavia G-TEC and the Octavia Combi G-TEC, our model range is becoming even more environmentally-friendly," says Dr Frank Welsch, SKODA Board Member for Technical Development.

US prepares to sue Fiat Chrysler over diesel emissions testing

NEW YORK - The Justice Department plans to file a civil lawsuit against Fiat Chrysler Automobiles NV over excess diesel emissions as early as this week if no agreement is reached with the Italian-American automaker, two sources briefed on the matter said on Wednesday. The Environmental Protection Agency in January accused FCA of illegally using undisclosed software to allow excess diesel emissions in about 104,000 cars and SUVs, the result of a probe that stemmed from regulators' investigation of rival Volkswagen AG. The EPA and California Air Resources Board have been in talks with FCA about the excess emissions and whether the agencies would approve the sale of 2017 FCA diesel models. A federal judge in California has set a May 24 hearing on a series of lawsuits filed by owners of vehicles against Fiat Chrysler and the Justice Department is expected to file its action by then if no agreement is reached. FCA said on Wednesday it believed that any litigation would be "counterproductive" to ongoing discussions with the EPA and California Air Resources Board. The company added that "in the case of any litigation, FCA US will defend itself vigorously, particularly against any claims that the company deliberately installed defeat devices to cheat U.S. emissions tests." The Justice Department took the same procedural step in early 2016 against Volkswagen, nearly four months after the German company admitted using software to emit excess diesel emissions in nearly 500,000 vehicles. The Justice Department has had an ongoing criminal investigation into FCA's conduct since last year, Reuters reported in January. The probe has turned up internal emails written in Italian and other documents about engine development and emissions issues, sources briefed on the probe said. U.S. regulators said FCA failed to disclose engine management software in 104,000 U.S. 2014-2016 Jeep Grand Cherokees and Dodge Ram 1500 trucks with 3.0-liter diesel engines. The European Commission has launched legal action against Italy for failing to respond to allegations of emission-test cheating by Fiat Chrysler in a procedure that could lead to the country being taken to court. The EPA has said the maximum possible fine against FCA could be $4.6 billion. In February, FCA said it had received requests for information and subpoenas from U.S. federal and state authorities, including the Securities and Exchange Commission, for diesel issues.
