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.

Audi bringing new TT Roadster to Paris

The TT may be first and foremost a coupe, but in presenting the third-generation model, Audi has toyed with all sorts of body-styles. There's been the prototypical coupe, of course, but also shooting brake and crossover concepts. The one thing it hasn't shown us is the convertible model, but that ends today as Audi takes the wraps off the new TT Roadster and TTS Roadster.
Set to be unveiled at the Paris Motor Show next month, the new TT Roadster naturally follows its fixed-roof counterpart's lead closely, but with the addition of a folding fabric roof mechanism. Made of magnesium, aluminum, steel and plastic, the mechanism weighs 6.6 pounds less than its predecessor's, helping keep the center of gravity lower. It also folds flatter to allow for more luggage space, and can deploy or retract in ten seconds at speeds up to 31 miles per hour. With the roof up it's also quieter, and with a drag coefficient of 0.30, Audi claims it's the slipperiest in the segment.
Of course, Audi's also worked to keep the weight down and rigidity up. As a result, the 0-62 sprint only takes an extra 0.2 seconds, quoted in the TTS Roadster at 4.9 seconds instead of 4.7 in the TTS coupe. Top speed remains pegged at 155 miles per hour. That, of course, is with the top-spec, 310-horsepower 2.0-liter turbo four, but Audi will also offer the less potent 184-hp version as well as a 2.0-liter TDI, mated to either a six-speed manual or six-speed DCT, though specific performance figures for each version were not disclosed in the press release below.

Recharge Wrap-up: Smart metals, OTA updates, Rolls-Royce LNG ship

"Smart" metals could help engines reduce emissions and invigorate US business. Metallurgist and University of Wisconsin – Milwaukee professor Pradeep Rohatgi combines known metal alloys with materials like ceramics, nanoparticles, and recycled waste to produce strong, lightweight composites with self-lubricating properties that help internal combustion engines run more efficiently. Rohatgi hopes his startup, Intelligent Composites, and its products can help US foundries compete with production outsourced overseas. See the video above, and read more at Phys.org. Almost 203 million cars will be capable of over-the-air (OTA) updates by 2022, according to ABI research. While Tesla has the OTA firmware updates nailed down, other automakers will focus on software update capability. This will take the place of dealer-installed updates and - like Chrysler did after the Jeep hacking incident - updates sent to owners via USB drives. OTA updates will enhance vehicle security and reduce recall rates. Read more at Green Car Congress. European bus manufacturers have agreed upon a standardized charging interface for their electric buses. Irizar, Solaris, VDL and Volvo will use pantograph charging for "opportunity charging" and CCS plugs as the base for overnight charging and network communication. The manufacturers hope other bus makers and charging providers to join them in cooperation over standardized charging. Read more at Green Car Congress. The second Audi Autonomous Driving Cup will take place from March 22 to 24, 2016 at the automaker's Museum Mobile in Ingolstadt, Germany. The competition involves eight university teams implementing basic Audi software in 1:8 scale electric Audi Q5 models, and putting them through the paces of simulated real-world driving situations. The teams develop software architecture to use the suite of sensor to have the cars drive, park, maneuver in traffic and perform emergency braking autonomously. Teams also perform a freestyle event where they put the car through an additional task of their choosing. The winning team gets ˆ10,000, with smaller prizes for second and third place. The competition also gives the students the opportunity to showcase their skills in front of a potential employer. Read more at Green Car Congress. Rolls-Royce will provide the Liquefied Natural Gas (LNG) propulsion for an NSK cargo ship carrying fish food. The ship will deliver 2,700 metric tons of fish food to fish farms along the Norwegian coast.
