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.

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.

The pre-race and first in-race report from Le Mans

The 2013, 90th anniversary edition of the 24 Hours of Le Mans has begun, tragedy marking the opening laps with the death of Allan Simonsen. We're at the track now as a guest of Audi and plan to stay through the evening, and even we haven't been able to find out what caused the accident - the only video is from just after the incident, and beyond the statement from ACO there's been no more news. The Aston Martin in the LM GTE Am class and its all-Danish drivers had taken pole in its class and was one of the favorites to win.
The pre-race report will come first, and even thought we can't spoil the race because we're only five hours into it at the time of writing, we'll put all of the news at the end in case you don't even want the updates.
