Next Audi RS4 to get an electric turbo?

We don't yet know if the next Audi RS4 will come to the US, but whoever gets it could find an electric turbocharger under the hood according to a report in Auto Express. The 4.2-liter V8 that has served for two RS4 generations is retiring from the line, replaced by a twin-turbocharged version of the supercharged 3.0-liter V6 used in the S4. But instead of using two sequential turbochargers - a smaller one to eliminate lag while a larger, more powerful turbo spools up - batteries charged by brake regeneration could power a first-stage electric turbo. The idea hasn't been publicly appointed for a particular model, as Audi's technical chief Ulrich Hackerberg has said that due to expense, that kind of setup "would only be used be used on the very top end models." Since the technology cuts down on the use of exhaust gases, it would also also help in markets like Europe where CO2 emissions are a factor. No matter whether it benefits from all conventional or some electric boost, the horsepower number for the twin-turbo V6 will be more than 420 hp but less than 503 hp, the rating of the V8-powered Mercedes-Benz C63 AMG. Auto Express believes Audi will want to maintain the power gap between the 333-hp S4 and previous, 444-hp RS4. With Hackenberg saying the new S4 will make more than 350 hp, that gets the coming RS4 up to at least 461, but AE figures it "could deliver as much as 480 hp." We'll find out sometime after the S4 launches next year.

Auto Express gets close-up look at the 2016 Audi R8

Audi invited Auto Express to the Ascari circuit in Spain to get a ride in the new R8 that will be introduced at the Geneva Motor Show. Jack Rix starts by giving us a walkaround of the camouflage-covered coupe, the obvious difference between it and the leaked image from a couple of weeks ago being the slatted front intakes. However, those intakes are present on the image Audi teased showing off one new, slimmer, laser headlight. The biggest shock: there will be no V8 model at launch - there will be one engine in two levels of tune. The first is the 5.2-liter R8 V10 with 540 horsepower, a bump of 15 hp over the present car. The second is the 5.2-liter R8 V10 Plus with 610 hp, a leap of 60 hp over the current model. That hotter trim, identified by its fixed rear wing, drops the 0-60 mile per hour time by a half-second to 3.2 seconds, and increases top speed seven miles per hour to 205 mph. Rix ran his fingers along the intakes behind the door and said he could feel sideblades, so all is not lost - what would an R8 be without sideblades? More obviously, on the V10 Plus Rix looked over there are new trapezoidal exhaust tips framing a serious diffuser in back. Underneath, the aluminum chassis adapted from the Lamborghini Huracan is 15 percent lighter than before and 40 percent stiffer. Shifting will be done via a seven-speed S-tronic dual-clutch transmission only. There are seven driving modes, a switchable exhaust note, and more direct variable steering. The German test driver Rix rode with said the new R8 is easier to drive faster, which - no matter what you think of the looks - will make it pretty special.

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.
