Electric turbos promise big performance and efficiency gains in the near future

An electric turbo system boosts efficiency between 15 and 20 percent, according to Audi.
Turbochargers, like acoustic guitars, use moving air to create magic. And electric turbochargers, like electric guitars, provide the ability to amp up that magic to amazing new levels.

Automakers agree to clean up diesels to avoid ban in German cities

BERLIN -- Auto industry officials and politicians in Germany have agreed to clean up diesel vehicles through software updates as part of a rescue plan for avoiding diesel bans in cities, industry and government sources said on Friday. The costs of the rescue plan amount to under 2 billion ($2.33 billion) euros for cars in Germany, with the auto industry agreeing to shoulder the expense of about 100 euros per car, the sources said. After Volkswagen Group confessed to emissions-test cheating in 2015, the entire auto industry has come under scrutiny for producing nitrogen oxide emissions in diesel cars, which are blamed for causing respiratory disease. Audi, a division of Volkswagen Group, said it would update engine software on up to 850,000 diesel cars. The refit of six and eight cylinder engines will be free of charge for all customers, Audi said. The service will also be offered to Porsche- and Volkswagen- branded cars using the same six- and eight-cylinder engines, Audi said. Earlier this week, Porsche's CEO was quoted as saying the brand may abandon diesel engines as its electric cars go to market, and Mercedes announced a plan similar to Audi's, in which it will recall 3 million diesel cars in Germany for a $255 million engine software fix. Diesel cars from all domestic and foreign car brands that conform to the latest emissions standards, Euro-6 and Euro-5, will be updated, the sources said. The plan is set to be presented at the beginning of August. With the software updates, the auto industry is able to cut nitrogen oxide pollution by about 20 percent, the sources said. A committee will be set up to measure the impact of updating diesel cars on individual communities and cities, with a view to averting bans of diesel cars, the sources said. Auto industry executives and German Transport Minister Alexander Dobrindt are due to discuss diesel pollution at a summit on Aug. 2.

Audi 3D-printed this tiny Type C racer, we want to drive it

See this little guy? No, not the one driving – that's Professor Hubert Waltl, Audi's head of production and Volkswagen's chief toolmaker. The thing he's driving, though, is a 1:2 scale replica of the 1936 Auto Union Type C. And it was 3D-printed entirely in house. Not in one piece, mind you. It's too big for that. But the Audi Toolmaking division employed metal printing technology to fabricate all the parts that went into this replica of one of the most dominant of the Silver Arrow grand prix racers of the pre-war era. It's essentially like the pedal car Audi rolled out nine years ago, or the E-Tron concept it showed us nearly five years ago. Only this one uses more advanced manufacturing techniques. Aside from making us want to drive it like nobody's business, the half-sized vehicle serves to showcase the advancements which Audi and the VW Group are making in manufacturing – particularly in the area of 3D printing. The German automaker presently has the technology to print laser-melted layers of metallic powder – either steel or aluminum – with grains measuring half the diameter of a human hair. The equipment can handle objects as large as 7.9 inches high by 9.5 inches wide – which, as small as this little car looks, is still a bit too large to simply print out in one piece. Audi Toolmaking prints "Auto Union Typ C" - Exact model of the "Silver Arrow" from a 3D printer - Audi Board of Management Member for Production Prof. Dr. Hubert Waltl: "This underscores our pioneering role in toolmaking." From powder to a component: With a 3D printer, Audi Toolmaking has produced a model of the historical Grand Prix sports car "Auto Union Typ C" from the year 1936. The company is now examining further possible applications of metal printers for the production of complex components. At the same time, Audi is creating important synergies with toolmaking in other parts of the Volkswagen Group. "We are pushing forward with new manufacturing technologies at Audi Toolmaking and at the Volkswagen Group," stated Prof. Dr. Hubert Waltl, Audi's Board of Management Member for Production and Head of Toolmaking at the Volkswagen Group. "Together with partners in the area of research, we are constantly exploring the boundaries of new processes. One of our goals is to apply metal printers in series production." The Volkswagen Group has a total of 14 toolmaking units in nine countries. Under the leadership of Prof. Dr.
