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.

Next-gen Audi RS4 coming, might make it to America

Let us be frank: The second-generation Audi RS4 was one of the best, most exciting cars of the past decade. A four-door sedan with a 4.2-liter V8, all-wheel drive, and a six-speed manual transmission? What wasn't to like? While you can still get a taste of the B7 RS4's character with the current RS5, it isn't quite the same. That's why we're giddy about a new report from Car and Driver, which claims that not only is a new RS4 on the way, but that it could, maybe, possibly return to the United States. As previously reported, the fourth-generation RS4 will go back to a twin-turbocharged V6, after two generations of unassisted V8s under the hood. As per RS4 tradition, it will also be limited to a five-door Avant body style, because "that is what people expect from the RS4," Quattro GmbH boss Heinz Hollerweger told Car and Driver. An RS5 Sportback could also be in the offing, which might remain more true to the character of the first US-market RS4. The US question, though, remains an iffy one, largely because of the Avant shape. Audi has reduced the number of wagons it's offered in the US over the years, dropping the A4 and A6 Avant, although the former is sort of still offered in the form of the Allroad. But that position might be enough to keep the next-gen RS4 off our shores, although as the Quattro boss told CD the US market is changing and "there is more demand there [for wagons], so maybe that will change." Well, Herr Hollerweger, we're here to tell you that America loves wagons, and that you should put the next-gen RS4 on sale over here post haste. Danke.

German companies team up with telecom to spur development of talking cars

With connectivity and communications becoming an ever larger part of the automotive world, German automakers Audi, BMW, and Daimler formed the 5G Automotive Association with Intel, Nokia, Ericsson, Qualcomm, and Huawei. The goal is to develop new technologies to take advantage of LTE and 5G advancements, create standards, and overcome regulatory issues. If they succeed, it will be easier for them companies to develop and implement new technologies. For instance, we could see smarter traffic management, and maybe platooning, advance further in the autonomous sector. By acting as a group, they will also be able to address regulatory issues more easily. All of these companies are capable of developing advanced vehicle communication systems on their own. Audi, in fact, has been pursuing vehicle-to-infrastructure (V2I) technology and launched a stoplight timer in models in some cities. Still, the alliance offers the potential to save time and develop new ideas.
