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.

We demo Audi's Traffic Jam Assistant tech on the road [w/video]

The closer automotive technology comes to making good on the promise of fully driverless vehicles, the better we see just what difficult work reaching that ultimate goal will become. That's because, unlike so many other in-car technologies that need only integration into a vehicle, truly autonomous cars will also insist on involvement with the surrounding environment, fellow motorists, infrastructure in cities and other communities and making it all work without exposing automakers to law-breaking or tremendous possible litigation. Clearly that isn't all about to happen in one go.
At CES in 2012, Audi told us about a debuting technology that would mark a significant step along the path towards self-driving cars: Traffic Jam Assistant. This year, the German automaker invited us out to Las Vegas to see the jam-busting technology in action, on a relatively busy freeway.
The Traffic Jam Assistant (we're pretty sure that name is still in Beta) promises to relieve drivers from the tedium of slow-moving freeways by taking care of braking, acceleration and staying inside of the lane - all with no input from the human behind the wheel. While still a fair step from truly autonomous driving, the goal here is to give a commuter some respite from the mechanical, time-wasting traffic jam paradigm, potentially opening up a space for productivity in the process. (Audi can't come right out and say that TJA will allow you to use your cell phone in traffic, as that's still against the law in many places, but something like that is clearly on the radar... er... LiDAR.)

Audi planning A7 powered by fuel cell?

Back in March, Volkswagen AG CEO Martin Winterkorn voiced his doubts about the cost and infrastructure associated with building hydrogen fuel cell vehicles, but according to Autocar, that isn't stopping Audi from developing a fuel-cell version of the Audi A7. While we're inclined to take this report with a grain of salt, this wouldn't be the first time a VW executive has made seemingly damning statements about electric powertrains that later proved to be incorrect.
After speaking with Audi technical chief Wolfgang Dürheimer, Autocar reports that Audi is building a fuel cell A7 that is expected to be ready for testing by August. Like the electric E-Tron and natural-gas-powered G-Tron models, the hydrogen fuel cell Audis could, if produced, carry their own "tron" nomenclature.
