Audi S8 Plus packs 605 horsepower

Audi doesn't offer an RS 8, and probably never will. But with the release of the new S8 Plus, we wonder if it will ever have to. Because Ingolstadt's new flagship performance sedan packs a mighty punch. "Plus" doesn't even begin to describe the enhancements Audi and Quattro GmbH have wrought on the ultimate new version of the A8 sedan. Power is increased from 520 horsepower to 605, besting anything else in its class. Only the Mercedes S65, which packs four more cylinders and two additional liters of displacement, offers more horsepower. Torque is quoted at 516 lb-ft – a gain of 35 – and can deliver up to as much as 553 lb-ft in overboost. That bests any eight-cylinder performance sedan save the S63. The force-fed V8s in the Jaguar XJR, Maserati Quattroporte, and outgoing Alpina B7 don't stand a chance. All that muscle translates to a 0-62 time quoted at 3.8 seconds. Top speed is governed as usual to 155 miles per hour, but can be derestricted to nearly 190 with the Dynamic package that comes standard in Germany – one of the few places where top speed actually matters. Carbon-ceramic brakes keep all that power and pace in check, nestled inside 21-inch wheels. Naturally, Audi gives the S8 Plus a wide array of visual upgrades inside and out to set it apart from "lesser" versions, and is offering it in an exclusive matte silver finish. Of course none of those enhancements come cheap. In its home market come the end of November, Audi will charge 145,200 euros for the S8 Plus, representing a 28k premium over the existing S8. That also places this as the new top of the line, commanding a higher price than even the long-wheelbase, dozen-cylinder A8 L W12. We're waiting on word as to whether Audi will bring the new S8 Plus to America, where it would likely similarly cost over $140k. The pinnacle of sportiness – the new Audi S8 plus - Highest powered sport sedan in the premium segment - 4.0 TFSI engine outputs 445 kW (605 hp) and up to 750 Nm (553.2 lb ft) - Zero to 100 km/h (62.1 mph) in 3.8 seconds; top speed of up to 305 km/h (189.5 mph). Audi is making a strong statement with the new S8 plus*. With a power output of 445 kW (605 hp) and a top speed of up to 305 km/h (189.5 mph), the new Audi S8 plus* delivers even more enhanced driving performance. The new top model is reinforcing the brand's position in the segment of premium class sedans. "We have further sharpened our large sport sedan," says Prof. Dr.

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 R8, Lamborghini Huracan could get twin-charged five-cylinder

Engine downsizing and forced induction are some of the biggest trends in automotive powertrains today because. They offer the chance to reduce emissions and boost fuel economy, while possibly maintaining power. The shift is already happening to performance cars with turbocharged four-cylinders finding their way into the Ford Mustang, Chevrolet Camaro, and future Porsches. Now, there are rumblings of a tiny chance for a similar change coming for the Lamborghini Huracan and Audi R8. Why the new powertrain? China. While the market there might have slowing growth, it's still a major country for auto sales. The annual taxes on cars there also happen to be based on engine displacement, and there's a 40 percent rate on those over 4.0-liters, according to Car and Driver. The obvious answer to this conundrum is to build a smaller displacement, forced induction engine for the R8 and Huracan. Car and Driver points to the new turbocharged and electrically supercharged, 2.5-liter inline five-cylinder from the recent Audi TT Clubsport Turbo concept as a possible solution. Audi's e-turbo technology runs off a 48-volt electrical system and lithium-ion battery to produce a total of 600 horsepower and 479 pound-feet of torque in the prototype. With this mill, horsepower would barely shrink compared to the R8 V10 Plus and Lambo, but it actually makes more peak torque than their 5.2-liter V10s. While this is all theoretically feasible, take the possibility with a big grain of salt for now. According to Car and Driver, Quattro GmbH's Stephan Reil says that there's no work currently underway to fit the twin-charged five-cylinder, "but it has been talked about." That means such a vehicle is likely years away, if ever. In the meantime, a diesel version of the e-turbo setup is on the way the in the SQ7. Related Video:
