Audi starts new e-gas partnership with Global Bioenergies

Audi continues to try to build its green-car cred with one more partnership to produce synthetic fuels made from renewable resources. The German automaker is hooking up with France-based Global Bioenergies to make a synthetic biofuel called e-gasoline. Audi says making this e-gas "does not create competition with food production and farmland," nipping that argument in the bud. Last summer, Audi opened a power-to-gas facility in Werlte, Germany. That factory produces hydrogen and synthetic methane, which are made from renewable energy sources such as water and excess carbon dioxide. The E-gas plant uses electrolysis to split water molecules into oxygen and hydrogen; those elements will later be set aside to power fuel-cell vehicles but in the near term, the plant will make synthetic natural gas. Audi started delivering e-gas in Germany in the fall of 2013 and estimated that it would make enough of the stuff each year to power 1,500 Audi A3 Sportback G-tron vehicles for more than 9,000 miles. Audi also operates a research facility in Hobbs, New Mexico, with renewable fuel company Joule. That plant produces e-ethanol and e-diesel. Check out Audi's press release about its new Global Bioenergies partnership below. Audi launches strategic partnership with Global Bioenergies Premium carmaker and biotechnology company developing the drop-in biofuel Audi e-gasoline Reiner Mangold, Head of Sustainable Product Development: "Another step closer to carbon-neutral mobility with Global Bioenergies" e-gasoline part of the big Audi e-fuels strategy Audi is launching a strategic partnership with Global Bioenergies. The carmaker will work with the French biotechnology company to promote the development of non-fossil fuels. In addition to the Audi e-gas and e-diesel projects, the research into e-gasoline is part of Audi's persistent efforts to find alternative fuels. Reiner Mangold, Head of Sustainable Product Development at AUDI AG: "We're taking another step closer to carbon-neutral mobility with our partners at Global Bioenergies. We are supporting an innovative technology here which can be used to produce renewable fuel. This process does not create competition with food production and farmland." e-gasoline is part of the overall Audi e-fuels strategy. Audi is already operating a research facility for the production of e-ethanol and e-diesel with its partner Joule in Hobbs, New Mexico. The Audi e-gas plant in Werlte began feeding into the grid a few months ago.

Feds allege widespread Volkswagen cheating on clean-air rules

Volkswagen intentionally installed software in nearly a half-million diesel vehicles that helped the cars evade substandard results on emissions tests, the federal government charged Friday. The Environmental Protection Agency issued a notice of violation to the German automaker, saying the company's software broke the law by violating two provisions in the Clean Air Act. Circumventing the standards meant affected cars emitted as much as 40 times the allowable level of certain pollutants. Both the EPA and California Air Resources Board have launched investigations. In its notice of violations, the EPA said Volkswagen officials admitted to installing and concealing what they call a "defeat device," which was designed to detect when the cars were undergoing official emissions tests – and only turn on emissions controls during that time. "Our goal now is to ensure that the affected cars are brought into compliance, to dig more deeply into the extent and implications of Volkswagen's efforts to cheat on clean air rules, and to take appropriate further action," said Richard Corey, executive officer of CARB. The allegations cover approximately 482,000 vehicles sold in the United States over the past seven years. Cars involved include diesel versions of the Jetta, Beetle, Audi A3 and Golf manufactured between the 2009 and 2015 model years. Passats manufactured for the 2014 and 2015 model years are also included. Federal officials note there is no safety danger to motorists, but the cars will be recalled for repairs. If true, Volkswagen faces a fine that could run in the hundreds of millions of dollars -- likely higher than the $300 million charge the EPA levied last November at Hyundai and Kia for exaggerating the fuel-economy in several models. The charges also put a tremendous dent into the company's plans to increase sales of its "Clean Diesel" vehicles in North America. In a written statement, Volkswagen Group of America acknowledged it had received the notices from the EPA and CARB. "VW is cooperating with the investigation; we are unable to comment further at this time," it said. Federal officials said the defeat-device software was uncovered during an independent analysis by researchers at West Virginia University, who in working with the International Council on Clean Transportation, a non-governmental organization, raised questions about emissions levels.

Audi reveals 'rightsized' 2.0 TFSI engine for next A4

Downsizing engines is a trend sweeping the industry. It's not a new thing, and downsizing helps automakers cut fuel consumption and emissions while employing techniques like turbocharging and direct injection. Audi, however, is taking a different approach with its latest engine. Revealed at the Vienna Motor Symposium in Austria is Audi's newest trick powertrain. Where others are going with smaller engines, Ingolstadt's latest displaces a nice round 2.0 liters, employing a shorter intake time to use less fuel. It's sort of like the Miller cycle that Mazda brought to market on the old Millenia, only turbocharged (instead of supercharged) and brought up to date. Audi calls the four-pot "rightsized," producing 190 horsepower and 236 pound-feet of torque across a broad rev range, while getting 47 miles to the gallon – and that's on the US cycle, which is tougher than the European standard a company like Audi would usually quote. In short, it's designed to provide power where needed but only sip at the fuel tank when it's not, but the geekiest among us will want to delve into all the intricacies outlined in the announcement below. The engine is set to power the next-generation A4 before being rolled out in additional models in the future. Ingolstadt/Vienna, 2015-05-07 World premiere at the Vienna Motor Symposium: new high-efficiency engine from Audi - New 2.0 TFSI four-cylinder engine with innovative combustion method - Top figures: 190 hp, 320 Nm (236.0 lb-ft), less than 5 l/100 km (47.0 US mpg) - To be implemented in the new Audi A4 by the end of 2015 - Prof. Dr. Ulrich Hackenberg: "A prime example of the Audi rightsizing strategy" Audi presents the most efficient two-liter gasoline engine in its class. The new 2.0 TFSI with 140 kW (190 hp) demonstrates the engine expertise of the brand – with a ground-breaking new combustion method. Audi will be using the engine for the first time in the next generation of the A4. Over ten years ago, Audi was the first manufacturer worldwide to bring the TFSI engine with turbocharging and direct injection into series production. This made the brand with the four rings the trendsetter in downsizing and downspeeding. "We're now taking a crucial step further with rightsizing," said Prof. Dr. Ulrich Hackenberg, Member of the Board of Management for Technical Development at AUDI AG.
