German prosecutors have recorded calls between VW bigwigs talking dieselgate

It's barely possible to believe how poorly Volkswagen continues to handle dieselgate. Depending on which day you catch the news, the German carmaker embodies the corporate venality of "Michael Clayton," the comic blundering of the Coen Brothers' "Burn After Reading," and the every-man-for-himself vengeance of "Reservoir Dogs." Today is Tarantino day, with news that German prosecutors have recordings of phone calls between former Audi and Porsche development boss Wolfgang Hatz, ex-Volkswagen Group executive Matthias Muller, and current Porsche executives Oliver Blume and Michael Steiner. Hatz made the calls to the trio in November 2015, two months after Volkswagen admitted its diesel-particulate sins to the U.S. Environmental Protection Agency. Hatz was still employed at the time, and in his company car. Who recorded the calls? His wife. Hatz and his missus apparently saw the storm coming and started stacking defenses early. Hatz's wife, who can be heard encouraging Hatz during at least one call, sent the recordings to Hatz's attorney from her mobile phone. According to a Google translation of the German newspaper Handelsblatt's report, she included the note, "Here is a very long, but quite informative conversation on the current situation with useful formulations." The report in Handelsblatt said that in Germany it is generally "not allowed" to record a conversation and pass it on to a third party. We don't know how the authorities will handle this matter, since prosecutors found the recordings in e-mail attachments on Mrs. Hatz's mobile phone. Remember, when the diesel scandal broke, VW spent months saying that only a small number of low-level personnel were behind it, and all of the higher-ups had been blindsided. Ex-CEO Martin Winterkorn claimed to be "stunned that misconduct on such a scale was possible in the Volkswagen Group." Winterkorn successor Matthias Muller said, "according to current information, a few developers interfered in the engine management." Former VW USA honcho Michael Horn told a congressional committee that "a couple of software engineers" programmed the software for reasons no one could understand. In the recorded conversations, Hatz apparently called Muller to find out how VW planned to treat him.

Volkswagen Jetta getting new 1.4L turbo four

In yet another example of engine downsizing, Volkswagen has announced it is slotting a new 1.4-liter turbo four into the Jetta. The smaller, forced-induction engine will replace the naturally aspirated 2.0-liter four in the Jetta S and the 1.8-liter turbo four in the Jetta SE, bringing with it direct injection and improved fuel economy. The 1.4-liter turbocharged four-cylinder engine is from the EA211 family. It's made of aluminum and features a compact single-scroll compressor, an intercooler integrated into the injection-molded induction pipe, exhaust manifold integrated into the head, variable intake and exhaust valve timing, direct fuel injection, dual overhead cams driven by a toothed belt, and a 10.0:1 compression ratio. All that adds up to 150 horsepower and 184 pound-feet of torque, mated in the Jetta to either a five-speed manual or six-speed automatic transmission. Fuel economy figures have yet to be certified, but are projected to come in at around 39 miles per gallon on the highway with the automatic, representing 13- and 7-percent improvements over the units it replaces. The EA211 is Volkswagen's new global small gasoline engine family, manufactured principally by Skoda in the Czech Republic. It's set to replace the old EA111 series, offering higher efficiency in a more compact and adaptable package. The Jetta Hybrid already uses essentially the same engine paired with an electric motor, and is being adapted to three-cylinder formats as well. INTRODUCTION OF NEW 1.4T ENGINE REINFORCES VOLKSWAGEN'S LEADERSHIP IN TURBOCHARGED, DIRECT INJECTION TECHNOLOGY Aug 4, 2015 Fitment of EA211 engine in Jetta models extends implementation of intelligent downsizing to 97 percent of Volkswagen vehicles sold in the U.S. market Traverse City, MI — Volkswagen pioneered the use of small displacement; highly efficient turbocharged and direct-injection engines in the U.S. Volkswagen first used this combination of turbocharging and direct injection in this market in its TDI® Clean Diesel engines in the Passat in 1996 and extended it into the gasoline field in the 2006 Jetta GLI and GTI models. Since then, the Volkswagen EA888 four-cylinder engine has set the benchmark for small-displacement turbocharged engines, beginning with the 2009 CC, while the EA288 TDI has set the standard for diesel engines in the North American market since it first appeared in the 2009 Jetta TDI Clean Diesel.

To solve diesel problem, VW might need two fixes

Volkswagen says that a fix is on the way for its 11 million vehicles around the globe that are equipped with diesel engine software that can evade emissions tests. The problem might be far more complicated than simply creating a single solution for all of them, though. According to Automotive News citing Reuters, two remedies to cover different NOx-reducing systems could be necessary, and both potentially affect performance. Earlier examples of the EA 189 diesel engine used a lean NOx trap to reduce the harmful material coming from the tailpipe. According to experts in the Automotive News report, a software update might allow the engines to achieve compliance, but that could affect fuel economy. VW already tried this route once before the scandal came to light, but tests by the California Air Resources Board still showed the figures were too high. Later, some of the 2.0 TDI engines began using Selective Catalytic Reduction that reduced NOx by injecting a urea solution into the exhaust stream. According to Automotive News, a software update for this equipment might increase the amount of the substance used. Not only would that mean topping up the fluid more often, but there still could be some reduction in fuel economy. But, since the 2-liter, 4-cylinder TDI engine that sits inside the diesel vehicles first mentioned as being affected by the issue in the US don't have a urea treatment system, VW would need to install them into these cars. VW still hasn't officially outlined its solution (or solutions) to the emissions issue but is expected to soon. The automaker's long-term evasion of regulations with these diesel engines pumped vast quantities of additional NOx into the air. The substance is known to be linked with smog and acid rain. The US Department of Justice is already beginning an investigation into the company, and politicians are pushing for harsh punishments.
