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 A8 and S8 get another video tease

If there was any doubt before about which car(s) Audi recently teased in a video, now we know for sure. Audi has released another teaser video that confirms we'll at least be seeing the 2015 Audi S8 (and very likely the A8 as well) in the near future, but the big surprise is just how soon we'll see the new flagship sedan. We originally expected to see the sedan receive its official debut at the Frankfurt Motor Show, but now Audi says that the car will be presented about three weeks before the event on August 21.
How do we know this is the S8? Well, aside from it obviously being a large sedan, the true tell that this is its A8/S8 is the front license plate, which clearly shows "S8" on it - we've been doing this long enough to know that Audi's promotional license plates have the model designation in the plate number. As for other details, Audi's trick Matrix headlights shine through the thin veil in what should be the crown jewel of the sedan's new face. There's a little more than a week to go until the car is unveiled, but for now, check out the video below.

Audi A5 and S5 freshen up for 2017

UPDATE: A previous version of this story mischaracterized the 2017 S5's engine configuration. The article has been updated. Well, here's the new Audi A5 and S5. They look a lot like the old ones, but just a tiny bit better. In other words, the redesigned coupes received the same treatment as their four-door counterparts, the A4 and S4. While the German press materials mention both gas and diesel engines, we expect the A5 to carry on in the US with petrol power only. Like the current A5, a 2.0-liter, turbocharged four-cylinder will serve as the base engine, but will probably get a similar power bump as the A4 – Audi hasn't released official figures yet. The four-door had its base output bumped from 220 horsepower and 258 pound-feet of torque to 252 hp and 273 lb-ft of torque. The S5 is a more interesting proposition than the S4. Where the old S5's 3.0-liter, supercharged V6 produced 333 hp and 325 lb-ft of torque, the new, turbocharged, 3.0-liter six-cylinder pumps out 354 ponies, according to the global press materials. That figure, fans of the old 4.2-liter V8-powered S5 will note, is identical to the original S5 that came out for model-year 2008. Torque figures aren't available yet, but we'd bet on at least a small increase in torque. Still, the increase in power is good for a 4.7-second run to 62 miles per hour, a 0.2-second improvement over the current car's 0-60 time. Audi claims it will offer the A5 with both six-speed manuals and seven-speed dual-clutch transmissions, but we wouldn't be so sure about that stick here in the US. The only available gearbox on the A4 is a seven-speed S-Tronic – coupes are inherently more sporting than sedans, but we aren't sure that's justification for Audi to offer a manual-trans A5 here in the US. Audi only mentions an eight-speed automatic for the S5. So no, the German press materials aren't a good indicator of the US-market A5. What we can rely on, of course, are the official images. The original A5/S5 was a handsome car, but Audi's designers have done a swell job styling the 2017 model. It looks good, and is somehow even more refined than last year's car. Audi's new corporate grille works well on a coupe body, although the powerful creases in the hood might be a little too powerful. The tail is lovely, like a prettier A3. The bodies are better looking, but they're also lighter and more aerodynamic, too. The A5's coefficient of drag is down to a slippery 0.25, while Audi's engineers lipo'd 132 pounds of fat.
