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.

Audi also calling in A8, S8 over sunroof issue

The S6 and S7 (apparently prone to potential fuel leaks) aren't the only Audis being recalled currently, as a separate recall notice has been issued for its flagship A8 luxury sedan and its high-performance counterpart, the S8.
The problem apparently revolves around the glass sunroof, which is fitted as standard and which is reportedly prone to break. The National Highway Traffic Safety Administration determined that not only could the falling shards themselves end up injuring the vehicle's occupants, but could also distract the driver enough to cause a crash. As a result, Audi's American wing is bringing in all 2013 and 2014 model year A8s and S8s - 1,120 units in all - to have their glass sunroofs replaced free of charge.

Audi RS3 Sedan coming to America with over 400 hp?

The Mercedes-Benz CLA45 AMG is a fast, competent car. It's significantly sharper than the Audi S3, and it should be, since its starting price is around $7,000 more. Still, getting walloped by the higher-performing CLA45 AMG must irk some people at Audi, we'd think, which might explain why there are rumors that the S3's big brother is coming to town. Yes, reports are popping up from an Audi of America employee that the Audi RS3 would transition from its Euro-market Sportback body style to a more conventional four-door, and that its styling would be updated in the process. Oh, and it'll have a 400-plus-horsepower, 2.5-liter, five-cylinder turbo with which to bash the four-cylinder AMG. The report comes from Quattro World by way of CarScoops, and goes on to claim that Audi hallmarks like Quattro all-wheel drive and a seven-speed S-Tronic dual-clutch transmission will both be present. The new RS3 Sedan would arrive on US shores in 2017 as a 2018 model, with prices starting between $55,000 and $60,000. That should make Mercedes-AMG very nervous – the CLA45 may start around $50,000, but getting it past the $60,000-range is simple (your author was driving a nearly $68,000 CLA45 just last month, for example). Naturally, we have a call in with Audi of America to see if there's any credence to this report. Stay tuned for updates. Related Video:
