300-HP 2013 Audi S3 Sportback unwrapped

Not content to let Volkswagen have all of the fun with its GTI and Golf R, Audi is rebooting its five-door S3 Sportback with rather monstrous power. Headed for an official unveil at this year's Geneva Motor Show, the new S3 rolls out with a 300-horsepower, 280-pound-feet of torque turbocharged 2.0-liter TFSI engine under the hood. The four-cylinder powerplant is strong enough to shove the Sportback to 62 miles per hour in just 5.0 seconds when connected to the optional S-Tronic gearbox, or 5.5 seconds with the traditional manual transmission. Top speed is said to be an electronically governed 155 mph. Almost as impressive as those performance figures are the fuel economy ratings: the S- S3 is said to average 34 miles per gallon.
All S3 Sportback models offer Quattro all-wheel drive, ride on a sport-tuned suspension tuned to a lower ride height (about one inch) versus the standard Audi A3. 18-inch wheels with 225-section tires are standard equipment, and 13.39-inch front brakes should offer serious stopping ability.
Audi has done a lot of work shedding pounds from this latest MQB-architecture S3, as well. The car has a curb weight of roughly 3,186 pounds, or some 154 pounds less than the outgoing model. 11 of those pounds were cut via weight-saving measures in the 2.0-liter engine.

Audi celebrates diesel milestone with triple-charged RS5 TDI concept

Diesels are typically slower than their gasoline counterparts, but leave it to Audi to turn that notion on its head. After dominating Le Mans and the international endurance racing scene under diesel power for the better part of a decade, the German automaker toyed with the idea of an oil-burning R8 for the road and ultimately made its first performance crossover a diesel. It's made the letters TDI a battle cry, and now it's yelling even louder with the RS5 TDI concept.
Set to be unveiled in a couple of days at the Leipzig Auto Show to celebrate 25 years of the TDI engine, the concept ditches the gasoline-burning 4.2-liter V8 in the production RS5 in favor of a 3.0-liter V6 twin-turbo-diesel with an electric supercharger added on to combat turbo lag. Output comes in at 385 horsepower and 553 pound-feet of torque, which means that while it has 65 fewer horses than the gasoline model, it packs a staggering 236 lb-ft more torque.
The result of the triple-charged madness is a 0-62 time around four seconds flat, trumping the 4.6 seconds for the road-going model. Top speed, of course, is electronically limited to 155 miles per hour, which is a bit of a shame because we bet it'd be a kick to pass a Porsche on the Autobahn in a diesel, now wouldn't it?

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.
