2015 Audi S8

You've gotta hand it to the Audi A8. Last year, Mercedes-Benz launched the truly stunning S-Class, putting the rest of the high-dollar luxury flagship class on notice. With the brand-new S-Class turning heads and garnering all sorts of praise from the automotive press, classmates like the BMW 7 Series, Jaguar XJ and Audi A8 started to look, well, old. But Audi didn't see fit to just let its big sedan carry on and let the Mercedes take the cake.
So when Audi refreshed its A8 line for the 2015 model year with only minor updates, I kind of shrugged it off as just a quick way to keep the big sedan fresh until an all-new, hopefully S-Class-trumping version arrives. But then I drove the S8 pictured above, and I'm no longer so sure the Merc's shadow is as big and imposing as it once was.
Spoiler alert: the Audi S8 is simply fantastic.

Audi reveals new A3 Cabriolet with Quattro, S3 versions to follow

With the Frankfurt International Auto Show coming home to roost this week, German automakers aren't about to miss out on the opportunity to roll out their latest. Audi may be making the biggest splash with the new Sport Quattro concept, but will also use the occasion to introduce its latest compact convertible.
We just brought you the first leaked images of the new Audi A3 Cabriolet the other day, but now Ingolstadt has revealed the full thing. Slotting in below the A5 Cabriolet and replacing the previous A3 Cabriolet as the entry-level convertible in the Audi lineup, the new cabrio joins the A3 family as the fourth bodystyle in the range.
Based more closely on the sedan than the hatchback, the new A3 Cabriolet is a bit bigger than its predecessor in every dimension but height. Rather than go the folding hardtop route, Audi has stuck with its tried-and-tested hydraulic fabric roof mechanism that can open or close in just 18 seconds. But for the first time, Audi is offering the A3 Cabriolet with Quattro all-wheel drive, and - get this - will offer an S3 convertible version as well, complete with 300 horsepower and a 5.4-second 0-62 time.

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.
