Next Audi RS4 to get an electric turbo?

We don't yet know if the next Audi RS4 will come to the US, but whoever gets it could find an electric turbocharger under the hood according to a report in Auto Express. The 4.2-liter V8 that has served for two RS4 generations is retiring from the line, replaced by a twin-turbocharged version of the supercharged 3.0-liter V6 used in the S4. But instead of using two sequential turbochargers - a smaller one to eliminate lag while a larger, more powerful turbo spools up - batteries charged by brake regeneration could power a first-stage electric turbo. The idea hasn't been publicly appointed for a particular model, as Audi's technical chief Ulrich Hackerberg has said that due to expense, that kind of setup "would only be used be used on the very top end models." Since the technology cuts down on the use of exhaust gases, it would also also help in markets like Europe where CO2 emissions are a factor. No matter whether it benefits from all conventional or some electric boost, the horsepower number for the twin-turbo V6 will be more than 420 hp but less than 503 hp, the rating of the V8-powered Mercedes-Benz C63 AMG. Auto Express believes Audi will want to maintain the power gap between the 333-hp S4 and previous, 444-hp RS4. With Hackenberg saying the new S4 will make more than 350 hp, that gets the coming RS4 up to at least 461, but AE figures it "could deliver as much as 480 hp." We'll find out sometime after the S4 launches next year.

Audi workers are frustrated with 'disastrous' indecisiveness of top management

FRANKFURT (Reuters) - Audi's management board, including Chief Executive Rupert Stadler, has been sharply criticized by company managers, Bild am Sonntag reported on Sunday, citing an internal dossier. It said the executive board had shown no signals of a fresh start, change or readiness for the future, and that workers were frustrated with "disastrous" indecisiveness. Stadler has come under fire for how he has handled the fallout from parent company Volkswagen's diesel emissions scandal. Munich prosecutors have been investigating Audi on suspicion of fraud and criminal advertising in the United States, where the Volkswagen scandal broke in September 2015. Stadler only got a five-year contract extension last month because of an agreement among supervisory board members that he would not serve out his full term, two sources close to the company's supervisory board have told Reuters. An Audi spokesman said: "We deny plans to get rid of Stadler," adding that he declined to comment on the content of the dossier. Volkswagen is looking at rehiring the chief executive of General Motors' Opel, possibly to lead Audi, a source familiar with the matter told Reuters this month, following his resignation from Opel. Bild am Sonntag also quoted Oliver Blume, the head of Porsche, Volkswagen's sportscar division, as saying he had no interest in replacing Stadler. "I have a dream job and am very happy at Porsche. Nothing else comes into question for me." (Reporting by Georgina Prodhan; Editing by Nick Zieminski) Related Video:

Audi builds 5-millionth vehicle with Quattro

Quattro, the trademark name Audi has put on its all-wheel-drive system engineered for passenger vehicles, recently celebrated its five-millionth installation. The driveline has been offered in more than 140 different vehicles since its introduction more than three decades ago.
The all-wheel-drive technology made its world debut at the 1980 International Geneva Motor Show, beneath the floorpan of the Quattro Coupé, a low-volume two-door. It didn't take consumers long to embrace Audi's innovative approach. While most four-wheel-drive systems at that time utilized heavy transfer cases or second cardan shafts, Quattro was virtually tension-free, light, compact and efficient. Most importantly, enthusiasts found it was especially suitable for sports cars.
Today, the automaker offers Quattro on its full line of passenger vehicles and it is unquestionably successful (the technology enjoyed a 43 percent take rate in 2012). On models with transverse-mounted engines (A3 and TT), Audi uses an electronically controlled multi-plate clutch with hydraulic actuator. Under normal conditions, the clutch sends power almost exclusively to the front wheels (if wheel slippage occurs, up to 100 percent of the torque may be sent to the rear). Vehicles with transverse-mounted engines (A4, A5, Q5, etc...) use a self-locking center differential sending 40 percent of the engine torque to the front axle and 60 percent to the rear under normal conditions (it is able to send the majority of the power to the axle with better traction when needed). The highest-performing Quattro systems use torque vectoring to further improve cornering grip and speeds.
